I posted this in the theory thread but think it also fits into the search and whats happening so I'm posting it here as well.
Since Misty had been on a 3 day binge and didn't want to babysit that night, maybe Ron gave Haleigh something before he went to work to get her to sleep, since Misty was recovering from her wild weekend. Haleigh got sick, vomited or peed her blanket, Misty was calling Ron telling him. GGS came over to try and help. Haleigh died, they didn't take her to the hospital because they were illegal drugs and Ron gave them to her. Maybe she tried giving her CPR, which is what junior saw the couch bouncing, Ron called Tommy and had him and Joe go help dispose of Haleigh, probably threatened them if they did not,they put Haleigh and blanket in a garbage bag and throw her out at the dock. Ron stayed at work for an Alibi and stopped at the store on the way home because he knew it had a camera. Ron tells Misty we will say she was kidnapped, he flushes or gives Tommy and Joe the druggs he has at the trailor used on Haliegh. They are all involved I think possably Timmy to.
Tommy started going down hill along time ago, I think he was going to crack way back then and thats the reason for the rat thing. I think Tommy is the weakest link and he now gave it up, they confronted Misty and told her they know what happened and she thought they were bluffing so they took her to the scene to show her and try and get her to talk.

I think he is very involved, I think he told Misty not to take her to the hospital, I think he called Tommy to go help Misty get rid of her, I think he probably got rid of all the drugs when he got home and continued the lie. So with all that he would be charged with, Accessory, destroying evidence, filing a false report, endangering the welfare of a child, neglect, the drug charges and possibly involuntary man slaughter. Plus he knew that he would lose junior to Crystal so he still would have been looking at LOTS of jail time, so he figure he had an alibi as long as he stayed at work, and no body they could claim kidnapping.
Oh Lord I hope I didnt give someone something plausable to use as to what happened
