Arizona | Death Row Inmate Frank Atwood requests execution using nitrogen instead of cyanide gas

Death row prisoner Frank Atwood is requesting the state execute him in the gas chamber, but with nitrogen gas, as opposed to the cyanide specified in the Arizona Department of Corrections protocols.

Atwood is scheduled to be executed on June 8. He was sentenced to death in Pima County in 1987 for the murder of an 8-year-old girl, Vicki Lynne Hoskinson.

Because Atwood’s crimes occurred before the gas chamber was outlawed in Arizona in 1992, he has a choice between death by lethal gas or lethal injection.


State law requires that Atwood choose a method of execution 20 days prior to the execution, which leaves Atwood’s deadline to choose as 12:01 a.m. on May 20.

If Atwood does not make a choice, then the default method to be used by the state is lethal injection.

Atwood’s attorneys have argued both methods would lead to a “torturous” amount of pain, and therefore neither are constitutional. They say Atwood is in a wheelchair and suffers from a spinal condition that would cause him "the maximum level of pain the human brain can process" if he were strapped to a gurney for lethal injection, pointing to the extended amount of time it takes the Arizona execution teams to insert IVs into death row prisoners.


Attorneys for Clarence Dixon, who was executed by lethal injection on May 11, said execution members took 40 minutes to insert IVs in Dixon's arms, before finally resorting to cutting into his groin and administering the drugs into his femoral vein.

Atwood's attorneys say the use of cyanide in a gas chamber is also unconstitutional, because it would lead to a gruesome death by asphyxiation. 

The state's last gas chamber execution using cyanide was Walter LaGrand in 1999, documented by witnesses as “agonizing” and lasting 18 minutes.

The last cyanide gas chamber death prior to LaGrand, the 1992 gas chamber execution of Don Harding, was described by his attorney as “slow, painful, degrading and inhumane.”

“To be clear, locking a human being in a chamber and flooding it with gas to extinguish his life should be a barbarism banished to history, not a current mode of correctional administration,” Atwood attorney Joseph Perkovich wrote in a letter to the Arizona Attorney General's Office and the Department of Corrections. “Nonetheless, numerous other gases instead of cyanide may be used to conduct a constitutional execution under Arizona law.”

Perkovich said Atwood proposed the use of nitrogen through an administrative grievance procedure sent on May 1, but the state refused to process it.  

He said Atwood had indeed made a choice of death by nitrogen gas, and the state was wrong to determine his failure to choose cyanide gas or lethal injection as a failure to choose at all. 

“Thus, this letter demands that the Department immediately implement a nitrogen lethal gas method,” Perkovich wrote on May 14. “Arizona’s constitution and statute fail to designate a kind of gas for its lethal gas method, and historically that determination has fallen to the Department.”

In a response letter to Perkovich written May 16, Chief Counsel of the Office of Attorney General Capital Litigation Section Jeff Sparks said current Department of Corrections procedures using cyanide did not violate any applicable statutory or constitutional provision, “and, therefore, ADCRR will not be making any changes to these procedures.”

Arizona is the only state that still has a functioning gas chamber. 

Atwood’s attorneys said a warden and deputy warden at the Eyman prison complex where he is being held “have approached Mr. Atwood ... and exhorted him to elect one of the existing methods of execution, notwithstanding the unavailability of a legally valid choice.”

“The choice between one form of torture and another form of torture is no choice at all,” Perkovich said Thursday. 

The Department of Corrections and the Attorney General’s Office did not immediately respond to questions about Atwood’s request as of Thursday evening.

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.

Two Executions In Six Hours: Florida Set For Historical Double Execution Tuesday

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.
