I, to have wondered if maybe Casey was washing her clothe due to them being in the trunk in her backpack and the decomposition transfered on to her clothe. (Didn't LE take some Clothe from her home with stains?) I don't think Casey dumped Caylee naked, I think that maybe she also had clothe in the trunk for Caylee and washed them at the same time at RM's house, and then dumped them after she washed them and learned the smell would not come out. Maybe that is why she made the comment to the FBH about the clothe not being found. Did LE ever check RM's house? The washer for traces of decomposition? I think it would be a great step for them to take, it's not to late unless the washer is no longer around.
I, also wonder if RM noticed any type of smell the day she came over. Maybe there is another interview with him or I may of missed him speaking about it. Does anyone know if he mentioned any type of smell when Casey came over? LE would of had to ask the question if he did not come out with it.
