The Nitrogen Hypoxia Execution of Alan Eugene Miller: Delusional Murders, a 10-2 Jury, and a Death That Sparked Debate
On September 26, 2024, Alan Eugene Miller was executed by nitrogen hypoxia at the William C. Holman Correctional Facility in Atmore, Alabama. He had waited more than twenty-five years for this moment. Strapped to a gurney with a mask sealed over his face, he spoke his final words just before the gas began to flow: “I didn’t do anything to be in here.” He repeated the sentence, then asked the people who had come to witness his death to take care of someone whose name was inaudible through the mask.
This is the full story of Alan Eugene Miller — who he was, the delusional beliefs that drove him to kill three men on a single August morning in 1999, the trial that ended with a split jury and a judge’s override, the years of appeals, the botched lethal-injection attempt that nearly killed him in 2022, and the controversial nitrogen execution that followed. It is a story of mental illness, justice delayed, and a method of execution that divided everyone who watched it.
This one is heavy. Stay with it.
A Life That Looked Ordinary — Until It Wasn’t
Alan Eugene Miller was born on January 20, 1965, in Alabama. By 1999 he was thirty-four years old, with no criminal record and no history of violence known to the public. He worked as a delivery truck driver at Ferguson Enterprises, a heating-and-air-conditioning distributor in Pelham, Alabama. He showed up, did his job, and went home.
Beneath that ordinary surface, however, something had been quietly unraveling for years. Miller’s family carried a documented, multi-generational history of serious mental illness. He himself had suffered extreme physical and emotional abuse at the hands of his father during childhood. That trauma, layered onto an already fragile mind, set the stage for what came next.
At some point Miller became convinced that his co-workers were spreading rumors about him — specifically that he was gay. There was no evidence this was true. In his mind, however, the belief was fixed and unshakable. A forensic psychiatrist would later diagnose him with delusional disorder: a condition in which a person holds a false belief so firmly that no amount of reasoning or contrary evidence can dislodge it. Miller was not faking it. He genuinely believed these men were destroying his reputation, and in his fractured state he decided to act.
The Morning of August 5, 1999
It was a Thursday, just after 7:00 a.m. in Pelham, Alabama. Co-workers were pulling into the Ferguson Enterprises parking lot with coffee cups and small talk. Johnny Cobb, vice president of operations, arrived and immediately sensed something wrong. He heard screaming. He opened the front door.
Alan Miller walked straight toward him holding a .40-caliber Glock pistol. “I’m tired of people starting rumors on me,” Miller said. Cobb pleaded with him to put the gun down. Miller told him to get out of the way. Cobb ran.
What happened inside the building over the next few minutes was methodical and unrelenting.
Lee Holdbrooks, 32, was the first victim. Miller shot him in the chest and the head. The wounds were devastating but not immediately fatal. Holdbrooks, still alive and terrified, crawled twenty-five feet down a hallway, dragging himself toward the exit and leaving a long trail of blood. Miller did not leave. He waited. When Holdbrooks could crawl no farther, Miller walked up, stood over him, and fired one final shot into his head at close range. Holdbrooks was looking up at his killer when the trigger was pulled. He had been shot six times in total.
Christopher Yansy, 28, was in his office. Miller shot him once; the bullet tore through his groin and into his spine, paralyzing him instantly. Yansy was alive and fully conscious but could not move. His cell phone lay just inches from his hand — unreachable. Miller walked over, stooped down, looked into Yansy’s eyes, and fired two more times. Yansy was shot three times total.
Miller then left Ferguson Enterprises, got into his truck, and drove five miles to Post Air Gas, a business where he had previously worked. His former supervisor, Terry Jarvis, 39, was behind the sales counter. Miller shot Jarvis in the chest and abdomen. Jarvis went down, severely wounded but still alive. Miller walked behind the counter, stood over him, and fired again. Jarvis was shot five times.
Three men. Two locations. Minutes. Miller got back in his truck and drove away.
Later that same day a police officer spotted his vehicle on the side of an Alabama highway and pulled him over. When officers tried to take him into custody, Miller resisted violently. It took four officers and four separate pairs of handcuffs to subdue him. Inside the truck sat the .40-caliber Glock with one round still in the chamber, eleven more in the magazine, and an empty second magazine on the passenger seat. Ballistics matched every shell casing from both scenes.
Trial, Split Verdict, and Judicial Override
Miller was charged with three counts of capital murder. The 2000 trial produced overwhelming evidence: eyewitnesses, ballistics, and Miller’s own words spoken while holding the loaded gun. His defense team argued mental illness. A forensic psychiatrist testified that Miller suffered from delusional disorder — the rumors were clinically real to him even though they were false.
Under Alabama law, however, the insanity defense requires that the defendant could not distinguish right from wrong. The psychiatrist acknowledged that Miller’s condition, while severe, did not meet that strict legal threshold. The defense withdrew the insanity plea before it reached the jury.
