A 74-year-old Oklahoma death row inmate will be executed this evening unless the U-S Supreme Court steps in.
John Boltz is to be put to death at 6 p-m for killing his 22-year-old stepson in 1984 and would be the oldest person ever executed in Oklahoma.
But Boltz's attorneys are asking the Supreme Court to block the execution while he challenges the constitutionality of the lethal injection used to execute inmates in Oklahoma.
Boltz was convicted of stabbing Doug Kirby to death when Kirby went to Boltz's home to talk about threats Boltz had made to Pat Kirby. Pat Kirby was Doug Kirby's mother and was married to Boltz at the time.
Medical examiners say Doug Kirby was stabbed eight times and nearly decapitated.
