  4. 4. Facts• The notorious and very bizarre serial killer who called himself The Zodiac remains one of the worlds great unsolved cases.• In Oct., 1966, a girl was viciously murdered in Riverside, California when she permitted a man to help start her car up• that he had intentionally disabled when she was in her school library. This homicide began a ghoulish series of murders that panicked the people of the San Francisco area.• For years the Zodiac taunted the police with weird ciphers, phone calls, insulting and cryptic messages• Even though police investigated over 2,500 potential suspects, the case was never solved.• There were a few suspects that stood out, but the forensic technology of the times was not advanced enough to nail any one of them conclusively.
  5. 5. Letters• The zodiac sent the police and newspapers letters about his killings and of what how he did them.• The Zodiac sent at least 18 letters, usually to newspapers but occasionally to private citizens.• The first letter was sent July 31, 1969 and the last on July 8, 1974.• In 1966, 1967 and 1978, communications were received that might have been from the Zodiac.• However its not known for sure if he was the author.
  6. 6. Cryptographs• The zodiac killer also used cryptographs to send coded messages to the police.• The cryptographs were full of symbols and shapes that made up a message
  7. 7. Possible Suspects• Many different suspects were interviewed about the case and if they were involved• Suspects:•• Arthur Leigh Allen• Bruce Davis• Lawrence Kane• Michael OHare• Richard Marshall• Ted Kaczynski

  15. 15. Details on the two murders• According to the police report, the victims were apparently approached while occupying Faradays station wagon. Shots were fired into the vehicle in an apparent effort to force them out. Jensen exited the front passenger door first, followed by Faraday. Faraday was shot as he emerged from the car, Jensen was then shot as she fled on foot. It was the first date Jensen had ever been allowed on and the crime shocked the community. The shooting could not be explained by Faradays family. Jensens family was equally dumbfounded.

Ferrins first husband, James Phillips Crabtree, was also briefly a suspect. According to surviving victim Mageau, he and Ferrin had parked at the isolated location to talk.

  33. 33. • The End The Zodiac killer is still at large today even though there has been no incidents currently• I think that the zodiac is either dead or old and not capable of doing anything else• I think that the best suspect would have to be Arthur Leigh Allen because of these things that he claims he would do if he was a killer:• He would like to kill couples at random.• He would taunt the police with letters detailing his crimes.• He would sign the letters with the cross-circle symbol from his watch.• He would call himself "Zodiac."• He would wear make-up to change his appearance.• He would attach a flashlight to the barrel of his gun in order to shoot at night.• He would fool women into stopping their cars in rural areas by claiming they had problems with their tires, then loosen their lug nuts and eventually take them captive.
