Allegations & Notoriety

The Zodiac Killer was responsible for at least five murders in Northern California between 1968 and 1969, though the perpetrator claimed to have killed many more. The case became notorious partly because the killer sent taunting letters and cryptograms to local newspapers.

Evidence & Testimonies

According to reports from the San Francisco Chronicle, Poste's former daughter-in-law and another relative accused him of being the Zodiac Killer.
