Dec. 20, 2009) 40 years ago today, the Zodiac killer mailed a letter to famed attorney Melvin Belli. For the bizarre events that preceded the mailing, including exclusive photos, click here.
Nov. 9, 2009) Today I received this e-mail from the FBI’s cryptography expert, Dan Olson, concerning the Zodiac’s unsolved 340 cipher:
————————————————–
“We havent seen any recent solutions or ideas that have generated a second look as of yet. If you can point us in the right direction we’ll be all over it. FYI, if we ever do see a good partial or full solution we will forward it with our endorsement to the cold case squad at SFPD, but we will give credit to where credit is due.
I dont have a graphic to share but here are more details you can post instead: Statistics for repeated characters for each line of text show a distinct higher randomness with the lines we’ve discussed (1-3 and 11-13). The higher randomness may be due in part or whole to greater care by the writer to not repeat characters on these lines. This indicates homophonic substitution. The opposite is true for lines 4, 10, 14, 17 and 18, these lines have many repeats. Additionally, there is far greater randomness for rows versus columns. This rules out any form of columnar or diagnal transpositions (a big step forward).
These same statistical tests were done on Z408. The results suggest that 340 is similar to 408 except for the bogus rows: overall randomness of 408 is .48, 340 is .50. Row randomness of 408 is .22, 340 is .19. Column randomness of 408 is .48, 340 is .68. By way of comparison, row and column randomness should be near identical if the 340 does not contain any message, or if there is a message that is evenly scrambled.
Thanks again for your help Tom.”

If you have a solution to the 340 cipher you’d like to share, I can pass it along to the FBI. Contact me. Discussion can be found here.
Sept. 22, 2009) Here’s the YouTube trailer for a TV project involving Zodiackiller.com:
Aug. 10, 2009) Before you check out the free, exclusive, two-hour Zodiac video below, keep in mind that even though I do my best, often I don’t have time to formally update Zodiackiller.com each time I receive interesting and valuable Zodiac information. Sometimes it can take me weeks or months to get the news to you, or it can just slip through the cracks and never get published. There is now a way for you to get all the good stuff delivered to your e-mail box immediately. Click here to find out how.
> Exactly five years ago, I filmed my own video of the various Zodiac crime scenes and other relevant locations. Click below for the free, exclusive, two-hour ULTIMATE Zodiac video on YouTube:
July 15, 2009) The recent Zodiackiller.com task-force meeting was a blast, and extremely informative to boot. Thanks to all who participated.
> I’ve written a feature article about the events of the last year or so in the Zodiac world. Click here for “The 13th Sign”.
May 14, 2009) About two weeks ago a woman came forward claiming to be the Zodiac killer’s daughter. She was the same woman who recently claimed to be the illegitimate daughter of President John F. Kennedy. Obviously her story is nonsense, as none of the witnesses to the Zodiac’s crimes ever described him as traveling in a motorcade.
In any event, discussion of these recent events — along with thousands of other Zodiac-related topics — can be found at the Zodiackiller.com message board.
> The next Zodiackiller.com task-force meeting is less than two months away. See the Jan. 5, 2009 update below for details.
Jan. 29, 2009) It was exactly 35 years ago that the Zodiac mailed one of his last letters. Today I updated the Zodiac Letters page to include two new additions. (Thanks to Howard Davis.)
Jan. 5, 2009) The Zodiackiller.com task-force meeting at the Roxie Theater in San Francisco might be history, but please enjoy the video at the bottom of this update of the subsequent Zodiac bus tour that 50 of us enjoyed.
> The next Zodiackiller.com task-force meeting will be held this July 5th (Sunday) 
at Blue Rock Springs Park in Vallejo, Calif. That date is the 40th anniversary of the Zodiac’s attack of Darlene Ferrin and Mike Mageau. Fittingly, the section of the park reserved for the event is called “The Pines” and was the site of the very first task-force meeting back in 2002, as pictured at left. “The Pines” features 22 picnic tables, two BBQs, plus nearby restrooms, water, and shade. (We will most probably tent a portion in case of heat/rain.) Best of all, it’s free. Beer and wine are permitted. Kids are welcome. After the recent hectic task-force meeting, we are looking forward to a mellow affair. Mingling! Discussion! Make your plans to be there. I can’t wait! (Starting a new diet tomorrow.) I’d like to thank the Dahlia for her help.
> I’ve put together a page of vintage Zodiac television programs that you can either view online, or save to your computer. Here’s a link. Enjoy!
