Inside the Execution of David Hosier: The Missing Evidence, the Ignored Brain Damage, and the Haunting Final Words
The Final Breath in Bonne Terre
On the evening of June 11, 2024, the heavy, mechanized doors of the Eastern Reception Diagnostic and Correctional Center in Bonne Terre, Missouri, sealed shut on the outside world. Inside the sterile confines of the execution chamber, the air was thick with the weight of absolute finality. At exactly 6:00 p.m., a sixty-nine-year-old man lay strapped to a medical gurney. He was a United States Navy veteran. He was a former emergency medical technician. He was a former firefighter. For decades, he was a man who had dedicated his professional life to running toward emergencies when everyone else was running away. Now, he was the emergency, and there was no one coming to his rescue.
The man was David Russell Hosier, and the state of Missouri had determined that it was time for him to die.
A single, lethal dose of pentobarbital was administered into his bloodstream. Witnesses watched in solemn silence as the heavy chemicals took hold. Hosier turned his head twice. He took two deep, laboring breaths. And then, he went completely still. Eleven minutes later, at 6:11 p.m., a medical professional stepped forward and pronounced David Russell Hosier legally dead. He became the second person to be executed in the state of Missouri in the year 2024.
Executions often bring a sense of closure to the agonizing chapters of violent crime, but the death of David Hosier offered no such comfort. Instead, it left behind a chilling void. The narrative of his guilt, carefully constructed by prosecutors over a decade prior, lacked the foundational pillars of modern forensic science. In the brutal double murder of Angela and Rodney Gilpin, there was no confession. There was no matching DNA recovered at the crime scene. There were no fingerprints linking Hosier to the weapon or the victims’ apartment. There was not a single eyewitness who could place him pulling the trigger. He was convicted entirely on circumstantial evidence and a timeline of escalating, terrifying obsession.
As he faced his final moments on earth, Hosier’s last words echoed with the same defiance he had maintained for fifteen grueling years on death row: “I’ve been able to speak the truth of my innocence.“
This lingering defiance begs a terrifying question that the state of Missouri has long considered closed, but the public continues to ask: Did the justice system execute a cold-blooded, calculating killer who skillfully masked his tracks, or did they execute an innocent man suffering from profound, undocumented brain damage? To unravel the complex web of guilt, trauma, and circumstantial justice, one must journey far back from the execution chamber in Bonne Terre. This story does not begin with a double homicide in Missouri. It begins decades earlier, with the shattering blast of a handgun on a staircase in Indiana.
The Echoes of Logansport: A Legacy of Service and Tragedy
The foundation of David Hosier’s life was not built on criminality or malice; it was built on a deep-seated reverence for public service. Born on February 10, 1955, in Logansport, Indiana, David entered a family where wearing a uniform was the ultimate measure of a man’s worth. His father, Glenn R. Hosier, was a towering figure in the community. Glenn was a World War II Navy veteran who returned home to serve seven years as a dedicated Logansport City police officer before advancing to the prestigious ranks of the Indiana State Police in the exact year his son David was born.
For young David, his father was not just an authority figure; he was a superhero. Glenn was a highly present and engaging father. The pair were inseparable. David was known as his father’s “little pal” and his faithful sidekick. They spent countless hours hunting in the dense Indiana woods and camping beneath the stars. David would frequently ride along in his father’s state patrol car, his wide eyes watching the man he idolized most as he protected the community. For a boy growing up in the mid-twentieth-century Midwest, life was idyllic. It was a childhood anchored by safety, respect, and unconditional love.
But that safety was an illusion, shattered permanently on the evening of April 13, 1971.
A dangerous fugitive named Lindsey Mallard, wanted for the brutal murder of a woman named Judy Rucker Wells, had been tracked to a residence on West Canal Street in Peru, Indiana. Sergeant Glenn Hosier, operating alongside officers from the Peru Police Department and the Miami County Sheriff’s Department, surrounded the property. Demonstrating the courage that defined his career, Sergeant Hosier led the tactical entry up the narrow, dimly lit staircase.
As he reached the top and turned the corner, Lindsey Mallard was waiting. Mallard fired a .32 caliber handgun at point-blank range, striking Sergeant Hosier directly in the head. The trailing officers instantly returned a hail of gunfire, killing Mallard on the spot, but the catastrophic damage to the Hosier family had already been inflicted.
Glenn Hosier was rushed to Indianapolis for desperate emergency surgery. He fought for his life for thirteen agonizing days before finally succumbing to his devastating injuries on April 26, 1971. He was laid to rest at Mount Hope Cemetery in Logansport, leaving behind a grieving community and a completely shattered family.
David was just sixteen years old when his hero was taken from him. On the night of the shooting, he had been upstairs in his bed, suffering from a minor illness, while his mother, Martha, sat downstairs reading, waiting for her husband to return home safely just as she had done hundreds of times before. Then, the dreaded knock echoed through the house. Two solemn state troopers stood at the front door.
Decades later, David would recall that exact, life-altering moment with a haunting quietness. “I heard mom downstairs crying, and when that happens, you know what it usually means,” he recounted.
