Alabama man shook violently on gurney during first-ever nitrogen gas execution
ATMORE, Ala. (AP) — A man put to death using nitrogen gas appeared to shake and convulse on the gurney as Alabama carried out the first-of-its-kind execution that once again placed the United States at the forefront of the debate over capital punishment.
Kenneth Eugene Smith, 58, was pronounced dead at 8:25 p.m. Thursday at an Alabama prison after breathing the gas through a face mask to cause oxygen deprivation. It marked the first time that a new execution method has been used in the United States since lethal injection, now the most commonly used method, was introduced in 1982.
The execution took about 22 minutes between the opening and closing of the curtains to the viewing room.
Smith appeared to remain conscious for several minutes after the gas started flowing. For at least two minutes, he shook violently and writhed on the gurney, sometimes pulling against the restraints and shaking the gurney with the force of his movements. That was followed by several minutes of heavy breathing, until breathing was no longer perceptible.
