John Hagen (played by actor Holt McCallany, during seasons 1-3)-a homicide detective who had emotional and psychological problems. He was apparently Raymond Caine's former partner who told Calleigh once that he couldn't stand being reminded of being the partner of dirty cop. He also had a brief relationship with Calleigh in Season 2, which he never seemed to have gotten over, and he has become jealous when he sees Calliegh with other men before and after their break-up. While pulling a crucial piece of evidence from a crime scene, he panicked when Calleigh came over to photograph the scene; he then crept up behind her and put his gun behind her head. Although he didn't mean to hurt her, it allowed him time to escape from the scene (she didn't know it was him at that time). He later shot himself in the Ballistics Lab in front of Calleigh during the season 3 finale.
