On December 3, 2020, A group of three people made a major discovery deciphering the unresolved 340-character encrypted message of the serial killer Zodiac, who was never arrested. The text of the message was unknown for 51 years, since 1969. On December 5, the team was able to decode the message, and sent the solution to the FBI. The three men who broke the code were Australian mathematician Sam Blake, and developers Jarl Van Eycke from Belgium and David Oranchak from the USA.
