A 15-year-old girl walks a few short blocks to her grandparents house just like she has a hundred times before. She lets herself in. She’s alone. 4 hours later, her grandfather comes home from the grocery store, opens the front bedroom door, and finds her lying on the floor. She’s been stabbed. The knife broke inside her body.

And the man who did it just walks away into a small southern town where everybody knows everybody. For 35 years, that town turns on itself. Neighbors point fingers at a 13-year-old girl. They whisper about an old man who only did one thing wrong. He was the one who found the body. Meanwhile, the real killer lives two blocks away, goes to work every single day, and eventually dies of old age in California, never once hearing his name spoken as a suspect.

This is the story of how a broken knife blade, a strand of hair, and 35-year-old evidence sitting in a police vault finally caught a killer who was already in the ground. To understand how devastating this case became, you have to understand what kind of place Salsbury, North Carolina was in June of 1984.

This wasn’t a city where people locked their doors out of habit. It was a tightrooted Piedmont community. The kind of town where your grandfather’s name meant something on its own. Risa Don Trexler’s family was exactly that kind of family. Her maternal grandfather, Walter Walt Monroe, was a familiar face around town. Her paternal grandfather, James Pinky Trexler, was practically a local institution for years.

He ran a concession stand at Legion baseball games, the kind of job where, you know, three generations of every family that walks up to buy a hot dog. Her uncle, Richard Monroe, ran Richard’s Barbecue, a real established local business. This was not a family that existed on the margins of Salsbury. They were woven into it.

Risa herself was 15, living with her mother, Vicky Monroe Oaks, and her younger sister, 13-year-old Jodie Trexler. The family home sat near the intersection of Bringing Ferry Road and North Shaver Street. And just a short walk away at 714 North Shaver Street was her grandparents house. That house wasn’t just a place Risa visited on holidays.

It was practically an extension of her own home. She was there constantly. On Friday, June 15th, 1984, Risa walked over to her grandparents house like she always did. Nothing about that walk would have felt unusual to her. Her grandmother had a hair appointment. Her grandfather, Walt, had gone to run errands at a nearby grocery store.

For roughly four hours, Rhysa was alone inside that house. When Walt Monroe came home, he walked into a front bedroom and found his 15year-old granddaughter’s nude body lying face up on the floor. What he discovered in that room would set off one of the most painful unsolved mysteries in Rowan County history.

And it would take 35 years and a revolution in forensic science before anyone could finally explain what happened during those 4 hours. But before we get to how it was solved, we need to walk through exactly what the crime scene told investigators and just as importantly, what it didn’t tell them. The scene inside that front bedroom would end up holding almost every clue investigators needed to eventually catch her killer.

The problem wasn’t a lack of evidence. It was that in 1984, nobody yet had the tools to read what that evidence was actually saying. When police arrived at 714 North Shaver Street, the first thing they noticed was what was missing. There was no forced entry, no broken window, no damaged lock, no sign that anyone had fought their way into that house.

And yet inside everything pointed to a brutal violent struggle. Risa had beenly assaulted and stabbed repeatedly in the neck and upper chest. During the attack, the knife used against her, a steak knife, actually broke. The handle sheared clean off and the steel blade snapped off inside her body, lodging deep in her right shoulder.

The fatal wound was determined to be a deep thrust that completely severed her spinal cord, causing instant incapacitation. The official cause of death was recorded as exanguination and spinal trauma from multiple stab wounds. The manner of death, homicide. Here is what made this case even more unsettling for investigators at the time.

Nothing was stolen. Risa was still wearing her watch, her ring, and her bracelet. Whoever did this wasn’t there for money or valuables. That single detail eliminated robbery as a motive almost immediately. And it told police something far more disturbing. This was personal or at the very least predatory. But the crime scene also handed investigators physical evidence that would decades later become the entire key to solving the case.

A standardized kit was collected and it confirmed the presence of semen on Reese’s body. Investigators also recovered a foreign hair from the scene. One identified using the microscopic analysis techniques available in 1984 as belonging to an African-Amean individual. And of course, there was the broken blade itself, still lodged in her shoulder, later extracted during the autopsy.

In other words, the physical biological proof of who did this was sitting right there in that room in June of 1984. The problem wasn’t that the evidence didn’t exist. The problem was that the technology to read it hadn’t been invented yet. And almost immediately, that gap between what the evidence showed and what investigators believed started to create real damage, not just to the case, but to the people closest to Rhysa.

