The execution of Alan Eugene Miller, a 59-year-old Alabama death row inmate with a documented history of severe mental illness, descended into a harrowing spectacle Thursday evening as the state’s second attempt to 𝓀𝒾𝓁𝓁 him using an untested nitrogen hypoxia method left witnesses describing violent convulsions, desperate gasping, and a prolonged struggle that contradicted official assurances of a peaceful death. Miller was pronounced dead at 6:38 p. m.
at Holman Correctional Facility, nearly 22 minutes after the gas mask was sealed over his face, marking only the second time in U. S. history that nitrogen gas has been used to carry out a death sentence.
His final words, “I didn’t do anything to be in here,” echoed through the chamber before the gas began to flow, a statement that his attorneys and mental health experts say reflected the delusional state that defined his life and his crimes.
The execution unfolded in two distinct phases, according to witness accounts and a transcript of the proceedings obtained by this news organization. At 6:16 p. m.
, the plastic mask was secured, and nitrogen started replacing the oxygen in Miller’s lungs. Within seconds, his body jerked violently against the leather restraints. His chest heaved, his hands twitched, and his face contorted in what observers described as unmistakable signs of panic and pain.
For two full minutes, Miller writhed, his shoulders bucking and his head thrashing. Then came six more minutes of agonizing, shallow breathing—long, desperate attempts to inhale air that was no longer there. His spiritual adviser, Dr.
John Munch, who stood just feet away, later told reporters that Miller’s death was “more anguish than most” and that his face “looked like he was suffering.” The state of Alabama, however, declared the procedure had gone according to plan, calling it “humane and constitutional.”
This was not the first time the state tried to end Miller’s life. In September 2022, prison staff spent nearly three hours attempting to insert an IV line for lethal injection, repeatedly sticking him with needles, digging into his arms, and even hanging him upside down on a gurney in a desperate effort to find a viable vein. They failed, and Miller was returned to his cell bruised, bloodied, and traumatized.
That botched execution led to a federal lawsuit in which Miller argued he should never be subjected to another lethal injection attempt. In response, Alabama agreed to switch him to nitrogen hypoxia—a method never before used in any state at the time—making Miller a human test subject for an experimental execution protocol.
The crimes that landed Miller on death row occurred on August 5, 1999, when he walked into Ferguson Enterprises in Pelham, Alabama, and shot co-worker Lee Holdbrooks, 32, six times, then killed Christopher Yansy, 28, with three fatal rounds. He then drove five miles to a former workplace, Post Air Gas, and shot his ex-supervisor Terry Jarvis, 39, five times. All three men died within an hour.
Miller was arrested later that day after a traffic stop, where he told officers, “They were talking about me.” At trial, evidence showed Miller suffered from severe mental illness, including paranoid delusions that his co-workers were spreading rumors that he was gay. A defense psychiatrist diagnosed him with PTSD with dissociative features, concluding he likely experienced a dissociative episode during the killings and did not fully grasp what he had done.
But Miller’s court-appointed attorney withdrew the insanity plea before trial, telling the jury, “I’m not proud to be representing someone who did what he did.” The jury convicted Miller after just 20 minutes of deliberation. Under Alabama law at the time, a non-unanimous vote—10 for death, two for life—was sufficient to impose a death sentence, and the judge obliged.
Miller’s final meal was a hamburger steak, a baked potato, and French fries—simple, almost childlike comfort food. His final words, repeated just before the gas flowed, were a denial of responsibility: “I didn’t do anything to be in here.” Whether that statement was born of madness or denial, the pain etched on his face during the execution told a different story.
Witnesses from the press leaned forward, watching as his body fought against the restraints, his chest convulsed, and his limbs shook uncontrollably. The room filled with the sound of a man slowly suffocating.
The execution has reignited fierce debate over the death penalty, particularly the use of untested methods and the treatment of mentally ill defendants. Miller’s family had long argued that the system failed him long before he ever touched a gun—that his childhood 𝓪𝓫𝓾𝓼𝓮, his father’s violence, and his untreated paranoia were ignored by a justice system more interested in swift punishment than in understanding the roots of his violence. “The state didn’t just execute a man; it executed a broken mind,” said Dr.
Munch, the spiritual adviser who witnessed the death. “This was not justice. This was an experiment.”
Alabama officials defended the execution, noting that nitrogen hypoxia had been approved by the state legislature and that the U. S. Supreme Court had declined to intervene.
“The sentence was carried out lawfully and humanely,” said a spokesperson for the Alabama Department of Corrections. But the visual evidence from the chamber—the violent shaking, the gasping, the twisted face—contradicts that claim. Medical experts have questioned whether nitrogen hypoxia can ever be truly painless, given that it induces a state of oxygen deprivation that can trigger panic, air hunger, and involuntary muscle contractions before unconsciousness occurs.
Miller becomes the 1,600th person executed in the United States since the death penalty was reinstated in 1977, and only the second to die by nitrogen gas. The first was Kenneth Eugene Smith, executed in Alabama in January 2024, whose death also involved prolonged struggling and gasping. Critics say the state is using death row inmates as guinea pigs to perfect a method that may be more prone to suffering than lethal injection.
“This is not progress; this is regression to a medieval form of execution,” said a spokesperson for the American Civil Liberties Union. “Alabama has now killed two men in a way that looks and sounds like torture.”
For the families of Miller’s victims, the execution brought a long-awaited closure, but also a somber reminder of the violence that shattered their lives. “He took three innocent men from us,” said a relative of Terry Jarvis, speaking outside the prison. “We don’t celebrate his death, but we believe the state did what it had to do.”
Yet even some of those families have expressed discomfort with the method. “I didn’t want to see him suffer,” said another family member. “I just wanted it to be over.”
The execution of Alan Eugene Miller leaves behind a troubling legacy: a man with no prior criminal record, a documented history of severe mental illness, and a dissociative episode at the time of his crimes, who was executed by a method that had never been tested on a human being before this year. His final meal, his final words, and his final moments will be studied by legal scholars, medical ethicists, and human rights advocates for years to come. What happened inside that chamber was not swift or silent.
It was experimental, and it was excruciating. And it raises a question that will not fade with the news cycle: When the state kills a man who is mentally ill, whose life unraveled in delusion and silence, do we call that justice, or just vengeance dressed in protocol?
