A three-judge panel of the 9th U.S. Circuit Court of Appeals has denied a Washington state death row inmate's request for an emergency stay of his execution.
Attorneys for Cal Coburn Brown could now ask the full court to review the case or appeal to the U.S. Supreme Court.
Brown is scheduled to be executed on Sept. 10 for the 1991 torture and murder of 22-year-old Holly Washa, a Burien woman.
Brown is challenging, among other things, the state's new one-drug system for lethal injection.
The three-judge panel rejected his request for a stay in a 2-1 decision on Saturday.