In the early 1970s, society lacked the comprehensive trauma support networks, grief counseling, and psychological interventions that exist today. The Hosier family was left to drown in their sorrow. Martha, entirely consumed by the agonizing loss of her husband, struggled to carry the immense emotional weight of her children. David, standing precariously on the threshold between adolescence and manhood, was completely untethered. The anchor of his universe was gone. Family members would later reveal heartbreaking memories of a teenage David sneaking out in the dead of night to sit beside his father’s fresh grave, weeping uncontrollably in the dark.
His sister, Keysha, later articulated the profound psychological damage that moment inflicted. “My dad’s death was just like a crater,” she explained. “And David fell into that crater.“
A Facade of Stability: The Uniformed Years
Following the traumatic loss of his father, the trajectory of David’s life shifted drastically. He was sent away to a strict military school, a move that only deepened his profound sense of isolation. He had not only lost his father; he had lost the comforting familiarity of his childhood home and his supportive community. Socially cut off and grieving, David could have easily spiraled into juvenile delinquency. Instead, the ingrained legacy of his father pushed him in the opposite direction. He sought solace in the only structure that made sense to him: the uniform.
In September 1974, at the age of nineteen, David enlisted in the United States Navy. He did not merely serve a quiet, background role. He excelled, demonstrating a high level of intelligence and reliability that earned him an assignment to the elite Naval Communications Unit. He was granted a top-secret security clearance, an honor reserved for individuals who undergo rigorous background checks and psychological evaluations. He proudly walked the highly secure halls of the Pentagon, serving his country with distinction. He transitioned to the Naval Reserve, completing a combined six years of honorable military service by 1980.
Following his discharge, David sought a quiet place to lay down roots. During a visit to his sister in Jefferson City, Missouri, in the late 1970s, he met a woman and decided to stay. He built what, from the outside, appeared to be an incredibly stable, admirable second act. Continuing his lifelong compulsion to protect and serve, David became a professional firefighter and an emergency medical technician. He was the man sprinting into burning residential buildings to save trapped families; he was the medic administering life-saving CPR on the pavement. By every visible, public metric, David Hosier was a hero. He was actively carrying on the noble legacy of Sergeant Glenn Hosier.
But beneath the sturdy uniform, the psychological crater from 1971 had never been filled. The unprocessed trauma was festering, slowly eroding his mental stability from the inside out.
The Fracturing of a Mind: Trauma, Illness, and Brain Damage
The facade of the heroic first responder began to publicly crack in 1986. David’s mental health deteriorated in ways that could no longer be hidden behind a badge or a fire hose. The pressure of his untreated trauma, combined with the extreme, daily stress of his emergency medical career, culminated in a severe psychological collapse. He was involuntarily committed to a state psychiatric hospital for intervention. Medical professionals evaluated his erratic behavior and delivered a stark diagnosis: severe depression coupled with psychotic features and bipolar disorder.
His personal life began to mirror his internal chaos. He had remarried in 1980 and fathered a son and a daughter, but the marriage could not withstand the hurricane of his mental illness. The relationship ended in divorce in 1986, the same year of his hospitalization. The man who had spent his life saving others was rapidly losing the ability to save himself.
The downward spiral accelerated dangerously in 1992 when David was arrested for physically battering a girlfriend. The protector had become the aggressor. He pleaded guilty to the charges and was sentenced to eight years in the state penitentiary. The heroic firefighter was now a convicted felon. He served his time and was released on parole in 1997, attempting to piece together the shattered fragments of a ruined life.
However, the most critical turning point in the tragic pathology of David Hosier occurred a decade later, in 2007.
David suffered a severe transient ischemic attack—a major stroke. He was rushed to Audrain Medical Center in Missouri, where doctors fought to stabilize him. He survived the acute medical emergency, but the aftermath was permanently devastating. Extensive medical records from the hospital meticulously documented the fallout: the stroke had caused lasting, irreversible brain damage.
Years later, his appellate public defender, Amy Bartholow, would stand before the highest court in the state and bluntly articulate the reality of his condition. “David Hosier’s brain,” she stated emphatically, “is dead in places.“
The biological implications of this brain damage were monumental. The specific areas of the brain affected by the stroke directly governed his emotional regulation, his judgment, and his critical impulse control. The biological braking system that stops a healthy person from acting on dark, obsessive, or violent thoughts had been physically destroyed.
This devastating medical event occurred in 2007. The brutal murders of Angela and Rodney Gilpin occurred in 2009. Yet, when David Hosier’s life was placed in the hands of a jury in 2013, the concept of his stroke-induced brain damage—the physical death of the very tissues controlling his impulses—was entirely absent from the narrative presented by the defense. It was a catastrophic omission that would haunt the case for eternity.
The Fatal Intersection on West High Street
By the year 2008, David Hosier was in his early fifties. The top-secret clearances, the Navy honors, and the firefighting commendations were distant memories. He was living a quiet, solitary existence in an ordinary apartment building on West Main Street in Jefferson City. The neighborhood was unassuming, a blue-collar block where people kept their heads down and minded their own business.
