Joseph Ducan EXECUTED-Murdered Entire Family|Kidnap Son & burned his deadbody after 48days captive..
Convicted serial killer and molester Joseph Duncan will likely die before his federal death sentence is carried out. According to court documents, Duncan has terminal brain cancer as he sits on death row. He was convicted of killing four members of a family from Coeur d’Alene back in 2005.
He kidnapped those two you just saw, Dylan and Shasta Groene, from the family’s home, tortured them in Montana. Shasta Groene was the only survivor of the rampage and was rescued when Duncan stopped at a restaurant in Coeur d’Alene and Shasta was recognized by staff members. He’s been on federal death row in Indiana for years as his appeals move forward.
>> On the morning of May 16th, 2005, a neighbor pulled up to a small white house on Frontage Road near Wolf Lodge Bay, 8 mi east of Coeur d’Alene, Idaho. He had come to pay a 13-year-old boy named Slade Groene for mowing his lawn. No one answered the door. The family car sat in the driveway with their doors open.
Inside the house, a dog was barking without stopping. He called 911. When deputies entered the house, they found Brenda Groene, 40 years old, dead in the kitchen. Her son, Slade, was dead beside her. Her boyfriend, Mark McKenzie, 37 years old, was dead in the living room. All three had been beaten to death with a claw hammer.
All three were bound with nylon zip ties and duct tape. There was no sign of Brenda’s two youngest children, 9-year-old Dylan and 8-year-old Shasta. What followed was the largest criminal investigation in the history of Kootenai County. More than 100 FBI personnel, more than 80 investigators from multiple agencies, a $100,000 reward, an Amber Alert that ran for 7 weeks without a single confirmed sighting.
Volunteers searched forests, shorelines, and backroads across northern Idaho. Tracking dogs worked the terrain. A helicopter covered the area from the air. Tips poured in from across the region. Every one of them led nowhere. Seven weeks passed with no answers and no sign of the two missing young ones.
Then, shortly before 2:00 in the morning on July 2nd, 2005, a waitress named Amber Dean was working the third shift at a Denny’s restaurant in Coeur d’Alene when a tall, thin man walked in with a young girl. Something about the girl stopped her. She was quiet in a way that did not match her surroundings.
She sat at the table with her hands in her lap and her eyes down. Customers around the restaurant began to look at her more carefully. She looked like the girl from the billboards. She looked like the girl from the news. Several customers quietly called 911. Dean went to make a milkshake, the slowest milkshake she had ever made, while police were on their way.
Police arrived with their lights off. Three officers entered the restaurant and took the man at the table into custody without a struggle. His name was Joseph Edward Duncan III. He was 42 years old, a registered level three sex offender from Fargo, North Dakota, and a federal fugitive who had been on the run since April.
The girl at the table was Shasta Groene. She told Dean her name and started crying. Three days later, investigators announced that human remains had been found at a remote campsite in the Lolo National Forest in western Montana. On July 10th, the FBI laboratory in Quantico confirmed what everyone had already begun to accept.
The remains were those of Dylan Groene. He had been shot twice and his body had been burned at the campsite. Dylan had been taken from the same house as Shasta on the same night his mother, his brother, and Mark McKenzie were killed. He had been held at that Montana campsite for weeks. He had not survived. Shasta had.
From her hospital bed at Kootenai Medical Center, she gave investigators a account of 48 days that prosecutors later described as one of the most detailed and precise witness statements they had ever received from a survivor her age. Every detail she provided matched the physical evidence. Her testimony led investigators to the Montana campsite.
It identified the weapons. It described the surveillance. It placed Joseph Duncan inside the house on the night of the murders beyond any reasonable doubt. Duncan did not contest any of it. He pleaded guilty to every charge placed before him. Three murders in Idaho state court and in federal court, the kidnapping, abuse, and killing of Dylan Groene.
He represented himself during the sentencing phase. He stood before the federal jury and told them they had no idea of the full extent of what he had done. He described his intentions as going far beyond the Groene family. He named the other types of targets he had identified during his drive west. Daycare facilities, parking lots, campgrounds, private homes.
He told the jury he had been on a rampage. The jury deliberated for 3 hours. They returned three death sentences. Judge Edward Lodge sentenced Duncan to death on all three federal counts and imposed 12 additional life sentences without the possibility of parole. The state of Idaho added three more life sentences for the murders of Brenda Groene, Slade Groene, and Mark McKenzie.
He was transferred to federal death row at the United States Penitentiary in Terre Haute, Indiana to await execution. Prosecutor Tracy Whelan stood before the court and said it plainly, “This defendant is dangerous. He is a predator who takes pride in his work. He earned this day.” To understand how a man who had been described in a signed psychological report at age 17 as not safe to be at large ended up at a house on Interstate 90 42 years old with a stolen Jeep, a sawed-off shotgun, and night vision goggles, we have to go back.
Back to February 1963. Back to Fort Bragg, North Carolina. Back to the very beginning of Joseph Edward Duncan the Third. Subscribe to No Way Out, real cases, real people, every detail examined until the full picture comes into view. This is where true crime meets truth. Joseph Edward Duncan the Third was born on February 25th, 1963 at Fort Bragg military base in North Carolina.
He was the fourth of five children born to Joseph Edward Duncan Jr. and Lillian May Duncan. His father had joined the United States Army in 1958, a year after marrying Lillian in rural Burnham, Pennsylvania, and the family built its entire life around his military service. From the time Joseph the Third was old enough to understand the world around him, that world kept changing.
His father’s assignments moved the family from one posting to the next, sometimes within the United States, sometimes overseas. Every year or two, the Duncans packed up, relocated, and started over somewhere new. Joseph the Third attended a new school, made acquaintances, and moved again before anything could take root.
By the time he was around 12 years old, his father retired from the army and the family settled permanently in Tacoma, Washington. Tacoma was a working-class city on Puget Sound. Joseph the Third enrolled at Lakes High School, though he would not graduate. The constant movement of his childhood had left him without stable friendships or lasting connections.
He was, by most accounts, a quiet young man who had difficulty fitting in. At home, the dynamics were complicated. His mother, Lillian, was strict and domineering. His father’s military career had shaped the household around structure and discipline, but when that structure was removed after retirement, the home found no steady replacement for it.
The family had moved so many times that no outside relationships had taken root. No extended community, no neighbors who knew them well. No network of adults paying attention. Joseph Jr. grew up in a household that was, by any measure, closed in on itself. What happened inside it stayed inside it.
What was forming inside the youngest son was not visible to anyone looking from the outside, and there was almost no one looking from the outside at all. His parents’ marriage deteriorated through the late 1970s. They separated in 1979 and divorced in 1983. When the separation happened, his three older sisters left the home at once. Joseph III remained with his mother.
His younger brother eventually moved in with their father, who later remarried and started a new family. Joseph III found himself in a household that had contracted sharply, living with a mother whose strictness had not softened, and without the siblings who had been part of his daily life. He dropped out of Lakes High School without finishing his education.
By the time he was in his mid-teens, he was spending time on the streets of Tacoma with no clear direction. He had already developed a pattern of targeting younger boys in the neighborhood, approaching them in isolated settings and forcing sexual contact on them. In 1978, when Joseph Duncan was 15 years old, he committed the first recorded sexual assault of his life.
He approached a 9-year-old boy in Tacoma and raped him at gunpoint. He was arrested for that crime and sentenced as a juvenile. Rather than serving time in a detention facility, he was sent to Dislin’s Boys Ranch in Tacoma, a residential facility for troubled youth. There, he met with a therapist assigned to his case.
During those sessions, Duncan was candid. He told the therapist that he had bound and sexually assaulted six boys prior to his arrest. He also estimated that he had raped 13 younger boys by the time he was 16 years old. The therapist documented these statements and placed them in his formal record. In 1979, Duncan was arrested again, this time for stealing a car.
He was sentenced once more as a juvenile and cycled back through the system. Neither the sentencing nor the counseling slowed him down. He was approaching adulthood, and the pattern that had taken hold of him was already deeply entrenched. The staff at Dislin’s Ranch had documented his behavior, and the records showed a young man who went out of his way to seek victims.
