The FBI Needs You to Solve this Code

Two coded notes were found on the body of a man in 1999, and the FBI still hasn't figured out what it means.

Police in St. Louis, Missouri discovered the body of Ricky McCormick on June 30, 1999. The 41-year-old was found in a field and the only clue the FBI found as to what may have caused his death were two scraps of paper found in his pants pocket. The handwritten notes are 30 lines of numbers and letters grouped into several sections by parentheses and outlines, but after 12 years of trying, the FBI has called uncle. The best cryptanalysts in the country - from the Cryptanalysis and Racketeering Records Unit of the FBI and even the American Cryptogram Association - are unable to break the code, and the agency is asking for a little help from the public.

"We are really good at what we do," said Dan Olson from the FBI, "but we could use some help with this one. Breaking the code could reveal the victim's whereabouts before his death and could lead to the solution of a homicide. Not every cipher we get arrives at our door under those circumstances."

McCormick was a high school dropout, but his family says that he had experimented with codes and ciphers his whole life. The FBI believes that the notes were written not more than three days before he was killed, so deciphering them might point to circumstances of his death such as his whereabouts leading up to the murder.

Personally, I think the notes might be a suicide note from McCormick, but the FBI is more concerned with the challenge of cracking the code. "Even if we found out that he was writing a grocery list or a love letter, we would still want to see how the code is solved. This is a cipher system we know nothing about," Olson said.

It may seem strange that the best code-breakers in the country are stumped by a code that a high school dropout could devise, but solving ciphers is never a simple process. This story reminds me of the sculpture that resides at the CIA headquarters called Kryptos that holds similar lines of text [http://www.wired.com/threatlevel/2010/11/kryptos-clue/]. The artist, Jim Sanborn, assumed that the code would be broken within a year or two of the sculpture installation in 1990 but he's still dropping hints 20 years later so that the message is solved before he dies.

With codes like this, it sometimes helps to have a similar cipher for comparison, so the FBI has made the notes of McCormick available to the public to see if anyone has any clue or notion on what they might mean. If you have any ideas or know of a system that works like McCormick's does, write to Olson at the following snail mail address:

FBI Laboratory
Cryptanalysis and Racketeering Records Unit
2501 Investigation Parkway
Quantico, VA 22135
Attn: Ricky McCormick Case

And if this is just some crazy ARG designed to find the brightest codebreaker in the world and get him to Quantico to work for the FBI, well then, kudos. It's like The Last Starfighter!

I'm no cryptanalyst, but if I had to guess i'd say this guy came up with some kind of one-time pad. Those are supposed to be mathematically unbreakable unless you have a copy of the original pad used to encrypt it.

Dude just wrote random numbers to fuck with us. He is one good troll.

OT: I'm really surprised it hasn't been cracked yet. It's probably what I wrote earlier in my post.

Never thought the FBI could be stumped by a code. Can't they just digitize it and brute-force it or something?
there are several known ciphers which a brute-force search would take the age of the universe to break, even with the fastest possible conventional computers. This is part of the reason for the interest in quantum computing.

In my opinion this kind of thing is probably either:
1. A clever way to confuse the police if you murdered this man
2. It could be this guy saying, "if i'm going to kill myself, I might as well make the police involved confused as hell." *scribbles random letters on paper*

Troll physics.

I would minefield the whole scene with unreasonable amount of boobytraps.

I'm going to take a wild stab in the dark.

It's late, so I don't have the time to test my theory, but I'll put it on here in case somebody wants to waste their time. This I literally thought up seconds ago, so excuse the fact that it's almost certainly stupid and useless.

Okay, write A = 1, B = 2 and so on through the whole alphabet. Now under that line write Z = 1, Y = 2 and so on until you've gone through the whole alphabet backwards. Using these values, swap the letters around.

For example, the letter F = 6, so we look at the other line, where 6 = U. So replace the F with a U. Now do this for all the letters, and see if it's just as nonsensical as before.

(Tip) It probably is.

if the FBI hasn't cracked this yet, then it's probably gibberish. in my amateur opinion, there are way too many repeated letter patterns for this to be any kind of polyalphabetic cipher and a simple substitution cipher would be trivial to solve.

the dashed lines like "KLSE-LKSTE-TRSE-TRSE-MKSEN-MKSE" on the second page are particularly suspicious in how repetitive the letter patterns are.

Would take me a bit of time but the first note obviously states 3 points towards the main idea, followed by an address at the bottom. PRSE and NCBE are obviously acronyms Caeser shifted.

The use of brackets show that some things are observations not fact. Probably by using the RS and CB couplings you could re-create the note. I'd do it now but I'm a bottle of red down.

At a stab, RSE would stand for ING, given where it's used.