Directly across the shared asphalt parking lot sat another residential building on West High Street. Both properties were owned and managed by a local landlord named Dennis Prenger. David, possessing an innate mechanical aptitude from his military and municipal days, performed various odd jobs and maintenance work around the sprawling complex for Prenger. In exchange for his labor, David was granted trusted access to the landlord’s secure storage room—the exact location where the master keys to every apartment in the complex were kept hanging on hooks. It was a seemingly mundane administrative detail that would soon take on a deeply sinister significance.
It was within this confined, overlapping geographic orbit that David crossed paths with Angela Yvonne Gilpin.
Born on December 20, 1963, Angela was a hardworking mother of two grown sons. She managed the bustling Bee Line convenience store in nearby Wardsville, a demanding job that required long hours and early mornings. At the time she moved into the West High Street apartment building, her personal life was in a state of profound transition. She was estranged from her husband, Rodney Dean Gilpin. Rodney, born in 1948, had shared twenty-one years of marriage with Angela before the relationship fractured, leading to their painful separation.
Living across the parking lot from each other, David and Angela naturally gravitated together. Sometime between 2008 and 2009, a romantic relationship blossomed. According to testimonies from those who lived nearby, this was not a fleeting encounter or a secretive affair. It was highly visible. A neighbor named Jo Dean Scott later testified that David openly referred to the dynamic as an affair, while others in their tight-knit community described them as a “good dating couple.” To outside observers, they appeared to genuinely care for one another, finding comfort in their shared proximity.
But in August 2009, the trajectory of their romance hit an immovable wall. Angela made a monumental life decision. After considerable soul-searching, she chose to reconcile with Rodney. They had shared over two decades of history, raised two sons together, and built a foundation she was not ready to permanently abandon. The relationship with David was abruptly and unequivocally terminated. Angela chose her husband.
For a man with a healthy, functioning brain, such a rejection triggers deep emotional pain, eventual acceptance, and moving on. For David Hosier—a man carrying the unresolved trauma of his father’s violent murder, burdened by diagnosed bipolar disorder, and suffering from documented, stroke-induced brain damage that physically annihilated his impulse control—acceptance was biologically and psychologically impossible.
The Descent into Obsession: A Tragedy Foretold
The termination of the relationship did not result in a clean break; it ignited a terrifying, escalating campaign of obsessive terror. David simply refused to accept that Angela was gone. He began desperately leveraging the surrounding community to force her back into his life.
He heavily targeted a mutual neighbor, Jerilyn Bleckler, leaning on her incessantly to act as a mediator. David aggressively pressured Bleckler to intervene, demanding she convince Angela that returning to Rodney was a mistake. When Bleckler refused to insert herself into the volatile situation, David’s desperation morphed into dark frustration directed at her as well. He confessed to Bleckler that his love for Angela was permanent and consuming. He insisted, with delusional grandiosity, that he was vastly superior to Rodney.
And then, the desperation curdled into a chilling threat. In a conversation that would later echo through a silent courtroom, David told Bleckler that if Angela did not come back, he would “put a stop to it somehow.”
Across the following weeks, Angela’s life transformed into a waking nightmare. She was no longer just managing the emotional complexities of a reconciled marriage; she was being hunted. Her existence became defined by sheer, unadulterated fear.
She took desperate, documented steps to protect herself. Angela wrote a direct, pleading letter to their mutual landlord, Dennis Prenger, explicitly stating that she could no longer safely reside next door to David Hosier. She needed immediate relocation. Her written words left absolutely zero room for misinterpretation: “He scares me,” she penned frantically. “I don’t know what he will do next.”
Recognizing the escalating danger, Angela escalated her pleas to the legal system. She bravely marched into the Cole County courthouse and officially filed a petition for a legal protective order against David. The legal application she filled out was a harrowing window into her daily psychological torment. In her own handwriting, she documented the systematic destruction of her peace. She wrote that David “knows everywhere I go, who I go with, who comes to my home.” She swore under oath that he was actively stalking and harassing her every single day, turning her neighborhood into a prison.
But the document contained an even darker prophecy. Angela explicitly expressed her absolute terror that David Hosier was going to shoot her and her husband. She put her premonition of her own murder formally on the judicial record, begging the courts to intervene before the violence materialized.
Her fears were entirely justified. Another neighbor confidentially informed law enforcement that David had begun openly vocalizing an incredibly dangerous, possessive mantra: If he could not have Angela Gilpin, then absolutely no one else would.
The Eve of Destruction: Voicemails and Warnings
The boiling point was reached on the fateful evening of September 27, 2009.
Inside the apartment on West High Street, the atmosphere was a picture of domestic normalcy. Jerilyn Bleckler spent the Sunday afternoon relaxing with Rodney and Angela, watching a Kansas City Chiefs football game broadcast on television. They were together, they were safe, and they were attempting to rebuild the ruins of their twenty-one-year marriage. Angela was alive. Rodney was alive.
Just across the asphalt parking lot, David Hosier was completely unraveling.
