Charles Dean Hood initially won a reprieve just over an hour before he could have been put to death Tuesday when a state district judge withdrew his execution warrant. But an appeals court reinstated the warrant, saying the judge didn't have permission to spare Hood from lethal injection.

The warrant is scheduled to expire at midnight. The U.S. Supreme Court has denied three other appeals, likely clearing the way for Hood's execution.

Meanwhile, Oklahoma has executed its first death row inmate since last August.
