In this episode, we pick up the investigation of the Lake Berryessa attack that we covered in episode 2. There are some very good clues found at the crime scene. A murder of a cab driver in San Francisco appears to be random, most likely committed during a robbery. But very quickly the Zodiac resumes his communication with the press. He has a need to take credit for his work and to poke fun at the police. Police will see just how close they were to catching this killer. We're joined in the episode by Dr. Katherine Ramsland who weighs in with her thoughts on Zodiac. Expect to hear more from Dr. Ramsland and other experts in their field as this season of Criminology unfolds. The hunt for the Zodiac is just beginning.