As his therapist noted in one report, it was important to understand that Duncan actively looked for targets. He did not stumble into his crimes. He planned them. On the evening of January 24th, 1980, Joseph Duncan was 16 years old and living in Tacoma. The neighborhood he grew up in was working-class and close-knit, the kind of area where people knew their neighbors by name and left their doors unlocked.
Duncan knew a neighbor who lived nearby was away from home that evening. He had been watching the house. He smashed out a storm window and broke into the man’s bedroom. Inside, he found four Colt 45 pistols, approximately 1,000 rounds of ammunition, and a collection of pornographic magazines. He took all of it and walked back to his own home.
His original intention had been to return home, look at the magazines, and be done with it. He sat with the guns and the magazines for a period. Then he changed his mind. He loaded one of the stolen pistols, left the house, and walked out into the neighborhood looking for a victim. He found a boy walking near an elementary school close by.
Duncan pulled the gun on him and forced him at gunpoint into a wooded area nearby. What followed was not impulsive or disorganized. Duncan directed the assault with deliberate control. He forced the boy to perform sexual acts on him twice. Between the two assaults, he struck the boy repeatedly with a stick he picked up from the ground and burned the boy’s skin with a lit cigarette.
He was not in a panic. He was not out of control. He was methodical. When he had finished, he walked the boy back to his clothing, told him to run, and left. Duncan went home. The police were already waiting at his front door. Investigators had moved quickly after the boy reported what had happened. Duncan was taken into custody that night.
The stolen weapons were recovered from inside the house. He was charged as an adult despite being 16 years old. The offenses were serious enough that prosecutors pursued the case in adult court. He pleaded guilty to first-degree rape with a firearm and first-degree burglary. The sentence handed down was 20 years in prison, though the judge initially suspended it.
Rather than sending him directly to an adult prison, the court ordered a 90-day evaluation at Western State Hospital, a psychiatric facility near Tacoma, to determine whether Duncan met the legal definition of a sexual psychopath. The evaluation would determine the next step.
The evaluation concluded that he did. The psychological report produced at Western State Hospital was detailed and direct. Duncan was 17 at the time of his formal assessment. The evaluators noted that he was preoccupied with deviant sexual fantasies and that his behavior met the clinical definition of a sexual psychopath.
What made the report particularly significant was the information Duncan himself provided. During his clinical sessions, he gave evaluators a detailed sexual history that went far beyond the crime for which he had been arrested. He described sexual contact beginning at age eight involving female relatives. By 12, he said, he had forced a younger boy in the neighborhood to perform a sex act on him.
At 15, he had done the same to a 9-year-old at gunpoint. The assault for which he was currently being evaluated was not his first. It was not his second. It was not even close to the beginning. The report stated clearly, “It is important to note that Mr. Duncan did go out looking for victims.” It also stated, “Mr.
Duncan is not safe to be at large.” Clinical Director Dr. William Vorhies Jr. and his colleagues documented their findings thoroughly. They wrote that Duncan’s pattern of seeking power over younger boys had developed into what they described as a very powerful and compulsive pattern. They noted his antisocial personality structure, his capacity for calculated violence, and the deliberate nature of his offending.
Their conclusion was unambiguous. Joseph Duncan posed a serious danger to any community in which he lived freely. They recommended commitment to the sex offender program at Western State Hospital for structured treatment rather than immediate transfer to prison. He was committed to the program. Western State Hospital’s sex offender program was designed to provide intensive therapeutic intervention for men whose offending behavior was rooted in deep psychological disturbance.
The program used group therapy, individual counseling, and behavioral monitoring. Participants were expected to engage honestly with the process, confront their patterns, and work toward modifying their behavior. For 22 months, Duncan remained inside that program. He did not engage honestly. He did not confront his patterns.
Staff members discovered that Duncan was sneaking off the hospital campus without authorization on a regular basis. When this was investigated, it became clear that he had been leaving the grounds to act out the same violent rape fantasies that had brought him to the program in the first place. He was not suppressing those urges inside the hospital.
He was indulging them outside it while presenting a surface of cooperation to the staff. The program structure was being used as cover, not as treatment. By 1982, Western State Hospital had reached the end of what it was willing to do with him. The program formally discharged him. Officials communicated to the court that Duncan was not amenable to treatment and had not modified his behavior in any meaningful way.
The judge responded by reinstating the original 20-year prison sentence in full. Duncan was transferred to the Washington State Penitentiary to begin serving his time as an adult inmate. He was not yet 20 years old when he arrived. The Washington State Penitentiary in Walla Walla was a maximum security facility housing some of the most dangerous men in the state’s prison population.
Duncan entered the general population and struggled immediately. His behavior during the initial years was disruptive and dangerous. Prison records documented infractions for assault, weapon possession, and substance abuse. A pattern that reflected the same contempt for rules and authority he had shown at Western State Hospital.
He presented himself to staff and fellow inmates in different ways at different times. At one stage, he identified as a transsexual. At another, he identified as gay. The Washington Department of Corrections psychologist who later reviewed his complete file noted that these shifting self-presentations had not helped Duncan adjust within the prison environment where identity and consistency carried significant weight.
Despite the disciplinary problems, Duncan was not without discipline when it suited him. He applied himself to the prison education program and earned his high school diploma in 1982 at the Washington Corrections Center in Shelton, the same year he entered the adult system. The diploma was a genuine academic achievement and it reflected something that would become a recurring feature of his profile, the capacity to function at a high level in one area of life while everything else deteriorated around it.
He was intelligent. He could apply himself. He chose when to do so and when not to. Over the following decade, he was moved through five different prison facilities across Washington state. Each transfer brought new staff, new assessments, and new opportunities for Duncan to adjust his presentation.
He learned how institutions worked. He learned what evaluators wanted to hear. He learned how to describe his past and his intentions in ways that suggested progress without constituting it. In 1993, with his eventual release date approaching, prison staff discovered that Duncan had attempted to forge a corrections document.
He had obtained access to paperwork describing his offense and altered the description from rape to assault. His stated reason was practical. He was afraid that other inmates who knew the true nature of his crime would target him. The explanation was plausible enough on its surface. The act itself was something else entirely.
It was evidence of a man who understood exactly what his record said about him. Who understood that it carried consequences and who was willing to falsify official documents to manage those consequences. The forgery was caught, documented, and added to a file that was already thick with evidence of who Joseph Duncan was. Joseph Duncan spent 12 years working through Washington State’s prison system.
He cycled through five different facilities and the records that followed him painted a consistent picture. He was manipulative. He was intelligent. He presented himself differently depending on his audience. He told evaluators what they needed to hear and then behaved in ways that contradicted everything he had told them.
He earned his high school diploma. He participated in educational programs. On the surface, he was a model prisoner when it suited him. Prison staff noted that he could be cooperative, articulate, and persuasive. An NDSU professor who later knew him in Fargo described this quality precisely. Duncan was able to communicate in ways that made people believe he had changed when he had not.
That, the professor said, was the mark of a true psychopath. His parole was granted in late December 1994 after he had served 14 years of his 20-year sentence. Duncan was released into a supervised parole arrangement in Washington State. He found work as a telemarketer at a Time Life Library service in Seattle. His parole officer, Sandra Silver, began monitoring his behavior.
For a period, things appeared stable, but within a year and a half of his release, Silver grew concerned. Duncan was required to submit to polygraph tests every 90 days as a condition of his parole. During one of those tests, he disclosed sexual contact with at least 10 different men since his last examination. His therapist, a Seattle counselor named Glenn Pressel, was aware of Duncan’s behavior and had apparently permitted it.
Silver sent a formal letter to Pressel questioning how allowing Duncan to engage in what she described as promiscuous bathhouse sex was consistent with treating his sexual deviancy issues. The tension between Silver and Pressel over Duncan’s supervision reflected a deeper problem. A 1999 psychological evaluation would eventually classify him as high risk, noting sadistic and psychopathic traits predicting ongoing danger.
