Cracked Code: Zodiac Killer's 340-Character Puzzle Finally Solved

It took 51 years, but the Zodiac Killer's 340-character cipher has finally been cracked.

As relayed by NotTheBee, three men solved the puzzle on Dec. 5, releasing a video explaining the process and their findings.

This is news because law enforcement officials were never able to discover the Zodiac Killer's identity.

The Zodiac Killer was a serial killer who claimed responsibility for 37 murders in northern California in the 1960s and '70s. Police were able to confirm only five. The puzzle solved below is from 1969.

The person claiming to be the Zodiac Killer sent letters to California media outlets with codes -- and clues -- supposedly related to his identity and murders.

According to the code-breakers, here is how the cipher reads:

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

The Zodiac Killer's reign of terror was documented in the book Zodiac, written by former San Francisco Chronicle political cartoonist Robert Graysmith and published in 1986. A movie of the same name starring Robert Downey Jr. and Jake Gyllenhaal followed in 2007.

But after these latest developments, it may be time for a sequel.
