A DEATH row inmate is scheduled to be killed with nitrogen gas months after the new execution method caused another prisoner to suffer in agony for 22 minutes.
Convicted triple murderer Alan Eugene Miller , 59, will be put to death in Alabama on Thursday, marking the second-ever nitrogen gas execution by the state.
Miller, who was convicted of the workplace murders of Lee Holdbrooks, Christopher Scott Yancy, and Terry Jarvis in 2000, was due to die by lethal injection in 2022 – but his execution was called off after prison staff was unable to find a vein.
At the time, Miller was left hanging vertically on a gurney for over an hour as three workers tried and failed to locate a vein, poking him multiple times in the process.
Now, the convicted murderer is slated to be executed by nitrogen gas.
