The Washington State Penitentiary was locked down after the murder of Sergeant Cross. Superintendent Spalding had two primary goals for the lockdown. The first was to conduct a thorough search of the entire institution, confiscate contraband, and remove excess inmate property beyond a limited number of items that could fit in a foot locker under an inmate’s bed. The second was to make physical changes to the prison so that when the lockdown ended the world inside the walls would be a different place. Bulldozers were brought in. Lifers’ Park, People’s Park, and almost every grassy area inside the main compound were buried under a vast slab of concrete. In Spalding’s words, the architectural message he wanted to convey was, “this is a close custody institution, and we’re going to control it.”
