Evidence against Sullivan[]

  • He was closely linked to the non-canonical Zodiac victim Cheri Jo Bates in 1966.
  • He was working at the campus and made people feel uneasy around him.
  • He did not show up for work after the Bates Murder and acted rather suspiciously. It is also said that he always wore the same outfit, After the murder he wore a completely new outfit.
  • He doesn’t just look similar to the sketch; he looks exactly like it.
  • The same vocabulary and writing style was used in the Confession Letter and the Zodiac Letters.
  • People at Riverside have stated that Ross wrote creepy poems.
  • He wrote an essay on how to disguise handwriting.
  • He moved to Santa Cruz in 1968.
  • He died in 1977 which might explain why the murders stopped.
  • In the decoding of the "340-chiffre" in Dec'2020 (see https://www.youtube.com/watch?v=-1oQLPRE21o), there is a strange erroneous code "NOSRVS" in the decoded text that could have been intentionally introduced by Sullivan as some sort of obfuscated "Ross Sullivan" acronym
