Missouri EXECUTE 18yrs old killer-He r@ped and drown mum and her Family- First execution since 1989
Missouri EXECUTE 18yrs old killer-He r@ped and drown mum and her Family- First execution since 1989
On January 31st, 2017, inside the Eastern Reception, Diagnostic and Corrections Center in Bonne Terre, Missouri, Mark Anthony Christeson lay strapped to a gurney. At 6:57 p.m., lethal injection began. He was 37 years old and had been convicted of the murder of Susan Jo Broock, a single mother who worked a factory job in St.
James, Missouri. He was also convicted of murdering her daughter, Adrienne, and her son, Kyle. Three people, one family, wiped out on a Sunday morning in February 1998 before the rest of Maries County had finished breakfast. He was 18 years old when he did it. He and his 17-year-old cousin walked to Susan’s house with shotguns.
They went in through the front. They bound the young ones’ wrists with shoelaces brought specifically for that purpose. Christeson forced Susan into her daughter’s bedroom at gunpoint. When they came back out, one of the young ones recognized the cousin and said his name aloud. That was the moment Christeson made his decision.
He told his cousin what needed to happen. Then he made it happen at a pond southeast of the house in the freezing Missouri winter with a bone knife and his bare hands. Afterward, the two of them loaded Susan’s stolen belongings into her Ford Bronco and drove west. They sold her television. They sold her VCR. They pawned the shotgun in Texas.
They made it all the way to Blythe, California, nearly 2,000 miles before a detective recognized them from a circulated photograph and put them in handcuffs 8 days after the murders. The case against Christeson was overwhelming. DNA evidence, ballistic evidence, physical evidence from the scene, and the first-hand testimony of the cousin who had been present for every moment and agreed to tell prosecutors exactly what happened.
The jury deliberated and returned guilty on all three counts of murder in the first degree. Death on all three counts. That should have been the end of the legal story. It was not even close to the end. Christeson’s appointed federal attorneys missed a critical filing deadline by 117 days and hid that mistake from him for nearly a decade.
As a result, no federal court ever reviewed his case on its merits. In 2014, the Supreme Court stopped his execution with hours to spare, but it was only a temporary intervention. The legal fight that followed lasted until the very night of his death. He was given new attorneys, denied the funding those attorneys needed, rushed through a compressed legal process, and executed on January 31st, 2017.
The first person put to death in Missouri since 1989 without any federal court ever evaluating the substance of his case. But to understand how an 18-year-old boy from a rural Missouri community, raised by a diagnosed pedophile, removed from his mother’s custody at 11, arrived at a pond on a February morning and did what he did to a family that had never harmed him.
We have to go back to the beginning. If you follow cases where the crime and the system that processed it both demand to be examined, where the full story is never what the headline suggested, subscribe to No Way Out. This is where true crime is taken apart completely, from the first breath to the last. Every detail, every layer, nothing left out.
In the rural heartland of Missouri, where small towns sit far apart and neighbors often know each other’s names, a boy named Mark Anthony Christeson came into the world in the late 1970s. He was born into a family already fractured before he could walk or speak. Mark grew up believing that a man named William Christeson was his father.
William was a difficult man, prone to violence, and the household he maintained with Linda Christeson, Mark’s mother, was one of constant conflict. The two fought regularly and with intensity. Missouri’s Division of Family Services received multiple reports about the home and intervened on several occasions, yet Mark remained in that environment for years.
There was no stability inside those walls. There was no peace. Linda Christeson struggled severely with her mental health. She was hospitalized multiple times for depression, and on at least one occasion, she was admitted following an attempted suicide. She leaned heavily on her older son, Billy, showing him favor and closeness that she never extended to Mark.
For reasons that were never fully explained to him, Mark felt his mother’s rejection in a deep and lasting way. He was the son she turned away from, the one who went without the warmth that Billy received. That absence left a wound that did not close. What Mark did not know for most of his early life was that William Christeson was not his biological father at all.
The man who lived in the house, who fought with his mother, whose name he carried, was not the man whose blood ran in him. William Christeson had a brother named Johnny. Linda Christeson, Mark’s mother, had been involved with Johnny. Not as a passing encounter, involved enough and for long enough that she became pregnant.
The child she carried was not William’s, it was Johnny’s. It was Mark. This meant that the man raising Mark as his son was in fact his uncle. And the man who was actually his biological father, Johnny Christeson, was living somewhere in the same extended family world known to Mark not as his father, but as his uncle.
The roles were completely reversed from what Mark had been led to believe, and the deception held for years. The circumstances of Mark’s conception were never openly addressed within the family and the truth was buried beneath a household that had far more pressing crises to manage. Johnny Christeson, for his part, was not a stabilizing presence either.
