Ok....here's my speculation on it.
It's weird that this pops up in the middle of a forensics report that has nothing to do with anything.
How about this theory. KC sent a letter to Lee A. describing exactly where she dumped the body. The letter is hand delivered to Lee via JB (possibly DC or JH). The letter is in the Hopespring house, it is shown to CA, she sends DC and JH on a mission to find the body on 11/15/08. Someone got a hold of the letter and photocopied it (maybe DC, more likely JH, maybe Mallory or even GA). They send the letter anonymously to OCSO and a person in the media (say Kathi B). OCSO calls KB and asks her to keep the letter quiet for a while (she complies cause she doesn't want her career going down in flames for one scoop). Now notice who JH went to with the tape....WFTV...legal analyst BIll Sheaffer. It all adds up, the only problem is proving it without seeing the letter.
That's my theory....tear it apart!
