I'm beginning to think we have to look at things a little different. I kept thinking he was stupid to throw bags of trash away in Hartford and to have his phone with him during it. Maybe that's a ruse. What if he knew he'd be tracked and seen. Why would he do that? I don't know but assuming he did kill her, he did a pretty good job of hiding the body. To me, that means part of his plan was to be seen throwing away those bags.
Think about it. If all that was in those bags were some bloody clothes and sponges, why not get rid of them with the body, burn them, bury them. Any one of a hundred ways of disposing them. But no, he chose to dispose of them publicly. At first I believed it was because he was stupid. Now, I'm not so sure.
Also, I believe LE said the trash was sponges and HER bloody clothes. That doesn't make sense. Why would they undress her after killing her, then throw the clothes away. So maybe the clothes were just some stuff lying around in the garage that they used as rags. Makes me think that the trash with her blood on it has nothing to do with her disappearance.
Ok, pulling at straws here, but assume he knew what he was doing, and that he didn't make a mistake. What would that mean?
