At the conclusion of the episode, Munch returns to the precinct to gather his belongings, where he and Cragen shake hands as Cragen remarks, "you had one hell of a run, Sergeant Munch." Munch has returned, post-retirement, to help his colleagues in the fifteenth-season finale "Spring Awakening" and the seventeenth-season episode "Fashionable Crimes".
The character of Munch has appeared in a total of nine series on five networks since the character's debut in 1993.
After Homicide: Life on the Street concluded its seventh season in May 1999, the character transferred into the Law & Order universe as a regular character on Law & Order: Special Victims Unit (both Homicide and the original Law & Order had crossed-over numerous times before, and Munch had featured centrally in each crossover).
Though his age is never directly stated on Homicide, a few clues are presented pointing to it.In the season 15 episode, "Internal Affairs," SVU Captain Donald Cragen informs Detective Olivia Benson that Munch has submitted his retirement papers, stating that a recent case (portrayed in the episode "American Tragedy") had hit him hard.
