"On Oct. 6, a group of over 40 former law enforcement investigators, journalists and military personnel known as the Case Breakers claimed to have discovered the identity of the infamous Zodiac Killer.
The Zodiac terrorized Northern California in the 1960s and sent cryptic, encoded messages to the police describing the murders...The group has now identified the serial murderer as Gary Francis Poste, who had passed away in 2018.
They were able to link the original Zodiac killings to another unsolved murder that happened in 1966, the death of Cheri Jo Bates, whose body was found in an alley way in Riverside, California.
In the letters sent to the police between 1969 and 1974, the Zodiac claimed to have murdered 37 people, however only five of those incidents have been directly linked to the same killer.
If the Case Breakers are correct, Bates would have been the Zodiacs sixth confirmed murder."