But that evaluation had not yet been written, and in 1994-1995, Duncan moved through Seattle with minimal effective oversight. He lived in several locations in the Seattle area during his parole years. He moved around, maintained loose contact with his supervision requirements, and continued to function in the city without drawing attention.
Then, in July 1996, two young girls disappeared from the Crest Motel in Seattle. Sammie Jo White, who was 11 years old, and her half-sister Carmen Tubbs, who was 9, left the motel one evening to walk to a nearby restaurant. They never came back. Their families reported them missing, and investigators launched a search.
Days passed with no sign of them. 17 months later, in February 1998, skeletal remains were found in Bothell, a suburb north of Seattle. Forensic testing confirmed the bones belonged to Sammy Yeo and Carmen. They had been murdered. No suspect was identified. The case went cold. Meanwhile, Duncan’s parole continued then unraveled. In October 1996, Duncan tested positive for marijuana during a routine parole check.
He also had a firearm in his possession, a direct violation of his parole conditions. His parole was revoked temporarily, then reinstated with additional restrictions. He tested positive for marijuana again shortly after and this time he stopped reporting to his parole officer entirely. He went on the run in March 1997.
The following month, on April 4th, 1997, a 10-year-old boy named Anthony Michael Martinez was playing with a group of friends in the front yard of his family’s home in Beaumont, California in Riverside County. A man approached the group and said he was looking for a missing cat. He offered them a dollar to help him search.
When the boys refused, the man grabbed Anthony and forced him into his vehicle at knife point. Anthony’s friends watched the car drive away and ran immediately for help. A 2-week search followed. On April 19th, a forest ranger found Anthony’s body in the desert near Indio, approximately 70 miles east of Beaumont.
He had been bound with duct tape and had been sexually assaulted. Investigators collected a partial fingerprint from the duct tape. There were no immediate suspects. The case was opened and logged but produced no arrest. Anthony Martinez was buried and his family waited for answers that did not come. Duncan was arrested in Missouri in 1997 for violating his parole.
He was returned to Washington State Prison. Neither the Seattle case nor the Beaumont case was connected to him at that time. Joseph Duncan walked out of the Washington State prison system on July 14th, 2000. He had served an additional 3 years on his parole violation and was 37 years old. He had spent all but 6 years of his adult life behind bars.
He had no job, no established home, and no supervision waiting for him on the other side of the gate. Despite his classification as a level three sex offender, the highest risk category under Washington State guidelines, reserved for offenders considered most likely to re-offend, Duncan was released without probation oversight.
A state evaluation conducted in 1999 had been direct about what he represented. The psychologist, Xavier Chan, documented sadistic and psychopathic traits and placed him in the high-risk category. The evaluation noted that his patterns of offending were deeply entrenched and that the likelihood of future criminal behavior was significant.
Washington State had a sexually violent predator statute that could have been used to pursue civil commitment for someone with Duncan’s profile. It was not applied. He was released, pointed toward Fargo, North Dakota, and left to manage himself. He arrived in Fargo and registered as a sex offender 3 days later, as required by law.
The Fargo Police Department responded by holding what was believed to be the city’s first-ever sex offender community notification meeting, informing residents in the area where Duncan had settled about his presence and his history. The meeting produced unease in the neighborhood. Residents gathered to discuss what it meant to have a level three sex offender living among them.
At least one community meeting was organized among concerned families. The anxiety was real and documented. Duncan watched all of it and adjusted his behavior accordingly. He enrolled at North Dakota State University in the fall of 2000 as a computer science student. He attended classes, completed assignments, and performed well enough to make the Dean’s list.
He worked part-time as a computer software developer for a local company. He also registered for academic research work under a faculty member at the university. He paid his rent. He registered his address. He showed up where he was supposed to show up. He befriended people along the bike trails around Fargo, including Joe Crary, a well-connected businessman who was a former executive member of the Fargo-Cass County Economic Development Corporation.
Crary came to regard Duncan as a friend. Duncan’s landlord, having learned of his sex offender registration, gave him a second chance after Duncan explained his past as the mistake of a young and foolish 16-year-old who had struggled with anger issues. The landlord accepted the explanation. The Fargo community, by and large, accepted the person Duncan presented to it.
In 2004, Duncan began publishing an online journal he called Blogging the Fifth Nail. The title drew on a piece of religious lore he had made his own. According to the story, in addition to the four nails used to crucify Jesus Christ, there was a fifth nail that the Romans removed and concealed.
Duncan applied this image to himself, framing his hidden nature as a truth the world was not yet capable of understanding. The blog gave him a public platform and an audience. He posted entries in the middle of the night, writing in a confessional, searching tone about his experience as a registered sex offender. He described the social stigma he faced wherever he went.
He wrote about his frustration with the legal system and with the way society treated people who had been convicted of sexual offenses. He described what he called an ongoing internal struggle between right and wrong. In one entry he wrote, “I have decided to give up on trying to convince people that I am a real person with honest and good intentions, not some evil monster they should be afraid of.
” The entries were read by a small audience. Some readers found them thoughtful. Some found them disturbing. Alongside the public blog, Duncan maintained a separate encrypted record on his computer. He had protected the contents with software strong enough to make access extremely difficult. Whatever he was storing on those drives, he had taken deliberate steps to ensure that no one could read it without his permission.
On July 3rd, 2004, a man approached two young boys at a playground connected to Roosevelt Elementary School in Detroit Lakes, Minnesota, approximately 50 miles east of Fargo. The man carried a video camera. He approached the boys, pulled down the shorts of one of them, and touched him. The boys ran immediately and reported what had happened to adults nearby.
A police investigation was opened. Detectives worked through the case over the following months. By March 2005, they had identified Duncan as their suspect. A summons was mailed to his Fargo address. He was formally charged with criminal sexual conduct in the second degree and attempted criminal sexual conduct, both felonies under Minnesota law.
On April 5th, 2005, Duncan appeared before Judge Thomas Schroeder in Becker County District Court in Detroit Lakes. His defense attorney, Dennis Fisher, presented the court with a picture of a responsible, stable resident. He told the judge that Duncan was a student close to completing a computer science degree at NDSU, that he worked two jobs, that he had been cooperative supervision requirements, and that the Fargo Police Department had visited him as recently as the previous week and found him entirely law-abiding.
Fisher asked for a $10,000 bail with a 10% cash option, arguing that Duncan’s community ties and compliance record justified a minimal restriction. The prosecutor, Assistant Becker County Attorney Mike Fritz, asked for $25,000. Judge Schroeder set bail at $15,000. No one in that courtroom told the judge Duncan was classified as a level three sex offender.
The distinction between being a registered sex offender, which the defense acknowledged, and being classified at the highest possible risk level, was never communicated to Schroeder. Without that information, the judge made the decision the facts in front of him supported. Duncan produced a personal check for $15,000 and walked out of the courthouse.
Duncan left the Becker County Courthouse with the check written and his freedom intact. He had walked in that morning facing two felony charges and walked out two hours later with nothing more than a court date and a weekly check-in requirement. The $15,000 check he had written at the clerk’s window was personal, drawn against an account that did not have $15,000 in it.
He had written it anyway, signed it, handed it over, and kept moving. The check would clear or it would not. He needed to make a call. He sat in his car outside the courthouse and called Joe Crary. Crary was 51 years old and well-established in Fargo. He had served as a former executive member of the Fargo-Cass County Economic Development Corporation and moved comfortably in the city’s business circles.
He and Duncan had met on the bike trails that wound through the Fargo area, the kind of casual outdoor setting where conversations happen naturally and people present their best selves. Duncan had presented his best self. He had told Crary about his past in the way he told everyone about his past, as a story of a young man who had made a serious mistake, paid for it, and was now doing everything right.
He was studying computer science. He was working. He was putting in the hours that rebuilding a life required. Crary had believed him. He had come to regard Duncan as someone worth investing in, someone the community should support rather than reject. When Duncan called from the courthouse parking lot and explained that he needed the bail covered before the check bounced, Crary did not hesitate.