As the football game played on the television, David began making a frantic series of phone calls. He repeatedly dialed Jerilyn Bleckler’s number. When she intentionally stopped answering to avoid his relentless pressure, he began leaving dark, threatening messages on her answering machine. These audio recordings would later become the devastating centerpiece of the prosecution’s case.
The voicemails were laced with venom and finality. In one recorded message, David’s voice dripped with exhaustion and rage. He berated Bleckler for failing to accomplish what he had demanded of her. And then, he crossed the point of no return. His exact words, immortalized on magnetic tape, were terrifyingly clear: he stated he was “going to finish it.”
His erratic behavior did not stop with Bleckler. Shortly before 10:00 p.m. that same Sunday night, David dialed another neighbor, Jo Dean Scott. His tone was ominous. He informed her that he needed to stop by her apartment immediately to drop off some crucial items. He explained he was bringing her a set of keys, accompanied by highly specific written instructions detailing exactly how she should manage and dispose of his personal belongings “if anything happened to him.” It was the logistical preparation of a man who did not expect to be coming home.
When Scott, feeling uneasy, told him she was too tired to receive visitors at that hour, David casually replied that he would simply leave the items on the hood of her car in the parking lot. Before he disconnected the call, he delivered one final, chilling declaration to Scott. He stated plainly that he was preparing to “eliminate his problems.”
Finish it.Eliminate his problems.
These two horrific phrases were sitting quietly on answering machines and lingering in the memories of his neighbors as the sun finally set over Jefferson City. The stage was set for an unimaginable tragedy.
September 28, 2009: The Blood in the Doorway
The next morning arrived with a deafening silence. It was Monday, September 28, 2009.
At approximately 3:00 a.m., the 1,100 block of West High Street was blanketed in the heavy, quiet darkness of the pre-dawn hours. The apartment complex was still, its residents deep in sleep.
A woman named Jennifer Stubbs, a resident of the building, was just arriving home. She had been away on a personal trip and was exhausted, hauling her luggage toward the front entrance. She inserted her key, turned the lock, and pushed open the heavy front door to the shared interior hallway. As she stepped over the threshold, her eyes adjusted to the dim light.
Lying on the floor, tangled together in a horrific scene of unimaginable violence, were two bodies blocking the doorway of apartment number two.
Jennifer Stubbs immediately scrambled for her phone and dialed 911, her voice shaking as she reported the gruesome discovery.
When the Jefferson City Police Department and emergency medical personnel arrived, the true horror of the scene became apparent. Angela Yvonne Gilpin, forty-five years old, lay dead. She had been subjected to a brutal barrage of gunfire. The medical examiner, Dr. Carl Stacy of Boone County, would later conduct the autopsy and confirm the devastating extent of her injuries. Angela had been shot a total of six times. Four heavy caliber rounds had torn through her torso, and two rounds had been fired directly into her head.
Rodney Dean Gilpin, sixty-one years old, lay lifeless beside his wife. He had been shot three times squarely in the chest, with a fourth bullet shattering his elbow. He had never even made it out of the apartment doorway.
The forensic details of the crime scene painted a highly specific picture of the execution. Dr. Stacy noted a critical lack of forensic evidence on the victims’ skin and clothing: there was absolutely no soot, and there was no stippling (the tiny, unburned particles of gunpowder that embed in the skin when a gun is fired at close range). The complete absence of soot and stippling meant the shooter was not engaging in a close-quarters struggle. The weapon had been fired from a cold, calculated distance of at least twelve to twenty-four inches away. They were gunned down from the hallway before they even had a chance to react.
Investigators quickly pieced together why Angela was awake and fully dressed at three in the morning. As the dedicated manager of the Bee Line convenience store, she was simply opening the front door of her apartment to leave for her grueling early morning shift. The killer had known her exact schedule. They had waited in the dark shadows of the communal hallway, lying in wait for the precise moment she turned the knob.
When detectives canvassed the terrified apartment building, they interviewed neighbors who reported hearing disturbing sounds in the night. A few residents recalled hearing what sounded like brief “pops” echoing through the walls sometime between 3:15 and 3:30 a.m. However, the auditory evidence was maddeningly sparse. Nobody had seen a shooter fleeing the scene. Nobody had heard an argument preceding the violence. There was no screaming, no scuffle, no sounds of a desperate plea for life. There was only the sudden, sharp crack of gunfire, followed instantly by the heavy, suffocating return of silence.
As crime scene technicians meticulously processed the bloody hallway, a detective searching through Angela’s purse discovered a heartbreaking piece of paper. It was her copy of the application for the legal protective order against David Hosier.
It was the very document where she had chronicled his obsessive stalking. It was the paperwork where she had explicitly warned the justice system that he was going to shoot her and her husband. She had filed the desperate petition on September 15, 2009—exactly thirteen days before she was slaughtered.
The ensuing investigation uncovered a staggering, fatal loophole in the judicial process that allowed the murders to occur. Judge John Beedham had officially scheduled a court hearing to review Angela’s petition for a protective order on September 24. To make the order legally binding, the court required the physical document to be served to the respondent. Cole County Sheriff’s deputies had diligently traveled to David Hosier’s apartment on West Main Street to hand him the papers.
