He does mention forrest in it so maybe he was a Forest Ranger and that is his identity. Or he has given his name Forest Whitaker or Gump I don’t know.

The Cipher is very clever if he’s done what I suspect he has.

When the code is decrypter and the message becomes viaible what is the first thing everyone is going to be aware of? His name not being in the deciphered message. Everyone gets disappointed and lose hope of any breakthrough via the Text because the Cipher part of this mystery has been deciphered and no name is there. What if there is a encrypted message hidden not only under the Cipher itself that was cracked, but the real encrypted stuff of importance is actually in the deciphered text itself somewhere. A chipher within a Cipher.

I mean the whole Idea of a cipher is to encrypt and encode a message of vast importance to you and this information in the hands of then enemy would be deadly and disasterous. Yet what is it he appears to have taken a lot of time and effort to try and keep it concealed for its importance? "I like killing people – Slaves collection mission – Afterlife…Narnia like place called ‘Paradice’.

Now what would you go to all that trouble and bother to encipher that load of crap for? I would say….. He hasn’t, not for that message anyway!

I think the letter and it’s author are telling the truth when it claims "In this Cipher is my Identity". I think the Cipher is one deliberately meant to obfuscate. The Cipher when decoded reveals a completely useless rant about slaves in an afterlife.
This is just my opinion but I think there is probably something pointing to his identity that is encoded with the decoded cipher itself, weather its a rail fence type Cipher message or Running Key type of encryption I have no idea as I am completely useless when It comes to the Cipher’s and decoding them.

He said his IDENTITY is in the cipher,NOT his name. Maybe theres a clue in there?

That’s exactly what I thought. The wording is important.

Yes. The way I’ve thought about it is that he only states that the cipher contains his identity. Identity can mean several things and Zodiac seems to simply go with the concept of explaining what makes him The Zodiac.

He does not at any point say that the cipher contains his actual legal given name. The way he has worded this whole thing is very ambiguous, on purpose I bet. He tricks people into thinking the cipher will reveal his social security number or something, and gets a good laugh out of thinking about everyone trying to solve it.

I’ve personally come to the conclusion that the final garbled part of the cipher is just filler, or perhaps some anagram (the most sensible one I came up with so far was ‘here be epithet I omit’). Like he states, he will not give out his real name – one of the few things I believe Zodiac actually was truthful about.

(I also find the Chronicle letter especially interesting due to the ink that is running out. One can see where he has maybe stopped to think when writing, and the pen has rejuvenated a bit. I wonder if LE ever considered the possibility mentioned by Tahoe about Zodiac possibly having dabbed the pen on his tongue?)
