Chris Keller - Season 5

Season 5

Keller is transferred back to Oz the following year, after Agent Taylor proves he lied about his involvement in Hank Schillinger's murder. He is then put in protective custody while the District Attorney's office tries to convict him of an unsolved murder (which he had indeed committed). While in protective custody, he begins an affair with one of the guards, Officer Claire Howell, but soon tires of her and begins rejecting her advances. Enraged, Howell brutally beats him, putting him in the infirmary, and tells her superiors that he attacked her. After he recuperates from his injuries, he is found guilty of the murder charge, and sentenced to death.
