An inmate in Alabama is set to become the second person known to be executed by nitrogen hypoxia, a controversial method critics say is tantamount to torture. Alan Eugene Miller, 59, was previously scheduled for lethal injection two years ago, but the attempt was called off due to vein access issues.
Republican Alabama Gov. Kay Ivey has designated a 30-hour window for Miller's execution, following a federal lawsuit settlement over the use of nitrogen gas in his execution. The settlement, whose terms remain confidential, was hailed by the state Attorney General as proof of the method's constitutionality.
