Oklahoma has agreed to stay the execution of prisoner Charles Warner for six months following the botched execution of another prisoner. Warner was due to be executed last week on the same night as Clayton Lockett, who died of a heart attack 43 minutes after the execution began. On Thursday, the Oklahoma attorney general’s office agreed to a request from Warner’s lawyers to stay his execution pending a state probe into the one that went awry. Warner is now due to be executed on November 13.
