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?”

Florida | Former warden recalls botched electrocution that left him battling PTSD for 13 years and turned him into an abolitionist

Ron McAndrew anticipated it would be just another standard execution. He had been assigned to carry out the death of Cuban refugee Pedro Medina via electric chair within the confines of Florida State Prison. Fifteen years had passed since Medina's conviction for the murder of 52-year-old Dorothy James, and McAndrew's responsibility was to oversee the administration of lethal electrical currents to his brain. Having already supervised two previous executions using the identical procedure and raised in a community that strongly supported capital punishment, he expected a swift conclusion with justice delivered.

North Korea | 'I was only 9': North Korean defector recalls childhood memory of public execution

Kim Eun-joo was 9 years old when her teacher stopped their lesson and told the class to follow her outside. The children were marched to a public execution ground in North Korea. “I would cry even when our family dog died,” Kim said in a recent interview with The Korea Times. “But the first time I watched humans killing a human, I had no words for what I was feeling. It was the most brutal scene I have ever seen, in any movie or in real life.” The memory has stayed with her ever since. Now a human rights advocate after defecting from North Korea, Kim recently brought that childhood scene to the 9th World Congress Against the Death Penalty in Paris, where North Korea’s use of public executions and capital punishment was officially placed on the agenda for the first time.

USA | What happens in the final weeks before an execution? These reporters were inside the room.

The journalists behind ‘The Last 12 Weeks’ earned extraordinary access to a death penalty defense team—and faced difficult ethical choices Many defense lawyers are naturally cagey. They work in a pressure cooker, protecting their clients’ rights while fighting for the best possible outcome. And arguably, the stakes can’t get any higher than trying to save a client’s life. So no, defense lawyers don’t usually invite journalists into strategy meetings. But that’s what happened when Marshall Project reporter Maurice Chammah and Serial Productions senior producer Alvin Melathe spent the final few months before a Texas execution embedded with a capital defense team.

19 July 1943 | Auschwitz's Largest Public Hanging: 12 Polish Prisoners Executed in Escape Reprisal

OSWIECIM, Poland — The SS carried out the largest public hanging in Auschwitz history on July 19, 1943, executing 12 Polish prisoners before other inmates as collective punishment for escapes and civilian contacts. The victims, all from the camp’s surveyors’ labor unit, were hanged on gallows built in front of the camp kitchen during an Auschwitz I roll call. The SS orchestrated this reprisal following prisoner escapes from the surveyors’ detail and unauthorized communication between inmates and civilians. Camp authorities used the recent escapes as a pretext to impose collective punishment.

Idaho | How Bryan Kohberger’s Guilty Plea Move Could Be His Death Sentence

If Bryan Kohberger successfully withdraws his guilty plea and goes to trial for the murders of four University of Idaho students, it could lead to him being sentenced to death, experts told Newsweek . Kohberger, 31, filed a handwritten petition on Monday from the Idaho Maximum Security Penitentiary, where he is serving four consecutive life sentences for the murders of Kaylee Goncalves, Ethan Chapin, Xana Kernodle and Madison Mogen in a rental home near the university's campus in Moscow, Idaho, in 2022. Kohberger pleaded guilty to the fatal stabbings just over a year ago, a month before jury selection was set to start.
