The Zodiac Killer’s known murder series began in 1968 and ended in 1969, though some believe it started in 1966 ended in 1972. There was no preference for the sex or body type of victims. The first confirmed victims of the Zodiac Killer were 2 couples who were shot to death while parked at different areas, which were considered to be lovers’ lanes. In one instance, a male, Michael Magneau, survived the attack after being shot more than 4 times. Magneau described the Zodiac Killer as heavyset male, was around 5″8 in height and claimed that the shooter was driving brown car. It is thought that the murderer would use a bright light so that it would be difficult for victims to see his face. Most of the Zodiac Killer’s victims were shot to death, but in one instance a couple, who were picnicking, were stabbed. The female, Cecelia Shepard, died but the male, Bryan Hartnell, managed to survive. Although most of the victims were couples, the Zodiac was also known to have murdered a taxi cab driver.

On August 1, 1969, after 2 attacks had taken place, the Zodiac Killer began to write letters to the Vallejo Times Herald, the San Francisco Chronicle, and the San Francisco Examiner. These letters claimed that the person who was writing them took responsibility for the attacks and murders. In each of the letters was one-third of a cryptogram, in which the killer demanded be printed on the front page of each paper. On August 7, 1969 the killer wrote a second letter and referred to himself as the “Zodiac”. He gave many details about the murders which were unknown by the public.

In total, there are 5 known victims and 4 suspected victims of the Zodiac Killer, though he claimed to have murdered 37 people. Although detectives have a small list of potential suspects there have been no formal charges pressed against anyone. The case was marked inactive in 2004, but reopened in 2007. Much of the evidence, which has been brought forward against suspects since 2007, has been deemed inconclusive.
