Following a new lead, Burns investigates students at Columbia University who studied with one of the previous victims, a college professor. Burns thinks that he has found the serial killer: Stuart Richards (Richard Cox), a gay music graduate student with schizophrenic disorder who attacks him with a knife in Morningside Park. Burns brings the man into custody, but shortly afterward, Ted's mutilated body is found. The police dismiss the murder as a lover's quarrel turned violent and put out an arrest warrant for Gregory, with whom Burns earlier had a fight over his relationship with Ted.
