Zodiac Killer Ciphers

The Zodiac Killer was a serial killer active in California in the late 1960s and early 1970s. He was never formally identified or charged, though a number of people have since written books and articles claiming to have named him.

There are four main Zodiac Killer Ciphers / cryptograms that are widely believed to have been sent by him:
* Z408 – 31 Jul 1969 – (solved)
* Z340 – 08 Nov 1969 – cipher (unsolved)
* Z13 – 20 Apr 1970 – “my name is” cipher (unsolved)
* Z32 – 26 Jun 1970 – the “map code” cipher (unsolved)

There are also several other ciphers which have been attributed to him (but which seem rather more likely to be hoaxes and/or copycats), most notably:-

* Z148
* Z63

    My name is…… zodiac aka a monument

  2. Richard( Rick) is hinting at Zodiac as being a musician. I met Harry Martin in 2010 and he said he had been misled previously and the real Zodiac was a musician and reporter in Napa. he gave me a name. He said the guys wife had told him one day before she “took a fall”, whatever that means.Harry is dead now, but he was the ears and eyes in Napa for decades. He would know.

  3. Rob: the way that the Zodiac Killer quoted bits from The Mikado certainly makes him seem a little more musical than average, so he could very possibly have been a musician.

    What happened to the wife?

  4. Nickspelling, I completely agree. Everything points to his being a musician, and maybe one who explored the Great American Songbook. He also has/had a penchant for history. He also was a reader, and clearly a writer. Could he have been a journalist and musicians who worked for SF Chron? Maybe as a crime beat reporter? Or one of the other papers associated with the case? I always questioned Pat Stanley’s version of driving by the phone booth on Main Street to see a phone left off the receiver. Who were his associates at the radio station at the time? Could one one them been riding with Pat and “discovered” the phone off the hook, and urged Pat to take credit? The wife took a fall. Thats all i know. I am researching any and all Sf Chron writers and will soon look into any vallejo Napa writers who could be musicians and historians. Whoever the Zodiac is or was had interests that included Norse mythology, crime beats/ fellow journalists, music etc. If he is a crime or court meat reporter, it would make so much sense. I personally think any and all misspelled words were a ruse.

  5. Reading through your work. You have great insights Nick

  6. I will not discuss my work, but suffice it to say I am an investigator.The FBI know far more than they let on. Let me make some very quick declarations,
    hat makes anyone believe that Zodiac was not intentionally leaving false clues? He was known to lie. The first slip up sleuths fall into is believing the Zodiac tells the truth. He wanted to prove he was the killer, but everything else was false, meant to slip up investigators.
    After a number of years of studying the killer, I can determine the following may be true. Note the word may.

    1. The killer probably used a typewriter for his profession. He was driven to write, but sent only hand written messages because nobody would expect him to hand write anything. I believe he may have been a reporter. I believe he may have covered crime or court proceedings.
    The killer may have been exposed to just how we operate when conducting an investigation.If he was a reporter for the Chron or Vallejo Times or Napa Register, he would have had access to police and also access to how other killers make mistakes. If I wrote for a paper, I would have no fear of being monitored, because nobody would expect me to hand write anything. The killer interests include the legal system and journalism. The killer may have been a journalist covering the story, outsmarting everyone because he was both killer and investigator.

    2. The killer wore his hair cut short during an era where long hair dominated youth. This leads me to believe he was employable and conservative. He mentions no “Hippy’ words or rock and roll music. Therefore , his musical likes are Jazz or Classical or both,

    3. The killer mentioned intimate parts of the Mikado, and also an old Norse word. This shows familiarity with history and music. He had education.

    4. The killer wanted to change the world. That was his broad goal.

    5. I expect someone of Norse or German heritage , based on the facial features. A tall man with a slouch. Dead eyes. Smart , but quiet.Purposely misspelled words in order to fool people, and perhaps even finger false suspects.

    6. The killer would have been attracted to the Red Mask comics when he was around age 9-10, and if 1952 is the date of the death by rope, knife, water comic, that would place his birthday at 1942-1943

    7. The killer has probably killed by water and fire and we simply do not know it. If by fire, he would have hidden it well, and probably have been a “watcher” Arsonists have been arrested by us because they return to the scene of the crime.