He, too, was institutionalized at various points in his life due to serious psychiatric disorders. Mark had inherited a bloodline tangled with mental illness on both sides, though no one in his young life was paying close enough attention to recognize what that might mean for his development. William Christeson was a diagnosed pedophile.
Court and institutional records documented accusations that he had molested multiple members of the family across the years he was present in their lives. The full extent of what happened under that roof, who was affected and in what ways, was never comprehensively investigated or adjudicated. What is documented is that sexual abuse of family members was occurring inside the household where Mark spent his earliest years.
He was living in an environment where that was part of the reality, whether or not any adult acknowledged it openly. By the time Mark reached school age, the damage was already measurable. He was placed in special education classes early in his schooling and remained in them throughout his education. Despite the extra support, he continued to receive failing grades.
Childhood IQ testing recorded scores in the mid 80s, placing him in the below average range. His performance on achievement tests was even lower, scores that placed him in the second and third percentile compared to other students his age. Between elementary school and junior high, something accelerated his decline.
In the third grade, Mark was functioning at a low average level. By seventh grade, he had fallen to the first percentile. Teachers and administrators noted the drop. No one conducted a thorough investigation into why it was happening. No comprehensive psychological evaluation was ordered. Mark Christeson grew up without a single reliable adult in his life.
The people who were supposed to protect him failed him. The systems that were supposed to intervene failed him, and the damage accumulated quietly year after year in a boy that no one was truly watching. When William Christeson died in 1990, Mark was around 11 years old, and with William gone, the state of Missouri finally acted, removing Mark from his mother’s custody entirely.
What came next was supposed to be better. It was not. He was placed with a relative named David Bolin. On paper, it was a placement within the family, a familiar face, a familiar name, a chance at some form of stability. In reality, it was a transfer from one damaged environment into another. David Bolin lived on a rural property outside Vichy, Missouri, a small community in Maries County in the south-central part of the state.
The land was dotted with trailers that Bolin rented out to various people, and the property served a dual purpose. It was both his income source and a kind of informal foster arrangement. Bolin took in children from within the extended family, collecting state funds for their care. The arrangement suited him financially.
Whether it suited the young people placed there was another matter entirely. The area around Bolin’s property had a reputation that locals knew well. People in the area referred to it informally as Bolin Hill, and the name carried weight. It was known as a place where violent altercations were common, where poverty ran deep, where drug use was regular, and where the rules that govern more ordered households simply did not apply.
Incest and sexual exploitation were part of the environment’s dark fabric. It was not hidden. It was known. And yet children continued to be placed there. Mark arrived at Bolin Hill as a boy of about 11, already carrying the damage of everything that had come before him. The rejection by his mother, the violence he had witnessed between his parents, the sexual abuse he had experienced in the family home, the head injuries, the academic failure.
He arrived already behind. He arrived already hurt. And the place he arrived at had no intention of healing any of it. According to accounts that would surface years later, David Bolin himself subjected Mark to sexual abuse. The same pattern that had defined the home Mark came from continued in the home he was sent to.
The cycle did not break. It extended. Mark ran away from Bolin’s property multiple times. He was not running toward anything specific. He had nowhere to go, no family member willing or able to take him in, no resources, no plan. He was running away from what was happening to him, trying to put distance between himself and a place that caused him harm.
But each time, he was returned. The state had placed him there, and the state’s mechanisms for monitoring what was actually happening on that property were insufficient. He kept going back. Years passed this way. Mark moved through adolescence at Bolin Hill, receiving no meaningful education, no therapy, no intervention.
He had long since stopped attending school in any functional capacity. The special education placements that had been arranged during his earlier years faded away. Around the time Mark entered his mid-teens, his cousin Jesse Carter also came to live at Bolin’s property. Carter was a year younger than Mark, and like Mark, he came from a family with its own set of difficulties.
The two were related through the extended Christeson family network, and being close in age, they fell into a natural companionship. They shared the same cramped, chaotic environment. They shared the same lack of supervision. They shared the same absence of structure, guidance, or anyone who gave serious attention to where their lives were heading.
By the time both were in their late teens, Bolin Hill had become the only world either of them knew. They had no jobs. They had no formal education to speak of. They had no plans for the future in any concrete sense. What they had was each other. A property that offered very little, and a restlessness that had nowhere productive to go.
Mark was 18 years old, and Jessie Carter was 17 when the events of early 1998 began to take shape. Half a mile away from the Bolin property, in a modest home along the rural road, a woman named Susan Broocke was raising her family. She knew the area the way lifelong residents know a place, deeply, quietly, with familiarity in every direction.
