Zodiac Killer’s Code Deciphered – Proves It Was Arthur Leigh Allen?
Corey Starliper, a hobby code-cracker, thinks that he has deciphered the Zodiac Killer‘s code, finally ending the 41 year old mystery. If his deciphering is correct (which if you think about it, if he followed a code, and came out to what it says…how can it not be true???) then the letter sent to police gives (Arthur) Leigh Allen as the killer!
Now, a whole lot of people have claimed to have deciphered the code over the years. This one looks pretty legit. Here’s what Corey Starliper had to say about how he cracked the code from Foster City Patch.
“I thought, there’s no way … that Zodiac is going to be prosaic enough not to mention the U.S. Virgin Islands in this code. This is where it gets even creepier. 3+4+0=7. Right. So you get 7+0=7. 707…707 are the area codes for Vallejo, Napa, and Solano. So I figured, why not start this with Caesar code using 3,4.”
Caesar code is a substitution type cipher where an encoder has “simply replaced each letter in a message with the letter that is three places further down the alphabet,” according tohttp://www.simonsingh.net/The_Black_Chamber/caesar.html.
This doesn’t mean the 340 is such an easy task to decode, considering the fact that the original 340 cipher is full of symbols: >, +, and ▲ being just a few of the signs found in the code. To combat this problem, Starliper extracted symbols and changed them to letters they could correspond with. For example, a ^ or < symbol could be interpreted as inverted or sideways “V”s.
“I first went in there and I did that,” he said. After everything symbolic had been interpreted alphabetically, he started applying reverse Caesar shifts. He found the first two letters to be “K” and “I”.
“What are the next two going to be? right? I figure, what’s the first word he’s going to throw in there? Kill,” said Starliper. “And I was able to keep going from there.” For the first few lines, the pattern remained constant, but it changed beyond that. He said he was able to figure out the non-patterned series that by finding “similarities in the numerical sequence.”
Starliper split his work into two sessions of 6 hours and 3 hours. When he was done, he had decoded the following text:”
