3x3 - Cold Squad

Ali and Frank are assigned to find out who murdered plastic surgeon Marvin Michaelsen after a drug dealer identifies him as the man who removed his fingerprints, but the tension between the two soon ends up taking a higher priority than the investigation. Nicco and Mickey work together on the case of Dermot Wells, a garbage collector that is believed to have murdered his former co-worker, and make a bet on how soon they'll get a confession.
