12. Collective

When a toy collector, Harry Pierce is shot dead by police in an suspected incident of domestic violence, Goren and Eames are led to a female con artist, Lori Purcell / Jocelyn Shapiro. She appears to have been exploiting lonely male collectors, but she is later found dead from carbon monoxide poisoning in a box to promote oxygen deprivation for erotic stimulation. The detectives' suspicions turn to a role-playing group obsessed with vampire fiction including her distraught boyfriend and first edition collector Dorian Cavanaugh. Goren and Eames collect the suspects together for a debriefing where they provoke Cavanaugh into confessing to Jocelyn's murder after he was led to believe she was exploiting him by the other members of the group.
