Justin Hartley's hit series Tracker ended a Halloween episode with a major death. During the Sunday, November 2, episode of the hit CBS show, Colter (Hartley) traveled to Massachusetts to assist on a case involving the murder of a nurse and the disappearance of an arsonist who vanished from a psychiatric facility. Colter figured out that the arsonist, who suffered from mental health issues, was kidnapped along with the lone survivor from his first fire. The search led Colter to a nun, who was preparing to ritually sacrifice the arsonist and his survivor.
