I have always felt Ron Cummings was involved in illegal drug activity and somehow his involvement with illegal drugs, led to Haleighs disappearance and demise. Its karma that Ron was caught dealing/selling drugs to an undercover police officer almost a year after Haleigh disappeared. As for Misty, she got pretty cocky shortly after Ron proposed to her. She had that Cat that swallowed the Canary look about her like she was getting away with something, pulling the wool over peoples eyes which she is still trying to do. IMO Ron was controlling Misty by supplying her with Drugs to shut her up. Ron Cummings seems criminal smart. Now that Misty is " sober" I will bet Ron is scrambling to make deals with the police. This time Ron " drugs will not set you free," but maybe it will get you locked up away from society for a long time.