He drove to Detroit Lakes that same afternoon, sat down with Duncan, and wrote a personal check for $15,000 on the spot. He handed it over without conditions. The bail was covered. Duncan’s check cleared. His freedom held. Crary later said he had done similar things for others before, that financial support for people trying to rebuild their lives was something he believed in.
He had no reason, based on what Duncan had shown him, to doubt the man sitting across from him. The Fargo Police Department had visited Duncan’s address the previous week and found him law-abiding. His attorney had stood in court that morning and described him as a model resident. The judge had set a bail amount that implied a manageable level of risk.
Everyone in Duncan’s orbit had accepted the picture he had constructed, and Crary had accepted it, too. The check was written. The two men parted ways. Duncan drove back toward Fargo with $15,000 of someone else’s money covering his freedom and a court date on May 16th that he had no intention of fleeing.
Judge Schroeder had attached conditions to the release. Duncan was ordered to check in with a corrections agent, Larry Boomgarden, once a week. He was ordered to return to court on May 16th, 2005 for the next scheduled hearing. He signed the paperwork, agreed to the conditions, and drove back to Fargo. Boomgarden made his scheduled check-in visits.
Duncan attended every appointment without complaint. He was cooperative and gave no indication that anything had changed in his daily life. Boomgarden found nothing to flag. Behind that compliance, something else was happening. Duncan had already stopped attending his academic research meetings at NDSU in late February 2005.
The retainer check he had written to his defense attorney had bounced. He had quietly begun to disengage from the structures that had defined his Fargo life for 5 years. On April 13th, 2005, 8 days after the bail hearing, Duncan walked into a Walmart store in Fargo and made a series of purchases.
Night vision goggles, a video camcorder, recording tapes, a radar detector, and a car battery. He paid for them in cash and left. On April 15th, he rented a red 2005 Jeep Grand Cherokee from a rental agency. On April 21st, he disappeared from Fargo entirely. He did not contact Boomgarden. He did not reach out to his attorney.
He walked away from his apartment, his university registration, and the community that had accepted him, and he did not look back. He drove the Jeep east into Missouri, moving without a fixed destination. On April 27th, he stopped in Newton County, Missouri and stole a set of license plates from a vehicle parked nearby, switching them onto the Jeep to obscure its identity.
By May 4th, the rental agency had reported the Jeep stolen. Duncan kept driving. He had maps. He had a GPS unit. He had waypoints marked at locations along his route. Addresses and coordinates he had identified in advance as potential targets. He had a sawed-off shotgun. He had the night vision goggles, the camcorder, and the radar detector.
He drove west on Interstate 90, cutting through the mountain states, moving toward Idaho. On May 13th, 2005, he posted the final entry on his blog. “My intent is to harm society as much as I can, then die,” he wrote. He also described the encrypted journal on his hard drive, writing that he had left a complete record of who he was, what he had done, and what he had thought.
Sealed inside encryption that would not be broken for decades. He described it as a message to the future. Then he closed the laptop and kept driving. Two days later, on May 15th, 2005, he was in Kootenai County, Idaho. Joseph Duncan had been driving west on Interstate 90 for days, moving through the mountain states with waypoints marked on his GPS and a stolen Jeep carrying stolen plates.
He had left Fargo on April 21st with no intention of returning. He had left behind an apartment, a university registration, a court date, and 5 years of carefully constructed appearances. None of it had ever been real. It had all been preparation for something else. And that something else was now in motion. He drove through South Dakota.
He drove through Wyoming. He moved through the wide-open stretches of the mountain west with the sawed-off shotgun within reach and the night vision goggles in the back. The GPS unit on the dashboard tracked his position and stored the waypoints he had marked in advance. Locations he had identified as potential targets during the weeks of planning that had preceded his departure from Fargo.
He was not driving randomly. He was working through a list. At some point during the second week of May 2005, he came off Interstate 90 into the Wolf Lodge Bay area, approximately 8 miles east of Coeur d’Alene, Idaho. The exact reason he exited at that particular point was never established. He may have needed to stop.
He may have been scanning the area deliberately. Whatever pulled him off the highway, he found himself on Frontage Road, a quiet two-lane road that ran parallel to the interstate and served the small residential properties tucked against the hillside above Lake Coeur d’Alene. The road was the kind that slowed a driver down naturally.
The properties along it were modest and close together, set back from the pavement behind short driveways and bordered by trees and brush. The hills rose on one side. The lake sat below on the other. It was a neighborhood designed for quiet living. And it looked exactly like that from the road. Duncan drove slowly.
He passed a small white cinder block and frame house with green trim. The lower portion of the walls had been finished in stucco, giving the house a smooth, even appearance at the base. The property was somewhat sheltered. Trees stood on multiple sides, and the surrounding brush created a natural screen between the house and the road.
The yard opened up between the front of the house and the road, flat and open, with a swing set visible near one side. And in that yard, in the warm afternoon of a mid-May day, two young ones were playing outside in bathing suits. Duncan stopped the Jeep. He sat at the side of the road and watched. Then he pulled away and drove on.
But he did not leave the Wolf Lodge Bay area. He came back to Frontage Road. He came back the next day. He came back again after that. Before describing what happened in the days that followed, it is important to understand the people who lived inside that house, who they were, where they had come from, and what their lives looked like in the spring of 2005.
Brenda Kay Groene was 40 years old. She had been born in Idaho and had spent her entire life in the region. She had grown up in the kind of community where people stayed close to where they were raised, where family networks ran deep, and neighbors were known by name for decades. She had married young, started a family, and built her adult life around her children.
By the time she was living on Frontage Road, she had five children ranging from toddlers to young adults, and the three youngest were her daily responsibility and her daily focus. Her marriage to Steve Groene had produced three of her children, Slade, Dylan, and Shasta. The marriage had ended in divorce, and Steve Groene was living separately from the family by 2005.
He remained connected to his children and was part of their extended lives, but the day-to-day household on Frontage Road belonged to Brenda. She ran it. She managed the bills, the meals, the school schedules, and the hundred small decisions that kept a household with young people functioning. People who knew her described her as fully present in that role, not someone who outsourced the work of parenting or kept her distance from the details.
She was there every day in the way that mattered. Her oldest children, Vance and Jesse, were adults by 2005. Jesse, who was 18, was not living at the Frontage Road house. He was incarcerated at the Kootenai County Jail during this period, a fact that added a particular dimension of grief to what he experienced when news of the murders reached him.
He heard from inside his cell that his mother and his brother Slade were gone. He told reporters what he knew of her in the simplest possible terms. “She was a good mom,” he said. Mark McKenzie was 37 years old. He had come into Brenda’s life in the years following her divorce from Steve Groene, and the two had built a relationship that deepened steadily over time.
By 2005, they were engaged. The Frontage Road house was their shared home, and the arrangement was understood by everyone who knew them as a permanent one. Mark had integrated into the family in the way that takes time and consistency, not by arrival, but by accumulation, by showing up reliably, by becoming familiar to the children and to the neighbors and to the extended network of people who moved through Brenda’s life.
He worked steadily. He was not a man who drew attention to himself. The people who knew him described him as even-tempered and dependable, someone you could count on to follow through on what he said he would do. He and Brenda complemented each other in the practical sense. She managed the household and the children, he contributed his income and his presence, and together they made the Frontage Road property feel like a functioning and stable home.
Slade Groene was 13 years old. He was the oldest of the three children still living at home, and he carried himself with a particular combination of boyish energy and emerging responsibility that belongs to that age. He was physically active and outdoors-oriented, comfortable moving through the neighborhood on his own, and trusted by the adults around him to do so sensibly.
He had built a small but genuine reputation in the immediate area as a young person willing to work. He mowed lawns for neighbors on Frontage Road and in the surrounding streets, showing up when he said he would and doing the job properly. A neighbor who arrived at the Groena house on the morning of May 16th, 2005, came specifically to pay Slayde for a recent mowing job.
