what happens to mcnulty at the end of the wire
Jimmy McNulty The case is "solved" when McNulty encounters a mentally ill homeless man who has started using the modus operandi of the phony serial killer. McNulty brings the man, his final criminal, to justice. McNulty and Freamon then leave the police department. After attending a detective's wake (of sorts) in their honor, McNulty leaves the bar sober and returns home, where he and Russell have reconciled. The next day, McNulty returns to Richmond, finds the homeless man he had put there, and drives him back to Baltimore. On the way back, he stops his car, gets out and looks at the city, leading to the series-ending montage.