She had no reason to feel afraid of her neighbors. She had no reason to believe that the restlessness building on the property down the road had anything to do with her. She did not know the two teenagers living at Bolin Hill. But one of them knew who she was. Susan Joe Broocke was born on October 23rd, 1961 in Rolla, Missouri. She grew up in the Vichy area of Maries County, the kind of place where people stayed close to the ground they were raised on.
Where families put down roots and tended them. Susan was one of those people. She never moved far from where she began. She attended Belle High School, where she was, by any measure, a young woman of genuine substance. She graduated in 1980 as an honor student. She was involved in everything around her, a member of the band, a member of the choir, vice president of her class, a candidate for May Day Queen, active in the Future Homemakers of America, a participant in the Pep Club.
She threw herself into the life of her school with the kind of energy that comes from someone who genuinely enjoys being part of something. People noticed her. People liked her. After graduation, Susan built a life in the area she had always known. She found work in the production department at Talema Industries in St.
James, Missouri. Steady employment, honest work, the kind of job that anchors a life in a community. She was reliable. She showed up. She did what needed to be done. At some point, Susan entered into a relationship with a man named Christopher Broock, and together they had two children. A daughter, Adrian, born in March of 1985, and a son, Kyle, born in September of 1988.
The relationship with Christopher eventually ended, and Susan found herself a single mother in the rural Missouri community where she had spent her whole life. She had the support of her family, her parents, her siblings, and she had her job, and she had her two young ones, and that was what her life was built around.
Those who knew Susan described her in consistent terms. Her entire world revolved around Adrian and Kyle. Everything she did, she did with them in mind. Adrian was 12, a seventh grader at St. James Junior High who played volleyball, sang in the choir, played in the band, and had already begun thinking about becoming a veterinarian or a teacher.
She had written a poem in sixth grade with a line about love persisting even when fate is unfair. Words she put down without knowing they would one day carry a weight far beyond the moment she wrote them. Kyle was nine, energetic and soccer playing with a specific dream of becoming an army officer someday. The two were different in temperament, but deeply connected as siblings, sharing a home and a mother, and the steady rhythms of an ordinary family life in rural Missouri.
Their half-sister Harley, only five at the time, lived separately, but loved them in the way that only genuine family attachment produces. The home they shared was modest and warm. Susan kept it running with the kind of quiet discipline that single parents develop out of necessity, managing the household, getting the young ones to school, keeping things together.
She drove a Ford Bronco, a practical vehicle suited to the rural roads of Maries County, where the terrain and the weather demanded something sturdy. Her sister, Kay Hayes, lived close enough to stay in regular contact. The extended Southard family, Susan’s parents Joseph and Winifred, her brother Michael, and her sisters Joy and Barb, were a present and active part of Susan’s life.
Sunday dinners and family events were regular fixtures. The family was close. Susan and the young ones were expected, anticipated, missed when they didn’t show. In late January 1998, Susan was 36 years old. Her daughter Adrienne was approaching her 13th birthday in March. Her son Kyle had turned nine the previous September. The three of them were living their quiet life on the rural road near Vichy, going about the business of an ordinary week in the cold Missouri winter.
Susan had no reason to be afraid. She knew her neighbors. She knew her community. She was part of the fabric of Vichy in the way that only lifelong residents can be. The threats that existed in the world, the kind that came from strangers, from violence, from the darker impulses of people she had never wronged, those felt distant, abstract, the sort of thing that happened somewhere else.
Susan had no reason to be afraid. She knew her neighbors. She knew her community. She was part of the fabric of Vichy in the way that only lifelong residents can be. It was an ordinary life running at its ordinary pace. And the two young ones sharing that life with her, Adrian and Kyle, were living their own version of ordinary, each absorbed in the particular world of their age and their interests and their plans for what came next.
While Susan kept the house running and Adrian worked through her schoolwork and Kyle kicked his soccer ball around in whatever space the winter allowed, half a mile down the road at the Bolin property, things were moving in a different direction entirely. January 31st, 1998 was a Saturday. David Bolin was at home. The two young men on his property were going about the day the way they went about most days, without structure, without purpose, without anything pulling them in a particular direction.
But something had shifted between them in recent days. The talk about leaving had stopped being talked about. It was becoming something more specific, more deliberate. They were not just thinking about getting out anymore. They were planning it. The first problem was practical. They had no vehicle.
Without a vehicle, there was no leaving, not across the kind of distances they were thinking about, not out of Missouri, not anywhere that felt far enough from Bolin Hill to matter. They needed transportation. And they needed it in a way that did not require money they did not have. Mark knew exactly where to find one. Susan Brox’s Ford Bronco sat parked at her home half a mile away.
