Lethal injection, firing squad and nitrogen gas. A look at US execution methods

Louisiana is preparing this week to execute a man by nitrogen gas, the first execution in the state in 15 years

HOUSTON (AP) — Louisiana is set this week to execute a man by nitrogen gas, the first execution in the state in 15 years.

Jessie Hoffman Jr., 46, is scheduled to die on Tuesday in Louisiana. He was convicted of the 1996 murder of a woman in New Orleans. If Louisiana carries out the execution, it would join Alabama as the only two states to use nitrogen gas to put a prisoner to death.

Since the U.S. Supreme Court lifted its ban on capital punishment in 1976, states have used five different execution methods: lethal injection, electrocution, lethal gas, firing squad and hanging.

Here’s a look at how the U.S. executes people:

Most U.S. executions are by lethal injection


Lethal injection has been the preferred method in the modern era, with 1,428 carried out since 1976. Texas has done the most, killing 593 inmates, according to the Death Penalty Information Center, a Washington, D.C.-based nonprofit center.

Twenty-eight states as well as the U.S. military and U.S. government authorize the use of lethal injection, in which an inmate has a deadly mixture of drugs injected into their bodies as they are strapped to a gurney.

But throughout its use, lethal injection has been plagued by problems, including delays in finding suitable veins, needles becoming clogged or disengaged and problems with securing enough of the required drugs.

“A number of states are beginning to experiment with new methods of execution ... because of the problems with lethal injection,” said John Banzhaf, a professor emeritus of law at George Washington University Law School.

Use of electrocution is down since 2000


Nine states authorize the use of electrocution, including Alabama, Arkansas, Florida, Kentucky, Louisiana, Mississippi, Oklahoma, South Carolina and Tennessee. Since 1976, 163 electrocutions have been carried out. But only 19 have been done since 2000.

In this method, a person is strapped to a chair and has electrodes placed on their head and leg before a jolt of between 500 and 2,000 volts runs through their body. The last electrocution took place in 2020 in Tennessee.

Texas used electrocution from 1924 to 1964, killing 361 inmates, according to the state's Department of Criminal Justice. The electric chair used by Texas was nicknamed “Old Sparky.” It is now displayed at the Texas Prison Museum in Huntsville, where the state’s death chamber is located.

Louisiana could join Alabama in the use of nitrogen gas


Lethal gas is authorized as the default execution method in eight states: Alabama, Arizona, California, Louisiana, Mississippi, Missouri, Oklahoma and Wyoming.

From 1979 to 1999, 11 inmates were executed using this method, in which a prisoner would be strapped to a chair in an airtight chamber before it was filled with cyanide gas.

In 2024, Alabama revived the method when it became the first state to use nitrogen gas to execute Kenneth Eugene Smith. A mask is placed over a prisoner’s face and nitrogen gas is pumped in, depriving the person of oxygen and resulting in death.

Alabama has executed 4 inmates using nitrogen gas, with the last one taking place in February.

Louisiana would be the second state to use nitrogen gas as an execution method if it carries out the death sentence against Hoffman. After a federal appeals court on Friday vacated a preliminary injunction that had stopped the execution, Hoffman's lawyers said they planned to appeal to the Supreme Court.

Firing squads are rarely used in the modern era


Since 1977, only 4 inmates have been executed by firing squad, according to the Death Penalty Information Center.

On March 7, Brad Sigmon became the first person executed by firing squad in the U.S. in 15 years when he was put to death in South Carolina. The other three executions by firing squad took place in Utah.

Five states including Idaho, Mississippi, Oklahoma, South Carolina and Utah authorize its use, but it is not the primary execution method. For this method, an inmate is usually bound to a chair and is shot through the heart by a group of prison staffers standing 20 to 25 feet (6 to 7.6 meters) away.

Idaho has had firing squad executions on the books as a backup if lethal injection drugs are unavailable since 2023. But in the wake of last year’s botched lethal injection attempt on Thomas Eugene Creech, Gov. Brad Little recently signed a bill into law that makes the firing squad the state's primary execution method.

The bill’s sponsor, Republican Sen. Doug Ricks, has suggested Idaho could use a firing squad machine, triggering the guns electronically to eliminate the need for additional execution team members.

