I know, dodie, the whole mess is crazy, but look who and what we're dealing with! The only thing I would bet the farm on is what I bolded from you above. There is NO WAY (in my opinion) that RC disposed of Haleigh. I can see him doing everything and anything, but he would have to have someone else do that task for him.
IF thats the case I feel certain he or someone in his family made the arrangements to have Haleigh's remains disposed of in a manner that would never reveal the cause of death...And for me ONLY two scenarios come to mind...JMHO
