Considering that we don't have a whole lot of information, it's impossible to be 100% sure of any one theory...so, I have different theories, for each of the main players. 1 Tommy, has over and over again, put himself at the trailer, supposedly failed a LDT, and then told a horrible story that put him in the thick of the action, so, he's my main suspect. 2 But, Misty isn't in the clear either. She had a wild weekend, and according to witnesses at the bus stop, she looked worn out, and smacked a little boy across the face. IMO, it's not a stretch, to imagine her pulling the car over, a few minutes later, and beating Haleigh with a board, or whatever was handy. But, for this theory to work, Ron would have to cover for her...which I think he's capable of. Maybe Haleigh was injured, and insted of seeking medical help, Ron left, and Misty put her to bed, where she later died. 3 Ron has never been upfront with his work hours, and considering that work is his alibi, that's suspicious. I've heard that he got to work early, worked overtime, worked an 8 hour shift, and everything in between. If his alibi was solid, IMO, he would have been shouting it from the rooftops. After the numerous calls to Misty, him stopping for cigs and beer, doesn't add up. 4 He admitted to calling Tommy, looking for Misty, so where did he think she was? Where did he think the kids were? He admitted to asking Tommy if Misty was with him. So, was he ok with the kids being home alone? He said he was surprised to find Misty up and awake. How could that be? She admitted to trying to call him, and as far as I know, he never denied it, and cops have the records, so one way or another, one of them is lying. Because of the beer stop and the convenience of the video cams, I think it's likely that Ron went home and then left, to establish an alibi. What did he do, while at home? Where was Misty? At one point, she said that when she opened the door, she asked him if he had Haleigh. He did not say, ' You never said that'. So??? Also, IMO, the most damning evidence pointing to Ron, was Misty's failed LVA question pertaining to his involvement. That's huge, IMO. 5 Add that to her 'dream' of 3 or 4 men, and there's a problem. 6 CS thought that Haleigh's attendance was significant enough to bring up, and she knows Ron pretty well, so IMO, it is significant. Add that stress to Misty's weekend, and her not wanting to babysit, and Haleigh being more than she could handle, and I see potential motive. 7 Ron married Misty, at a time when a normal man would have been contemplating murdering her...so, I'll never believe that he didn't want her bad enough to go to extremes. Yes, they were separated right after Haleigh came up missing, but we never heard whose idea that was. It could have been Misty's...even if it was Ron's, it didn't last long, and then he married her, for crying out loud. Anyway, these are a few of my suspicions, of these people...sorry my post was so long. JMO.
