Cryptography Systems and Jack 1997

from Hit the Road Jack: Finding The Zodiac Hosted by Talk 4 Podcasting

Zodiac Killer boasted that his first and only cipher that was decrypted was rather simple in comparison to subsequent secret messages. We will look at the various systems taught by a Forensic Document Examiner. It is apparent that without a key, one would not be able to solve any further ciphers without it. So, this means Zodiac was communicating with someone that did. Nora’s diary holds some keys to Jack’s whereabouts and disposition as we move into 1997. Hit the Road Jack: Finding the Zodiac is broadcast live Fridays at 10AM PT on K4HD Radio - Hollywood Talk Radio (www.k4hd.com) part of Talk 4 Radio (www.talk4radio.com) on the Talk 4 Media Network (www.talk4media.com).
