Arizona ‘refurbishes’ its gas chamber to prepare for executions, documents reveal

The corrections department has spent more than $2,000 on ingredients to make cyanide gas, the same used in Auschwitz

The state of Arizona is preparing to kill death row inmates using hydrogen cyanide, the same lethal gas that was deployed at Auschwitz.

Documents obtained by the Guardian reveal that Arizona’s department of corrections has spent more than $2,000 in procuring the ingredients to make cyanide gas. The department bought a solid brick of potassium cyanide in December for $1,530.

It also purchased sodium hydroxide pellets and sulfuric acid which are intended to be used to generate the deadly gas. The gas chamber itself, built in 1949 and disused for 22 years, has been dusted off and, according to the department, “refurbished”.

Over the past few months the Republican-controlled state has moved aggressively to restart its deeply flawed execution system. The death penalty has been in abeyance in Arizona for seven years following the gruesomely botched lethal injection of Joseph Wood in 2014.

Last month, the Guardian revealed that Arizona spent a jaw-dropping $1.5m on a batch of pentobarbital in October, a sedative which it now hopes to use as its main lethal injection method.

The Guardian’s documents, obtained through public records requests, show that officials have also gone to considerable lengths to revive the state’s mothballed gas chamber, housed at ASPC-Florence. A series of tests were conducted last August to appraise its “operability”.

Seals on windows and the door were checked to ensure airtightness, and drains cleared of blockage. Water was used in the tests in place of the deadly chemicals, with a smoke grenade ignited to simulate the gas.

Some of the techniques used to test the safety of the chamber were astonishingly primitive, the documents reveal. Prison officials checked for gas seepages with a candle.

The flame of the candle was held up to the sealed windows and door and if its flame remained steady and did not flicker the chamber was deemed to be airtight. In December staff declared the vessel “operationally ready”.

The preparation of cyanide gas executions presents Arizona death row inmates with a Hobson’s choice between two questionable ways to die. Should they opt for the gas chamber, they should be mindful of the last time anybody was gassed by the state.

Walter LaGrand, a German national, was sentenced to death for a 1982 bungled armed bank robbery in which a man was killed. The Tucson Citizen published an eyewitness account of his 1999 execution in which he displayed “agonizing choking and gagging” and took 18 minutes to die.

“The witness room fell silent as a mist of gas rose, much like steam in a shower, and Walter LaGrand became enveloped in a cloud of cyanide vapor,” the Citizen reported. “He began coughing violently – three or four loud hacks – and made a gagging sound before falling forward.”

The newspaper recorded that over many minutes the inmate’s head and arms twitched, and his hands were “red and clenched”.

Should an inmate choose death by lethal injection – the method widely deployed among death penalty states as the supposedly scientific and humane alternative to gas, electric chair or firing squad – they will also find the last time it was used in Arizona it was anything but humane.

Joseph Wood took almost two hours to die when Arizona experimented on him with 15 doses of a then little-used concoction of lethal injection drugs. An eye witness told the Guardian that he counted Wood gasp and gulp 660 times.

In its current rush to restart executions, Arizona has selected two inmates as likely candidates to go first out of a current death row population of 115 people. They are Frank Atwood, 65, sentenced to death for killing an eight-year-old girl, Vicki Lynne Hoskinson, in 1984; and Clarence Dixon, 65, convicted of the 1978 murder of a college student, Deana Bowdoin.

A member of Atwood’s legal team, Joseph Perkovich of Phillips Black, told the Guardian that it was improper for the state to be hurrying towards setting an execution date when the pandemic had impeded investigation into his client’s possible innocence for more than a year. As for Atwood’s choice between lethal injection or gas, Perkovich said: “Neither option is tenable.”

The attorney pointed out that there is a discrepancy between the potassium cyanide that has been obtained by the corrections department and the state’s execution protocol which stipulates that sodium cyanide must be used. “This is not a small detail – the specific compound is vitally important,” he said.

Perkovich added that “Frank Atwood is prepared to die. He is a man of Greek Orthodox faith and is preparing for this moment. But he does not want to be tortured and subjected to a botched execution.”

Inmates who choose the gas chamber are strapped into a chair in the centre of the vessel. Coloured levers are then used to drop the sodium cyanide into a pot of sulfuric acid under the chair, releasing the deadly hydrogen cyanide into the air.

Once the prisoner is dead, the gas is neutralized with ammonia until the chamber is safe to enter. “As a precautionary method,” the death chamber protocol says, “it is recommended that the team removing the body wear gas masks and rubber gloves and that the hair of the deceased inmate be ruffled in order to allow any residually trapped gas to escape.”

The documents record how prison staff engaged in role play during last year’s tests. Guards acted out as inmates who resisted going to their death, screaming: “This is murder”, “I’m innocent”, “You’re putting me down like an animal”, and “This is against everything America stands for”.

Despite Arizona’s best efforts to present its gas chamber as a reputable institution, the horrors of the past hang heavily over it. The Nazis used hydrogen cyanide under the trade name Zyklon B to kill more than 1 million people in gas chambers in Auschwitz and other extermination camps.

Robert Dunham, executive director of the Death Penalty Information Center, said: “You have to wonder what Arizona was thinking in believing that in 2021 it is acceptable to execute people in a gas chamber with cyanide gas. Did they have anybody study the history of the Holocaust?”