That was the kind of impression Slayde had made on the people around him. Reliable enough that payments were expected and planned. He was also social in the easy way of young people who grew up in small communities where everyone knew each other. He moved between households on the street without self-consciousness, knew the neighbors by name, and was well-liked by adults and peers alike.
Dylan and Shasta were the two youngest members of the household. They were close enough in age to spend most of their time together, and the Frontage Road property gave them the kind of freedom that came with semi-rural living. The yard was large enough for play. The road in front of the house was quiet enough that the adults did not worry about them being near it.
The neighborhood itself carried no particular sense of danger. Families on that stretch of Frontage Road left their doors unlocked. Young ones rode bikes and played outside without needing to be watched from the porch. Dylan and Shasta made full use of that freedom. They spent their days outside in the warm spring weather, playing in the yard and along the road.
One of their regular amusements was standing near the highway above and flagging down passing semi-trucks, waiting for the drivers to respond with a blast of the air horn. They laughed every time a driver obliged. It was the kind of unself-conscious, uncomplicated joy that belongs to young ones who have no reason to be anything other than happy.
The house they all lived in was modest in the way that the houses on Frontage Road were modest. Built for function rather than appearance, furnished with the practical items of a working family’s life. A dog lived at the property and was part of the daily rhythm of the household. The family followed a regular schedule.
School days had their routine. Weekends brought errands and social occasions. Brenda cooked, Mark worked, Slade took his jobs, Dylan and Shasta played. That was the life inside the house on Frontage Road. That was what existed on that property before Joseph Duncan drove past the yard on a warm afternoon in May and stopped his Jeep.
Over the two to three days that followed his first pass down Frontage Road, Duncan established a surveillance routine. He returned to the area each day and parked at a distance, far enough back to observe without being seen. He watched the house through the daylight hours, tracking the movement of each member of the household.
He noted the times Brenda left and returned. He watched Mark McKenzie’s comings and goings. He observed Slade moving around the yard and driveway. He watched Dylan and Shasta playing outside in the afternoon warmth, their voices carrying across the yard. At night, he moved. He left the Jeep parked away from the house and approached on foot in the darkness, using the night vision goggles from the Fargo Walmart, to look through the windows of the house.
He studied the interior room by room. He identified where the bedrooms were, where people slept, where the family gathered in the evenings before the lights went off. He mapped the house from the outside, building a precise understanding of its layout and the habits of the people inside it, so that when the time came to move, he would not be operating in the dark in any meaningful sense.
On Saturday, May 14th, 2005, the family drove into Coeur d’Alene together in the afternoon to run errands. They came back to the house and spent the rest of the day preparing for a backyard barbecue. Friends arrived that evening. A fire was lit, food was shared around the yard. The gathering was warm and easy, the [music] kind of late spring social occasion that marked the beginning of the outdoor season in northern Idaho.
The conversation moved between people who knew each other well. The fire burned down slowly. By the time the evening ended and the guests drove away, the house settled into its ordinary night time quiet. Duncan was outside in the darkness when the last guests left. He watched the lights go off one by one. The following morning, Sunday, May 15th, the family moved through a quiet day at the house.
There were no events and no visitors. The household followed its natural rhythm through the afternoon and into the evening. As the night came on, the lights went off room by room. The property grew still and silent. Shortly before dawn on the morning of Monday, May 16th, Duncan moved toward the house for the last time as an observer. He was no longer observing.
He wore dark gloves. Pulled tight over his hands, they left no prints on anything he touched. He carried a 12-gauge shotgun and had the Fat Max claw hammer secured on his person. He carried nylon zip ties in quantity and had duct tape ready. He knew the floor plan. He knew where each room was. He had watched this house for days and had studied its interior through its windows on multiple nights.
He moved across the property and entered the home. What happened inside that house in the hours before dawn was later pieced together from physical evidence and from Shasta’s account. Duncan entered the home in the early morning darkness. He moved through it quickly and quietly using the knowledge of its layout he had built over multiple nights of surveillance, he located McKenzie and Slayed first and restrained them both with nylon zip ties and duct tape, binding their wrists and ankles and leaving them on the floor unable to
move freely. He then found Brenda Groene. With the shotgun on her, he walked her to Shasta’s bedroom and made her wake her daughter. Brenda had no choice. She went into the room, woke Shasta, and walked her to the living room. When Shasta came through the doorway, Duncan was there. He then restrained Brenda with zip ties and duct tape as he had done with McKenzie and Slayed.
All three adults were now bound and on the floor. Duncan bound Shasta and Dylan next. He took them outside and placed them on the ground near the swing set at the side of the yard. The air was cool. The property was dark around them. The highway above carried the faint sound of an occasional passing vehicle. From the ground beside the swing set, Shasta heard what was happening inside the house.
She heard McKenzie call out in pain. The sounds came more than once. Then the front door opened and Slayed came out into the yard. He was bleeding and his movements were disorganized. Shasta and Dylan called to him to help untie them. He could not respond. He could not help them. He could not stay upright. The door stood open behind him.
The sounds from inside the house went on for a period. Then they stopped. Duncan used the Fat Max claw hammer on all three. He killed Brenda Groene, Mark McKenzie, and Slayed Groene separately while the two youngest members of the family lay tied in the yard outside. When it was finished, he walked back out through the door.
He walked to Shasta and Dylan. He picked them up and moved them to a pickup truck he had parked nearby, then transferred them to the red Jeep Grand Cherokee. He loaded them in, got behind the wheel, and pulled away from Frontage Road. He headed back to Interstate 90 and drove east, then turned north, moving away from Wolf Lodge Bay with the two youngest members of the Groene family in the vehicle beside him.
Behind him, the house on Frontage Road sat dark and motionless. Brenda Groene and Slade Groene lay dead in the kitchen. Mark McKenzie lay dead in the living room. All three were still bound with the zip ties and duct tape Duncan had applied in the final hour before dawn. The swing set stood empty in the yard. The family dog moved through the silent rooms of the house alive, barking at nothing and everything, waiting for someone to come.
The morning of May 16th, 2005, began quietly in the Wolf Lodge Bay neighborhood. A neighbor came to the Groene house sometime that afternoon to pay Slade Groene for mowing his lawn. It was a routine transaction. Slade was known in the area for yard work, and payment had been arranged. When the neighbor arrived, no one answered the door.
The family cars were still parked in the driveway, both with their doors open, which was unusual. Inside the house, a dog was barking without stopping. There was no sound of movement from anyone in the family. The neighbor did not investigate further. He called 911. Kootenai County Sheriff’s Detective Brad Maskell had taken the day off.
It was his 50th birthday, and he had just completed a demanding case. He was at home relaxing when his phone rang at around 6:30 in the evening. The on-duty patrol commander was calling. Maskell assumed at first it was a prank. The idea of a triple murder in the Wolf Lodge area seemed impossible. The commander’s tone made clear it was not.
“We need you,” he said. When Maskell arrived at the scene with other investigators, deputies had already entered the house. They found the bodies of Brenda Groene and Slade Groene in the kitchen. Mark McKenzie’s body was in the living room. All three were bound with zip ties and duct tape.
All three had died from blunt force trauma to the head. There was no sign of Dylan or Shasta anywhere on the property. Deputies sealed the house and posted sentries. The road in the vicinity was closed. The area was designated a crime scene. Crime scene technicians and homicide investigators returned at dawn on May 17th and worked through the property systematically.
Corners confirmed the identities of the three victims and placed the approximate time of death as sometime late on May 15th or in the early hours of May 16th. Investigators canvassed the neighborhood and interviewed everyone connected to the family. The picture that emerged was of a family with no obvious enemies, no known feuds, and no clear reason for anyone to want them harmed.
An Amber Alert was issued nationwide for Dylan and Shasta Groene. Their photographs went out across the region on billboards, on television broadcasts, on posters in store windows, and on telephone poles throughout northern Idaho and the surrounding states. The Kootenai County Sheriff’s Office launched what quickly became the largest criminal investigation in the county’s history.
