MCALESTER —The execution of convicted murderer Richard Glossip has been stayed by Gov. Mary Fallin, who said in a news release the state received a drug for his execution it is not authorized to use.

Glossip's 3 p.m. Wednesday execution already had been postponed momentarily as the Oklahoma Department of Corrections waited for the U.S. Supreme Court to make a decision on Glossip's final appeal. At 4 p.m., state Corrections Department officials announced the execution would be stayed for 37 days. It would mark the third time Glossip has come within hours of execution before receiving a stay.

“That's just crazy," Glossip, 52, said on speaker phone as a supporter held the phone up for the media outside the prison walls.

Glossip was incredulous on the phone, just moments after the stay was issued. He said he was still trying to piece together exactly what happened and why he was still alive.
