On December 5th, 2020 Sam Blake, Jarl Van Eycke, David Oranchak finally cracked the Zodiac Killer’s unsolved 340-character cipher.
The Zodiac Killer was a serial killer who was active in Northern California in the 1960s and ’70s. His name came from the taunting letters he would send to the San Francisco Bay Area press which included a total of four ciphers. It was confirmed that he killed at least five people, though he claimed to have murdered 37.
Police still don’t know the identity of the Zodiac Killer, though they’ve long hoped that solving his ciphers would reveal more details about him.
