A murderer who strangled four people to death, two of them children, and who has been on Alabama's death row for more than twenty years has received a stay of execution.

Daniel Lee Siebert, who suffers with terminal cancer, was due to be executed by lethal injection on Thursday but the execution was stayed because Siebert claimed his cancer medication would interact with lethal injection drugs and inflict unnecessary pain.

Erm - couldn't they just stop the cancer medication? I mean the guy's gonna die anyway.