    8. Tom voight is correct in assuming that the killers handwriting, in combination with DNA matches will solve this case. I highly suggest starting to vet the reporters who were close to the investigation. The Zodiac was, almost certainly, in their midst.

    It is interesting that many, even in positions of authority are open to, or accepting the fact, that Dr George Hodel was the Black Dahlia killer. One of the most notorious crimes of the 1940’s with a graphic crime scene of Jack the Ripper proportions.

    Now one of the main people behind the pursuit of Dr Hodels guilt was infact his son, Steve, a former NYPD detective.

    What has this to do with the Zodiac killer you may ask? Well, Steve Hodel also claims his father as guilty of those crimes also.

  8. RobLaw on July 14, 2015 at 8:56 pm said:

    I don’t know how much you have looked into previously, but it would be good Nick if you could maybe look into Steve Hodels blog and examine the evidence. I would love to hear a considered view and article from you. It is certainly striking when you see the composite drawing/impression of the Zodiac Killer and images of an older Dr Hodel.

  9. RobLaw on July 14, 2015 at 9:16 pm said:

    One last point for now Nick, my first post tonight was written and awaiting moderation before I saw Robs’ post above me, written literally seconds before.

    It was fascinating to read Robs points, and how easy it would be to match Dr Hodel up to them, he was a musical prodigy as a child, scored 186 on an early I.Q test and ticks many,many boxes for the Zodiac. . Even part 5, the attraction to the Red Mask comics. Rob puts the Zodiacs birth year at 1942-3. Of course this would not match Dr Hodels birth, yet it would his son Steve, who was born November 1941.

    Idk just bringing up this up since I seen a post that said the Zodiac killer might be a musician, Maybe he was an army officer’s kid and he was an early mind control test at the Presidio(Major Michael Aquino ,Satanist, temple of set founder) that got jealous he couldn’t go on to hit it big like the (other?) Laurel Canyon kids of the army and navy that went on to be big musicians The doors, Crosby, stills nash and others on the “hippie and drug and music scene” In my mind I think his last message on the Radians being +/- along the radians is him trying to throw everyone off because his first message of the map is correct and he was told by his handlers to stop and quit messing with program, he got payed off or they killed him. Lots of Satanism and lucies and such involved. Manson murders happened that area to. idk just speculation.

    I have been working on deciphering the Z340 CIPHER. Here is what I have came up with. The code deciphers to, ” SVEHGTNEIADENEWTSIE “. The message is, ” SEVEN IN HUNTINGTON DIE AND I WASTED THEM “.

    RobLaw,
    I’ve done extensive work on the Zodiac Killer Ciphers. Here is something that I thought you might want to look at. The Post Card Cipher reads on the left side the following; First line reads in cipher; ” Circle Outline with Centered Cross, R, O, Square with right side diagonally filled in, + “, or ” DGNLE “, ” GLENDALE “. The second line reads, ” Backwards D, I, V, Circle with line horizontally through it, Y, Square Filled In, Backwards L, Backwards P “, or ” OTBHULAE “, ” BOTH ULAE “. ULAE(Universal Limited Art Editions) was a fine art publishing company established in 1957 in San Francisco. Was it the company who made the postcard(s)? The third line of cipher is, “I, Z, Y, +, F, B, I, >, Backwards C, + “, or ” TEUESLTEVE “, or ” LIEUT(LIEUTENANT) STEVE “. Could this be the Steve Hodel who was a LAPD Homicide Detective at that time and stated that his dad was the Zodiac Killer? The fourth line of cipher reads, ” O, , Filled in Circle, F, B, Triangle with period in center of it “, or ” NNUTETS, LA “, ” SUNSET, LA “. Sunset LA was known as Old Sunset at that time and is near Hazelton.