However, they were met with an empty apartment. They were informed by neighbors that Hosier had recently been evicted and had allegedly moved out of the state entirely. Because the deputies could not physically locate Hosier to serve him the paperwork, the legal process ground to a halt.
Just four days before Angela and Rodney’s bullet-riddled bodies were discovered in the hallway, Judge Beedham formally dismissed the protective order petition. The law dictated that without physical service, the order could not take effect. Angela had followed every rule. She had begged the legal system to build a wall between her and the man she knew would kill her. The law, blinded by procedural bureaucracy, failed to reach him in time.
The landlord, Dennis Prenger, was absolutely devastated when he learned of the murders. He confirmed to homicide detectives that he had, in fact, been actively evicting David Hosier. The eviction was not for unpaid rent; it was explicitly due to Hosier’s increasingly terrifying and erratic behavior toward Angela. Prenger revealed another alarming detail: he had no idea that Hosier currently had active, out-of-state warrants for his arrest regarding previous infractions. The web of Hosier’s instability was far wider than anyone in Jefferson City had realized.
When Jefferson City police officers executed a search warrant on Hosier’s now-empty apartment, they did not find the suspect, but they did find an ominous clue left behind: loose ammunition scattered across the residence. The man was gone, heavily armed, and highly dangerous.
The Manhunt and the Ghost Gun
Jefferson City Police Captain Mike Smith wasted no time. Recognizing the extreme flight risk and the lethal capability of the suspect, Smith issued a nationwide all-points bulletin (APB) to thousands of law enforcement agencies across the country. The target was highly specific: authorities were hunting for David Hosier, believed to be driving a 2000 black Pontiac Grand Am.
In a crucial display of modern investigative technique, detectives quickly secured a warrant to ping Hosier’s cellular phone. The digital breadcrumbs painted a clear path of flight. The data showed the phone moving rapidly south and west, speeding away from the bloody scene in Missouri, crossing the state border, and pushing deep into Oklahoma.
The net began to aggressively close. Approximately eight hours after Jennifer Stubbs had made the horrifying discovery in the hallway, a massive coalition of law enforcement agencies caught up with the black Pontiac.
In Cherokee County, Oklahoma, the sheer force of the manhunt descended on the highway. Deputies from the Cherokee County Sheriff’s Office, heavily armed troopers from the Oklahoma Highway Patrol, officers from the Tahlequah Police Department, and even specialized Rangers from the Oklahoma Scenic Rivers Commission converged in a highly coordinated, high-speed pursuit.
When the armada of flashing red and blue lights attempted to force the Pontiac to a halt, Hosier initially refused to surrender, aggressively attempting to flee. A tense chase ensued down the Oklahoma asphalt. Eventually, realizing he was completely outgunned and outmaneuvered, Hosier slammed on the brakes.
As he stepped out of the vehicle, surrounded by dozens of drawn weapons and screaming officers, Hosier did not put his hands up in immediate surrender. Instead, he stared directly at the barricade of police officers and delivered a chilling, suicidal command: “Shoot me,” he yelled over the sirens. “And get it over with.”
The officers exercised extreme restraint, advancing on Hosier and taking him into custody without firing a single shot. He was heavily shackled and transported to the Cherokee County Detention Center in Tahlequah, Oklahoma, to await extradition.
Meanwhile, Jefferson City homicide detectives immediately drove the hundreds of miles to Tahlequah to personally execute the search warrant on the black Pontiac Grand Am. What they uncovered inside the trunk and cabin of the vehicle was nothing short of a mobile armory, a terrifying collection of weaponry that painted a portrait of a man prepared for an absolute massacre.
The inventory was staggering. Detectives pulled out fifteen separate firearms. Every single weapon was fully loaded and ready to fire.
The crown jewel of the deadly collection, and the item that would immediately become the focal point of the double homicide investigation, was a World War II-era Sten submachine gun. This was not a standard weapon purchased over the counter at a sporting goods store. It was a “ghost gun.” Hosier, utilizing his profound mechanical skills, had illegally assembled the fully automatic weapon himself from a mail-order parts kit. Because it was built by hand from disparate components, the weapon possessed no serial number and existed on absolutely no government registry.
Alongside the illegal submachine gun and the fourteen other firearms, detectives cataloged a disturbing cache of tactical gear. They found over four hundred rounds of heavy ammunition. They discovered a military-grade bulletproof vest. Tucked away were a heavy iron crowbar, boxes of sterile latex medical gloves, a homemade police-style tactical baton, and a large hunting knife.
But nestled among the bullets and the body armor, resting innocently on the front seat of the car, was a piece of evidence that spoke louder than any firearm. It was a handwritten note. The ink scrawled across the paper read like a manifesto of fatal jealousy: “If you are going with someone, do not lie to them. Be honest with them if there is something wrong. If you do not, this could happen to you. People do not like being messed with, and after so much of this, they can go off the deep end.”
