A sketch of the Zodiac Killer
Fun Facts
In 2009, a woman claimed the Zodiac Killer was her father. However, her previous claims that she was JFK's daughter made her claims unlikely.
Corey Starliper; an amateur code breaker claims to have solved a 40 year old cipher.
Zodiac Killer Ciphers
Of the four ciphers sent to newspapers and police only one has been solved.
The Crimes
Of his seven victims, five were killed and 2 were injured.
Evidence Found
The Zodiac Killer was meticulous in his efforts to leave as little evidence as possible. Reports from the SFPD, Vallejo Police Dept., the, California DOJ, and the FBI prove otherwise.
The first letter was sent to Riverside Press-Enterprise on April 30, 1967
He taunted the police by sending newspapers letters that revealed his crimes.
He claimed he killed 37 people but police only have seven confirmed killings.
Victims
All his crimes were comitted within the San Francisco Bay Area

David Faraday and Betty Lou Jensen Killed Dec. 20, 1968 (Friday)
Darlene Ferrin and Mike Mageau (survived) July 5, 1969 (Saturday)
Cecelia Shepard and Bryan Hartnell (survived) Sept. 27- Sept. 29, 1969
Paul Stine Oct. 11, 1969 (Saturday)
Other possible victims include Robert Domingos and Linda Edwards, Cheri Jo Bates, Kathleen Johns, and Donna Lass
The last letter was mailed July 8,1974. It was called the Red Phantom Letter
At least two fingerprints were taken from the Vallejo Times-Herald and another was taken from thr cipher block sent to the San Francisco Examiner.
A palm print was found on the receeiver of a phone booth that was still wet and presumably left there by the Zodiac Killer. It was not given enough time to dry and was ruined in the lifting process.
Even though police investigated over 2,500 potential suspects, the case was never officially 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.
Other serial killers have imitated the Zodiac Killer including Heriberto Seda in NYC and Seito Sakakibara in Japan.
The Zodiac Killers victims.
The first cipher was solved by a History teacher and his wife.
Starliper believed that the “340” of the 340 cipher was significant, and had some tie-in with the U.S. Virgin Islands. It was then that he found out that 340 is the area code for a portion of the U.S Virgin Islands
"This is where it gets even creepier. 3+4+0=7. Right. So you get 7+0=7. 707...707 are the area codes for Vallejo, Napa, and Solano. So I figured, why not start this with Caesar code using 3,4.”
Has the Code of The Zodiac Killer Been Cracked?
The Message
After decoding the whole cipher this is what Starliper came up with.
