Alan Eugene Miller was executed by nitrogen hypoxia Thursday evening at the William C. Holman Correctional Facility in Atmore, Alabama, ending a 25-year legal battle over a triple murder that left three families shattered and raised profound questions about mental illness and capital punishment.
The 59-year-old former delivery driver, convicted of killing three men in a 1999 rampage fueled by paranoid delusions, was pronounced dead at 6:38 p. m. local time after the state’s second use of the untested nitrogen gas method.
Witnesses reported that Miller convulsed and gasped for several minutes before losing consciousness.
Miller’s final words, spoken just before a mask was sealed over his face, were a stark denial of his guilt. “I didn’t do anything to be in here,” he said, according to those present. The comment echoed his long-standing claim that he was innocent, despite overwhelming evidence that he shot three coworkers in cold blood.
The execution proceeded after a series of legal challenges failed, including arguments that the nitrogen hypoxia protocol was cruel and unusual following a similarly botched execution in January. Alabama Attorney General Steve Marshall described the punishment as justice finally served for the victims: Lee Holbrooks, Christopher Yancey, and Terry Jarvis.
Governor Kay Ivey said in a statement that “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.”
But critics and Miller’s spiritual advisor painted a different picture. Dr. John Munch, a physician and pastor who was in the execution chamber, told reporters that Miller’s violent shaking and labored breathing indicated suffering.
“We don’t see people jerking around like that while they’re dying normally,” Munch said. “His face was twisted and he looked like he was suffering.”
The Alabama Department of Corrections Commissioner John Hamm defended the procedure, saying the movements were expected and consistent with the protocol. “Everything went according to plan and according to our protocol,” Hamm stated at a press conference after the execution.
Miller’s case had become one of the most legally contentious in modern American history, marked by a split jury recommendation of death, a judge’s override that bypassed that division, and a failed lethal injection attempt in 2022 that left him strapped and bleeding for 20 minutes.
On August 5, 1999, Miller walked into the Ferguson Enterprises office in Pelham, Alabama, armed with a .40 caliber Glock pistol. He told the vice president of operations, “I’m tired of people starting rumors on me,” before methodically shooting three coworkers he believed were spreading false rumors that he was gay.
Lee Holbrooks, 32, was shot in the chest and head, then crawled 25 feet toward the exit while bleeding profusely. Miller followed him and delivered a final, close-range shot to the head as Holbrooks looked up. Christopher Yancey, 28, was paralyzed by a bullet that severed his spine, then shot again while slumped under his desk.
Terry Jarvis, 39, was shot five times behind the counter of his workplace.
Miller drove to a second location, shot Jarvis, then was arrested later that day after a brief struggle. Inside his truck, police found the Glock with one round in the chamber and 11 more in the magazine. Ballistics confirmed the gun was used in both attacks.
At trial, defense attorneys argued that Miller suffered from a delusional disorder, a condition where a person holds fixed false beliefs that cannot be shaken by evidence. A forensic psychiatrist testified that Miller’s belief about the rumors was clinically real to him, but under Alabama law, the insanity defense required proof that he could not distinguish right from wrong. That threshold was not met.
The penalty phase was notably brief. Miller’s court-appointed attorney presented almost no mitigating evidence—no testimony about the extreme 𝓪𝓫𝓾𝓼𝓮 Miller endured from his father, no records of his family’s multi-generational mental illness, no character witnesses. The jury deliberated only three hours, returning a 10 to 2 vote in favor of death.
At the time, Alabama was the only state that allowed a judge to override a non-unanimous jury recommendation for death.
The trial judge acknowledged the difficulty of the decision before imposing the death sentence. Miller spent the next 24 years on death row, his appeals repeatedly denied. Courts cited the overwhelming evidence and the brutality of the crimes, while acknowledging his mental illness but concluding it did not change the outcome.
In 2018, Alabama authorized nitrogen hypoxia as a new execution method, and Miller selected it. But the state later attempted to execute him by lethal injection in September 2022. That attempt failed when prison staff could not establish intravenous access.
Miller alleged he was left strapped to the gurney, inverted and bleeding, for 20 minutes. The state later settled a lawsuit, agreeing to use nitrogen hypoxia.
The first human execution by nitrogen hypoxia took place on January 25, 2024, when Kenneth Eugene Smith was put to death. Witnesses described Smith convulsing for two minutes and gasping for several more. State officials claimed the method was humane.
Miller’s legal team argued the same unmodified protocol would cause suffering, but courts rejected their challenge.
On Thursday, the process unfolded similarly. Miller began shaking almost immediately after the nitrogen gas began flowing at 6:16 p. m.
His body trembled for approximately two minutes, his arms pulling against restraints. Then came six minutes of intermittent gasping—deep, labored breaths as his body fought for oxygen. After eight minutes total, he became still.
The gas continued for 15 minutes.
Miller’s last meal consisted of a hamburger steak, a baked potato, and French fries. He had nine visitors that day, including family members who maintained their support for him. His spiritual advisor, Dr.
John Munch, remained with him throughout.
The execution made Miller the 1,600th person executed in the United States since capital punishment resumed in 1976. He was one of five inmates put to death in the same week, the highest weekly total since July 2000.
Terra Barnes, the widow of victim Lee Holbrooks, said before the execution that it had taken far too long to reach this point. “I feel that it has taken way too long to get here,” she said. For the families of the victims, the execution closed a quarter-century of waiting for finality.
But the debate over the method will likely continue. Critics argue that nitrogen hypoxia has not been properly tested and that the visible suffering of both Smith and Miller indicates a failure to deliver a humane death. Amnesty International and other human rights groups have condemned the execution, calling it a violation of the prohibition on cruel and unusual punishment.
Miller’s final words, “I didn’t do anything to be in here,” will be remembered as a defiant proclamation from a man who, according to his own attorney, genuinely believed the rumors were real. Whether that belief negates responsibility is a question that divided the jury, the courts, and the public for 25 years.
Thursday night in Atmore, Alabama, that question was answered not by a court, but by a mask, a flow of gas, and a moment when the room fell silent. Three men died in 1999. A fourth died last night.
And somewhere, the families of Lee Holbrooks, Christopher Yancey, and Terry Jarvis continued to live with a loss that no execution can restore.