Because in the days that followed, there were witnesses, real specific witnesses describing a real specific person seen fleeing the area. But what happened to that information and who investigators chose to trust instead would end up haunting this case for the next three and a half decades. In the immediate aftermath of the murder, police canvased the neighborhood around North Shaver Street and they got answers.

Nine separate witnesses reported seeing a black male in the vicinity of the crime around the time of the murder. Five of those witnesses specifically said they saw him running. That is not a vague tip. That is nine independent people in a small town describing the same kind of figure in the same general location at the same critical window of time.

And yet that lead didn’t go where you’d expect. Sometime in the mid 1980s, the FBI’s behavioral science unit produced a psychological profile of the likely offender. That profile described a white male somewhere between 18 and 24 years old, someone who likely knew the victim in a non-personal way, an acquaintance level connection rather than a stranger.

It was a theory built on behavioral patterns from other cases, not on the physical witness statements collected just days after the murder. And here’s the devastating part. That profile didn’t just fail to help. It actively worked against the case. Investigators began treating the FBI’s psychological theory as more credible than the eyewitness accounts already sitting in their files.

The witness reports of a black male fleeing the scene were pushed aside, treated as secondary leads instead of the central lead they should have been. This single decision, trusting a behavioral profile over nine eyewitnesses, created a blind spot that would last for decades. Because if investigators had followed the witness statements as their primary lead in 1984, there was a man working just two blocks from that house who might have come under scrutiny almost immediately.

Instead, he never did. And it wasn’t just that this man wasn’t investigated. At one point, police actually had physical contact with evidence connected to him. They just didn’t know what they were looking at yet because the science of 1984 wasn’t capable of telling them. Early in the investigation, police seized a knife connected to an individual cataloged in their records only as C. Blair.

Think about that for a moment. Investigators were at some point in 1984 physically holding a piece of evidence tied to the man who would 35 years later be confirmed as Reese’s killer. They tested that knife using the cerological methods available at the time. Essentially basic chemical and visual testing designed to detect blood.

The result came back negative. No trace blood detected on the blade. And with that single negative test, the knife and its owner were eliminated from active focus. Today, forensic scientists understand something that 1984 era simply couldn’t account for. Killers clean their weapons, and even when they don’t, early luminol and protein-based assays lack the sensitivity to pick up microscopic, degraded, or diluted biological traces that a modern crime lab would catch instantly.

A clean testing knife in 1984 doesn’t mean an innocent knife. It means the test wasn’t sensitive enough to see the truth. So, here’s the picture forming in 1984. Nine witnesses describing a black male fleeing the scene, overridden by an FBI profile describing a young white acquaintance. A knife connected to a man named Blair, cleared by a test too primitive to detect what modern science would later confirm.

Two separate moments where the truth was right there, and two separate moments where it slipped through investigators hands. With no arrest, no named suspect, and the trail going cold, the case did something that so many unsolved murders in small towns eventually do. It stopped being a mystery about a killer, and it started becoming a mystery the town pointed inward at itself.

Because when a community can’t accept that a murder has simply gone unsolved, it starts looking for someone to blame close to home. And in Salsbury, the people who paid the price for that were the two people who had already lost the most. For over three decades, in the absence of an arrest, rumor filled the vacuum where facts should have been.

Jod Trexler, Risa’s younger sister, only 13 years old at the time of the murder, became a target of persistent local gossip. People speculated without any evidence that Jod had killed her own sister during some kind of domestic dispute. Neighbors pointed to unverified claims about sibling rivalry. Some people went as far as scrutinizing how a grieving 13-year-old girl behaved at her sister’s own funeral, treating a child’s trauma response as if it were evidence of guilt.

Her grandfather, Walt Monroe, faced his own version of that same cruelty. His only real crime was being the one who walked into that bedroom and found her. But in a town desperate for an explanation, even that became suspicious to some people. The man who discovered his granddaughter’s body found himself at times treated like a suspect simply because he was the one who was there.

Living inside that kind of suspicion for years for decades takes an enormous psychological toll. Jod Trexler, who by this point had grown up, gotten married, and became Jodie Trexler Lair, carried this weight into adulthood. And by 2018, she decided she wasn’t willing to carry it silently anymore. She reached out to the producers of the Dr. Phil show.

What happened next didn’t just clear her name in front of a national television audience. It set off a chain reaction that would pull 35year-old evidence out of a police vault and put it back under a microscope. Literally. On April 9th, 2018, an episode of the Dr. Phil show aired with the title Cold Case.