  13. Rick A. Roberts on December 11, 2015 at 10:47 pm said:

    RobLaw,
    The right side of the post card reads as follows; first line of cipher is, ” Y, Square Outline, Circle with left side vertically filled in, M “, or ” UYIH “, ” HI YU ” or ” HI YOU “. Second line of cipher is, ” M, Backwards D, Circle with cross centered in it, Triangle outline, M, Backwards p “, or ” HODIHE “, ” HI DE HO “. Third line of cipher is, ” I, Q “, or ” TM “. This could mean ” EMPTY “,or ” MT ” for ” Mount ” or ” Mountain “. Fourth line cipher is, ” Circle outline with centered cross, R, O, Square with right diagonal side filled in, + “, or ” DGNLE “, ” GLENDALE “. Last line of cipher reads, ” Backwards D, I, V, Circle with line horizontally through center of it, Y, Square filled in, Backwards L, Backwards P “, or ” BOTH ULAE “.

    The ” MY NAME IS __ ” Cipher. The cipher reads, ” A, E, N, Circle Outline with Cross Centered in it, Circle Outline with ” 8 ” Centered in it “, K, Circle Outline with ” 8 ” Centered in it, M, Circle outline with ” 8 ” centered in it, Perpendicular sign, N, T, H “. This deciphers to, ” TENDOHLOHHOHINTH “, or ” HOLDEN TOOTH IN TOOTH “. Also, the eighth letter of the alphabet is ” H “. The three eights in the Circle Outlines = ” HHH “. Dr. Hodel’s initials were HHH . His son Steve claimed that his Dad, Dr, Hodel was the Black dahlia Killer and the Zodiac Killer.

    The “Harden Decipherment” was probably the biggest setback in the Zodiac investigation. I really feel that anyone who looks at the method used by Harden, and then looks at the decipherment, would also find it laughable. Harden based the decipherment on a belief that the word “Kill” would appear repeatedly throughout the message. He then scanned for double symbols, attributed “LL” to them, and randomly associated letters to symbols to fit a preconceived message that he had in his head.
    – Take the first two lines for instance. Harden claims that it contains 4 I’s, all of which are represented by four seperate symbols. He also claims that there are 5 E’s, all of which are represented by different symbols. That’s completely ridiculous. You can make the argument that it is a Homophonic Cipher if you want, but what method was used by Harden to determine his was the correct decipherment? It’s not the correct decipherment.
    – The fact that there are more symbols than letters in the English language is fairly easily explained, and not by assuming it is a Homophonic Cipher. The symbols are mostly astrological symbols that don’t represent letters. Zodiac repeatedly tried to tell people how to decipher it, but nobody listened (because of Harden). With the “Map” message he wrote in plain lettering “The Mt. Diablo code concerns Radians, and # inches along the radians”. This actually applied to more than the diablo code. Look at the 408 cipher that was supposedly deciphered:
    – The first symbol is a triangle = (trine, 120° radian 2.0944). The next symbol = (Novile, 40° radian 0.698132). The symbol // (Parallel). The thirteenth symbol, looks like a k rotated 90° clockwise = (Quincunx 150° radian 2.61799). The symbol that is a K rotated 90° Counterclockwise =(Semi-Sextile 30° radian 0.523599). The symbol Q = (Quintile 72° radian 1.25664). The symbol “^” = (Vigintile 18° radian 0.314159). The symbol bQ =(Bi-Quintile 144° radian 2.51327). The upside down “T” = (Decile 36° radian 0.628319). The symbol of square with dot in middle = (sesqui-square 135° radian 2.35619). There are many more, the list goes on.
    – We may possibly find out that the Zodiac Killings were the work of more than one person, a collaboration. Possibly of the “Community for Life” Four Pi Movement at the Waller House in SF at the time. Membership included Charles Manson, Manson family members, Dk, some Gypsy Jokers, led by Father P. The Four P movement was actively involved in satanism, sacrifice, and murder. They have a subchapter called the “Black Cross” whose whole purpose is murder. Affiliated with Ordo Templi Orientis O.T.O. (The Zodiac symbol cirle with cross is combination of OTO and a black cross). All O.T.O. member positions are called degrees (I-XII).
    – Lastly, if you are good at Steganography, take a look at the Pen Postcard. The one that says “I would have written sooner, but I just washed my Pen”. There is a lot of obfuscated info there. The pen was drawn over, scribbled over, but you can still pull some info from it. Like “I’ll Kill, Slayers, Emeritus, part of a bomb diagram, for a train railroad maybe?). Check it yourself if you don’t believe me. Zodiac wasn’t a fool, all of the misspellings were done on purpose. They used the false Harden Decipherment to their advantage, but seemed to get tired of it later. “Slaves & Paradice” is funny if you think about it. Paradice = Pair (two), two dice are called “die”. So “two die”, just like their M.O. There are a lot of people that work on this in their spare time. If they begin to think in more astrological terms they might get somewhere. First forget about the Harden Homophonic Substitution crap, because it won’t get you anywhere.
    Take Care,
    Matt Brubach

