FBI asks public for help breaking encrypted notes tied to 1999 murder, page 3

Thought I would post this as I didn't see it in the op article.

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.

I already posted the transcriptions. They're on this page.

The reason I was suggesting a few independent copies is because it doesnt look like it is 100 percent legible in all cases. Also, it looks like on the first note you missed the (AESM) on the first line.

Think I have a few differences than you not many. I left out the unusual spacing but all other distinguishing marks are there.

I get the feeling it is not a true code either. It is something made for reference for sure which is why it cannot be broken. SE could that refer to South End or South East maybe? I like your idea that it is a drug running list where only he knew his abbreviations.

According to members of his family, McCormick had used such encrypted notes since he was a boy...

Pretty precocious drug dealer, I suppose? I can't rule out your theory, but it doesn't seem to fit the profile of this guy, who was known to be into cryptography, at all. Plus, it's hard to imagine that after 3+ years no one at the FBI would have noticed if it significantly matched with drug codes.
