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 four 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 four 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 three individuals in the U.S. have been executed by hanging in 1993, 1994 and 1996.
