MONTGOMERY, Ala. (AP) — Alabama has authorized the execution of a second inmate by nitrogen gas, months after the state became the first state to put a person to death with the previously untested method.

The Alabama Supreme Court on Thursday granted the state attorney general’s request for an execution date for Alan Eugene Miller, who survived a 2022 lethal injection attempt. The state’s governor will set the exact date of the execution for Miller, who was convicted of killing three men during a 1999 workplace shooting.

The Alabama attorney general’s office, in a February court filing seeking the execution date for Miller, said the execution would be carried out by nitrogen gas.

Alabama in January used nitrogen gas to execute Kenneth Smith. Smith shook and convulsed in seizure-like movements for several minutes on the death chamber gurney as he was put to death on Jan. 25.