Death penalty options expanded in proposed Arizona bills

PHOENIX — Arizona lawmakers advanced proposals on Feb. 19, 2026, that would expand execution options for death row inmates to include firing squads and lethal gas, amid ongoing challenges with lethal injection and concerns over carrying out capital sentences. The measures, sponsored by Sen. Kevin Payne, R-Peoria, cleared a Senate committee with a party-line vote. They aim to give condemned inmates more choices while mandating firing squad executions for those convicted of murdering law enforcement officers. Senate Concurrent Resolution 1049 proposes a constitutional amendment that Arizona voters would decide in November. If approved, it would allow defendants sentenced to death to select from three methods: firing squad, lethal injection (intravenous administration of lethal substances) or lethal gas. Lethal injection would remain the default if no choice is made.

India | POCSO Court awards death penalty to UP couple for sexual exploitation of 33 children

A special court in Uttar Pradesh’s Banda on Friday sentenced a former Junior Engineer (JE) of the Irrigation Department and his wife to death for the sexual exploitation of 33 minor boys — some as young as three — over a decade, officials said. The POCSO court termed the crimes as “rarest of rare” and held Ram Bhawan and his wife Durgawati guilty of systematically abusing children between 2010 and 2020 and producing child sexual abuse material. Convicting the duo under provisions of the Indian Penal Code and the Protection of Children from Sexual Offences (POCSO) Act, the court sentenced them to death for offences including aggravated penetrative sexual assault, using a child for pornographic purposes, storage of pornographic material involving children, and abetment and criminal conspiracy, they said.

Oklahoma Ends Indefinite Death Row Solitary Confinement

Every year, thousands of prisoners in the U.S. are placed in solitary confinement, where they endure isolation, abuse, and mental suffering . This practice might soon become rarer for some inmates in Oklahoma, thanks to the efforts of activists in the state. Earlier this month, the American Civil Liberties Union (ACLU) of Oklahoma announced that the Oklahoma State Penitentiary in McAlester had ended the practice of indefinite solitary confinement for "the vast majority" of death row prisoners.

Alabama provides the greatest arguments against the death penalty

I have seen three executions. I hope I never see a fourth. Capital punishment is violence. But the state does all it can to conceal that fact. The viewing areas outside the death chamber are still and silent. Bright light floods the small room where people die. The warden pronouncing the sentence speaks in clipped, measured tones, saying no more than needed. You’re expected to view the act as a bloodless execution of justice.

Florida executes Melvin Trotter

The execution of Melvin Trotter for the murder of 70-year-old Virgie Langford in 1986 comes as Supreme Court Justice Sonia Sotomayor questions Florida's 'deeply troubling' lethal injection record. Florida has executed its second inmate of the year even as a Supreme Court justice questioned the state's “deeply troubling" record on lethal injections and how it "shrouds its executions in secrecy."  Melvin Trotter, 65, was executed by lethal injection on Tuesday, Feb. 24, for the 1986 murder of 70-year-old Virgie Langford, a mother of 4 who was on the verge of retirement when she was stabbed to death in the corner grocery store that she owned for five decades. Trotter was pronounced dead at 6:15 p.m. ET. 

Sudanese Courts Sentence 2 Women to Death by Stoning for Adultery Despite International Obligations

Two Sudanese women have been sentenced to death by stoning in separate cases in Sudan, raising serious concerns about Sudan’s compliance with its international human rights obligations, particularly following its ratification of the United Nations Convention against Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment (UNCAT).

Florida | Governor DeSantis signs death warrant in 2008 murder case

TALLAHASSEE, Fla. — Governor Ron DeSantis has signed a death warrant for Michael L. King, setting an execution date of March 17, 2026, at 6 p.m. King was convicted and sentenced to death for the 2008 kidnapping, sexual battery and murder of Denise Amber Lee, a 21-year-old North Port mother. On January 17, 2008, Michael Lee King abducted 21-year-old Denise Amber Lee from her North Port home by forcing her into his green Chevrolet Camaro. He drove her around while she was bound, including to his cousin's house to borrow tools like a shovel.  King took her to his home, where he sexually battered her, then placed her in the backseat of his car. Later that evening, he drove to a remote area, shot her in the face, and buried her nude body in a shallow grave. Her remains were discovered two days later. During the crime, multiple 9-1-1 calls were made, but communication breakdowns between emergency dispatch centers delayed the response.  The case drew national attention and prompted w...

Japan | High court rejects retrial appeal over 1992 Fukuoka child murder

The Fukuoka High Court rejected an appeal on Monday for a retrial for the 1992 murder of two 7-year-old girls in the city of Iizuka in Fukuoka Prefecture, for which a death row convict was executed. The defense plans to file a special appeal with the Supreme Court against the decision.  In what's known as the Iizuka incident, despite the assertion of his innocence, Michitoshi Kuma's death sentence became final in 2006 based on DNA test results and eyewitness accounts. He was executed at the age of 70 in 2008.  The defendant's side submitted in the second round of its retrial request a woman's testimony as new evidence. 

Louisiana Supreme Court Unanimously Sides with Two Death-Sentenced Prisoners Targeted with Premature Execution Warrants

When Louisiana Governor Jeff Landry and Attorney General Liz Murrill took office in January 2024, they moved aggres­sive­ly to restart exe­cu­tions in the state. Gov. Landry signed bills that autho­rized nitro­gen suf­fo­ca­tion and elec­tro­cu­tion as exe­cu­tion meth­ods, increased his own pow­er over the state cap­i­tal defense sys­tem, and lim­it­ed post-con­vic­tion appeals , while AG Murrill moved to take over cap­i­tal appeal chal­lenges from local dis­trict attor­neys. In March 2025, the state con­duct­ed its first exe­cu­tion in 15 years.
