I think that they already did. Back in July 2008. August at least for CA. GA probably did so much later. Likely, October...I take it they haven't played the voice message yet. So basically, trying and badly, to think like the A's, they likely believe that KC disposed of Caylee, but only after whomever did whatever to her. The whomever is anyone in their cross hairs, Tony, Kronk, Jesse, Amy, whomever. They know too much to know that Caylee was definitely in the trunk of Casey's car. So they must explain this away by saying someone else did it. Jesse or Ricardo or whomever...and Casey only merely covered up by hiding her body. Geesh.