I didn’t murder my 15-year-old sister. Jodi Trexler Leairard appeared on national television and agreed to undergo a polygraph examination administered by Jack Treearco, a former FBI polygraph examiner. The result, Jod was found to be truthful when she denied any involvement in her sister’s death. Now, a polygraph on a talk show doesn’t carry legal weight in a courtroom, but it carried something arguably more important in this specific moment.

Public attention. The broadcast exposed on a national stage the exact kind of small town stigma Jod had been living under for over three decades. It reframed the story for a massive audience. Not which family member did this, but why has no one ever been held accountable for this at all? That national spotlight reached the desk of Detective Sergeant Travis Schulenberger, who by this point had taken over management of the cold case file at the Salsbury Police Department.

And in June 2018, just two months after that broadcast, Schulenberger made a decision that would ultimately crack the case wide open. He pulled the preserved 1984 assault kit swabs out of cold storage and submitted them to the North Carolina State Crime Lab for modern STR DNA extraction. Understand what this moment represents.

Police departments are typically skeptical of talk show appearances. They’re not usually treated as credible investigative triggers. But in this case, the public pressure and renewed attention generated by Jod’s appearance directly led to the evidence being retested using technology that simply didn’t exist in 1984. It’s a rare concrete example of media tension functioning as a genuine catalyst for reopening a cold case rather than just generating noise.

And what that retesting revealed would set the entire final chapter of this case into motion. Because for the first time in 34 years, scientists were able to isolate something clean, complete, and unmistakably specific from that evidence, a full male DNA profile. The only question left was whether it would match anyone.

By June 2018, DNA science had advanced light years beyond where it stood in 1984. Using modern short tandem repeat or STR extraction techniques, technicians at the North Carolina State Crime Lab successfully isolated a clean single source male DNA profile from the preserved sperm swabs collected during Reese’s original 1984 kit.

This was a massive technical achievement in itself. Preserving biological evidence for over three decades without degradation is not a given. It requires consistent, careful cold storage maintained across changes in detectives, changes in department leadership, changes in facilities. But the Salsbury Police Department had done exactly that. The evidence had survived.

With a clean profile finally in hand, investigators did what modern forensic protocol calls for. They uploaded it to Kodas, the combined DNA index system, the national database used to match crime scene DNA against the profiles of known previously convicted offenders across the country. No hit came back. That result might sound discouraging, but it actually told investigators something important.

Whoever committed this crime either had never been convicted of a crime requiring DNA submission to Cotus or he simply wasn’t in the system for some other reason. A dead end in Cotus didn’t mean the DNA was useless. It meant investigators needed a completely different kind of database. One that didn’t rely on criminal history at all, but on family trees.

That’s when the case moved into the hands of a private forensic science company that had in just the last few years revolutionized how cold cases get solved across the entire country. In March of 2019, that DNA extract was sent to a lab in Restston, Virginia, a company that doesn’t search for criminals directly. It searches for their relatives.

The extract containing the male DNA profile was forwarded to Parabon Nanolabs, a forensic science company that applies a technique called investigative genetic genealogy, sometimes shortened to IGG, to cold cases where a direct cotus match has failed. Here is how the process actually works, and it’s genuinely fascinating. Instead of running a standard STR comparison, which only checks for direct matches to people already in criminal databases, Parabon performs highdensity snip genotyping, essentially reading hundreds of thousands of single points

across the suspect’s entire genome. The same kind of deep genetic mapping used by consumer ancestry services. That SNP profile was then uploaded to Gene Match, a public open-source genealogy database where users voluntarily upload their own genetic data, often just to research their family history and separately consent to allow law enforcement matching.

Lead genetic genealogologist CC Moore and her team began comparing shared DNA segments measured in centmorggans between the unknown suspects profile and the people already in that database. The matches that came back weren’t close relatives. Nobody’s brother, nobody’s parent. Instead, the team identified a network of second, third, and fourth cousins.

Distant relatives who had no idea their own genetic data was about to help crack a 35-year-old murder case. From there, the genealogologist did painstaking manual reconstruction work, cross-referencing public family trees, historical census records, marriage certificates, military service records, and published obituaries, building out entire descendency trees back to shared ancestral couples multiple generations removed from anyone alive today.

But a family tree alone doesn’t name a killer. To narrow that sprawling web of relatives down to a single person, the team applied a set of process of elimination filters. The suspect had to be in the right geographic location in June 1984, within a plausible age range, male, and consistent with the biological racial characteristics indicated by the earlier hair analysis from the crime scene.

