WALLA WALLA -- A Washington State Penitentiary inmate has been charged with stabbing a fellow prisoner last fall.
Jose Sanchez Guillen, 26, is accused in Walla Walla County Superior Court of first-degree assault. The charge was filed Tuesday.
Officials said Guillen used a homemade shank to stab and slice inmate Victor Carrillo Diaz in a brutal attack. The assault, which occurred in the dining facility of a prison housing unit Sept. 25, 2009, reportedly was recorded by the unit's surveillance cameras and witnessed by several correctional officers.
Authorities later found two homemade shanks inside a garbage can under a flight of stairs. Officials also allegedly located several items of evidence in Guillen's cell, including plastic razor handles, metal razor blades and broken toothbrushes.
His cell mate, Jose Jesus Morado Sanchez, 27, was charged Tuesday with complicity to first-degree assault.
Diaz was treated at Providence St. Mary Medical Center for his injuries after the attack.
