Court Denies Claremore Man's Sanity Challenge

The Oklahoma Court of Criminal Appeals has denied a death row inmate's request to halt his execution over claims that he is insane and challenges to the state's drug formula.

But Benjamin Cole, 50, of Claremore had his upcoming execution was stayed anyway Friday, as the court delayed all pending executions at the request of Attorney General Scott Pruitt following concerns about the wrong drug that was shipped for an execution this week.

Cole's attorneys are pursuing a separate legal challenge, arguing his mental state has deteriorated while he's been on death row to the point that he is no longer sane enough to be executed.
