r/ZodiacKiller

I’m a newb and will get out of your hair asap. Just want this little question answered so no need to jump on me.

I can’t find the z340 translation side by side. Like, exactly which symbols = which words. I know I could look at the thing and do it myself letter by letter, but I know it exists. Please help. Thanks.

I’ve always had this theory that the killer and the letter writer were not always the same. With PH being an exception.

Anyone with knowledge about cryptography who can tell me whether making those ciphers requires as much skill as decoding them?

In his 340 cipher Zodiac uses the word “paradice” three times. This isn’t a super common word and it’s odd he misspelled it and used it three times. Does his spelling of it mean something? Is paradice likely to be a clue to who he was?

Hello there. There are two unsolved Zodiac ciphers, so is anyone tried to solve them with AI? And what you think about those two ciphers, are they "real" ciphers, or killer just make up some random?

Not sure if this has been posted before, but according to Voigt, the Vallejo PD told him that attempt unsurprisingly led to disappointing results when the profile they were able to generate led to someone who couldn't had been Z. And that person's name won't be released for privacy reasons.

Quote:

"To the Vallejo Police Department, the desire to identify California’s still-at-large serial killer, the Zodiac, is as strong now as it was in the late 1960s, when the mysterious offender committed three area murders. Located about a 45-minute drive from San Francisco, modern-day Vallejo does not have an adequate police force, either in terms of budget or manpower. Still, it has been chasing the Zodiac for 57 years, and DNA is the last hope to catch him.

May 2018: In a story that made headlines across the globe, Vallejo police announced plans to genetically test items of evidence in an effort to obtain a DNA profile of the Zodiac killer. Then, in March 2019, Zodiackiller.com received an exclusive update on the testing process when it was announced that a genetic profile had been obtained from the submitted evidence. As a result, “The lab work has turned into more lab work,” the department said. “Vallejo PD is still at it. The hunt continues.”

And now, the latest — and exclusive — DNA update in the case of the Zodiac killer:

According to Vallejo police, the genetic profile that was previously obtained, belonged to an individual who could not have been the Zodiac killer. For privacy reasons, no other information was disclosed, adding to the mystery.

"While the killer remains at large — at least for the time being — the hunt continues" the Vallejo Police Department said", allegedly according to Voight again.

There's a probability this corroborates what Paul Holes said before about the postal worker contamination in the '60s. And Holes might be right when he said the two pieces of line from the lake were the best evidence.

And if the back of the stamps and flaps are no good, looking for testable areas again on the lines might be the last chance to at least conclusively put a name and face to a dead offender as being the assailant who committed the lake attack. And if that bear minimum can be achieved, they can maybe come to the satisfactory conclusion that it was the same shooter who incriminated himself into those 3 scenes — similar to what happened with Colonial Parkway in 2024 — when LE said it's a deceased offender there, too. And then gave a new update 2 years afterward in Jan of this year that there's enough evidence now to come to the conclusion that it was the same guy at all of them.

And probably the expectation, at this point, with this one, is to get that press conference out there at some point in the foreseeable future where they say, "If that person were living today, they'd be charged and indicted".

It’s obvious that the Zodiac name and logo is most likely completely taken from the watch brand. Have anybody ever considered someone working for the watch brand itself to be zodiac?

First theory: The person would have known that using both the brand’s name and logo would attract a lot of attention to the brand and could potentially increase sales. Therefore, they may have intentionally used the name and logo as a kind of advertisement.

Second theory: When the killer needed a name and logo for himself, he probably wouldn’t simply look down at his wrist and completely copy the design of his watch. I have another explanation: perhaps the killer had worked, or was working, for the brand, meaning it played a much bigger role in his life than simply being the brand of his watch.
As we all know, the Zodiac was a very unusual killer who seemed to enjoy teasing the police. Maybe he simply used the logo and name from his workplace, thinking that nobody would think much of it.

I know this this highly unlikely and it has probably already been investigated, so please don’t come after me in the comments, I was just sharing a thought.
