We know there was a head, arm/hand, and leg/foot found so far. I wonder what else was in the bags? I would think those things would be able to fit into one bag. I wonder if these were obviously identifying parts? Obviously her head would be. But I wonder if she had any tattoos on her foot/ankle or arm/wrist? If so, I'm thinking he put these identifying parts together and tossed them thinking that the garbage would go out and nobody would find them only to put them in the most unlucky trash can.
IMO there was not huge mess in her home. I don't see that being reported anywhere. What I did see was that there was blood found IN THE DRAIN which I'm sure means he cleaned up. I'm fairly certain her mother would have at least canvased the place before she called police and it seems no obvious crime scene was noted as her texts to JC did not elude to anything other than her being missing.
also in the drain was body pieces....so he at the least tried to wash down SOME evidence...but leaving the SAW there in the bathroom, as reported is kinda weird....not trying to put that back where he found it, or disposing of it...wonder if he just missed putting that back or disposing it?