Mark had seen it. He knew the house, knew the road that led to it, knew the general rhythms of the property in the way that people who live close to each other in rural areas absorb details without necessarily seeking them out. The Bronco was not the only thing on Mark’s mind. Mark had also spoken about Susan Broock herself.
Had expressed a specific intention toward her that went beyond stealing her vehicle. The plan that was forming was not a simple car theft. It carried something darker inside it from the very beginning. Sunday morning, February 1st, they waited for Bolin to leave for work. When his vehicle pulled away from the property and the sound of it faded down the road, the two of them moved.
It was the window they had been waiting for. Mark and Jessie each picked up a 16-gauge shotgun. They walked out of the Bolin property and onto the rural road. It was February 1st, 1998. The Missouri winter was holding firm, cold, gray, quiet. The kind of morning where sound travels differently, where the world feels still in ways that have nothing to do with peace.
They moved along the road toward the Broock house. Half a mile is not a long walk, even in the cold. Within minutes, they were outside Susan’s home, standing at the edge of the property, looking at the house where a woman and her two young ones were beginning their Sunday morning.
They hid outside for a few moments, then they went in. Inside, Adrian and Kyle were sitting on the living room floor. The house was warm. The morning was ordinary. Nothing about it suggested what was about to happen. Carter moved first, pulling out the shoelaces he had brought from Bolin’s property for exactly this purpose. He began binding the wrists of the two young ones, tying them behind their backs with deliberate, prepared motion.
This was not an improvised detail. He had brought the shoelaces. He had planned to use them. Susan came in from the kitchen and stopped when she saw what was happening. Mark Christeson moved Susan Broock at gunpoint from the living room down the hallway and into her daughter Adrienne’s bedroom. He forced her onto the bed.
He sexually assaulted her. In the living room, Jesse Carter remained with the two young ones, their wrists bound with shoelaces. The house was quiet except for whatever sounds carried between rooms. The Sunday morning that had begun as an ordinary winter day had become something else entirely in the space of a few minutes.
When Mark came back into the living room, Adrienne looked up. She had been looking at the young man who had just entered, Jesse Carter. She recognized him. She knew his face from somewhere, perhaps from having seen him before in the area, in the way that people in small rural communities sometimes know each other without formal introduction.
She said his name. That was the moment everything shifted. Carter’s name, spoken aloud by a girl who could identify him, changed the calculation. Recognition meant witness. A witness meant exposure. The plan had already gone further than a simple car theft. Now it had a new and terrible weight to it.
Mark turned to Carter. He looked at Carter and said, “We’ve got to get rid of them.” Carter did not argue. He did not push back. He did not suggest another option. Whatever reasoning the 17-year-old might have offered in that moment went unspoken. The decision was made and it was made quickly. Susan and her two young ones were forced to their feet.
The stolen household items, the television, the VCR, and other belongings from the Broock home were loaded into Susan’s Ford Bronco. Then Susan and the young ones were forced into the vehicle at gunpoint. Mark took the wheel. Carter was in the vehicle as well. The Bronco pulled away from the house and moved down the rural road.
The house sat still behind them, the winter morning unchanged outside, cold, gray, empty. Susan’s coat remained hanging by the door. The coats of the young ones were still there, too. They had not been allowed to take them. Whatever Susan had understood about what was happening, whatever she was thinking in those minutes in the vehicle, she was still alive.
She was still trying to read the situation, to find some angle, some possibility. The Bronco drove toward a pond located southeast of the Broock residence, not far from Bolin’s property. It was a place Mark knew. A familiar location on the landscape he had inhabited for years. It was not an accidental destination. The vehicle stopped at the edge of the pond.
Susan, Kyle, and Adrian were brought out of the vehicle to the water’s edge. The morning was still. The pond was still. The cold held everything in place. Mark Christeson was in control of what happened next, and he acted with a deliberateness that spoke to someone who had made a decision and intended to see it through.
At the edge of the pond, southeast of the Broock residence, and close to the Bolin property, Mark Christeson turned on Susan Broock first. He kicked her hard in the ribs. She went down. He had a bone knife with him. He used it to cut her throat. He did not do it once. He cut her throat twice. Susan did not die immediately. She was severely wounded, bleeding at the water’s edge, but she was still alive when Christeson turned to Kyle.
He attacked Kyle’s throat with the same knife. Then he took Kyle and held him in the water until he was gone. Adrian tried to free herself. Her wrists were still bound, but she struggled. Carter held her legs. Christeson pressed down on her neck with his hands and kept pressing until she stopped moving. Carter then pushed her into the pond.
Susan was still fighting, despite everything that had been done to her, the kicks, the knife, the blood. She still trying to survive. Christeson and Carter took her and threw her into the water on top of where her two young ones had gone. She drowned in the pond. Christeson used a stick to push the bodies further out into the water.
