Alabama modifies execution chamber for gas executions involving nitrogen hypoxia

Alabama is actively modifying its execution chamber to kill prisoners via nitrogen hypoxia, an untested method that would asphyxiate the condemned through a gas chamber or gas mask.

A federal judge last month ordered the Alabama Department of Corrections to provide information about the hypoxia protocol in an ongoing lawsuit filed by a man petitioning the court to have his spiritual advisor present at his execution.

"The ADOC is nearing completion of the initial physical build for the nitrogen hypoxia system and its safety measures. Once the build is completed, a safety expert will make a site visit to evaluate the system and look for any points of concern that need to be addressed," Alabama Attorney General Steve Marshall said in a Tuesday court filing. 

ADOC on Wednesday declined to answer a number of questions regarding the "physical build" referenced in court documents, including whether it intends to use a gas chamber or a gas mask to administer an execution method that has yet to be tested on human beings. 

"The ADOC’s nitrogen hypoxia execution protocol is still under development, and the physical building modifications to the execution chamber are still in process," the department said in a Wednesday statement. "Due to the fact those two items are not yet in a finalized state and potential security concerns exist, that is all we are able to share at this time."

Alabama passed nitrogen hypoxia legislation in 2018, one of only three states to legalize the method of execution. In theory, a condemned person would inhale pure nitrogen, which would asphyxiate them. 

The legislation, which proponents argued offered a more humane method of execution, effectively ended an ongoing lawsuit over lethal injection in Alabama. The legislation provided people incarcerated on death row a short window in 2018 to opt in to the method. 

But the new law codified a largely hypothetical method of execution. The method has never been tested on humans, and much of the scientific record on the subject comes from veterinary science or hazard investigations, where humans accidentally died in industrial accidents or similar situations. 

In Oklahoma, nitrogen hypoxia executions have technically been legal since 2015, but  last year the state said it would revert to lethal injections. In 2019, The Oklahoman reported multiple manufacturers declined to be involved in the execution process, with at least seven companies declining to sell the necessary "gas delivery device."

"The big issue with nitrogen hypoxia is it is experimental," said Robert Dunham, director of the Death Penalty Information Center. "We just have no idea whether it's going to work the way its proponents say it will. If it does, then there may be a viable alternative to lethal injection. If it doesn't, it may be just another method that was advertised as being humane that turns out not to be. It's completely unethical to experimentally kill someone, so we won't know. ... Nobody knows, nobody has indicated how its going to be carried out, though I suspect the death mask is more likely than a gas chamber. There was never any indication that Oklahoma intended to construct a gas chamber."


Multiple pharmaceutical companies have blocked purchases of lethal injection drugs in recent years amid growing opposition to the death penalty, leading some states to revert to alternate methods. 

New legislation in South Carolina resurrected the firing squad, though the state hasn't killed a prisoner in a decade, according the NPR. 

A Guardian investigation found Arizona recently purchased materials to kill condemned prisoners with cyanide gas, the same method used at the Auschwitz concentration camp during World War II. 

Arizona has "refurbished" an old gas chamber for the executions. Like Alabama, Arizona prisoners can choose between lethal injection or the gas chamber, though executions have been halted in the state for nearly a decade after a botched injection attempt.

Laura Kelly to reject them.

Idaho will soon turn to firing squad executions. Police will pull the triggers

Trained members of Idaho law enforcement with demonstrated firearms proficiency are expected to fill slots for carrying out the death penalty by firing squad as the state prison system transitions to the controversial execution method next month.  Six volunteers certified for no less than three years apiece through Peace Officer Standards and Training, or POST, will be recruited to ensure the Idaho Department of Correction is ready to comply with a state law that prioritizes shooting prisoners to death over lethal injection starting July 1.  No one on the team may have faced disciplinary action over firearms, use of force, or related conduct over the prior year, according to new execution protocols the prison system released this week. 

SCOTUS: Alabama can’t execute Jeffery Lee by nitrogen; Thursday execution called off

After a week of legal volleyball, Alabama death row inmate Jeffery Lee’s execution—scheduled for Thursday evening—was called off after federal courts called the state’s nitrogen gas execution method “likely unconstitutional.” The state took the fight to the U.S. Supreme Court, hoping Lee could still be put to death tonight.  In an order issued at 8:10 p.m., the U.S. Supreme Court ordered that it would not lift a ban on Alabama executing Lee via nitrogen . In a short court order, the justices denied Alabama’s motion to go ahead with the execution.  Associate Justices Clarence Thomas, Samuel Alito, and Neil Gorsuch would have granted the appeal and let the execution proceed, according to the order. 

