I think they might be referring to the huge report from this fellow, Andrew R on page 62 of the Florida Department of Law Investigative Reports. I don't know when it was dumped ... maybe today ... I have it on a PDF. http://www.cfnews13.com/uploadedFiles/YES 4901-4962cellphone_misc_redacted.pdf
LE had a profile ordered on him as well.
I don't think that could be the same letter.
The letter in question here was mailed to LE, from "an unknown person." Also, it was addressed to "Lee."
The letter to which you are referring was mailed to the governors office and addressed to quite a few entities, including the governor of FL, the Attorney General, several news stations, and even NG, among others, but not to "Lee." Also, it was from Andrew R. and not an unknown i.e. anonymous person.