Mark Christeson and Jesse Carter got back into the Ford Bronco. The vehicle that had belonged to Susan Brok now carried everything they intended to take with them. The television, the VCR, the household items they had loaded up at the house. The gun. The two of them. They drove away from the pond and back to the Bolin property first, long enough to gather their own belongings and pack what they needed for a cross-country escape.
Then they pointed the Bronco west. They were leaving Missouri. Behind them, in a pond on a gray February morning in Maries County, three members of the Brok family lay in the water. The house they had left was warm and quiet. The coats were still by the door. The winter morning continued as it had been, cold and still, and completely indifferent to what had just taken place at the edge of that water.
Nobody knew yet. Nobody came to the house that day. Sunday passed. The cold held. The pond sat undisturbed. Mark and Jessie drove west through Missouri and into the open country beyond, selling Susan’s belongings along the way. Household items traded for gas money, for food, for the practical currency of two young men moving fast with no destination in mind beyond away.
Somewhere in Texas, Mark stopped long enough to pawn the 16-gauge shotgun. The transaction left a record. It always does in pawn shops. The gun went into storage behind the counter of a shop in Texas, logged in a ledger, waiting. The Bronco kept moving west. In Vichy, Missouri, the Brok house sat closed and dark. Sunday had passed.
Now Monday. The young ones had not shown up at school. Susan had not appeared at work at Talema Industries. The silences were beginning to accumulate, but no one had called the police yet, not quite yet. Susan’s sister, Kay Hayes, was the first to register genuine alarm. The family had plans to get together on Sunday, February 1st.
Susan and the young ones were expected. When they didn’t arrive, Kay assumed there might be a simple reason, the cold, a change of plans, something minor. She told herself not to worry, but by Tuesday evening, when she called Susan’s home and the phone went unanswered, something in her shifted. She tried again. No answer.
She called her sister, Joy Lemons, to ask if Joy had heard from Susan. Joy had not. They compared notes. Neither of them had spoken to Susan since before the weekend. On Wednesday evening, Kay and another family member drove to the Brookes’ house to check on things in person. They knocked. No answer. They tried the door and went inside.
The house was intact. Nothing appeared disturbed in the chaotic way of a struggle. But as they moved through the rooms, the details of what was missing and what remained told a story that didn’t add up. The television was gone. The VCR was gone. Susan’s Ford Bronco was not in its place. But the coats were still hanging by the door, Susan’s coat and the coats belonging to the young ones.
In the first days of February in Missouri, with temperatures at or below freezing, nobody goes anywhere voluntarily without a coat. Not a grown woman, certainly not young ones. The family called the police. Officers from the Maries County Sheriff’s Department responded that night. They secured the Brookes’ residence and began an initial survey of the property.
They found the house in order, but empty. The coats remaining by the door, the vehicle and electronics gone. There were no immediate answers. There was no sign of violence inside the home. The family had simply not been there. Or if they had been, they had left without taking the things they would have taken in any ordinary departure.
That night produced no resolution. Officers secured the scene and prepared for a broader search the following morning. On the morning of Thursday, February 5th, officers with the Missouri State Highway Patrol began an aerial search of the area around the Brookes residence. A patrol helicopter lifted into the gray winter sky and moved over the flat, cold terrain of Maries County.
The fields, the roads, the patches of water scattered across the rural landscape. The helicopter crossed over a pond located southeast of the Brookes house. The pilot and observers saw something in the water below. They brought the helicopter down in a field south of the pond and approached on foot. Susan Brookes, her daughter Adrian, and her son Kyle were found in the water, partially submerged, their bodies still in the cold of the pond.
The family that Kay Hayes had been trying to reach since Tuesday evening had been here all along, within sight of the road, within a half mile of the house where their coats still hung by the door. Maries County was a small, quiet community. People who lived there, raised families there, stayed there across generations, knew their neighbors by name and by history.
The discovery of what had happened to Susan Brookes and her young ones hit the community with a particular force that violent death carries in places where violent death is not a familiar thing. It was not something anyone in that area had been prepared for. It changed the texture of the county immediately and permanently. Officers moved around the perimeter of the pond.
They began documenting what they found. A 16-gauge shotgun shell on the south bank, blood on the leaves and soil nearby, shoe impressions in the frozen ground, two cinder blocks on the west bank, tire impressions leading away from the water toward the edge of the Bowlen property where a garbage pile marked the boundary of the land.
The scene was processed, the bodies were recovered, the medical examiner was notified, and investigators began the work of figuring out who had done this. The investigation was about to move quickly. The Maries County Sheriff’s Department and the Missouri State Highway Patrol began working the case immediately after the bodies were recovered from the pond on February 5th, 1998.
