الموسم 4، الحلقة 20: A young, well-to-do couple arrives late for a dinner party in an elegant apartment, only to find the other two couples brutally raped and murdered. Another victim is reported missing from the party, and Fin (Ice-T) and Duethorn (Erik Palladino) discover he is lying in the hospital near death from a head injury. Shortly after, a middle-aged couple in the park is found brutally raped and murdered. The detectives realize the killer has taken personal photos as well as money and jewelry as part of his/her crime spree. The only lead they have is a witness near the park who gives them enough information about the gold car near the scene, including a partial license number. The gold car is traced to the Bakers, who are supers of a high-end apartment building near the park and claim the car was stolen, but soon it turns up with two more bodies.
