Arkansas carried out its first execution since 2005 on Thursday night, putting to death convicted murderer Ledell Lee four minutes before his death warrant was set to expire at midnight. Lee was one of eight condemned inmates the state had planned to execute over 11 days in an unprecedented rush before the state’s supply of midazolam, one of three drugs it uses for lethal injections, expires at the end of the month. A flurry of court challenges has disrupted the schedule. Courts blocked three executions earlier in the week, and another inmate who was scheduled to be executed next week has received a stay. The state has scheduled two other executions for Monday, and another for Thursday.
