My only interest in these letters is who's behind them and what's their motivation.
Is it someone who has followed the case (print news, HLN's, internet/forums, etc.) and is sympathic to Misty, infactuated with her, or perhaps sympathetic to Ron & family and simply wants wants to breathe new life into the Griffis/Sheffield family abduction theory...?
Perhaps just a sympathic fellow inmate and/or one that sees $$ in exchange for some creative writing...?
Maybe Chelsey helping Misty reinvent a story to keep the focus elsewhere, or TN, knowing that the more focus/pressure on Misty, the greater the risk that Misty might flip on Ron (or :waitasec: her)...?
Whoever it is, one thing is certain - LE knows who it is. If it's simply an over-involved online self-injecting sleuther or a fellow inmate, then they'll simply disregard the questions/comments from, say AH, and find it amusing that Misty would even think, for one moment, that anyone believes she wrote these words and/or this poem/song.
Now, if it's a case player - that's a whole different matter and one would think that LE is/will be watching this exchange very, very closely.
The mention of $$ leads me to lean toward it being a fellow inmate... JMO ~
