no accommodations suitable for a woman. The prison later converted the hospital quarters to accommodate four women, and later built a separate facility. The remaining Seatco inmates were transferred in 1888, and the facility was shut down, and the town changed its name to "Bucoda". When Washington became a state in 1889, the facility officially became the Washington State Penitentiary, but inmates nicknamed it "The Hill", "The Joint", "The Walls", and "The Pen". The first execution was carried out in 1906, and the final in 2010 of Cal Coburn Brown. Capital punishment in Washington became illegal in 2018. The most notable inmate at Walla Walla is Gary Ridgway, a serial killer known as the "Green River killer," who pleaded guilty in 2003 to the murders of 48 women to avoid the death penalty. He was still incarcerated there as of November 2021. Over a one-year period, starting in March 2002, more than one hundred inmates and staff at the Washington State Penitentiary were infected with Campylobacter jejuni. During this period, five clusters of the infection were identified, and genetic testing indicated that all of the bacteria were indistinguishable from each other. The source of this outbreak is not known, but contamination via pigeon feces, as well as unsafe food handling procedures, were examined. In June 2021, dozens of inmates were subjected to extreme heat when the air conditioning stopped working in the solitary confinement unit. Temperatures rose to over in the area surrounding the prison.
