For her it is all about control and power. She has a lot of power here and she knows it, too. She has the whole country listening to her lies.I may be wrong, but I think Caylee was moved a couple of days after her death. I don´t know where Casey hid the body, but it would have been close to the house - possibly in the garden.
Caylee was dressed, but there was nothing to stop the spilling from her face.
Of course I don´t know what happened, just my theory. I wish that little b**** on trial would tell the truth for once!
Also re: Caylee was dressed. it has also been said that she had either a diaper or a pull up on so that diaper material would have at one time contained the adipocere.