Within days, more than 100 FBI personnel and more than 80 investigators from multiple agencies joined the effort. Volunteers from the Kootenai County Search and Rescue combed the wooded areas surrounding the Groene house and searched along the shores of Lake Coeur d’Alene. Teams went out on foot, on horseback, and on all-terrain vehicles.
Trained tracking dogs and cadaver dogs worked the terrain. A helicopter covered the area from the air. On May 18th, a person of interest surfaced. A 33-year-old man known locally as Concrete Bob. His real name was Robert Roy Lautner, a construction worker, had visited the Groene house twice in the days just before the murders.
Once on the Friday afternoon before the killings and again on Sunday evening, which appeared to be close to the time of the attack. A relative told detectives that Lautner owed Brenda Groene and Mark McKenzie $2,000. Investigators needed to speak with him urgently, but first they had to find him. Robert Roy Lautner had a criminal record and had been seen at the Groene-McKenzie home twice in the days before the murders.
For several days, he was the most significant person of interest in the investigation. Detectives traced his movements, interviewed his associates, and worked to locate him. Lautner had spoken to his probation officer by telephone on May 18th, the same day investigators identified him as a person of interest.
He said he was traveling to Boise. He had already heard about the murders and was reportedly in tears when speaking to a family friend of the victims. When investigators caught up with him, he cooperated fully. He agreed to take a polygraph examination. He passed. Investigators removed Lautner from their list of suspects.
The $2,000 debt, his visits to the house, and his absence after the killings had all pointed toward him. But the polygraph results and the absence of physical evidence connecting him to the crime scene took him out of consideration. The investigation shifted back to open territory. Detectives had no physical evidence pointing to a specific suspect.
They had a crime scene with three dead victims, two missing young ones, no witnesses, and no clear motive traceable to anyone in the family’s immediate circle. The working theory that someone who knew the family had committed the murders was no longer supported by the available facts. The FBI brought in additional resources.
Tips poured in from across the region. Investigators followed every lead that came through the tip line. Some pointed to specific individuals. Others were vague. All were followed up and cleared. The search for Dylan and Shasta continued through the final days of May and into June. The FBI offered a $100,000 reward for information leading to the safe recovery of the two young ones. Six weeks passed.
Seven weeks. Then, shortly before 2:00 in the morning on July 2nd, 2005, a young girl walked into a Denny’s restaurant in Coeur d’Alene accompanied by a tall, thin man. It was a Friday night, or more precisely, an early Saturday morning, and the restaurant was starting to fill with people coming in after the bars had closed.
Waitress Amber Dean was working the third shift. She noticed the girl immediately. Something about the girl’s manner was not right. Dean handed her crayons and a promotional mask from the movie Madagascar, the kind of item the restaurant gave to young visitors. The girl did not react the way most would.
She was quiet and contained in a way that did not match her surroundings. Customers in the restaurant began to notice her, too. She looked familiar. She looked like the girl on the billboards and posters and news broadcasts that had been running across northern Idaho for the past seven weeks. A customer said something quietly. Then another.
Several people called 911 from inside the restaurant. Amber Dean understood what she needed to do. She needed to keep the man with the girl from leaving before police arrived. She began working through the dessert menu with the girl as slowly as she could manage. She went through every possible milkshake combination available. The girl chose vanilla.
Dean went to prepare it as slowly as a vanilla milkshake had ever been made in the history of that restaurant. The man asked why the milkshake was taking so long. Dean deflected. Police arrived with their lights off. Three officers entered the restaurant. The man was taken into custody without resistance. He gave his name.
He was Joseph Edward Duncan III, 42 years old, a federal fugitive from Fargo, North Dakota, wanted on a warrant for failing to appear in Becker County, Minnesota. Shasta Groene was at the table. She told Dean her name. She said Shasta Groene and started crying. Dean picked her, held her, and hugged her. Shasta was taken to Kootenai Medical Center, where she was examined and interviewed by detectives.
Word spread quickly through the community that she had been found. Dozens of people, families, young ones, people who had never met the Groenes, drove to the medical center and left gifts, cards, and balloons outside. Detective Brad Maskell arrived at the restaurant after the arrest. He had been working the case since the night of his 50th birthday.
Every detail she provided matched the physical evidence already collected at the Frontage Road crime scene. She told investigators that after the killings, Duncan had loaded her and Dylan into his red Jeep and driven them away from Wolf Lodge Bay. She said they had traveled to Montana to a remote campsite in the mountains.
She described the area as best she could and confirmed that Duncan had shown her the location on a map. Based on what she told them, investigators began searching the Lolo National Forest in western Montana near the town of St. Regis. They found the campsite. On July 4th, 2005, Sheriff’s Captain Ben Wolfinger held a press conference and announced that human remains had been found at the location.
The remains had been sent to the FBI laboratory in Quantico, Virginia for DNA analysis. On Sunday, July 10th, Wolfinger held another press conference. It lasted less than 1 minute. “According to the FBI lab in Quantico, Virginia, the remains found last week in Montana have been positively identified as Dylan Groene,” he said.
He took no questions. The hope that Dylan might have been found alive, as Shasta had been, ended in that moment. Investigators recovered additional evidence at the Montana campsite. They found a wire noose. They found items belonging to the two young ones. They found physical evidence connecting Duncan directly to the location.
They also recovered the video camcorder from the red Jeep Grand Cherokee, along with its recorded tapes. The footage was deeply disturbing. It showed Dylan subjected to sustained physical and verbal abuse by Duncan over an extended period. In one recorded segment, Duncan could be heard shouting at a restrained Dylan, “The devil is here, boy.
The devil himself. The devil likes to watch children suffer and cry.” The tapes were documented as evidence and secured. From the Jeep, investigators also recovered Duncan’s laptop computer with a Blues Brothers sticker on the lid bearing the phrase, “I’m on a mission from God.” They recovered a GPS unit with waypoints marking locations Duncan had identified during his drive west from Fargo.
The GPS data traced his entire route from North Dakota through Missouri, across the mountain states, and into Idaho. They found McKenzie’s wallet inside the vehicle. They found a jacket with blood stains on the passenger seat. It was sent immediately to the FBI laboratory for DNA analysis alongside the other physical evidence recovered from the campsite and the vehicle.
They also found letters, handwritten notes from Dylan and Shasta written to their father Steve Groene during the weeks of captivity. The letters had never been sent. They had been kept inside the Jeep throughout. From Dylan, “This is Dylan. We are still alive. We are okay.” From Shasta, “Dear Dad, I have good news. We’re coming home soon.
” Steve Groene was contacted by investigators. He had not received any letters from his children during the 7 weeks they were missing. He had not known they had written to him. The notes had sat inside the Jeep the entire time, folded and undelivered while he waited at home with no word from either of them. From the moment of his arrest, Joseph Duncan did not deny what he had done.
The physical evidence made denial pointless, and Shasta’s testimony alone placed him at the scene on the night of May 15th. But investigators did not yet know how far back his crimes extended. FBI agents conducted a lengthy interview with Duncan at the Kootenai County Jail on July 19th, 2005.
The session lasted more than 3 hours. During it, Duncan spoke about crimes he had committed before arriving in Idaho. Among the things he disclosed was the murder of Anthony Martinez in Beaumont, California in April 1997. He described the crime. He named the location. He said the killing had been his revenge against society for sending him back to prison on a parole violation.
When FBI agents made contact with Riverside County authorities in California and mentioned the name Anthony Martinez, investigators there immediately pulled the cold case file. The partial fingerprint recovered from the duct tape used to bind Anthony’s body had been sitting in that file for eight years.
Investigators flew to Idaho and fingerprinted Duncan. They submitted the print for comparison. The results came back on August 1st, 2005. The partial fingerprint on the duct tape from Anthony Martinez’s body matched Joseph Edward Duncan III. The case that had been cold for eight years was solved. Anthony’s family was notified. In the months that followed Duncan’s arrest, the FBI also reviewed his role in the Seattle area during his first parole period.
In January 2007, the US Attorney’s Office filed court documents confirming that Duncan had confessed to two additional murders. He had told agents that he killed Sammy Jo White and Carmen Tubbs in Seattle in July 1996. The two girls had been taken from the Crest Motel and their skeletal remains had been found in Bothell 17 months later.
