"I just don't think there's any other way anybody would have figured it out."
SIXTH VICTIM? The Case Breakers have asserted that the Zodiac is also responsible for a sixth killing in Riverside, California, on October 31, 1966.
Cheri Jo Bates was 18 years old when she was found dead in an alley on the Riverside City College campus.
In 1967, police received a handwritten letter which later led them to believe Bates' killing may have been committed by the Zodiac.
That theory was quashed in 2016 when investigators received an anonymous note from someone who claimed they'd written the earlier note as a "sick joke."
However, the Case Breakers have maintained that the Zodiac did kill Bates and claim investigators have blocked them from comparing her DNA to Poste's.
