FBI Wants You To Solve Encrypted Notes From Murder

coondoggie writes "The FBI is seeking the public's help in breaking the encrypted code found in two notes discovered on the body of a murdered man in 1999. The FBI says that officers in St. Louis, Missouri discovered the body of 41-year-old Ricky McCormick on June 30, 1999 in a field and the clues regarding the homicide were two encrypted notes found in the victim's pants pockets."

      In all seriousness, though, it would help to have these additional details:

      McCormick was a high school dropout, but he was able to read and write and was said to be “street smart.” According to members of his family, McCormick had used such encrypted notes since he was a boy, but apparently no one in his family knows how to decipher the codes, and it’s unknown whether anyone besides McCormick could translate his secret language. Investigators believe the notes in McCormick’s pockets were written up to three days before his death.

      Over the years, a number of CRRU’s examiners—who are experts at breaking codes—have puzzled over the McCormick notes and applied a variety of analytical techniques to tease out an answer. “Standard routes of cryptanalysis seem to have hit brick walls,” Olson noted. Our cryptanalysts have several plausible theories about the notes, but so far, there has been no solution.

      To move the case forward, examiners need another sample of McCormick’s coded system—or a similar one—that might offer context to the mystery notes or allow valuable comparisons to be made. Or, short of new evidence, Olson said, “Maybe someone with a fresh set of eyes might come up with a brilliant new idea.”

      I think the code was probably meant for his eyes only, which means he probably constructed it using abbreviations and codewords that only he himself would understand. Without knowing those, well...good luck.

He didn't spend a great deal of time making it "right" before committing it to paper. It looks blocked 5-4-3 or maybe 5-4-3-2. There are no single characters so either the messages were fixed length, it's salted with characters to make it fit the fixed length (most likely imho) or he was way careless in spacing.

      for example, imagine on page 1, i wrote "TISAILGTCFDU" and on page 2 i wrote " ESTANOAOOFEN" Now, each of those pages alone are useless. this reads decoded 'TESTING CODES IS A LOT OF FUN" It is done by writing the first letter on the first page, going to the second page, looking for your pen mark, and writing the next letter, then returning to the first page, seeing your second letter as though you would trace it, and writeing the third letter after it, leaving a space between the first and third letters. You finish a line across the pages, and then continue the phrase, this time filling in available spaces left in the previous lines. the result is a garglemesh of letters. If you did this, and added random word breaks, you have a coded message on multiple pages that reqires both of them to decipher a readable message. if you know how to look at it, you can hold the two pages up to the light, put one line above the other, and read the message with a little effort.

      A code like this is its own codex, and relies on the entire message being available to decrypt it. I've played with the images the FBI provided in photoshop, and don't see that this is exactly what has been done, but I figure that whatever sort of code it is, it had to be easily readable/create-able for this guy, and could easily rely on some physical form of cryptography like i demonstrated here.

  90. Some ideas by Celarent+Darii · · Score: 1

    It does seem to be written from left to right however, as the text is mostly flush to the left margin. If it was written from the right to the left, usually people make the text flush from where they begin writting.

    "SE" definitely looks like a space or some token marker, perhaps a shorthand for "Stop. End" like a telegraph.

    As a kid I was fascinated by two kinds of cyphers, such as the "Tic-Tac-Toe" cypher where the letters would be put into a grid and you used the grid shapes as keys to the letters, basically a substitution cypher. A variant could be made using some well known secret word or phrase that provides the key substitution. Subtitution cyphers can be broken using frequency analysis, which is the first thing you can check with the computer. If it were that easy they would have solved it by now.

    He seems to correct himself in the middle of writing (for instance see 3rd line of 2nd note, where he corrects the 'T' into an 'R', and on the first note where he corrects the first letter of the second line). This makes me think that it is more than a substitution cypher but something perhaps he counts from a certain letter to get the next one (it's easy to make mistakes counting if you are thinking of the thing you want to write), or that his key could easily miss from one letter to another. The difference from 'T' to 'R' is not very far away, so he could have miscounted in applying his algorithm.

    The fact that there seems to be some delimiting symbols ('SE' is a marker of some sort) means perhaps that the algorithm had some kind of break points where to reapply. If it was a simply one-to-one correspondence he probably wouldn't use two letters for substitution of a space. It might be something simple like removing all the letters but the first and last (SpacE), with spaces following the same rule.

    Also there are some lines that are very similar, for instance (3rd to last lines of 1st note):

    (cdnseprsednsde74ncbe)
    (prtseprseonrede75ncbe)

    They only differ in a few letters, namely CDN -> PRT; DNS -> ONR and the two numbers. If the message was an address or describing something with numbers (a car model year for instance) then there could be clues for trying certain transformations.

    The fact that the encryption doesn't seem to encode numbers might be significant. If it were a sort of rotating cypher, where each letter is substituted and then counting from the last letter the next substitution, normally you wouldn't include numbers as then it would be difficult to subsitute past 9 (at least for a boy who doesn't know modular arithmetic).

    The fact that he corrects himself so often in my opinion means that the encryption is something more complicated than a simple one way substitution. If he used it for a while there would be less errors (after awhile using substitution cyphers you almost automatically write v for e or whatever). It seems to be some kind of rotating count where errors are more prevalent.

    It would really be helpful to have more examples of his handwriting and to know more about his personal habits. Breaking passwords is also more often trying to guess what a person was thinking at the time than actually trying symbols (at least when a human tries to decypher them). I wish the FBI would release more of his writing, especially his unencrypted text as that would give hints on his spelling habits and level of education in general.

    Look at the E, note that it seems to be different in different places, the middle line is short, offset left, offset left and the right half is longer than the top or bottom, etc. Some E's look like a C with a middle line, some E's have a top line longer, some have the top line angled up, etc So with just that you can make a matrix of the differing E's and assign each an identifying symbol...

    Now about the R, notice the solid vertical left line in one, the dual left line forming a vertical oval in another, the top loop being tilted up or down, etc.

    Maddening isn't it?
