S3·E12 The City That Bleeds (1)

Bolander, Munch, Howard and Felton all meet to serve a warrant, but Bolander, Howard and Felton are shot in an ambush. Pembleton becomes the primary in the investigation and is partnered with a detective who specializes in the psychology of their prime suspect: a pedophile. Stan's ex-partner Mitch Drummond offers his help. Kay's father and Beau's wife and the kids come to the hospital. A clerical error is discovered to be the cause of why the detectives went to the door marked 201, instead of 210.
