A federal judge has ordered a three-month ban on all executions in Ohio following a botched killing earlier this year. The execution of Dennis McGuire in January lasted more than 30 minutes and saw him gasping for air. Ohio had planned on using higher doses of the same lethal injection drugs. But on Wednesday, District Judge Gregory Frost ruled Ohio’s new protocol is insufficient. The Ohio ruling is the latest in a series of developments challenging lethal injections in the United States. Three executions have been stayed nationwide in the weeks since Oklahoma botched the killing of Clayton Lockett, who died of a heart attack 43 minutes after the execution began.
