Alan Eugene Miller, convicted of the 1999 killings of three men, was executed in Alabama using nitrogen hypoxia, becoming the second inmate to undergo this controversial method. The execution took place at a prison in Atmore, where Miller was pronounced dead at 6:38 p.m. State officials confirmed that Miller experienced shaking and trembling on the gurney for about two minutes, followed by gasping breaths for approximately six minutes.
Miller, who had requested death by nitrogen hypoxia, was fitted with a mask during the procedure, which lasted about 15 minutes. Despite some involuntary body movements, officials stated that the execution went according to plan and protocol.
