YAKIMA, Wash. (AP) -- The Washington state Attorney General's office says an inmate who is scheduled to be executed this week is seeking a stay from the U.S. Supreme Court.
  
Cal Coburn Brown is scheduled to be executed Sept. 10 for the 1991 torture and murder of 22-year-old Holly Washa, a Burien woman.
  
Brown is challenging the state's new one-drug protocol for lethal injection, as well as the state Department of Corrections' authority to obtain that drug and the qualifications of the execution team.
  
A federal appeals court panel rejected his request for a stay on Saturday.
  
Brown also has motions pending before the Washington state Supreme Court and in King County Superior Court.
