On December 3rd, 2020, an international three-person team of codebreakers made a breakthrough with the Zodiac Killer's unsolved 340-character cipher. The members of the team that cracked the code are: Sam Blake (Australia), Jarl Van Eycke (Belgium), and David Oranchak (USA).
By December 5th, the team finished cracking the cipher and sent the solution to the FBI.
Below is the full message from the Zodiac Killer that was hidden in the 340-character cipher for 51 years:
I HOPE YOU ARE HAVING LOTS OF FUN IN TRYING TO CATCH ME THAT WASNT ME ON THE TV SHOW WHICH BRINGS UP A POINT ABOUT ME I AM NOT AFRAID OF THE GAS CHAMBER BECAUSE IT WILL SEND ME TO PARADICE ALL THE SOONER BECAUSE I NOW HAVE ENOUGH SLAVES TO WORK FOR ME WHERE EVERYONE ELSE HAS NOTHING WHEN THEY REACH PARADICE SO THEY ARE AFRAID OF DEATH I AM NOT AFRAID BECAUSE I KNOW THAT MY NEW LIFE IS LIFE WILL BE AN EASY ONE IN PARADICE DEATH