  16. Matt: in recent years, the Hardens’ decryption has been independently verified by a number of different state-of-the-art homophonic cryptogram solving programmes – these solve homophonic cryptograms without any prior knowledge of the letter assignments. As a result, your suggestion that the Hardens got it wrong – regardless of the specific intuitive / guesswork-based steps they took to get to that same end-line – does not now seem supportable.

    Davey B: looks like what I would call an “unintentional scam”. The Zodiac Killer ciphers are not connected; most will never likely be solved unless the author confesses all, perhaps in a letter or diary; some may very likely be fakes or hoaxes.

    Hence the probability that a single person has solved them all simultaneously without a super-sized portion of kid-yourself fries is basically zero, sorry.

    As always, I’d be delighted to be proved wrong, but I don’t seriously expect that to happen here. 🙁

    Nick & friends: The Z killer is, himself, now dead. His daughter went to the morgue in New York City (about two or three years ago) and produced documents and photographs to confirm the dead man’s identity. He is buried near his last home in Marin County. No, I have none of those documents ,to ‘back up’ my side of the story — much less my sister-in-law’s story and her daughter’s story.

    All of the so-called translations/decipherments/guessworks/puzzle answers are now buried with the Zodiac’s remains. I’m hoping you will, sooner than later, discontinue attempts to solve the ravings of a seriously damaged once-brilliant mind.

    Sooo….. the 18 symbol remainder @ the bottom of the 408 is not a Z cipher ?
    as it is not listed above as a authentic Zodiac cipher
    or you are guessing it is not ?

    Why are we sure the 408 is correct ? oh because it speaks in entire sentences and makes sense to what zodiac would say and the code key of it sort of makes sense ?

    Davey b: I’m just guessing. But I give my reasons for that guess, feel free to make your own guesses etc, I’m not stopping anyone doing anything. 🙂

    As far as the Z408 decryption goes, it is as correct as anyone can make it. There may ~possibly~ be alternative decryptions (i.e. plaintexts fitting the same homophonic ciphertext constraints): but given that cipher-breaking programmes with best-in-class homophone decryption algorithms find the same text that the Hardins did, the chances that any other decryption is equally satisfactory is dwindlingly small – by which I mean less than 1 in a million.

    Has anyone considered that there might be a pun in the name “Zodiac Killer” in the sense of *several* people in a ring going after victims in a particular order of the Zodiac? I know this must have been stated elsewhere, but what if we have more than one killer (more like a “Hunt Club” or “Surviving the Game” group of bored, dis-enfranchised specialists allowed to cause mischief as long as they did their government’s bidding at the end of the day, that would keep in form for more nefarious activities overseas by regularly evading the state-of-the-art police techniques at home as a matter of professional pride? One would have to be state level, one federal to coordinate and organize, and one in the media, to plant bogus clues. After that, you would only have room for at *most* six more — operating and coordinating across the map. This would mean a body count in the hundreds over the decades, and that the group was still open and operating today with promotion-from-within by deadman’s-shoes. Mess up, and the group turns and pirannah’s the erring member from within. An elite, organized, *never* for hire band of varying members that were — at one point — tighter than the freemasons who would have nothing to do with them for mutual disgust between the two groups. Not fear from either side — just dynamic disgust with each other’s tactics. No green berets, nothing romantic like that which would leave a paper trail — just men on the Vietnam Wall or other memorials already assumed among the dead. Nothing to say they were ever trouble with their superiors, or of a particular religious or non-religious belief. Just . . . seriously wrong in the head. Not even tormented about it like bad slasher-flicks would have you believe. With about 2k quiet, personal kills each before they would be able to even sniff at the possibility of being an official group member. No pins, no logos, no nothing.

