U.S. Supreme Court denies Missouri murderer a chance to avoid execution by lethal injection

The U.S. Supreme Court on Monday denied a Missouri murderer a chance to avoid execution by lethal injection after his lawyers argued that the procedure might inflict undue agony because of a rare medical condition in an unusual case concerning which method should be used to impose the death penalty. The justices ruled 5-4 that Russell Bucklew, 50, had failed to present enough evidence for them to let him ask a lower court to allow him to be executed by lethal gas because lethal injection might rupture blood-filled tumours on his body that result from a congenital condition called cavernous hemangioma.

The ruling paves the way for Bucklew's execution by lethal injection. The court's five conservatives were in the majority and its four liberals dissented. Bucklew's lawyers had argued that the pain caused by lethal injection would violate the U.S. Constitution's prohibition on cruel and unusual punishment.
