Steven 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.

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.

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.

He finally accepts the truth when he hears the medical examiner's report, which states that Crosetti had high levels of alcohol, tranquilizers, and antidepressants in his system and died by drowning.

Lewis later recalls that before his vacation Crosetti had offered to give a him a childhood possession of his, a valuable vintage yo-yo, and realizes this was possibly a kind of going-away present.

Frank Pembleton, unwilling to attend the church funeral after his faith was shaken on a recent case, stands alone in his dress blues on the station house steps, saluting the fallen detective as the procession goes by.

Giardello finds himself in an afterlife version of the homicide squadroom, filled with past murder victims and police officers, and enters the break room to discover Crosetti and fellow detective Beau Felton drinking coffee and playing cards.

Giardello takes note of an empty chair and wonders if his son Mike might be the next to die, but Crosetti and Felton urge him not to worry about that or anything else from his life.
