Fooling around with the car seat or cover also makes sense in light of something else CA said in her depo. She mentioned wiping the "mama" dolls face, which was found in the car seat. That doll is cloth she said, but has a plastic face. She mentioned she did it because it was not as clean as she thought it ought to be. Yeah. Right. She comes home with the Deathmobile and takes out a steak knife which she quickly washes and returns to the box under the silverware, removes a pair of KC's pants, which she washes (and which could not possibly smell like smoke after being in that car for two weeks, they would smell like a dead child) and takes the time to wipe a baby doll's face. Everything else she just takes out and sets aside on the cooler.
And she does all this before she can even locate her daughter to find out what happened. And before she decides to return to work to give the appearance that she and GA are not tampering with what they both know is evidence.
I find it odd as well that her car seat is stored in the attic; that garage is full of items on shelves, like the pet carriers, and items at least as large, like coolers.
If LP is right and they replaced the washer and dryer, they'd better hope they replaced the hoses on the vacs and the wetvac.
And if people's speculation that something physical happened to Caylee in the carseat is true (and the missing tooth is an indication of foul play), then perhaps that is another reason, in addition to the duct tape, that allowed Dr. G to establish Caylee's death as a homicide.
Somebody needs to tell CA that telling a half truth is the same thing as being half-pregnant.
