Welcome to the Zodiac Ciphers blog. Here I will try to post all the latest news on efforts to solve the mysterious Zodiac ciphers, which, with only one exception, have remained unsolved for over 40 years.
The Zodiac Killer was a serial killer who claimed several victims in Northern California in the 1960s and 1970s. He terrorized the area with his crimes, letters, and taunts, and has never been caught. Some of his letters included mysterious cryptograms. Only one has been solved definitively. Do the rest of them contain any real messages? If so, would they shed any light at all on the identity of the mysterious killer?

The old Zodiac Ciphers wiki, which was previous found at wiki.zodiac-ciphers.dreamhosters.com, was being overrun by loathsome spammers, so I had to take the site down and convert it over to the new location, where I have been able to lock it down:
Let me know if anything appears to be missing!
Also, contact me if you are interested in contributing content to the Wiki, a place to collect fact-based observations, experiments, and analysis of the Zodiac ciphers.
