Det. Steven "Steve" Crosetti is a fictional character on the television drama series Homicide: Life on the Street portrayed by actor Jon Polito for the show's first two seasons. He is believed to be based on Baltimore Police Department Det. Terry McLarney, who was in the BPD homicide unit in David Simon's book Homicide: A Year on the Killing Streets; the character's ancestry was changed from Irish to Italian because Polito got the role. Crosetti is a veteran police detective who is partnered with Meldrick Lewis. A deeply religious man, Crosetti is shown to have both a scapular and a rosary. In one episode, he recounts an incident several years before when he had been gunned down, hit with at least three rounds. He spent considerable time in recovery, requiring multiple operations. As evidenced by the teleplay in "Gone for Goode" and later "Rockets' Dead Glare", Crosetti was fascinated and probably obsessed by the Lincoln assassination and rejected the belief that John Wilkes Booth was the lone assassin. In the first episode, he tells Meldrick he was up all night pondering the assassination. In "Rockets' Dead Glare", he is like a little kid when being shown Washington DC sites with any connection to Lincoln or Booth by the FBI Agent played by Ed Lauter. A dear friend of Crosetti's, a police officer named Chris Thormann, is shot in the head while apprehending a suspect. Thormann survives, but is left blind and deeply depressed. Crosetti tries his best to help him and his wife get through it, and forces himself into the investigation. Eventually, his emotions cloud his judgment and he apprehends the wrong suspect, but Lewis eventually arrests the right one. This storyline was based on the real-life shooting and blinding of BPD Officer Gene Cassidy, and is a major part of the David Simon book which spawned the series. Crosetti's own marriage had fallen apart sometime before the beginning of the series. He has a teenage daughter, Beatrice, whom Crosetti says "was as close to perfection as God allows." He apparently has at least joint custody. Crosetti is very protective of her, and is appalled that her mother was indifferent to the girl's having a boyfriend over to spend the night. Crosetti is said to have taken an extended vacation at the end of season 2. Lewis mentions that he goes to Atlantic City. In the sixth episode of
