Also my memory is that they hadn't even processed the car when they got the apartment warrant so I'm thinking they saw something. Possibly her bracelet since it's not been mentioned in the searches and it's pretty big.
That's a very good point. You would think they would have detailed the bracelet in news conferences (unless they did and I missed it) and tell people to be on the lookout for it around town or on their property as that's the type of thing that would easily break off in a struggle or while moving a body. That makes we wonder if they've already found it.
