U.S. high court rejects Mississippi stay of execution WASHINGTON (Reuters) - The U.S. Supreme Court rejected a last-minute stay of execution on Wednesday for a Mississippi man who was convicted of two murders during convenience store robberies and who claimed to have a serious mental illness. The high court in two brief orders acted right before the time when Edwin Hart Turner was scheduled to be executed by lethal injection in Mississippi. Turner, 38, was convicted of murdering two men in 1995. On January 17, he requested a psychiatric exam as part of his claims that his attorney failed to properly research and present evidence of his longstanding mental illness.
