Reviewing evolving execution methods in the states

Law360 has this lengthy new piece, headlined “La.’s First Nitrogen Execution Reflects Broader Method Shift,” which discusses recent state execution method trends.  Here are a few excerpts:

Louisiana’s adoption of the nitrogen gas method is part of a broader shift to alternatives to lethal injections, which have faced intense judicial scrutiny as well as a shortage of raw materials needed to carry them out, resulting in hiatuses in executions in several states. Overall, states with capital punishment have signaled an intention to restart their execution programs, some of which have stalled for years, and for some states this involves shifting to new methods.

In January 2024, Alabama became the first jurisdiction in the world to use nitrogen gas, and has since used it to execute four people. Mississippi and Oklahoma also allow for the method but have yet to use it…. On March 7, South Carolina executed Brad Sigmon, a man convicted of murder, by firing squad — the first time the state used that method. His execution marked the first time in 15 years such a method was used to kill a prisoner….

Sigmon’s execution signaled an expansion of the use of firing squads, and other states might soon embrace it. Utah, Oklahoma, Mississippi, South Carolina and Idaho currently authorize the firing squad as an execution option.

Utah is the only state that has long allowed firing squads and has used it during the 20th century. Oklahoma and Mississippi added it as a backup method in the 2010s, while South Carolina legalized it in 2021 as a way to resume executions when drugs are unavailable. Idaho adopted it in 2023 for similar reasons.
