A federal appeals court has denied Arizona's request to lift a judge's order blocking the scheduled execution of death row inmate Jeffrey Landrigan.
The 9th U.S. Circuit Court of Appeals ruled in San Francisco early Tuesday that the state had failed to provide enough information to show why the court should lift the stay imposed by a federal district judge on Monday.
Arizona had scheduled the execution for Tuesday at 10 a.m. MST.
But Landrigan's lawyers contend he would suffocate painfully if a knockout drug doesn't render him unconscious before other drugs are administered to paralyze his muscles and stop his heart.
In issuing the stay Monday, U.S. District Judge Roslyn Silver said more time was needed to consider that argument.
