The parolee suspected in the slaying of Colorado's prisons chief wrote in 2006 that fantasizing about torturing and killing prison staff kept him sane during his incarceration.
Evan Spencer Ebel wrote about his fantasies in a letter to someone outside prison. The letter was confiscated by guards in November 2006 and was obtained Tuesday by The Associated Press. A prosecutor referred to it in 2008 when Ebel was sentenced to four years in prison for punching a guard in the face.
Because of a paperwork error, Ebel was allowed to serve the four years at the same time as a sentence he was already serving.
Ebel got out of prison early on Jan. 28, and authorities suspect him in the death of Tom Clements and pizza deliveryman Nathan Leon last month.
