SPOKANE, Wash. (AP) -- The state Supreme Court has rejected a petition from Spokane serial killer Robert Yates.
The court on Thursday dismissed Yates' petition, ruling that none of his claims of error merited review or a hearing.
Yates' petition raised 25 grounds for relief, including ineffective assistance of counsel, juror bias and numerous procedural issues.
Yates in 2000 was convicted of 13 counts of first degree murder and one count of attempted murder in Spokane County, and in a plea deal was sentenced to 408 years in prison instead of death. But the next year he was sentenced to death for two murders in Pierce County.
He is on death row at the Washington State Penitentiary in Walla Walla.
