OLYMPIA — The state Supreme Court has lifted the stay of execution for Cal Coburn Brown. The high court unanimously ruled today that Brown’s claims that the state’s execution process is unconstitutional was moot because of a recent change made by the state Department of Corrections. Earlier this year, the state changed its method of execution from a three-drug cocktail to a one-drug system. Last year, the high court issued the stay just hours before Brown was set to die for torturing and killing a Burien woman in 1991. The state can now reschedule the execution, but the earliest it could happen is September.