    Just out there, doing their job for the corrupt arm of a military branch that needs a hit without presidential permission or oversight now-and-then.

    And nodding at other organizations in other countries that do the same . . .

    Speculating at this point.

    For now . . .

    Cat Darensbourg and all,
    I reread your posting of 19SEPT16 and I think that your idea of the killings being done in a ” Sign of the Zodiac ” order is very interesting. I, too think that there is a group of four people who are responsible. The “My Name Is …” Cipher seems to have multiple solutions that have led me to this thought.

  34. Brian Cameron on June 22, 2017 at 10:06 pm said:

    I have wondered if certain symbols like ‘+’ or ‘-‘ might be used to interrupt patterns in different ways, perhaps indicating that the method of transposition is changing through the cipher.

    For example, if you broke up the cipher into blocks of text between these two characters, sections that precede a ‘+’ symbol could be read left-to-right and sections that precede a ‘-‘ symbol could be read right-to-left.

    The Alberti Cipher from 1466 is an example of a cipher that uses certain letters (capitalized ones) to indicate a change in the encryption algorithm. The Alberti cipher uses such special characters to change the key rather than the transposition system, but is an example of a cipher with a similar approach as what I am suggesting.

    My above suggestion does not account for the places where you see symbols like ‘+’ and ‘-‘ immediately repeat or follow each other, though these could indicate a more complex system of transposition being used. Though, these double symbols could just as easily be a null or indicate the end of a sentence.

    I also wonder if the ‘+’ and ‘-‘ symbols could mean something like “the preceding character plus 1 or minus 1, so considering the symbols “O++”,

    if O decrypts to D, then you get “DEF” found in words like “definite” or word combinations like “made (any word starting with F)”.
    If O decrypts to “N” this would decrypt to “NOP” found in words like “unopened” or word combinations like “no (any word starting with P)”.
    If O decrypts to “H” this would decrypt to “HIJ” like in “hijack”.

    If you wanted to use a technique like this, you could probably make an effort to make use of such words/word combinations to make it appear more often than you would find in natural text.

    Obviously there are a lot of other ways you could use this kind of technique. For example, since vowels are very commonly used letters, perhaps these special ‘+’ and ‘-” characters only affect the substitution of vowels. So a + symbol might mean that characters that translated to “A” before the ‘+’ symbol translate to the next vowel ‘E’ after the ‘+’. After a double ‘+’, the ‘A’ would translate to an ‘I’.

    I also think it is interesting that many people seem to think that the fact that you can almost read “ZODAIK” in the last line that this is probably filler. The choice of some letter substations may have been made to specifically create certain desired patterns. In other words, the fact that the cipher contains some interesting symmetry of symbols could just as easily be designed by some combination of particular word/sentence choice, misspellings, symbol choice, etc.

    Above I am assuming that the ‘+’ and ‘-‘ characters are the only characters that are special in this way. I am just using this to explain the concept. Obviously, there might just be a single symbol or more than 2 symbols that affect the algorithm instead of being characters to decrypt.

  35. Brian Cameron: you may disagree, but for me the problem with complicated Zodiac super-systems (one might even call them “meta-systems”) is that there’s no real evidence that the Zodiac Killer was cerebral in that kind of way. There’s something a bit jarring about +, for sure: but it’s a long javelin throw from there to “HIJ(ACK)” etc, and so our time is probably better investing looking at the other letter shapes (of which there are many) and wondering just what is going on with the cipher at a very high level.

    As I recall, Alberti’s book merely says that the encipherer and decipherer should agree between themselves how often to shunt the rotor round: whether it’s every 5 characters or 3 words is up to them.

