A condemned cop killer who received a stay of execution from the U.S. Supreme Court because of his challenge of lethal injections appealed to the Court for a second stay of execution on Monday.

A three-judge panel of the 11th U.S. Circuit Court of Appeals turned down Clarence Hill’s appeal Friday night, leaving him with only limited court options to escape Wednesday’s scheduled execution for the 1982 murder of a police officer in a savings and loan robbery.