FBI Special Agent Mike Socka testified during the federal sentencing trial that Duncan had killed the two girls by striking them in the head with a crowbar. King County authorities in Seattle were more cautious. A spokesperson acknowledged that Duncan had given agents details about the crimes but said the investigation remained open.
No charges were ever filed in the Seattle killings. Meanwhile, in Idaho, Duncan was formally charged in state court on July 13th, 2005. Three counts of first-degree murder and three counts of first-degree kidnapping for the deaths of Brenda Groen, Slade Groen, and Mark McKenzie. The families of the victims filed a civil lawsuit against Becker County, Minnesota, alleging negligence in setting inadequate bail and failing to communicate Duncan’s risk classification to the court.
The lawsuit was dismissed on jurisdictional grounds. From the time of his arrest, Duncan cooperated fully. He repeatedly told investigators and prosecutors that he wanted to plead guilty to everything. His public defender worked to manage the legal structure of the proceedings, but Duncan consistently pushed toward admission rather than defense.
What was becoming clear through the emerging evidence was that Duncan had planned the crimes with a precision that was difficult to comprehend. The GPS waypoints, the night vision goggles purchased weeks in advance, the stolen plates, the camcorder, the encrypted journal. He had been building toward something destructive over many weeks and had done so with deliberate method.
He was 42 years old. He had spent the majority of his adult life in prison. He had been warned, evaluated, classified, and released. He had a blog, a dean’s list record, a social network, and a university registration, and none of it had meant anything. The weeks following Duncan’s arrest in the Denny’s parking lot brought a series of formal legal steps that moved the case from its opening phase toward prosecution.
On July 13th, 2005, Duncan made his first court appearance in Kootenai County, where he was formally charged with three counts of first-degree murder and three counts of first-degree kidnapping. He appeared via video link from the county jail. He was unshaven and wore a yellow jumpsuit.
He said little during the hearing, acknowledging that he understood the charges, and asking whether he could consult his attorney. He appeared to be crying. Bail was denied on the kidnapping counts. A $2 million bail was set on a fugitive warrant for the outstanding Minnesota charges. The state charges relating to the two surviving young ones, Shasta’s abduction, and what had happened to Dylan were transferred to federal court.
Duncan had transported them across state lines for the purpose of sexual exploitation, making the crimes federal offenses under kidnapping statutes. The state and federal prosecutions would run in parallel. In October 2006, Duncan appeared in Kootenai County Court and entered a guilty plea to the state charges.
Three counts of first-degree murder and three counts of first-degree kidnapping for the deaths of Brenda Groene, Slade Groene, and Mark McKenzie. The state sentencing was deferred while the federal prosecution proceeded. In December 2007, Duncan appeared in federal court and entered a guilty plea on 10 counts. Three carried a potential death penalty, kidnapping resulting in death, sexual exploitation resulting in death, and using a firearm during a crime of violence resulting in death.
The remaining seven counts addressed the kidnapping and abuse of both young ones. A jury was impaneled solely to decide the sentence. Before the sentencing phase began, Duncan made a request that changed the shape of the proceedings. He asked the court for permission to dismiss his defense attorneys and represent himself.
His legal team, which included prominent capital defense attorney Judy Clarke, alongside Mark Larranaga and Thomas Monaghan, opposed the move. The court ordered a series of mental health evaluations to determine whether Duncan was competent to represent himself. US District Judge Edward Lodge reviewed the evaluations and ruled that Duncan was competent.
He granted the request. Clarke, Larranaga, and Monaghan remained in the courtroom as standby counsel, but were barred from actively representing him. When Judge Lodge told Duncan he would receive no special assistance from the bench and would be held to the same standards as any other attorney, Duncan replied, “I’m not a perfect person and I make mistakes sometime.
My only reservation is that I’m a human being.” The sentencing trial began in August 2008 in Boise. The courtroom held members of the victims’ families, law enforcement officers and the press. Prosecutors called approximately 90 witnesses over 5 days. The evidence they presented included GPS data from the stolen Jeep, financial records, a sawed-off shotgun recovered from the vehicle, the video recordings made by Duncan at the campsite, his blog entries, photographs and both videotaped and audiotaped statements from Shasta made
at the time of her rescue. When the audio recording of Shasta’s first moments with police at the Denny’s was played in court, the room went silent. In the recording, an officer asked her where her brother was. “In heaven,” she said. Then she began to cry. After a pause, she added, “There may be evidence down in the Lolo Forest because that’s where we were.
” When asked later why Duncan had brought her back to Coeur d’Alene, her answer was quiet. “He was going to take me home,” she said. “He said he was going to change his mind because I taught him how to love.” The federal sentencing trial continued through August 2008. Prosecutors brought witnesses to the stand one after another.
Family members of the victims testified, law enforcement officers testified, forensic experts testified. Jurors were shown video recordings Duncan had made at the Montana campsite. They were shown the wire news recovered from the location. They saw the physical remains collected from the campsite. Counseling was made available to jurors throughout the trial and the court later confirmed that support had been offered after the proceedings concluded.
The jury foreman later described being permanently affected by the evidence he had seen. Other jurors continued to meet with one another in the years following the trial, gathering to process the weight of what they had witnessed in that courtroom. During the sentencing trial, Shasta’s videotape testimony from 2005 was shown to jurors.
She described the night Duncan entered the house. She described the weeks at the campsite. She described the threats he made throughout the captivity. She described him showing her the hammer and telling her what he had used it for. She described what happened to her brother. What took place on the day Duncan killed Dylan at the campsite emerged in testimony.
According to Shasta, Duncan fired a shotgun at close range, striking Dylan in the abdomen. The wound was severe. A forensic pediatrician named Dr. Sharon Cooper testified that the injury Shasta described was consistent with a potentially survivable wound if immediate medical treatment had been provided.
Duncan was at a remote campsite hours from any hospital. He made no effort to seek help. He placed the shotgun against Dylan’s head and fired a second time. Dylan died. Duncan set fire to his body at the campsite afterward. He kept Shasta there for several more days. Then he drove back toward Idaho with her. The night before the rescue, Duncan told Shasta he was planning to take her to North Dakota to meet his family.
Throughout the captivity, Shasta had managed her own behavior in ways designed to stay alive. She had worked to gain his trust. She had told him what she believed he wanted to hear. She had, as Detective Brad Maskell later put it, fully orchestrated her own rescue. At the sentencing trial, Duncan stood before the jury to deliver his closing argument.
He confirmed in his own words the substance of everything the prosecution had argued. He told the jury, “You people really don’t have any clue yet of the true heinousness of what I’ve done.” He said his plan had extended far beyond the growing of family. He named the types of targets he had mapped out, daycare facilities, parking lots, campgrounds, private homes.
“I was not searching for a young person to take,” he said. “I was on a rampage. My intention was to continue until I was killed.” He spoke about his motivations in terms of revenge. “Revenge was certainly putting it lightly,” he told the jury. “I was on a rampage. I hated myself, and I hated you.
I hated everything that you represent. I hated the system. I knew the best way to hurt you was the same way that I was hurt. The system took my heart, and it took my innocence. And that’s what my intention was, to do the same to it.” He sat down. The jury deliberated for 3 hours. The jury returned its verdict on August 27th, 2008. All eight men and four women voted unanimously to find Joseph Duncan eligible for the death penalty on all three counts: kidnapping resulting in death, sexual exploitation resulting in death, and using a firearm during a crime of
violence resulting in death. The eligibility phase was followed immediately by the penalty phase, in which the same jury would decide whether Duncan should be executed or sentenced to life in prison without the possibility of parole. Prosecutor Tracy Welland delivered the closing argument for the government during the penalty phase.
“This defendant is dangerous,” she told the jury. “He is a predator who takes pride in his work. He earned this day. His actions call out for the death penalty.” Duncan had no closing argument for the penalty phase. He looked at Judge Lodge and said simply, “I have no argument.” The jury returned the death sentence on all three counts. Judge Edward Lodge sentenced Duncan to death in accordance with the jury’s verdict.
