Federal judge says Alabama can conduct nation’s first execution with nitrogen gas
MONTGOMERY, Ala. — Alabama will be allowed to put an inmate to death with nitrogen gas later this month, a federal judge ruled Wednesday, clearing the way for what would be the nation’s first execution under a new method the inmate’s lawyers criticize as cruel and experimental.
U.S. District Judge R. Austin Huffaker rejected Alabama inmate Kenneth Eugene Smith’s request for a preliminary injunction to stop his scheduled Jan. 25 execution by nitrogen hypoxia. Smith’s attorneys have said Alabama is trying to make Smith the “test subject” for an untried execution method after he survived the state’s previous attempt to put him to death by lethal injection.
Robert Grass, the inmate’s attorney, said his team will appeal the decision but he declined further comment. Alabama Atty. Gen. Steve Marshall’s office was expected to issue a statement Wednesday afternoon. The question of whether the planned execution can ultimately proceed could end up before the U.S. Supreme Court.
The state’s plans call for placing a respirator-type face mask over Smith’s nose and mouth to replace breathable air with nitrogen, causing him to die from lack of oxygen. Three states — Alabama, Mississippi and Oklahoma — have authorized nitrogen hypoxia as an execution method, but no state has attempted its use thus far.
Smith’s attorneys had argued the new protocol is riddled with unknowns and potential problems that violate the constitutional ban on cruel and unusual punishment.
Huffaker acknowledged that execution by nitrogen hypoxia is a new method but noted that lethal injection — now the most common execution method in the country — once was also new. He said that while Smith had shown theoretical risks of pain and suffering under the state’s protocol, those risks do not rise to an unconstitutional violation.
Death penalty: Alabama is seeking to become the first state to execute a death row prisoner by making him breathe pure nitrogen.
“Smith is not guaranteed a painless death. On this record, Smith has not shown, and the court cannot conclude, the Protocol inflicts both cruel and unusual punishment rendering it constitutionally infirm under the prevailing legal framework,” Huffaker wrote in the 48-page ruling.
Huffaker also wrote that there wasn’t enough evidence to find that the protocol “is substantially likely to cause Smith superadded pain short of death or a prolonged death.”
Smith, now 58, was one of two men convicted of the murder-for-hire of a minister’s wife in 1988 that rocked a small north Alabama community. Prosecutors said Smith and the other man were each paid $1,000 to kill Elizabeth Sennett on behalf of her husband, who was deeply in debt and wanted to collect on insurance.
Smith survived the state’s prior attempt to execute him. The Alabama Department of Corrections tried to give Smith a lethal injection in 2022 but called it off when authorities could not connect the two intravenous lines needed to proceed.
The judge’s ruling letting the nitrogen execution plan go forward came after a court hearing in December and legal filings in which attorneys for Smith and Alabama gave diverging descriptions of the risks and humaneness of death from nitrogen gas exposure.
The state attorney general’s office had argued that the deprivation of oxygen would “cause unconsciousness within seconds, and cause death within minutes.” Its court filings compared the new execution method to industrial accidents in which people passed out and died after exposure to nitrogen gas.
Alabama authorities had faced a midnight deadline to begin the execution of a man convicted in the 1988 murder-for-hire slaying of a preacher’s wife.
But Smith’s attorneys noted in court filings that the American Veterinary Medical Assn. wrote in 2020 euthanasia guidelines that nitrogen hypoxia is an acceptable method of euthanasia for pigs but not for other mammals because it could create an “anoxic environment that is distressing for some species.”
Smith’s attorneys also argued that the gas mask, which sits over the nose and mouth, would interfere with Smith’s ability to pray aloud or make a final statement before witnesses in his final moments.
The attorney general’s office called those concerns speculative.
The Alabama prison system agreed to minor changes to settle concerns that Smith’s spiritual advisor would be unable to minister to him before the execution. The state wrote that the spiritual advisor could enter the execution chamber before the mask was placed on Smith’s face to pray with him and anoint him with oil.
Smith’s victim was found dead on March 18, 1988, in the home she shared with her husband Charles Sennett Sr. in Alabama’s Colbert County. The coroner testified that the 45-year-old woman had been stabbed repeatedly. Her husband, then the pastor of the Westside Church of Christ, killed himself when the murder investigation focused on him as a suspect, according to court documents.
Smith’s initial 1989 conviction was overturned on appeal. He was retried and convicted again in 1996. The jury recommended a life sentence by a vote of 11-1, but a judge overrode the recommendation and sentenced Smith to death. Alabama no longer allows a judge to override a jury’s decision on death penalty decisions.
John Forrest Parker, the other man convicted in the case, was executed in 2010.