  36. Brian Cameron on July 12, 2017 at 7:40 am said:

    Thanks Nick for the comments. The Alberti cipher was the first polyalphabetic cipher and was developed in 1466. It was a precursor to the Vigenère cipher in 1585. There are a lot of websites that confuse the Alberti cipher, but if you read the Wikipedia page for the Alberti Cipher it quotes him directly and you can see how only lower case letters are encoded and upper case characters were the trigger to shift the cipher key. The Belaso cipher in 1553 was the first polyalphabetic cipher to change the key with each character.

    Claude Shannon in 1949 defined the Product cipher which was the first cipher to combine substitution and transposition ciphers in a complex way. So someone in the late 1960’s who was familiar with ciphers could easily consider their own approach without developing a complex “super” system. The fact that the Zodiac is known to have picked a Homophonic cipher system, a system that was last popular in the Middle Ages, could indicate the Zodiac did do some cipher research. Shifting the key once for every + symbol would require some innovation but is not a particularly mind-blowing leap.

    I have not spent any time analyzing the cipher to test this approach. I just thought it would be interesting to share some of my thoughts comparing the Zodiac and Alberti ciphers and considering how special characters could modify the encryption algorithm.

    I am not saying this The approach the Zodiac used, but a cipher using this technique could create ciphertext where a single character or handful of characters repeats frequently.

  41. whats missing in all this is common sense this revolves around the main person in this and that is “Larry Cane” no one else quite fits like he does. He was 15 in the late 30s when the movie “Treasure Island” came out and he derived from the movie the hood that he showed at berryessa the taxi cab scene that he copied with the taxi cab murder, the code he learned while in the Navy in 43 where he was stationed briefly no one else had the credentials of writing navy code because they weren’t in the navy or had that unique skill this separates larry cane from everyone else. Most aren’t aware he had a social life in New York as a young man before moving out west and went by the name larry kaye. The killing of Diane Null came about because he dallied in clubs in Vegas at that time and worked as a real estate salesman in between murders. He kidnapped this lady outside of Vegas killed her and threw her in a mine shaft. A highway patrolman stopped him and was aware of his dark eyebrow evil look about him and the fact his passenger had a ballcap over her face but was very still showing Cane had already killed her on way to the mineshift. All the goofy academics fall on their faces because they’re not dealing with reality the reality is he was two steps ahead because he did things ahead of time and by and large was very low key in the functioning dealings with others especially the ones he kidnapped.

    During the Zodiac Killer’s day, an older man signed a book that Robert Graysmith had written about the Zodiac and left it at Bob’s Big Boy Restaurant in Vallejo in a paper bag. It was left there for a young man who was quite interested in the Zodiac Killer. The older man drove a tan/brown Mercury with license plate number 3 888. Could this correspond with the three circles with an eight in each one that was part of the ” MY NAME IS … ” Zodiac Code ? If so, might the old man have been the Zodiac Killer ? A photo of the older man was given to someone known as ” Webmaster Ryan ” some years later. It was said to have resembled Larry Kane.

  43. I have a solution 4 340 would like u to look at. Not convinced it’s correct but I think it’s better than other proposed solutions. Need e mail to send it to

  44. The Zodiac was undoubtedly a musician. The code itself comes from characters of ancient greek music notation. Very few people would know what that is. Perhaps a gifted PhD candidate, a librarian or a linguistics specialist.

    Wondering aloud, Zodiac seems to give his own type of expiration when he discusses disappearing. His future murders accidental in nature. I do not believe he could live this life. Instead, I believe he could have had a terminal illness. In his accidental murder idea I think it not a stretch to wonder if he hoped for a continuing murder log posthumously. Just a thought.

