We need two fences, don't we? One for the MFHP, and one for the disappearance of her stepson, Kyron.
If this is for Kyron, I'm a 6. I think she may well indeed be involved with his disappearance in some way, but THE ONLY THING that makes her look appear guilty at this time to me is that one email she mailed out on June 5 about the male chaperon. If that could be explained to her benefit then I'd be back on top again. Of course we don't have the evidence the GJ has, but apparently, even they are having difficult time deciding whether there's enough to indict her at this point.
As far as the MFHP goes, I don't know why, but I think she is at least might be guilty in that scenario. I think that's why she originally hired Houze to begin with. Now, whether it was something she ever was really going to go through with, I don't know. If she is ever charged, I think that will all come down to "intent".
