The Zodiac Killer: The Code That Took 51 Years To Crack

In 1969, a killer who called himself the Zodiac mailed a 340-symbol cipher to the San Francisco Chronicle. Nobody could read it for 51 years. This is the documented story of the Zodiac case: the attacks at Lake Herman Road, Blue Rock Springs, Lake Berryessa and Presidio Heights, the letters and ciphers, the investigation, and how three private citizens cracked the Z340 in December 2020. This video covers a real case. It is told from public records and major news reporting, without graphic detail and out of respect for the victims and their families. No victim photos are used; all visuals are illustrations, maps and cards. In memory of David Faraday, Betty Lou Jensen, Darlene Ferrin, Cecelia Shepard and Paul Stine. Survivors: Michael Mageau and Bryan Hartnell.