  46. Just a thought on the last line of the 408 cipher. Normally this line is transcribes as EBEORIETEMETTHHPITI. I subscribe to the filler theory but I think there is a link here to the “concerned citizen” letter. There has been some debate if the “citizen” actually was the zodiac, and I think this last line might support that he was. For example in the citizen letter the strange polyphones for the Q, I and so forth that didn”t seem to match the harden code. Using the citizen polyphones the last line could easily be read as “BE OR WE TELL THE PIGS”. Here using

    (from the concerned citizen key)
    triangle = W
    Q = L

    (changed, errors)
    E = L ( the E is a polyphone in the citizen key but not mapped to L)
    circle with line = E(could be error, circle with dot intented which maps to E)
    I = G (no good reason.., plain error)
    backward K = S(error, should be normal K which is mapped to S)

    This last line could be a filler( used from a discarded encoding by the zodiac(possibly the ending of that encoding). Or of course the “concerned citizen” is not zodiac but someone that could have translated the last line to something similar as me.

    pLEASE IN THE SECTION OF ZODIAC CIPHERS i MADE TWO COMMENTS WHICH MUST BE DELETED, BECAUSE THE CASE IS STILL OPEN, PER LAW ENFORCEMENT. tHEY MUST BE DELETED AND i CANT FIGURE OUT HOW., cAN YOU PLEASE HELP ME ? iTS IMPORTANT, EBEORIETEMETTHHPITI – ITS 15TH CENTURY Dutch when they colonized Africa, It means “something is hidden” and I bet you can guess what with his ego. Thank you very much

    I see many questions on here I can answer. About him being a musician, he could play Organ and Piano very well. He played organ sometimes for the Black Temple. He played overture for Mikado school play with one of his victims. Voights response that the case can be solved with handwriting is wrong. Thats the problem They let him go twice because of handwriting. Hes a Multiple, I count 6 personalties, He can write 6 ways. The typewritten letters are always the female egos that protect him – Patricia Hauptz and Concerned citizen are their names, they do not exist. Then 4 males. No more room email me for any question about him or family. Thank you [email protected]

  50. Nick: Did you know Charles Dickens made his own tarot cards, I had no idea. He must have been into the metaphysical. Interesting information.

    Hi Nick ! I just wanted to let you know something. This chart
    * Z408 – 31 Jul 1969 – (solved)
    * Z340 – 08 Nov 1969 – cipher (unsolved)
    * Z13 – 20 Apr 1970 – “my name is” cipher (unsolved)
    * Z32 – 26 Jun 1970 – the “map code” cipher (unsolved)

    The Z408 is unsolved, its a double cipher like Z340. The second cipher contains his name in both case, full name missed by Hardens 50 years ago (I got it) and Z340 is missing the name as well and several lines. (I got the name) So honestly, there is no cipher really completely solved except what is in our own computers. They are serpent ciphers and they wind around reusing letters from the first cipher underneath. Hope I explained all right. His name has always been in front of us.

    You may not want to print this : It is completely true.
    Z340 did contain his identity only as a last name, cryptos said it was not there, but it was. It was a serpent cipher. It was in my twitter archive and Kevin from the team got it and claimed to FBI they solved it next day after the show. I can show you and send you the solve to prove it. David changed the copywrite date by backdating it. I dont know if he got the Z408 they will not talk to me. So basically it was stolen from Eric Buswala, my partner. 2016 was the year solved. But the Z408 contains full name. Kevin accused me of plagarism like 8 times and Twitter admin caught all of it and told me call the police. They did this to another man too. They are not honest people, sorry if they are your friends.

    I think I figured out the zodiac crosshair symbol. It is the symbol for the disability he has in one of his eyes. He has every single symptom. It would also cause lack of depth perception and affect gait. I am ridiculed for this in groups so I am not in any group. But try a patch on your eye and try to walk around after sitting, Try to park a car. I figured out from the skeleton card. This is his diagnosis and the symbol for it. ⊕ Horizontal and vertical orthophoria. And I think I am right on this, he wears special glasses. And other clues were under the misspellings. See symbol? Thank you.

    — Inspired by the breakthrough in the Zodiac case, investigators have already found success using the so-called “VLC Method” to solve other mysteries. For example, the famous Zapruder film of the JFK Assasination, when viewed in VLC Media Player, reveals that President Kennedy shot himself. —

    Hi Nick: Z died 6/5/22. They exhumed a victim in Fl for DNA and got it and it was a match. I have the memorial flyer with current pic. His house was sold, and the estate sale was 2 weeks ago. It was who we thought. He had a terminal illness and it was LE’s intention to “let time run out on him” Strangely, it was the same day he killed two of his victims, his very first ones if you dont count Cheri.

