For over forty years of extensive head scratching, countless theories and the help of the most advanced computer systems known to man, all have so far failed to unlock the remaining cryptograms and clues sent to the authorities by the elusive killer, known only as the Zodiac.
Many interesting theories have been put forward, but as yet no conclusive proof has been ratified, that by popular consensus, has put an end to this frustrating murder mystery and finally unmask the killers identity once and for all..
The first three ciphers were sent to three different newspapers forming one message and known as the 408 cipher. It was solved by Donald Gene and Bettye June Harden of Salinas, California, who used homophonic substitution to identify the solution. Four months later on November 8th 1969 the 340 cipher arrived and to this day remains the most intriguing of them all, defying successive attempts to unlock its secret, if it has one at all. After all it may just be a collection of symbols without any reasonable order or logic, possibly constructed by a killer determined to seek payback for his original cipher being blown wide open in a matter of days.
But still the enthusiast is not discouraged, because for the individual or team that someday cracks open its code, may just release enough information that finally reveals the face of a killer, and along with it the most important thing of all, bringing some form of closure to all the victims family members and friends who have suffered intolerably throughout the last 45 years.
