Episode #11 of the ZODIAC: A TO Z podcast titled “Perfect Crime: Inspirations” examines theories that the Zodiac imitated other elusive and notorious killers and was inspired by popular culture, fiction, film, and television, including the Batman comic books and series, TV shows such as Alfred Hitchcock Presents and Ironside, the films The Most Dangerous Game and Charlie Chan at Treasure Island, the strange case of a cab driver killing and taunting telephone calls to police, the still-unsolved murder of Cheri Jo Bates in Riverside, California, the story of the “3X Killer,” and more.

Episode #10 of the ZODIAC: A TO Z podcast titled “Melvin & Sam: The Strange Saga of a Zodiac Impostor” examines the popular myth that the real Zodiac was responsible for telephone calls to a TV talk show and to the home of celebrity lawyer Melvin Belli. A surviving victim and two police dispatchers who talked with the real Zodiac all agreed that the caller known as “Sam” was an impostor, but decades of confusion and popular myths in the books written by Robert Graysmith and the film adaptation by director David Fincher left some people convinced that the real Zodiac was responsible for the telephone calls to the TV show as well as later calls to Belli’s home. As usual, the facts tell a very different story.

Episode #7 of the new podcast ZODIAC: A TO Z features an examination of the still-unsolved murder of Cheri Jo Bates in Riverside, CA, and the possible connection to the Zodiac. Episode #6 includes an extended interview with Mike Morford (Host of the podcast Criminology and owner of ZodiacKillerSite.com) about the Bates case, the theories about her murder, the so-called “prime suspect,” and the Riverside writings linked to the Zodiac.
