What Chelsea said on Nancy Grace tonight makes the most sense to me than anything else that anyone has ever come up with. The only thing is I wish Nancy would have let her finish because I think she was going to bring up how Ron would be involved. I said this long ago and it just fits. If Haleigh overdosed on illegal drugs that Ron, Misty, and Tommy were all a part of selling then it implicates ALL THREE OF THEM! I think that she overdosed on the pills and then Tommy and Misty got rid of her body so that they didn't get implicated any further. I think that Ronald Cummings was at WORK as it has been said all along and it fits with everything but he would still be implicated because he sells the drugs. This explains his stone cold expression while walk out of the jail house after being told that it's a homicide investigation etc. He already KNEW what happened and was not mad because it was an accident and I guarantee that the grandparents know too. Also Crystal said this from DAY ONE that she wondered if Haleigh got into pills. I think that they got rid of her body to save their drug dealing asses. JMO ETA: Just want to add to that obviously no evidence of drugs were in the home but they probably could have taken those along with Haleigh's body to the river that night. The pills would have dissolved in the water.