The evidence at the scene gave investigators a starting point. What they needed now was a person or persons to attach to it. The physical evidence was specific. The 16-gauge shotgun shell on the south bank of the pond was traceable by gauge and type. The tire impressions leading away from the water had been left by a vehicle with identifiable characteristics.
The shoe prints in the frozen ground around the scene could be measured. DNA samples had been collected from Susan’s body and from inside the Broocks’ home. The forensic work began in parallel with the investigative work, each track of inquiry feeding the other. At the Broocks’ house, the absent items told their own story.
A television, a VCR, and other household electronics were gone. The Ford Bronco was gone. The vehicle would be the most traceable item, a specific make, model, and license plate that could be flagged through law enforcement systems across the country. Investigators also began reviewing reports and records in the area around the Broock residence.
They were looking for anything that might point to who had been near that house around the time of the family’s disappearance. What they found was a detail that would prove significant almost immediately. On February 1st, the same day Susan and the young ones were last seen alive, a report had been filed noting that two young men from the area had gone missing from a nearby property.
The property was Bolin Hill. The two missing young men were Mark Christeson, 18, and Jesse Carter, 17. They lived approximately half a mile from Susan Broock. The connection was not yet confirmed at that point, but the proximity alone was enough to focus attention. Investigators began looking into who these two young men were, where they might have gone, and whether they had any link to what had happened at the pond.
DNA testing was submitted to the Missouri State Highway Patrol Crime Laboratory. The process would take time, but the samples collected from Susan’s body, from Adrian’s bed in the Broock house, were in the system and being analyzed. If those samples matched anyone already in a database, the connection would be established scientifically without ambiguity.
In the meantime, law enforcement agencies across the country were notified to watch for Susan’s Ford Bronco. The vehicle’s description and plates went out broadly. Two young men from rural Missouri traveling in a stolen Ford Bronco loaded with stolen property driving west. That was the working picture investigators were building.
The Bronco had crossed through Missouri into other states moving steadily toward the west coast. Mark and Jesse were traveling as fast as the road allowed selling pieces of Susan’s household belongings along the way. The television, the VCR, the electronics that had sat in the Broock living room, each item became fuel money, food money, distance between them and what they had left behind.
In Texas, Mark stopped at a pawn shop and exchanged one of the 16-gauge shotguns for cash. The shop recorded the transaction in the way pawn shops are required to by law. The gun entered their inventory. The record of the exchange was made. By the time Christeson and Carter reached California, they had been driving for days.
They arrived in the desert landscape of Eastern California, the Coachella Valley, the flat expanse of Riverside County with its agricultural towns and highway corridors and the particular quality of open Western space that feels to someone fleeing something like a kind of breathing room. They stopped in Blythe, California, a small city on the Colorado River at the California-Arizona border.
Blythe sits on Interstate 10, the cross-country highway that cuts east to west across the southern United States. It was a logical stopping point for two people moving without a plan. But law enforcement had been watching. Riverside County, California is a large and varied stretch of the Inland Empire and desert, a place of highways and transit routes, agricultural land, growing cities, and the constant movement of people passing through on their way somewhere else.
Law enforcement in the county operated with a steady awareness of cross-country traffic and the people who moved through on the major routes. A detective in Riverside County had seen the photographs circulated through law enforcement channels. The images of Mark Christeson and Jesse Carter, along with the description of Susan Broock’s Ford Bronco, had gone out across multiple states in the days following the discovery of the Broock family at the pond.
It was the kind of bulletin that traveled fast when the circumstances were as serious as these. A stolen vehicle, missing property, and three people found dead in a Missouri pond. On February 9th, 1998, 8 days after Susan Broock and her young ones were killed, the detective made the identification. The Bronco and the two young men from Missouri were located in Blythe, California, near the Colorado River at the state’s eastern edge.
Mark Christeson and Jesse Carter were taken into custody. The Bronco was secured. Whatever remained of the items they had taken from the Broock home was now in law enforcement hands. The journey that had begun at the Bolin property on the morning of February 1st, the walk to Susan’s house, the drive to the pond, the long flight west, had ended in a small California desert town, 8 days and roughly 2,000 miles from where it started.
The two were returned to Missouri to face questioning. When detectives sat down with Mark Christeson, he invoked his right to an attorney. He said nothing about the events of February 1st. He gave nothing to investigators directly. That was his right, and he exercised it. Jesse Carter was different. Carter spoke.
He told investigators what had happened, laid out the full sequence of events from the night of January 31st, when the two of them had decided to run, through the morning of February 1st, the walk to the Broock house, what happened inside, the drive to the pond, what happened there. His account was detailed and specific.