When Oklahoma investigators pushed a copy of the note across an interrogation table and asked Hosier to explain it, he stared blankly, claiming he had absolutely no recollection of ever writing the words. When pressed to explain why he was fleeing the state with a car loaded with fifteen loaded weapons, body armor, and four hundred rounds of ammunition just hours after his ex-lover was brutally murdered, his excuse was equally baffling. He calmly told the detectives that he had simply been taking a long, spontaneous drive to “clear his head,” and that the massive, illegal arsenal in his trunk was merely “for hunting.”
The police had their suspect. They had the motive. They had an arsenal. What they did not know was that the forensic science was about to fight against them.
A Trial of Circumstances and Silence
The wheels of justice turn agonizingly slow, especially in capital murder cases. Four long years passed between the horrific morning Jennifer Stubbs dialed 911 and the morning a jury was finally seated in a Cole County courtroom to decide if David Hosier should live or die.
The stakes could not have been higher. Cole County Prosecutor Mark Richardson had formally charged Hosier in late 2009 with a devastating litany of crimes: two counts of first-degree murder, armed criminal action, first-degree burglary, and unlawful possession of a firearm by a convicted felon. By August of 2010, Richardson made his ultimate intention clear to the public: the state of Missouri would be actively seeking the death penalty.
When the trial finally commenced in October 2013, the courtroom became a battleground of narratives. David Hosier was not represented by overwhelmed, junior public defenders. His defense team, consisting of attorneys Janice Zembles and Donald Catlett, were legal heavyweights. As the state’s own assistant attorney general, Greg Barnes, would later emphatically point out to the Missouri Supreme Court, Zembles and Catlett possessed over one hundred and fifty trials’ worth of combined, brutal courtroom experience spanning across Texas and Missouri. They were hardened veterans of the legal system who knew exactly how to dismantle a weak case.
And Prosecutor Mark Richardson’s case, while emotionally compelling, possessed a glaring, terrifying weakness: it rested almost entirely on circumstantial evidence.
In his opening statement, Richardson stood before the jury and wove a powerful, logical narrative. He painted a picture of a rejected, obsessed man who utilized his illicit access to the landlord’s master keys to infiltrate the West High Street apartment building. He described how Hosier, armed with the untraceable, hand-built Sten submachine gun, waited in the dark shadows of the hallway at 3:00 a.m., knowing Angela would be opening her door to leave for the Bee Line convenience store. Richardson described the ruthless, calculated execution of both Angela and Rodney, spraying them with gunfire before they could even scream, and then fleeing across state lines with a car full of weapons.
Richardson paraded the evidence before the jury. He presented the terrifying voicemail where Hosier’s own voice promised to “finish it.” He displayed the handwritten manifesto found on the front seat of the Pontiac warning that “this could happen to you.” He brought out another chilling piece of evidence recovered from the car: a yellow legal notepad where Hosier had meticulously written down the specific make, model, and license plate number of Angela Gilpin’s vehicle, proving he was actively tracking her movements. Richardson also brought in a specialized agent from the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) to testify about the lethal nature of the Sten gun, confirming that while buying the parts was legal, the moment Hosier assembled them into a functioning, unregistered ghost gun, he committed a severe federal felony.
The prosecution’s story made perfect sense. It fit every parameter of human logic. But human logic is not forensic science.
When it was time for the defense to speak, Donald Catlett stood up and immediately attacked the scientific void at the core of the state’s case. He pointed out the glaring absences. The police had completely failed to find David Hosier’s DNA anywhere near the bodies. They had failed to pull a single one of Hosier’s fingerprints from the hallway, the doorframe, or any of the ten spent 9mm shell casings scattered across the bloody floor. There was absolutely no physical material placing Hosier at the scene of the crime.
But Catlett’s most devastating attack was directed squarely at the alleged murder weapon itself.
The state desperately needed the jury to believe that the Sten submachine gun found in Hosier’s trunk was the exact weapon used to slaughter the Gilpins. However, the state’s own ballistics expert could not prove it. Missouri Highway Patrol criminalist Todd Garrison had taken the Sten gun to the firing range two days after it was recovered in Oklahoma. Garrison’s objective was to fire test rounds from the weapon and match the microscopic striations on the test bullets and casings to the ten spent shell casings found beside Angela’s body.
The test was an absolute disaster. The hand-built ghost gun was incredibly temperamental. Garrison struggled aggressively just to get the weapon to fire, frequently experiencing complete misfires or managing to squeeze out only a single round before the gun jammed completely.
In his closing argument, Donald Catlett played the video of the state’s own expert wrestling with the malfunctioning gun. He then opened Garrison’s official ballistics report and read the most important word in the entire document to the jury, repeating it like a drumbeat.
“The result is inconclusive,” Catlett boomed across the courtroom. “Inconclusive. Inconclusive.”
Garrison, despite all his scientific equipment, could not make a definitive, microscopic connection between the ten casings found in the hallway and the Sten gun found in Hosier’s trunk. Catlett proposed a completely different theory: the Gilpins were not killed with the malfunctioning submachine gun at all, but rather with a standard 9mm handgun. While the Sten gun fired 9mm ammunition, Catlett reminded the jury that the state had absolutely zero proof that Hosier owned, possessed, or had ever fired a standard 9mm handgun.
