John Rose from Australia has uncovered some interesting features within the Zodiac Killer's unsolved 340 Cipher, mailed to the San Francisco Chronicle on November 8th 1969. This does not tackle the entirety of the cipher, as the extremities of the code still remain unbroken. What it does do however is show an extremely promising correlation between the 340 Cipher and Halloween Card, using predominantly 81 characters in a 9 X 9 grid formation at the center of the cipher. It has been achieved using nothing more than Dave Oranchak's Web Toy, implementing zkdecrypto cipher-cracking software. The tool can be found on the Zodiac Killer Ciphers website here.

Just a quick overview of how I got to my cipher solution is using just the simple symbol being replaced by a letter technique (like the 408 was solved), no strange math, no weird jumping all over the place, no anagrams (which is what almost all 340 solutions are, which can lead to any answer), just the simple technique used to solve the first cipher, but with the small twist. Also I had kept in mind a few years back the FBI has said they believe half the cipher could be mumbo jumbo to throw people off, but half does look to be correct. I noticed the "+" symbol followed by the semi filled circle followed by another "+" vertically directly in the middle which instantly made me think of the "ArA" in "Paradice" on the halloween card, so I put that in which then made "ire" appear attached to the bottom of "paradice" - of course "fire" and I went from there (with a few other things that came to mind), the twist being the "Paradice Slaves" cross (the same as the halloween card) and I believe the 9x9 quadrant, which the word "rope" (automatically making the second word "rope" in the corner reverse "L" shape formed a kind of border in my head). The main part which I am quite sure of is the "Paradice Slaves", "By rope, by fire, by knife, by gun" parts replicating the halloween card. That is the solid core of my solution, and I believe the halloween card was literally giving them the answer to the cipher.

Great Work! This is one of the most encouraging solutions I have seen. Zodiac wrote "Your Secret PAL" in the Halloween Card......Pal (inverted) is next to Rader name

In Addition the the inverted PAL, I noticed DERBY centered in the middle of Paradice. Derby, KS is the largest suburb of Witchita, KS where Dennis Rader grew up. A good way to include the area he is from in his name raDERBY. The "BY" in DerBY is the only "BY" that does not have an associated Murder method in the GRID.

You said the code symbol "Z" stood out to you where the D is in raDer. D for Dennis?

Interesting theory! Unfortunately you will face the very same problem that others face with the Dennis Rader theory. Rader was stationed overseas during the Zodiac era, and Robert Leuci was in New York. The challenge would be to place either of them in California on any of the dates when the Zodiac is known to have been active. You will also have the problem of convincing people that Leuci was a serial killer, let alone a killer. There is presently no evidence to suggest this. At least with Rader, everybody accepts that he was a serial killer. The other huge problem is the passage of time. Records tend to get buried or lost. I tried to get law enforcement in Solano County interested in checking records at the nearby air base to see if Rader may have made regular trips back to the US as a part of his work detail, and also to see if these dates could match with known Zodiac activity, but I received a rather blunt reply that nobody is presently investigating the case. I have reached the conclusion that nobody in law enforcement wants anything to do with the Zodiac these days. As far as the authorities are concerned, he was either Allen Leigh or he got away. But good luck in your investigations.

I was wondering how anyone could be sure that Z did not use anagrams? Couldn’t he have constructed the puzzle however he wanted?

Michele, many people have considered anagrams. In fact they seem to be the "topic of the year" on most of the Zodiac cipher forums. The huge problem with anagrams of course is that they simply add more variability to what is already a highly variable problem. Even if a "solution" is found that shows the entire cipher is one big anagram, who is going to believe it? Other people will come up with other solutions based on other anagrams. Therein lies the problem when relying on anagrams as a solution. 10/29/2019 02:36:57 am
John, this is very cool!! I haven't bee doing a whole lot of Zodiac research for the last few years so this is the first time I have seen this and it is a cool find. The way that it looks just like the words from the Halloween card makes it even more interesting. I would bet that everything outside of the 9x9 grid there is even more to be found.

I agree with JR. People often get too caught up in perceived timelines. It seems highly likely to me that the Zodiac was providing clues or perhaps even a key to the puzzle in that Halloween card. In fact he even said so on the front of the card, didn't he?!

It would be nice to hear from Dave Oranchak John. I think you have made an extremely good effort in fitting the words you have using limited character space. The good thing about it, is that you are not relying on anagrams and artistic license to twist the results. It is created using only the Web Toy software. My guess is that Dave Oranchak will tell you that the flexibility of so many characters in the grid of 81 could produce several results similar to yours. The difficult part is arranging it correctly from scratch. Nevertheless I am impressed by your achievement. Have you tried creating a different set up in the grid or around it? Dave may be able to demonstrate alternatives, which will go a long way to showing the percentages, likelihood and validity of your finding. All the best Rich.

