Ridgway was placed in solitary confinement at Washington State Penitentiary in Walla Walla in January 2004.  Roughly around 2005, Ridgway made more pleas with the Federal government and was transferred to Airway Heights where he was put in a minimum-medium security tank. On May 14, 2015, he was transferred to the USP Florence , a high-security federal prison east of Cañon City, Colorado . In September 2015, after a public outcry and discussions with Governor Jay Inslee , Corrections Secretary Bernie Warner announced that Ridgway would be transferred back to Washington to be "easily accessible" for open murder investigations.  Ridgway was returned by chartered plane to Washington from the High Security Federal Prison in Florence, Colorado, on October 24, 2015.
