Analysis of the case's forty year old evidence yields a fingerprint not previously detected. This enables the team to finally I.D. the killer, who turns out to have committed suicide prior to the most recent murder. Sam talks to a writer who researched the original case and learns of a young boy who claimed to have witnessed one of the crimes. That boy, whose story was not believed at the time, is later revealed to be the copycat killer. Jack recuperates from his gun shot would at the home of his extremely wealthy, extremely deranged mother, Miriam. Meanwhile, Sharon (aka Jill) decides to redecorate Jack's lair by eliminating all traces of Sam. When a now healthy Jack returns to the lair, he is enraged by the changes Sharon has made. Sam's in-laws come to town to see Chloe perform in a school play and are angered when Sam is unable to attend at the last minute.
