If you were to forget these words of warning, the thought of the Zodiac Killer might serve as a reminder. The Zodiac Killer was arguably the most devious murderer in the history of American serial killers.
Then, while people were trying to come to terms with of the shocking news, a mysterious call was received at Vallejo Police Department less than month later. On July 4, 1969, right after midnight, an unknown caller reported another horrible incident that took place in a public park some miles away. This time a young couple had been murdered. In a monotone voice, the caller claimed responsibility for the slayings. This is believed to be the first call made by the Zodiac Killer himself.
From this point on, the killer started communicating via letters and greetings cards. Each of these messages was concluded with the crossed-circle design pictured above. Later it became known as the Zodiac signature. These letters as well as some coded messages were sent by the killer to different, well-known newspapers, including the San Francisco Examiner and the Vallejo Times Herald.
Most of the letters contained threats and the killer’s long descriptions of his fantasies. He demanded that the people of the Bay Area wore “some nice Zodiac butons” [sic] – the crossed circle symbol – and that failure to do so would result in their death.

For years, the case of Zodiac Killer has been the subject of debate and controversy. Many people are still trying to solve the case and decode the ciphers. The information is there in the form of photographs, videos, letters, sketches, police reports as well as another top secret letter. But the investigators are no less in the dark.
As Wikipedia points out, the Zodiac Killer's crimes, as well as the letters and cryptograms sent to police and newspapers, have inspired many movies, novels and TV programs, not to mention other serial killers. Some of the famous movies are: Dirty Harry, The Zodiac Killer, Zodiac Killer, Zodiac, The Zodiac, and The Exorcist III.

There were many suspects in the case. Arthur Lee Allen, one of them, died in 1992. Among the other suspects was a man named Jack Tarrance, also now dead. However there is always the possibility that the Zodiac Killer is still out there and does not want his work to be credited to someone else. He clearly liked the attention.
Maybe he is dead by now; but maybe he is still out there, watching the world, while the world tries to solve his cryptograms and the mystery of his unforgettable crimes.
Though searching for the Zodiac Killer has become a part-time venture for professional detectives today, for amateurs, it is still a full-time obsession...