Carter’s statement to investigators became the backbone of the prosecution’s case. It matched the physical evidence at every point. The DNA results, when they came back from the Missouri State Highway Patrol Crime Laboratory, confirmed what Carter had said about what Christeson had done in the Broock home. The genetic material found on Susan’s body and on Adrian’s bed sheets matched Mark Christeson’s profile.
The shotgun pawned in Texas was ballistically confirmed as the weapon that had fired the shell recovered from the South Bank of the pond. The evidence assembled into a complete picture. Carter’s testimony gave it narrative structure. The forensic results gave it scientific confirmation. The physical items recovered from the Bronco, the pawn shop record in Texas, the shoe impressions and tire tracks at the scene, each element fit into a case that left very little room for alternative explanations.
Prosecutor Terry Daily Swartzy was the Maries County prosecutor handling the case. She reviewed the evidence as it came together and spoke publicly about it with a directness that reflected how the community around her was processing what had happened. She described the killings as brutal. She said plainly that if there was anyone who deserved the death penalty, it was this defendant.
The charge against Mark Christeson was triple first-degree murder. It was the most serious charge the state of Missouri could file, carrying as its potential penalty the ultimate sentence under Missouri law, death. Jesse Carter, who had agreed to cooperate with prosecutors, would face separate proceedings.
His testimony against Christeson would be a central element of what was now moving toward a trial. A trial date would be set, but before that happened, the legal machinery of the state had to work through a set of procedural steps, a process that would eventually lead both Christeson and the case to Vernon County, where a jury of ordinary Missouri citizens would be asked to hear the evidence and decide what justice looked like in the murder of a single mother and her two young ones.
After both cousins were formally charged, Carter’s case was resolved separately through a plea agreement. He would testify against Christeson in exchange for three life sentences without parole. Christeson faced three counts of first-degree murder with the death penalty in play. Before trial, the defense secured a change of venue from Maries County to Vernon County due to extensive local publicity.
Several pre-trial motions were fought and lost. The defense’s request for individual juror questioning was denied. A motion to withdraw trial counsel was denied. And a request for a continuance after Carter was added as a witness was also denied since his confession had been in defense counsel’s hands for over a year.
At trial, prosecutor Terry Daley Swortz built the case layer by layer. DNA evidence from the Missouri State Highway Patrol Crime Laboratory confirmed Christeson’s presence in Adrian’s bedroom with Susan Brok. The shotgun he pawned in Texas was ballistically matched to the shell found at the pond.
Carter testified in full detail about everything that happened from the moment they left Bolin Hill to the moment they drove away from the water. An additional witness testified about something that had happened during the months between Christeson’s arrest and his trial. Wagner had shared a cell with Christeson in the Vernon County Jail in February 1999.
He testified that Christeson had subjected him to a sexual assault during that time. This testimony was not about the Brok murders directly. It was penalty phase evidence introduced to establish a pattern of behavior that the prosecution argued the jury should consider when deciding the appropriate sentence.
When the guilt phase concluded and the jury retired to deliberate, they did not take long. The evidence was comprehensive. The testimony was specific. The forensic confirmation was thorough. The jury returned verdicts of guilty on all three counts of murder in the first degree. Then the penalty phase began. In Missouri capital cases, the same jury that determines guilt also hears evidence in the penalty phase and makes a sentencing recommendation.
The prosecution presented its case for death. The defense presented whatever mitigating evidence it had assembled. The jury found three aggravating circumstances specifically in the murders of Adrian and Kyle, that each murder was committed during the unlawful killing of the other, and that both murders involved depravity of mind, making them outrageously and wantonly vile.
The jury returned penalty recommendations on all three counts, death. On October 8th, 1999, Judge Darnell accepted the jury’s recommendation and formally sentenced Mark Anthony Christeson to death three times over, once for each member of the Broock family. Jesse Carter, for his role in the murders, received three life sentences without the possibility of parole.
He would not be eligible for release. He would not receive death. The difference between their sentences came down to one thing. Carter had agreed to testify and Christeson had not. The Broock family had their verdict. The Maries County community that had mourned through the spring and summer and into the fall of 1998 now had an outcome in the courtroom.
Prosecutor Schwarze, speaking publicly about the case, said what she had said before and meant, “If there was anyone for whom this sentence was appropriate, it was this defendant.” Mark Christeson was removed from the courtroom and transferred to Missouri’s death row. He was 19 years old when he arrived. He would spend the next 18 years there.
Christeson was transferred to death row. The Missouri Supreme Court affirmed his conviction in 2001. His appointed federal habeas attorneys, Eric Butts and Phil Horwitz, then missed the one-year filing deadline by 117 days, causing the federal court to dismiss his petition without ever reviewing its substance.