Furthermore, Catlett attacked the auditory evidence. Multiple neighbors had reported hearing only three distinct “pops” in the night. If the killer had unleashed a fully automatic submachine gun in an enclosed apartment hallway, the sound would have been a deafening, rapid-fire burst, waking the entire complex. The auditory witness testimony simply did not match the mechanics of the alleged weapon.
Prosecutor Richardson pushed back furiously, reminding the jury that while the match wasn’t microscopically perfect, Garrison had determined that four of the shell casings found at the scene exhibited ejector marks highly consistent with the Sten gun. He urged the jury to look at the totality of the circumstances. The stalking, the threats, the flight, the note, the arsenal. It was not a coincidence.
The jury was sent to deliberate. Despite the profound lack of physical evidence and the entirely inconclusive ballistics, the circumstantial narrative was too powerful to ignore. The jury deliberated for less than two agonizing hours.
On October 23, 2013, the nine-man, three-woman jury returned to the courtroom and delivered a devastating verdict: guilty on all counts, including two counts of first-degree murder.
Two days later, the sentencing phase began. The jury was tasked with deciding whether Hosier would spend the rest of his life in a concrete cell, or if the state should put him to death. It took them only one day to reach a unanimous recommendation. They chose death.
On November 26, 2013, Cole County Circuit Court Judge Patricia Joyce officially sentenced David Hosier to die by lethal injection. She read the sentence with cold, judicial stoicism. David Hosier stood before her, staring straight ahead, showing absolutely no emotion.
It was a trial defined by what was said about the guns and the voicemails. But the true tragedy of the 2013 trial was defined by the silence. The jury was never told the biological truth about the man sitting at the defense table.
The Invisible Defense: Brain Damage on Trial
The legal definition of a fair trial requires that a jury be presented with all relevant mitigating factors before deciding to execute a human being. Mitigation does not excuse the crime, but it provides vital context for the defendant’s mental state, potentially swaying a jury from a death sentence to life without parole.
In 2019, six years after Hosier was sent to death row, his appellate public defender, Amy Bartholow, stood before the seven justices of the Missouri Supreme Court to argue that the 2013 trial was fundamentally, constitutionally broken.
Her argument centered on a catastrophic failure by Hosier’s original defense team. During the crucial sentencing phase of the trial—the phase where the jury decides between life and death—attorneys Janice Zembles and Donald Catlett had completely failed to introduce a single medical expert to testify about David Hosier’s brain.
Bartholow pointed out that the medical records from Audrain Medical Center, documenting the severe stroke Hosier suffered in 2007, were entirely accessible. The records proved, unequivocally, that Hosier suffered from profound, physical brain damage in the exact sectors of the brain responsible for impulse control and emotional regulation. His brain was literally “dead in places.”
The original defense team had technically submitted the thick stack of medical paperwork into the massive pile of evidence given to the jury, but they never called a neurologist, a psychiatrist, or any medical professional to the witness stand to actually explain what those complex medical documents meant. They essentially handed a jury of laypeople a stack of dense, neurological jargon and expected them to diagnose the defendant themselves.
Bartholow argued passionately that if a qualified doctor had taken the stand and explained that Hosier’s biological ability to stop himself from acting on obsessive, violent impulses had been physically destroyed by a blood clot two years before the murders, the jury might have viewed him not as a cold-blooded monster, but as a deeply brain-damaged man incapable of rational restraint. They might have spared his life.
The state, represented by Assistant Attorney General Greg Barnes, aggressively dismissed the argument. Barnes reminded the Supreme Court that the stroke in 2007 could not possibly explain Hosier’s violent domestic battery conviction in 1992, nor his documented threats to kidnap his own children and murder law enforcement officers during his manic episodes in the late 1980s. Barnes characterized the defense’s focus on the brain damage as desperate “Hail Marys” designed to stall a lawful execution.
However, reality outside the courtroom painted a vastly different picture. Hosier’s post-conviction attorney, Jeremy Weiss, tracked down the original jurors from the 2013 trial and interviewed them. Weiss asked them a simple, haunting question: If a doctor had sat on the witness stand and explicitly explained how the brain damage destroyed his impulse control, would it have changed your decision to sentence him to death?
According to Weiss, the jurors’ responses were absolutely chilling. They almost universally answered yes. Had they understood the biology of his broken mind, they would not have sent him to the execution chamber.
Despite this revelation, the legal system relies on procedural rigidity, not retroactive juror regret. In December 2019, the Missouri Supreme Court issued a unanimous 7-0 decision, authored by Judge Paul Wilson. They ruled that Hosier had received adequate legal representation and denied his appeal entirely. Every legal door slammed permanently shut.
But the most tragic irony of the exhaustive appeals process was David Hosier himself. He sat in his cell at the maximum-security Potosi Correctional Center, completely rejecting the efforts of his own legal team. He was disgusted by their strategy. He vehemently instructed his attorneys not to use his father’s tragic line-of-duty death, his military service, his bipolar disorder, or his brain damage to beg for mercy.