Alabama | Judge bars nitrogen gas execution, says method is unconstitutionally cruel

MONTGOMERY, Ala. -- A federal judge on Tuesday permanently blocked Alabama from executing an inmate with nitrogen gas after declaring it violates the ban on cruel and unusual punishment. U.S. District Judge Emily Marks issued the ruling hours after an appeals court reversed her initial finding that the method was constitutional. Marks permanently enjoined the state from executing Jeffrey Lee, 49, by nitrogen gas. He was scheduled to be executed Thursday. The decision, for now, blocks the use of the controversial new execution method that the state has championed since 2024, but the issue will likely end up before the U.S. Supreme Court.

With nitrogen gas blocked, Alabama seeks to execute inmate by lethal injection

Jeffery Lee, who successfully challenged his scheduled Thursday execution by nitrogen gas, argued that execution by firing squad would be less painful. The Alabama Attorney General’s Office Friday sought to put an Alabama death row inmate to death by lethal injection a day after the U.S. Supreme Court rebuffed the state’s attempt to execute him by nitrogen gas. In a filing with the Alabama Supreme Court Friday afternoon, the state sought an expedited motion to set a new execution date for Jeffery Lee, 49. The state said that with a permanent injunction in place against nitrogen gas, the method by which the state intended to execute Lee on Thursday, it could execute him by lethal injection or the electric chair.

20 Minutes to Death: Witness to the Last Execution in France

The following document is a firsthand account of the final moments of Hamida Djandoubi, a convicted murderer executed by guillotine at Marseille’s Baumettes Prison on September 10, 1977. The record—dated September 9—was written by Monique Mabelly, a judge appointed by the state to witness the proceedings. Djandoubi’s execution would ultimately be the last carried out in France before capital punishment was abolished in 1981. At the time, President Valéry Giscard d'Estaing—who had publicly voiced his "deep aversion to the death penalty" prior to his election—rejected Djandoubi’s appeal for clemency. Choosing to let "justice take its course," the President allowed the execution to proceed, just as he had in two previous cases during his term:   Christian Ranucci , executed on July 28, 1976 and Jérôme Carrein , executed on June 23, 1977. Hamida Djandoubi , a Tunisian national, was sentenced to death for killing his former lover, Elisabeth Bousquet. He was execu...

New Mississippi billboard warns criminals: ‘Firing squad is legal’

DESOTO COUNTY, Miss. (WREG) — A billboard standing on Interstate 55 southbound as you cross the Tennessee state line and enter Mississippi from Memphis is sending a grim message to those coming into the state. DeSoto County District Attorney Matthew Barton recently announced the new billboard campaign, which features the sign reading, “WELCOME TO MISSISSIPPI. WHERE THE FIRING SQUAD IS LEGAL. THINK TWICE.” It references Mississippi’s law permitting execution by firing squad under certain circumstances for inmates sentenced to death. Barton says this campaign is aimed at deterring violent crime and sends a direct message to criminals entering Mississippi.

US | Army lays groundwork for death row executions if Trump gives approval

The Army is preparing to carry out the executions of the military's four death-row inmates if ordered to do so by the president, according to an internal planning document reviewed by ABC News. If carried out, it would mark the first time the military executed convicted American inmates in more than a half-century The plan, dubbed "Operation Resolute Justice" and issued internally in February, directs Army officials to coordinate with the Federal Bureau of Prisons to transfer condemned prisoners from the U.S. Disciplinary Barracks at Fort Leavenworth, Kansas, to the federal execution facility in Terre Haute, Indiana, where the Justice Department carried out a series of non-military federal executions during President Donald Trump's first term.

Texas | Tanner Horner now incarcerated at the Polunsky Unit

Convicted child killer Tanner Horner has now taken up residence in one of the most brutal death row prisons after being sentenced to die by a Texas jury last month. Horner is incarcerated at the Polunsky Unit, an infamously restrictive prison outside Houston where the state's death row inmates are housed in an all-solitary confinement wing and spend at least 22 hours a day in their 60-square-foot cells. The former FedEx deliveryman, 34, was booked at the notorious prison on May 5 within hours of being sentenced for the gruesome murder of Athena Strand, 7, whom he admitted strangling while delivering a Christmas gift to her home in November 2022.

Thomas, Alito and Gorsuch wanted an execution that a Trump judge deemed illegal

The Supreme Court these days is generally in the business of helping executions go forward. But on Thursday night, the court did something notable: It told Alabama no. Even then, the court wasn't unanimous. Justices Clarence Thomas, Samuel Alito and Neil Gorsuch dissented from the refusal to let the nitrogen gas execution of Jeffery Lee proceed. What prompted the rare rejection? In line with the typical shadow docket practice, the court didn't explain itself. Nor did the dissenters, who merely noted their disagreement. But a deeper look at the case helps us understand why a majority of the court was unwilling to help the state this time.