Cheers Shawn, I gathered that is what Dave would say, having looked at it myself. Nevertheless a very interesting result, based on the webtoy, with no manipulation. Probably the best effort I have seen to date. The Rader word search puzzle being exactly 340 characters is very interesting. My guess this is deliberate on Rader's part. Obviously he is not Zodiac, as he was serving in Japan at the time. So the discovery of Rader in the 340 'solution' is likely incidental.

Richard, since I’ve contributed numerous times to your website, and since I mentioned you favorably during my House of Mystery monologue, I hope you won’t mind if I use the Comments section to address Dave Oranchak, at least rhetorically, since he doesn’t reply to my emails or posts on his infamous You Tube video. As Gavin de Becker might say, Dave has been given The Gift of Fear. This article was linked over on ZodiacKillerSite under the thread title “340 partial solve via webtoy?”

Uh, let’s try this again. I’ve divided my comment into two parts. It’s exasperating that one can’t edit or even just delete comments on this website.

4. “contrived scenarios”—Dave Oranchak has lazily compared me to Thomas Horan, who often presents intricately detailed hypotheses to explain his belief that there was no Zodiac, only a letter writer who created a counterfeit killer connecting unrelated crimes. As I’ve pointed out on numerous occasions, Horan’s fundamental thesis is nonsensical. He says, in his most recent incarnation of the hoax theory, that Robert Graysmith was involved in sending the Zodiac letters, in order to give himself a serial killer to write about.

This partial solution is interesting and may well be the solution, or at least part of the solution. Unfortunately it could also be a complete coincidence, considering that only a very small portion of the entire cipher has been involved. A false solution can result from such highly selective reasoning. I do not mean to rain on anyone's hard work, but I have personally found that it is possible to make this cipher point to other culprits. I recently came up with a very convincing partial solution that is similar to this one, but which points to Herb Baumeister as the Zodiac, as crazy as this sounds! I used his name and the names of members of his family and filled in a large part of the cipher in a seemingly logical way, which coincidentally matches with the design of an old Hebrew amulet that forms a swastika. I am sure it would be possible to make this cipher fit many other names and patterns.

I have now had some time to reflect on this cipher solution by John Rose and am having second thoughts about my earlier criticisms above. I had to ask myself what are the possibilities that this solution is a complete coincidence, and in all honesty I had to admit that the chances of it being a coincidence are extremely slim. The paradice/Slaves cross is quite complex and I think far too complex to mean it could be reproduced so well in the cipher. It seems to me that the Zodiac must have intended it this way. So my apologies to Doranchak, but I disagree with him that this is just "random and coincidental background noise", or whatever it was he dismissed it as. Put it this way, if ever you picked up a wallet on the street and found a scrap of paper inside with a name on it, would you just dismiss the scrap of paper as just something random that could have come from anywhere, or would you logically presume that the name may have some connection to the owner of the wallet? Then if you dug deeper into the wallet and found the same name, written exactly the same way, wouldn't it be logical to presume that the two names and the wallet are connected? I think it would.

I am finding myself in agreement with Dave Oranchak's recent estimation that the 340 cipher has much more in common with fake ciphers than real ciphers. But I would take this one step further. I think the cipher may be a "twist" on this idea, which, in fact, makes it a legitimate cipher after all, just not a true homophonic cipher... at least not in its entirety.

I admit to being the person who thought up the triangles leading to a diamond theory. That is to say, I practiced what the Zodiac preached and "connected the dots".

I note that Oranchak has resorted to calling the 340 a fake cipher, following another failed "homophonic solution" attempt, rather than examine other possibilities. Whenever people show him other possibilities he automatically discounts and discredits them on the basis of "too much improbability". But as any professional cryptographer should know, it is sometimes the seemingly improbable that turns out to be the actual solution. The thing about cryptography is that the person who designed a cipher may actually be trying to trick the cryptographer into making presumptions that are not in fact true. Simply because an idea does not fit an idea of a homophonic cipher or appear to conform to certain "rules" of probability, this does not mean it should be ruled out. It may be that the cipher works by different rules because it is a different kind of cipher! Oranchak often shows a reluctance to look at other possibilities, which suggests a highly selective and subjective manner of thinking. But this is just my estimation, based on what I have noticed by reading online discussions.

This is good but shortening the cipher to 81 characters does allow for more solutions to be made to fit.
