Well Im not sure who you are attacking above, but the other poster, Robert something says you have not stated what the ciphers originate from would be my take on it in a nutshell? Maybe I do not know enough info to comment on it, I would stand guilty of that. I no longer remember the names of the major players in the case. Obviously there is no clear resolution on the case but I do believe they have some very strong suspects? I do not remember the names. Like in the Cooper case, there are some in the law enforcement area that have their own strong opinions on who the Zodiac was or is. To my memory, they do believe he is now deceased. No more murders have ever taken place in recent times, and if he were alive you can bet your last dollar he would want his ID all over it. So these famous cases, Zodiac, DB Cooper, Jon Bonet, Jack The Ripper, Black Dahlia, The Lindburgh kidnapping, and on and on, have a way of sucking us in. Add JFK and Alcatraz to the list. Pick your poison. All of these cases are old, and pretty much unsolved and open to tremendous debate.
