Missing, Presumed Dead (S03E04)

After a shooting occurs, the neighbors remain tight-lipped and claim to have seen nothing. While pursuing a suspect, Sgt. Bob Cryer accidentally collides with a pedestrian. During his door-to-door inquiries, P.C. Yorkie Smith stumbles upon a man who keeps a variety of exotic animals, including snakes, owls, and a crocodile lounging in his bathtub. Meanwhile, D.S. Roach faces off against a group of thugs and, fueled by anger, attempts to retaliate with an iron bar until P.C. Carver intervenes. The next day, Roach's attackers receive a brutal message when they are kneecapped, signaling to D.I. Galloway who truly holds power in the area.
