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.

Tibetan protesters executed for Lhasa riot killings

Tibetan exiles have reported the first executions of those convicted for rioting last year in Lhasa, with at least two people put to death in a rare implementation of capital punishment in the restive region. Two Tibetans convicted of arson and sentenced to death in April were executed on Tuesday morning in Lhasa, reported The Tibetan Centre for Human Rights and Democracy, which is based in the Indian town of Dharamsala—the home in exile of the Dalai Lama. It said that Lobsang Gyaltsen and Loyak had been sentenced to death for their part in setting fire to five shops in the Tibetan capital, killing seven people, in the riot that rocked Lhasa in March last year. Officials say that 21 people — including three Tibetan protesters — died in the violence, which embarrassed Beijing just as it was preparing to stage the Olympic Games and prompted a security crackdown across the Himalayan region. The body of Mr. Gyaltsen had been returned to his family and then submitted to a river burial—an un...

Two Germans to be caned, jailed for Singapore train graffiti

"Singapore: Disneyland with the death penalty" A Singapore court sentenced two Germans to nine months in prison and three strokes of the cane on Thursday after they pleaded guilty to breaking into a depot and spray-painting graffiti on a commuter train carriage. Andreas Von Knorre, 22, and Elton Hinz, 21, both expressed remorse while being sentenced in the state courts of the island republic. “This is the darkest episode of my entire life,” said Von Knorre. “I want to apologise to the state of Singapore for the stupid act ... I’ve learnt my lesson and will never do it again.” Hinz added: “I promise I will never do it again. I want to apologise to you, and my family for the shame and situation I’ve put them into.”  Both were dressed in prison uniform — a white T-shirt and brown trousers with the word “Prisoner” down the sides and on the back. They spoke to the court in English. Singapore sentences hundreds of prisoners to caning each year as part of a syst...

Indiana | ‘Dignity’ is a poor excuse for blocking press access to state executions

Indiana law says that the press has no right to be present when the state carries out executions. It limits those who can attend to the warden of the prison where the execution is carried out, immediate family members of the crime victim, no more than five friends or relatives of the convicted person, the prison physician, and the prison chaplain. Only if an inmate selects a member of the press as one of the five friends may they attend.

Iran: Delara Darabi has now been scheduled for execution

Delara Darabi has now been scheduled for execution, according to the Iranian newspaper Etemad on 18 April, according to another source on 20 April. She was convicted of murdering a relative when she was 17. Unless the Judiciary intervenes, she can now escape execution only if the woman’s entire family accept payment of diyeh, or blood money. One of the familly is said to be undecided. Iran is a state party to the International Covenant on Civil and Political Rights and the Convention on the Rights of the Child, which prohibit the use of the death penalty against people convicted of crimes committed when they were under 18.

Florida | Former prison warden who oversaw executions urges corrections workers to not participate in them

Recently Florida carried out the execution of Dusty Spencer , a 74-year-old Marine veteran, for the murder of his wife, Karen, in 1992. It was the ninth Florida execution this year. For their own sake, I urge Florida’s corrections workers to refuse to carry out another one. Before you dismiss me as some soft lefty, you should know that I am an Air Force veteran. I voted for Ron DeSantis for governor twice—and for Donald Trump for president three times.

Iraq: Saddam Hussein Execution was Moved Forward Because of Gaddafi Rescue Plans, Judge Says

Saddam Hussein's execution on December 30, 2006 The execution of former Iraqi President Saddam Hussein was accelerated due to the belief that the then Libyan leader, Muammar El-Gaddafi, had a plan to rescue him from prison, Judge Mounir Haddad revealed today. Hadad, who presided over the trial of Hussein, revealed to the Al-Arabiya Satellite Channel Point of Order program new details of the trial against the former president and his last moments before being hanged, including the 'health and welfare' votes for the magistrate himself . According to his testimony, the application of the death penalty to Saddam Hussein was precipitated because authorities knew that El-Gaddafi - later murdered in 2011 - was allegedly trying to bribe US guards who guarded him to rescue him from prison. He added that, contrary to previous reports from the local and US press, former Iraqi President Jalal Talabani gave his 'implicit approval' for Hussein's execution, an...

Iran: Prisoner of conscience Mohsen Amir Aslani hanged for ‘different interpretation of Quran’

Mohsen Amir Aslani NCRI - The Iranian Resistance calls on the UN High Commissioner for Human Rights and the Human Rights Council, as well as all international human rights organizations to strongly condemn the execution of prisoner of conscience Mr Mohsen Amir Aslani on charges of “corruption on earth; changing Islam’s principles and secondary laws; and new interpretation of Quran”.  It further calls for adoption of binding decisions against the growing number of arbitrary executions by the religious fascism ruling Iran. Mr. Amir Aslani, 37, who had been in prison since eight years ago, was once sentenced to four years in prison which was later commuted to twenty-eight months. However, as more fabricated charges were brought against him, the head henchman Judge Salavati condemned him to death. The Iranian regime has refraining from handing over the body of this prisoner to his family through stonewalling and offering contradictory answers to them. The execution...
