“Dear Editor This is the Zodiac Speaking …”
The evening of Friday, December 20, 1968, was the first date of Betty Lou Jensen and David Faraday of Benicia, California. The couple planned to attend a Christmas concert at a nearby high school two or three blocks from Jensen’s home. Instead, they visited a friend and stopped at a local restaurant, then drove out Lake Herman Road. At about 10:15 p.m. Faraday parked his mother’s Rambler in a gravel turnout, which was a well-known lovers’ lane.
Shortly after 11 p.m., another car pulled into the turnout and parked beside them. The driver apparently got out with a pistol and ordered them out of the Rambler. Jensen exited first. When Faraday was halfway out, the man shot Faraday in the head. Fleeing, Jensen was gunned down twenty-eight feet from the car with five shots through her back. The man then drove off. Their bodies were found minutes later by Stella Borges, who lived nearby. The sheriff’s department investigated but found no leads.
On July 4, 1969, sometime around midnight, Darlene Ferrin and Michael Mageau were shot multiple times while parked at a golf course in Vallejo, four miles from where Jensen and Faraday were murdered. At 12:40 am, a man phoned the police department from a phone booth only a few blocks away from the police station and claimed responsibility for the attack as well as for the murders of Jensen and Farady.
On August 1, 1969, nearly identical letters were received by the Vallejo Times-Herald, the San Francisco Chronicle, and the San Francisco Examiner in which the author took credit for the shootings. Each letter also included one-third of a 408-symbol cryptogram which the killer claimed contained his identity. The killer demanded they be printed on each paper’s front page or he would “cruse [sic] around all weekend killing lone people in the night then move on to kill again, until I end up with a dozen people over the weekend.” The threatened murders did not happen, and all three parts were eventually published.
On August 7, 1969, another letter was received at the San Francisco Examiner with the salutation “Dear Editor This is the Zodiac speaking”. It was the first time the killer had referred to himself with this name. In it, the Zodiac included details about the murders which had not been released to the public as well as a message to the police that when they cracked his code “they will have me”. On August 8, 1969, Donald and Bettye Harden of Salinas, California, cracked the 408-symbol cryptogram. No name appears in the decoded text.
From September 27 to October 11, 1969, the Zodiac murdered three more people. On November 8, 1969, the Zodiac mailed a card with another cryptogram consisting of 340 characters. The 340-character cipher has never been decoded.