When all of those filters were applied to that reconstructed family tree, it converged, narrowing down through generations of cousins, uncles, and branching family lines onto a single name. On April 8th, 2019, Parabon Nanolabs delivered a formal report to Salsbury investigators identifying their candidate, Curtis Edward Blair. But there was an enormous problem standing between this name and a courtroom.

Curtis Edward Blair had been dead for 15 years, and you cannot put a dead man on trial. What investigators needed next wasn’t a suspect interview. It was a body. Before we get to the exumation, it’s worth sitting with exactly who Curtis Edward Blair was because his profile lines up almost eerily with the evidence that had been sitting in police files since 1984.

Blair was a black male in his 40s at the time of the murder in June 1984. In 1984, he was employed at a Fredo Laid distribution facility located just two blocks from 714 North Shaver Street, the exact house where Risa was killed. That’s not a city-wide coincidence. That’s a man who worked day in and day out within easy walking distance of the crime scene, giving him intimate familiarity with the neighborhood and creating a completely plausible opportunistic window during his work shift or his commute.

Blair also had a documented criminal history in North Carolina, a prior conviction for assault with a deadly weapon for which he had served time in state prison. And remember that knife seized early in the 1984 investigation connected to a name recorded only as C. Blair, the one that tested negative for blood using outdated corological methods.

That detail connects directly back to this same man. Crucially, investigators found absolutely no personal, family, or business relationship between Curtis Blair and Rhysa Trexler, or the Monroe family. This wasn’t a domestic dispute, an ex-boyfriend or a family friend. Every scrap of evidence points to exactly what the crime scene suggested from day one, an opportunistic, predatory attack by someone who lived and worked nearby, but who had no personal connection to Resa at all.

At some point after the murder, Blair left North Carolina entirely and relocated to San Diego County, California, where he lived for the next two decades. He died there on August 6th, 2004 at around 60 years old. His remains were shipped back across the country to Rowan County and interurred at Memorial Park Cemetery in Salsbury, the very town where, unbeknownst to everyone around him, he had left behind an unsolved murder 15 years earlier.

He was buried less than a mile potentially from the family he had shattered and he took his secret with him. Except DNA doesn’t die. And in the summer of 2019, investigators went to go get it. Getting a DNA sample from a deceased man isn’t as simple as swabbing a cheek. It requires a court order, a cemetery, and a funeral home willing to reopen a grave that had already been sealed for 15 years.

Because Curtis Edward Blair had already died in 2004, traditional criminal proceedings, an arrest, an indictment, a grand jury, a trial, were completely off the table. You cannot prosecute a dead man. But the Rowan County District Attorney’s Office still needed one final irrefutable piece of proof before this case could be considered scientifically closed.

A direct DNA comparison between Blair himself and the sperm profile recovered from the crime scene in 1984. That meant getting a court order. The DA’s office filed a formal petition for exumation in North Carolina State Court, citing Parabon Nanolab’s genetic genealogy findings, combined with the corroborating circumstantial detail of Blair’s 1984 employment just two blocks from the crime scene as probable cause to exume his remains.

The court approved the petition. A judicial order was served on Memorial Park Cemetery and the exumation was carried out under legal and medical supervision. Larly Funeral Home provided the facilities needed to carefully collect bone and tissue samples from Blair’s remains while still ensuring he was respectfully reentered afterward.

Those tissue and bone samples were sent to the North Carolina State Crime Lab. And on August 6, 2019, 15 years to the day after Curtis Edward Blair had died in San Diego, scientists confirmed a definitive onetoone nuclear DNA match between his remains in the sperm profile recovered from Rhysa Trexler’s body 35 years earlier. There was no more ambiguity left.

No more competing theories. No more FBI profile pointing investigators in the wrong direction. The science had reached back across 35 years and named the man conclusively. All that remained was for the Salsbury Police Department to make it official in front of the family and in front of the entire town that had spent three and a half decades pointing fingers in the wrong direction.

On December 3rd, 2019, that announcement finally came. And for one family, it meant something far bigger than just closing a file. On Tuesday, December 3rd, 2019, the Salsbury Police Department held a joint press conference to formally announce the resolution of Rhysa Trexler’s murder. Police Chief Jerry Stokes confirmed the case was officially closed with the suspect’s identity conclusively established through DNA.

