Alabama death row inmate Kenneth Eugene Smith has been executed by nitrogen gas – making him the first person in US history to be put to death through the controversial method.
Smith, 58, was pronounced dead at 8.25pm CT on Thursday at the William C Holman Correctional Facility in Atmore, Alabama, almost three decades after he was convicted in the 1988 murder-for-hire plot of Elizabeth Sennett.
His religious adviser Reverend Jeff Hood, who witnessed the execution, told reporters what he saw was a man “struggling for their life” for a staggering 22 minutes.
Alabama authorities insist the execution went to plan, despite predicting the untested method would lead to unconsciousness within seconds and death in minutes.
But, witnesses said Smith appeared conscious for several minutes, shaking and writhing on the gurney.
“We didn’t see somebody go unconscious in 30 seconds,” said Rev Hood. “What we saw was minutes of someone struggling for their life.”
Smith’s death came after the US Supreme Court denied a final, 11th-hour bid to stay of execution. The ruling received dissent from Justice Sonia Sotomayor who wrote that the state had selected Smith as a “guinea pig” by using the untested method.
