US state of Alabama plans to carry out the first known judicial execution of a prisoner using asphyxiation with nitrogen gas on Thursday evening, a closely watched new method the state hopes to advance as a viable, simpler alternative to lethal injections. Kenneth Smith, convicted of a 1988 murder-for-hire, is a rare prisoner who has already survived one execution attempt. In November 2022, Alabama officials aborted his execution by lethal injection after struggling for hours to insert an intravenous line’s needle in his body.