Detective Sergeant Travis Schulenberger walked the room through the full timeline, the 2018 retesting decision, the Parabon referral, and the exemation process that followed. North Carolina Attorney General Josh Stein also spoke at that press conference, emphasizing the transformative role DNA science had played in finally cracking a case that had outlived multiple generations of detectives.

And then he did something the Texler and Monroe families had waited 35 years to hear spoken publicly and officially. He formally exonerated Jodi Trexler Leair and alongside her the entire Monroe and Trexler family of any involvement whatsoever in Reese’s death. Jodie Trexler Lair and her mother Vicky Monroe Oaks were present.

After 35 years of sleepless nights and public suspicion, they said they could finally grieve peacefully. Think about the weight contained in that sentence. not we finally have justice in the traditional sense because there would be no trial, no verdict, no sentencing. Justice here looked different. It looked like a state attorney general standing at a podium and telling an entire community on the record that the family they had quietly blamed for 35 years had never had anything to do with it at all.

The real killer had been living two blocks away the whole time. He had gone to work every day at that Fredo plant. He had eventually packed up and moved 3,000 mi away to California, built a life, grown old, and died without ever once being publicly connected to Risa Trexler’s murder while he was alive. With the science settled and the family exonerated, what remains is arguably the most important part of this story.

Not the who, but the why it took 35 years. And that answer says something uncomfortable about how investigations can go wrong even when nobody involved is acting in bad faith. Strip away the emotion for a moment and look at this case purely as a study in investigative failure points because there were exactly two moments in 1984 where this case could have been solved almost immediately and both of them slipped away due to the limitations of that era.

The first failure point was psychological, not technical. Nine eyewitnesses described a black male in the immediate area. Five of them specifically saw him running. That’s about as strong as an eyewitness lead gets in the first hours of a murder investigation. But an FBI behavioral profile built on statistical patterns from other cases, not on evidence from this one, pointed investigators toward a young white male acquaintance instead.

Investigators trusted the theoretical profile over the physical witness accounts, and that single choice buried the correct lead for over three decades. The second failure point was purely technological. Police had already seized a knife connected to a man named C. Blair in 1984. They tested it using the cerological blood detection methods available at the time.

It came back clean, but we now understand that early luminol and protein-based testing lacked the sensitivity to catch microscopic or degraded biological traces. Meaning a clean test in 1984 didn’t prove innocence. It just proved the technology of the era couldn’t see the truth yet. Two moments, two near misses. And in both cases, the actual physical evidence needed to identify Curtis Edward Blair was already sitting inside the Salsbury Police Department.

It just took 35 years, a national TV appearance, and a genetic genealogy revolution for anyone to finally read it correctly. Between 1984 and 2019, the North Carolina State Crime Lab processed the physical evidence in this case across 10 separate testing events, generating 14 formal forensic reports. 10 attempts, 14 reports.

And it took a private genealogy company cross-referencing distant cousins in an online database that didn’t even exist until years after most of those reports were written to finally close the gap. What makes the Risa Trexler case so haunting isn’t just the brutality of what happened to her on June 15th, 1984. It’s everything that happened after the 35 years where a killer lived, worked, and eventually died in peaceful anonymity while the family he devastated absorbed the suspicion that should have belonged to him. Jodie Trexler Leard was 13 years

old when her sister was murdered. And she spent the better part of her life living under a cloud of rumor for a crime she had absolutely nothing to do with. Her grandfather carried the burden of simply being the one who found the body. And an entire community organized itself around theories that DNA science would eventually prove were completely provably wrong.

In the end, it wasn’t a confession, a witness, or a courtroom trial that solved this case. It was a broken knife blade preserved in an evidence vault. A strand of hair, a kept in cold storage for 34 years, a national television polygraph that reignited public pressure, and a genealogologist tracing distant cousins through century old marriage certificates and obituaries until every branch of a family tree pointed to one man working two blocks from a teenage girl’s grandparents house.

Curtis Edward Blair never faced a jury. He never spent a single day answering for what he did, but he didn’t get away with it either because 35 years later, science reached into the ground and said his name anyway. If this is the first case you’ve seen where investigative genetic genealogy cracked open a decades old cold case, it is far from the only one.

This exact technique, the same SNP genotyping, the same g match cousin matching process that identified Curtis Edward Blair is the very method that finally caught the Golden State Killer after more than 40 years on the run. If you want to understand exactly how that breakthrough happened and how one company’s genealogy work is now quietly rewriting the ending of cold cases across the entire country, that video is right here.