    But I wanted to ask you something, Do you consider Cicada 3301 to be a cipher ? Because I know the story behind it and who drew it. Its on my ex husbands first album. That was 1964. People think 2012 was when it came out, it wasnt. It was written by a conductor of an orchestra. His name was Markley. Thank you.

  56. New information in the breaks in the ciphers has been uploaded to my site page on FB/ZodiacCiphersSolved. Its a lot of information so I couldn’t post it all here

    The CIA later commissioned their Art Installation at Langley called Kryptos to be designed to use the themes from the Zodiac Ciphers to mask their continued operations. On my FB/CrackedKryptos page is the information about the K4 and Layer Two solves……mentioning a line from the plaintext – “Ol Wing Walcar”. The ciphers of Layer Two were designed in the same fashion as the Zodiac Ciphers, and 9 months later the “Scorpion Ciphers” appear, with the later Seito Sakakibara Ciphers following, tying them all together over a timeline until 9/11 and the Amerithrax Letters and their multi-layered ciphers.

    Take a look for yourself….Mr. Z has been busy

    Hi Nick, how are you? The remainder of Z340 has been solved. David broke to line 4 I went line 5 and the remainder, he coded this so simply. They didnt need to make it appear difficult to solve. I checked their work first, a few errors, nothing big. For example here is one line towards the bottom. One sentence says – “You’ll all be given back because now I ‘ve had enough of…….” . (thats just one line) It was so darn easy ! Z13 and Z32 was broken last year and approved by SFPD, Department of Justice, SFFBI. Now, I will turn in lines 5 to the end of Z340. Not kidding.

    Can we say this Nick ? Because I am kind of getting tired of wrong information.

    THE ZODIAC CIPHERS ARE JUST ANOTHER LANGUAGE, THEY ARE NOT CIPHERS.

    So many are just wasting their time, millions of dollars and hours trying to get a cipher solved and they are not even looking at the correct methodolgy. The way of thinking is in a box and viewed narrowly. People seem to have fell for the internet and TV mentality. Hey, if the Internet and TV says its a cipher, it must be a cipher !! You cant think that way, look at how many years people wasted because they were not looking at the big picture. Think critically and with an open mind. There is not one cipher, Zodiac couldnt cipher but he made you think he could !! Tricked almost everyone for 50 years.

    All Zodiac ciphers were was NOT ciphers. What they are is an iteration of arabic language. There are 37, He Has picked Hindi, Telugu, Tamil, Afrikaans. There are two ways of writing arabic. You simply use a google translator, drag and drop a line in there even Z13 and Z32 but you have to get the special char. Hit enter, it will show you the answers. The second way – send out to a translation company. Not one thing he did is a cipher. It should take way less than a day to do all of them. (I did not do Z63 because LE insists not done by Z. But it was) it is same language and Marianne Moore has a Mikado connection, he used that stamp as he did with most – they have Mikado connections. –FDR connection is obvious. They contain no secret data, just generalized data about himself, random thoughts etc, name is in Z408 and Z340 only. Z13 Z32 MAP are red herrings.

The most data can be found in Z340 lines 5-20 which were never done. There is an error in line 4 that changes meaning of paragraph.

  61. Nick may I( ask you something?? Its this. I really did solve the remaining ciphers 2 years ago. Tom Voight learned to change dates and timestamps, (kind of like giving a toddler a machine gun) he broke into my email (!) and ripped off dates, solves, anything related. Then it was distributed to the Hunt for Zodiac people – they both then backdated the solves I did and put a license on them all and claims they solved them. But they did not do the work, I did. Is there anything I can do to protect myself at this time? Law enforcement has had my answers for 2 years. Knight has already ripped off other work I did for the identity and said I plagarized and I did nothing but solve. He didnt. I let it go. Should I do the same again, or just let the work go. It doesnt seem fair to me ro work 3 years and only have theft happen. Thank you and if you can help with advice I would really appreciate it.
