Missouri has executed a death row prisoner just 24 hours after the U.S. Supreme Court granted him a stay. Herbert Smulls was sentenced to death for the 1991 murder of a jewelry store owner. His attorneys had won a delay after arguing Missouri should be forced to name the compounding pharmacy used to produce the execution drug, which is not subject to federal oversight. But the Supreme Court followed up by denying all of Smulls’ appeals, clearing the way for his death. Missouri began using a new execution drug last year after a drug manufacturer stopped making the state’s long-running three-drug combination.
