Zodiac

On July 4, 1969, an unknown man attacks Darlene Ferrin and Mike Mageau with a handgun at a lovers' lane in Vallejo, California. Only Mike survives. One month later, the San Francisco Chronicle receives encrypted letters written by the killer calling himself the "Zodiac," who threatens to kill a dozen people unless his coded message containing his identity is published. Political cartoonist Robert Graysmith, who correctly guesses that his identity is not in the message, is not taken seriously by crime reporter Paul Avery or the editors and is excluded from the initial details about the killings. When the newspaper publishes the letters, a married couple deciphers one. In September, the killer stabs law student Bryan Hartnell and Cecelia Shepard at Lake Berryessa in Napa County; Cecelia dies two days later.