The penalty phase was strikingly brief. Miller’s court-appointed attorneys presented almost nothing — just a few sentences from one psychiatrist. No evidence of his childhood abuse. No testimony about the family’s multi-generational mental illness. No character witnesses. Nothing more.
The jury deliberated for three hours and returned a 10-to-2 vote in favor of death. In most states that split verdict would have automatically meant life without parole. Alabama was the only state in the country at the time that allowed a judge to override a non-unanimous jury recommendation. The trial judge called it “probably the most difficult sentence I’ve ever had to consider,” then sentenced Alan Eugene Miller to death by electrocution on August 24, 2000.
Twenty-Five Years of Appeals and a Botched Attempt
Miller’s appeals centered on ineffective assistance of counsel — the near-total failure to present mitigating evidence — and his documented mental illness. Courts reviewed the claims and denied them. He remained at Holman Correctional Facility while the calendar turned.
In 2018 Alabama authorized nitrogen hypoxia as a new execution method. Inmates could choose their preferred method. Miller chose nitrogen hypoxia. The state acknowledged the choice but scheduled him for lethal injection anyway.
On September 22, 2022, Miller was strapped down for lethal injection. Prison staff could not find usable veins. The execution warrant expired at midnight and the attempt was called off. Miller later alleged that staff left him strapped upside down on the gurney, bleeding for twenty minutes. His attorneys filed a federal lawsuit claiming cruel and unusual punishment. By November 2022 the state agreed in a legal settlement: Alan Miller would not be executed by lethal injection. He would die by the nitrogen method he had chosen four years earlier.
On January 25, 2024, Kenneth Eugene Smith became the first person in history executed by nitrogen hypoxia. Witnesses described several minutes of consciousness followed by shaking, convulsing, and deep, labored gasping. State officials had promised the process would be swift and peaceful. Many who watched said it was neither.
Miller’s attorneys challenged the unmodified protocol, citing Smith’s execution as proof of likely suffering. Courts denied the challenge. The execution date was set for September 26, 2024.
The Final Day
That morning Miller ate his last meal: hamburger steak, a baked potato, and French fries. He had nine visitors — family members who had stood by him for twenty-five years. He met with his spiritual adviser, John Munch, a pastor who was also a physician.
In the evening Miller was taken to the execution chamber. He was strapped to the gurney. A mask was fitted over his face from forehead to chin. Witnesses from the victims’ families, officials, media, and Miller’s supporters took their places on opposite sides of the glass.
At 6:16 p.m. Alabama Attorney General Steve Marshall cleared the execution to begin. The nitrogen gas flowed.
Miller began to shake almost immediately. His body trembled against the restraints for approximately two minutes. The shaking slowed, then came six minutes of intermittent gasping — large, desperate gulps of air as his body fought for oxygen it could not find. For a total of about eight minutes witnesses watched visible distress. The nitrogen continued for fifteen minutes. At 6:38 p.m. Alan Eugene Miller was pronounced dead. He was fifty-nine years old and the 1,600th person executed in the United States since 1976. He was also the fifth execution in the country in a single week — the most in one week since July 2000.
Inside the chamber, spiritual adviser John Munch saw suffering. “We don’t see people jerking around like that while they’re dying normally,” he said afterward. “His face was twisted and he looked like he was suffering.”
Alabama Department of Corrections Commissioner John Ham told reporters the movements were “nothing that we did not expect” and that “everything went according to plan and according to our protocol.”
The Voices Left Behind
Terra Barnes, widow of Lee Holdbrooks, said before the execution: “I feel that it has taken way too long to get here.”
Governor Kay Ivey issued a statement: “Just as Alan Miller cowardly fled after he maliciously committed three calculated murders in 1999, he has attempted to escape justice for two decades. Tonight, justice was finally served for these three victims.”
Three families had waited twenty-five years. Lee Holdbrooks, 32, never made it out of that hallway. Christopher Yansy, 28, never reached his phone. Terry Jarvis, 39, never stood up from behind the counter. They were not symbols in a legal debate. They were husbands, fathers, sons, and co-workers whose ordinary morning became their last.
The Questions That Remain
There are no clean answers here. A man with a documented delusional disorder and a lifetime of untreated trauma walked into two workplaces and ended three lives. A jury split 10-2. A judge overrode them. The state botched one execution attempt, then used an untested method on the next. Witnesses described visible suffering; officials called it protocol.
When a person is executed by a method that witnesses describe as visibly painful — using a protocol that had never been used on a human being before Kenneth Smith and was never properly tested on Miller — does that constitute justice? Or does it complicate the very thing it was meant to deliver?
Three men never came home on August 5, 1999. Twenty-five years later, their killer closed his eyes for the last time on a gurney in Atmore, Alabama. Somewhere in Alabama, a widow finally exhaled.