Butts and Horwitz concealed this failure from Christeson for nearly a decade, met with him only a handful of times, never hired any experts, and ignored his repeated letters asking for case updates. Christeson, due to his cognitive limitations, had no way of knowing what had happened and was entirely dependent on attorneys who were lying to him about the status of his case.
The error comes to light in 2014. With an execution date set for October 29th, the failure by Butts and Horwitz finally surfaced. New attorneys Maragan and Perkovich attempted to substitute in as counsel, but were blocked at every turn. The US Supreme Court intervened less than 24 hours before the execution, issuing a stay and ordering that conflict-free counsel be appointed.
The district court then approved only $10,000 of the $161,000 funding request the new attorneys needed to properly investigate the case. Working with severely limited resources, Maragan and Perkovich fought on multiple legal fronts simultaneously, appealing the funding denial, arguing for equitable relief, and seeking Eighth Circuit review.
In October 2016, while those appeals were still active, Missouri set a new execution date of January 31st, 2017. The Eighth Circuit then compressed its briefing schedule dramatically, and with only 13 days left before the execution, ordered an evidentiary hearing to be held within 48 hours. The final hearing.
The rushed hearing produced only the testimony of Butts and Horwitz themselves, who defended their conduct despite having no documentary evidence to support their claims. The district judge found them credible and denied relief. Every subsequent appeal to the Eighth Circuit, then to the US Supreme Court, was denied.
Justice Ruth Bader Ginsburg did not join that denial silently. A spokesperson for the court confirmed that Ginsburg had noted she would have granted the stay. Her dissent from the court’s refusal to intervene was the only public acknowledgement from within the Supreme Court that what had happened to Mark Christeson’s federal case was something she found legally troubling.
Missouri Governor Eric Greitens, who had taken office earlier that month, received the clemency petition Merigan submitted on Christeson’s behalf. Greitens reviewed it. He issued a statement saying he had thoughtfully considered the facts of the case and had conducted a comprehensive review of the request. He denied clemency.
His decision, he said, upheld the verdict handed down by the jury and affirmed by the courts. Attorney General Josh Hawley issued his own statement arguing that Christeson was not hampered by any intellectual incapacity and that the legal process had run its course. January 31st, 2017, the execution window opened at 6:00 p.m.
at the Eastern Reception, Diagnostic and Correction Center in Bonne Terre, Missouri. Christeson’s family members were present as witnesses. 14 protesters stood outside the prison walls. Inside the prison, the preparations were complete. Mark Christeson spent the day in the knowledge of what was coming.
He had been on death row for nearly 18 years. He had come within hours of execution once before. In October 2014, when the Supreme Court stayed the injunction with less than a day to spare. That experience and the years of legal proceedings that followed it had given him a prolonged and specific awareness of what it meant to exist at the intersection of the legal system and mortality.
His final meal was a bacon cheeseburger, fries, a slice of pecan pie, and a soda. It was a plain American meal. There was nothing remarkable about it except for the context in which it was eaten. Merigan’s final appeals had been exhausted. The Supreme Court had denied the stay that morning. Governor Greitens had denied clemency.
The Eighth Circuit had not intervened. The District Court had ruled against him. Every door in the federal system had been tried and found closed. The family members who had come to witness the execution gathered in the designated area. Mark’s brother and his sister-in-law were among those present. The Broock family’s representatives were also there on the other side of the witness class.
People who had spent nearly two decades carrying what had been taken from them on a cold February morning in 1998. Harley Broock, the half-sister of Adrian and Kyle, was present. She was 24 years old. She had been five when her brother and sister were killed. She had grown up without them. Had measured the whole arc of her growing years against the absence of two people who should have been in them.
At 6:57 p.m., the lethal injection began. As the drug was administered, Mark Christeson turned toward the witness area where his brother and sister-in-law were standing. He appeared to mouth the words, “I love you.” twice, directing them at his family. Then his eyes closed. He was pronounced dead at 7:05 p.m. CST.
Eight minutes had passed since the injection began. A Department of Corrections spokesman confirmed the time. Sheriff Chris Heightman of Maries County, who had attended as an official witness, spoke to reporters afterward. He said it had been a heinous crime. He said he was glad to see justice finally served. He said he had regrets for the family that it had taken so long, but he hoped it provided closure.
Outside the prison, 14 protesters stood in the cold Missouri night holding whatever signs or candles they had brought, present in the way that people who oppose capital punishment make themselves present at these moments. As a form of witness, as a statement that another life had been taken by the state, regardless of the circumstances that preceded it.
The execution of Mark Anthony Christeson was Missouri’s first since May 2016. He was the 37th year of his life.
