Honestly, I don't see how anybody can be sure of anything in this case. Maybe that's why LE hasn't filed any charges...they're not sure either? Considering that Misty was offered immunity, she doesn't appear to be the perp, but that offer is no guarantee. I have a real hard time picturing LE playing over 2 years worth of head games in an attempt to get Ron to slip up, so, unless they've sorely underestimated him, I don't see him as the perp either. Personally, I think Tommy's the perp, but him not being charged, has me wondering about that. I fully expect murder charges at some point, and won't be surprised to see all 3 of these people, (& maybe more), charged in various degrees. They've all 3 reportedly failed LDTs & they're all 3 locked up, seemingly in an attempt to sort out who did what. Until LE straightens this mess out, I'm not willing to rule out anybody or anything. MOO.