He furiously referred to the psychological mitigation strategy as the “boohoo, woe is me” defense. He did not want to be viewed as a broken victim of circumstance. He demanded his lawyers focus exclusively on the complete lack of physical evidence—the missing DNA, the absent fingerprints, the inconclusive ballistics. He wanted to be exonerated based on the facts of the crime scene, not excused because of a broken brain. The legal system ignored his demands, and ultimately, it ignored his appeals.
The Countdown to the Gurney
On February 14, 2024, the Missouri Supreme Court signed the official death warrant, scheduling David Hosier’s execution for June 11.
As the date rapidly approached, Hosier’s physical body began to fail long before the lethal injection could. On May 16, just twenty-six days before his scheduled death, he suffered a massive medical emergency inside the Potosi Correctional Center. He was rushed from his cell to a medical unit, where prison doctors diagnosed him with severe heart failure, specifically atrial fibrillation. His heart was beating irregularly and weakly, causing his legs to swell massively with fluid. The pain was excruciating.
His sister, Barbara Moral, who had spent a decade watching her brother deteriorate inside the concrete walls, expressed deep anguish over the prison’s medical response, questioning why it took a week of agonizing symptoms before they finally moved him to a hospital setting. She reported that he was so weak he could barely walk or string a sentence together.
This medical collapse sparked outrage among anti-death penalty advocates. Reverend Jeff Hood, a spiritual advisor who had counseled David daily and had sat beside six other condemned men in the execution chamber over the previous eighteen months, held a fiery news conference. Staring directly into the cameras, Hood demanded of the state, “How sick does a person have to be to not be executed in the state of Missouri?”
Four days before the execution, Hosier was released back into the prison population. Photographs released to the press showed a frail, hollowed-out shell of the former firefighter. He was confined to a wheelchair, gripping a cane tightly, his skin pale and his breathing labored. Speaking to reporters through a crackling prison phone line, he wheezed through his sentences. Yet, his resolve remained unbroken. “I’m not an angel, I know that,” he whispered. “I’m human, I make mistakes. We all make mistakes.” But he firmly maintained that murder was not one of the mistakes he had made.
In a final, desperate bid to save his life, political leaders intervened. On June 8, United States Representatives Cori Bush and Emanuel Cleaver II sent a passionate letter directly to Missouri Governor Mike Parson. They pleaded for clemency, citing the severe brain damage, the stroke, and the fact that the original jurors had admitted their ignorance regarding his medical condition. “Each of us is more than the worst thing we have ever done,” they wrote. “The same is true for Mr. Hosier.”
Their pleas fell on deaf ears.
On June 10, just twenty-four hours before the execution, Governor Mike Parson released a definitive statement permanently denying the clemency petition. Parson’s words were devoid of sympathy for the condemned man. He focused entirely on the victims, stating that Angela Gilpin had her life stolen simply because Hosier could not accept rejection. Parson condemned Hosier’s lack of remorse and expressed his profound hope that the lethal injection would finally bring closure to the agonizing pain experienced by the Gilpin family.
The Last Sentence
Which brings the story back to the sterile, terrifying silence of the execution chamber in Bonne Terre on June 11, 2024.
The morning of his death, Hosier released a final, haunting public statement to the Associated Press. It was not a plea for forgiveness. It was not a confession to clear his conscience before meeting his maker. It was a confident declaration of his eternal destination. “Now I get to go to heaven,” the statement read. “Don’t cry for me. Just join me when your time comes.”
His spiritual advisor, Reverend Hood, noted that Hosier walked into the execution chamber feeling a profound sense of dignity. He felt that by refusing to confess to a crime he swore he did not commit, and by refusing to let his lawyers use his brain damage as a crutch, he had finally stood up for himself against a system determined to break him.
At 6:11 p.m., the heart that had been failing him for weeks was finally stopped by the pentobarbital.
The execution of David Russell Hosier closed the legal file on the murders of Angela and Rodney Gilpin, but it completely failed to close the moral and judicial wounds surrounding the case.
Angela Gilpin was forty-five. Rodney Gilpin was sixty-one. They were two human beings who spent two decades together, experienced the pain of separation, and bravely chose to try and put their broken marriage back together. They deserved the opportunity to rebuild their lives. Instead, they were slaughtered in a dark hallway, their bodies left tangled on the floor. Angela had done everything society asks a victim of stalking to do. She warned her landlord. She warned the police. She formally begged a judge for a protective order. She predicted her own murder, and the system allowed her to die.
And then, the system took the life of a sixty-nine-year-old man. A boy whose father was murdered in the line of duty. A man whose brain was physically destroyed by a medical stroke. A defendant convicted entirely on circumstantial evidence, inconclusive ballistics, and voicemails, without a single microscopic drop of physical evidence placing him at the scene of the crime.
Did the state of Missouri execute a cunning, obsessive killer who managed to pull off a perfect, forensic-free crime before fleeing with an arsenal of weapons? Or did they strap an innocent, brain-damaged man to a gurney and inject him with poison to close a cold case?
The courts have moved on. The execution chamber has been cleaned. The legal arguments have been permanently silenced. The definitive answer will never be found in a court of law. It now belongs to the endless debate of history, a chilling reminder of the irreversible, terrifying power of the death penalty.
