Alabama Executes Alan Eugene Miller Using Controversial Nitrogen Gas Method

Miller's execution marks the second time the U.S. has used nitrogen hypoxia, amid ongoing debates about its humaneness.

Alan Eugene Miller, 59, was executed for the 1999 murders of three coworkers in Pelham, Alabama.
Miller's execution is the second in the U.S. to use nitrogen gas, following Kenneth Smith's earlier this year.
Witnesses reported Miller shaking and gasping for air, similar to the first nitrogen gas execution in January.
Miller had previously survived a failed lethal injection attempt in 2022 due to difficulties establishing an IV line.
The use of nitrogen hypoxia has sparked debate, with some arguing it is humane and others calling it torturous.
