ST. LOUIS (AP) — A condemned Missouri inmate faces a potentially “gruesome and painful” execution because of a rare medical condition that compromises the man’s veins and causes multiple tumors in his head and throat, his attorney said Sunday. Russell Bucklew is scheduled to die by injection Tuesday evening for killing a former girlfriend’s new boyfriend in 1996 in eastern Missouri. Bucklew, 49, was moments away from execution in May 2014 when the U.S. Supreme Court halted it amid concerns about Bucklew’s medical condition.