Hanging was once the primary execution method


In the U.S., hanging was the main method of execution until about the 1890s, according to the Death Penalty Information Center.

Data collected by researchers of U.S. executions from 1608 to 2002 found 9,322 people were put to death by hanging, in which a person was blindfolded and their hands and legs were secured before a noose was placed around the neck and they fell through a trap door.

But in capital punishment’s modern era, only 3 individuals in the U.S. have been executed by hanging in 1993, 1994 and 1996.

US Department of Justice announces decision to resume federal executions

The Department of Justice (DOJ) announced on Friday that it will resume the federal use of capital punishment and that it is seeking death sentences against 44 defendants. DOJ also said that it will use firing squads, electrocution, or nitrogen asphyxiation if the drug used in lethal injection is unavailable. The announcement follows the Restoring and Strengthening the Federal Death Penalty report, published on April 24. The report is especially critical of the moratorium on federal executions, ordered by Attorney General Merrick Garland in July 2021, to remain until the death penalty could be conducted “fairly and humanely.” Garland was concerned about the federal lethal injection protocol, which uses only one drug, pentobarbital, and the possibility that it causes “unnecessary pain and suffering.” In response to Garland’s moratorium and concerns, President Biden commuted the sentences of 37 prisoners on federal death row, leaving only three prisoners.

Arizona | Man who murdered pastor crucifixion style requests plea deal after parents killed in plane crash

Adam Sheafe, the California man who admitted to killing a New River, Arizona, pastor in a crucifixion-style attack, has asked prosecutors to offer him a plea deal that would result in a natural life sentence rather than the death penalty he had previously sought. Advisory council attorneys representing Sheafe sent a formal plea offer to prosecutors this week, about two weeks after his father and stepmother died in a plane crash at Marana Airport on April 8, according to 12 News. Sheafe, 51, is charged with first-degree murder in the death of William Schonemann, 76, pastor of New River Bible Church, who was found dead inside his home last April.

China | Man sentenced to death for murder executed in Yunnan

Tian Yongming, who was initially sentenced for a series of violent crimes and then had his sentence changed to death early this year, has been executed in Yunnan province following approval from China's top court. The execution was carried out by the Intermediate People's Court in Yuxi, Yunnan, on Tuesday, with local prosecutors supervising the process. Before the execution, Tian was allowed to meet with his family members. The case dates back to September 1996, when Tian was sentenced to nine years in prison for the rape and attempted murder of his sister-in-law. After his release on July 15, 2002, he plotted revenge against the woman. On the night of Nov 13, 2002, he broke into her home armed with a knife.

20 Minutes to Death: Witness to the Last Execution in France

The following document is a firsthand account of the final moments of Hamida Djandoubi, a convicted murderer executed by guillotine at Marseille’s Baumettes Prison on September 10, 1977. The record—dated September 9—was written by Monique Mabelly, a judge appointed by the state to witness the proceedings. Djandoubi’s execution would ultimately be the last carried out in France before capital punishment was abolished in 1981. At the time, President Valéry Giscard d'Estaing—who had publicly voiced his "deep aversion to the death penalty" prior to his election—rejected Djandoubi’s appeal for clemency. Choosing to let "justice take its course," the President allowed the execution to proceed, just as he had in two previous cases during his term:   Christian Ranucci , executed on July 28, 1976 and Jérôme Carrein , executed on June 23, 1977. Hamida Djandoubi , a Tunisian national, was sentenced to death for killing his former lover, Elisabeth Bousquet. He was execu...

Iran to execute first woman linked to mass protests after ‘forced confessions’

Bita Hemmati and three others have been sentenced to death for 'collusion' and 'propaganda.' Advocates claim the charges are baseless, citing a secretive process and state-televised interrogations. Iranian authorities are preparing to execute Bita Hemmati, the first woman sentenced to death in connection with the mass protests in Tehran in late December and January, according to the US-based non-profit the Human Rights Activists News Agency. Judge Iman Afshari, of Branch 26 of the Tehran Revolutionary Court, sentenced Hemmati, her husband, Mohammadreza Majidi Asl, and Behrouz Zamaninezhad, and Kourosh Zamaninezhad to death on the charge of “operational action for the hostile government of the United States and hostile groups,” in addition to discretionary imprisonment period of five years on the charge of “assembly and collusion against national security.”
