1x18 - Under Suspicion

Clarke fatally shoots the brother of a murder suspect, prompting a promise of retribution from the real suspect. And tempers flare at the station when Internal Affairs questions the detectives in the ensuing investigation. Meanwhile, Lt. Schwarz announces his engagement, which sets up the return of Farnsworth (and jealousy from Vitelli), and a shootout at the wedding where the murder suspect is shot by ""Doc"" and Phil is apparently fatally wounded.