He also sentenced Duncan to three additional federal life terms, one for kidnapping Shasta, one for the offense against Shasta, and one for the offense against Dylan. Standing in the courtroom, Lodge addressed Duncan directly. “By any stretch of the imagination, your rampage exceeded the bounds of human understanding,” he said.
“These crimes were unfathomable, cruel, and sadistic.” Steve Groene was in the courtroom when the verdicts were announced. He sat with his eyes narrowed, blinking steadily, making no visible reaction as each count was read. When the proceedings ended, he found US Attorney Tom Moss. Using the electronic voice box that throat cancer had left him with, he said, “I feel much better now.
” Two weeks later, on September 15th, 2008, Duncan appeared in Idaho state court for sentencing on his 2006 guilty plea to the three murders at the Groene house. He received three life sentences without the possibility of parole for the killings of Brenda Groene, Slade Groene, and Mark McKenzie. That arrangement had been reached in part to spare Shasta from having to testify in open court about the murders of her family.
The federal and state sentences were combined into a total package. Three death sentences and 12 life sentences, all without the possibility of parole. Duncan was transferred to the United States Penitentiary in Terre Haute, Indiana, where the federal government housed its death row inmates. He arrived at the facility and was processed onto death row.
He immediately moved to waive his right to appeal. His attorneys opposed the waiver. They argued that Duncan had not fully understood his legal situation and that the waiver should not be permitted. Judge Lodge reviewed the competency question, relied on two extensive psychological evaluations already conducted, and found Duncan competent to make the decision.
He allowed the waiver to stand. An execution date was set. Then the 9th Circuit Court of Appeals intervened. Duncan’s attorneys argued that Lodge should have held an open hearing with witnesses and cross-examination before accepting the waiver, rather than relying on sealed evaluations. The 9th Circuit agreed and ordered a new hearing on the competency question.
In early 2013, Judge Lodge held a 23-day retrospective competency hearing. Psychologists testified on both sides of the question. Duncan’s recorded jailhouse interviews with FBI agents, totaling 24 hours of recordings made after his sentencing, were reviewed as evidence. The recordings covered his reasons for waving the appeal, his understanding of his legal situation, and his state of mind at the relevant times.
In December 2013, Lodge issued a detailed written order. He found that Duncan had been mentally competent when he waived his right to appeal. Duncan’s attorneys took the finding to the 9th Circuit Court of Appeals. In 2015, the 9th Circuit affirmed Lodge’s ruling. The competency determination stood.
In 2016, the attorneys petitioned the United States Supreme Court to hear the case. The Supreme Court declined. The competency challenge had run out of legal avenues. In 2017, Duncan’s attorneys filed a motion to set aside his conviction and death sentence, arguing ineffective assistance of counsel and related claims. Judge Lodge reviewed the motion and issued an order denying it on March 22nd, 2019.
Every avenue the legal system offered for continued challenge had been explored and closed. While these proceedings moved through the courts in Idaho, a parallel case was resolved in California. Duncan had confessed to the 1997 murder of Anthony Martinez during his July 2005 interview.
Riverside County fingerprint examiners had confirmed the partial print on the duct tape from Anthony’s body matched Duncan. California prosecutors charged Duncan with first-degree murder with special circumstances. On March 15th, 2011, Duncan appeared in a courtroom in Indio, California and entered a guilty plea of first-degree murder in the death of Anthony Martinez.
The plea agreement carried a mandatory sentence of life in prison without the possibility of parole. As part of the arrangement, Riverside County prosecutors agreed not to seek the death penalty in California, deferring to the federal death sentences already in place. District Attorney Paul Zellerbach explained the decision directly.
The federal system will kill him long before the state of California would have seriously considered it. Anthony Martinez’s family had been consulted before the plea was offered. They had waited since 1997. The 2005 fingerprint confirmation had told them who had taken their son. The 2011 guilty plea closed the legal chapter on Anthony’s case.
Back at Terre Haute, Duncan wrote his thoughts by hand and mailed them to an outside blogger who published them online under the title Fifth Nail Revelations. The entries were religious in tone at first, full of biblical references and parables. Then the blog shifted. He wrote about sex offender laws. He referred in the third person to what he described as the experience of a very good friend who had killed multiple young people during a parole period.
A friend who by every detail he provided was himself. Law enforcement monitored the blog. No additional charges resulted from its contents. In November 2020, Bureau of Prisons medical staff completed a health evaluation. They determined Duncan’s life expectancy to be between 6 and 12 months. He had been diagnosed with stage four brain cancer.
Court documents later confirmed that medical staff discussed end-of-life preparations with him at that time. Duncan declined chemotherapy. He declined radiation treatment. He accepted the prognosis without pursuing the treatments that might have extended his life. Joseph Edward Duncan III died on March 28th, 2021 at a hospital near the United States Penitentiary in Terre Haute, Indiana. He was 58 years old.
The stage four brain cancer diagnosed in late 2020 had progressed without treatment and he died before the federal government was able to carry out his execution. The United States Attorney’s Office for the District of Idaho issued a formal statement that morning. “This crime was horrendous and its impact on the families, the community, the jurors, court staff, our litigation team, and law enforcement were far-reaching.
” said acting US Attorney Rafael M. Gonzales, Jr. “While his death will not bring back the lives cut so tragically short or remove the indelible memories of his unspeakable acts, perhaps death will now allow space for some degree of healing, peace, and closure.” Assistant US Attorney Traci Wieland, who had prosecuted the federal case and described it as the only federal death penalty case in Idaho’s history, spoke briefly.
“His crimes were all publicly acknowledged and reviewed by a judge or jury. He was held accountable.” The reaction from the families of his victims was immediate. Diana Martinez, the mother of Anthony Martinez, released a statement. “The sun is brighter today and my soul is lighter,” she wrote. “The world is a more beautiful place without the evil that is Joseph Duncan.
God chose to make his end a long suffering and I believe that is fitting. The horror of his thoughts consumed him.” Shasta Groene issued her own written statement. “For so long I have been struggling with hate towards that man,” she wrote. “Today, I woke up feeling like my soul was finally free. I hope other people affected by Joseph Duncan were able to wake up feeling the same way.
” The Kootenai County Sheriff’s Office released a statement. “In May of 2005, the Groene family of Kootenai County, living in the Wolf Lodge Bay area, was brutally victimized by a serial killer passing through our community. The family was stalked, attacked, and tortured. It was one of the worst tragedies Idaho has ever seen.
” The jurors who had sentenced Duncan to death in 2008 responded publicly in a collective statement. “It was very frustrating to find him guilty and give him a death sentence and watch him stay alive for the next 12 to 13 years and to die a natural death,” they wrote. “Something’s wrong with the laws.” Former juror Tommy Watkins said, “I had no idea.
” He and other jury members had remained in contact with one another since the trial, meeting periodically to process what they had experienced in that courtroom. They described the footage and physical evidence as things that had never left them. “Then, when they said he was dead, I was glad,” said another juror.
“I was relieved. Shasta deserves not to have to think about him.” Retired detective Brad Maskell, who had spent 7 weeks working 17-hour days looking for Dylan and Shasta and who had taken Duncan into custody at the Denny’s in the early morning hours of July 2nd, 2005, received the news at home. He had retired from the Kootenai County Sheriff’s Department in the years since the case.
He had carried it with him for 16 years. The FBI had reviewed unsolved missing persons cases nationwide following Duncan’s 2005 arrest. He was cleared as a suspect in some of those cases. In California and Washington, authorities maintained that sufficient evidence existed to believe he had committed additional murders in those states beyond those formally confirmed.
The final accounting acknowledged in court was seven murders. Brenda Groene, Slade Groene, Mark McKenzie, and Dylan Groene in Idaho, Anthony Martinez in California, and Sammy Jo White and Carmen Tubbs in Washington, though only the Idaho and California deaths resulted in formal convictions. The confirmed span of his criminal activity ran from 1978 to July 2nd, 2005.
