Oklahoma has carried out the first of what prison officials say will be 11 executions this year. Scott Eizember was pronounced dead at 10:15 a.m. local time last Thursday, after authorities at the Oklahoma State Penitentiary strapped him to a gurney and injected him with a lethal cocktail of three drugs. Eizember is the eighth death row prisoner to be killed since Oklahoma resumed capital punishment in late 2021 after a six-year moratorium.

His killing came as one of Alabama’s largest suppliers of packaged gas said it will refuse to supply nitrogen to state gas chambers. A spokesperson for the company Airgas said in a statement, “Notwithstanding the philosophical and intellectual debate of the death penalty itself, supplying nitrogen for the purpose of human execution is not consistent with our company values.”
