In asking about the shoes, the other day, it was because the testimony of the computer store guy came to mind. If indeed he did see Casey with Caylee lagging fairly far behind and one of the two looking angry, at one of the big box stores at around 4:00 PM on June 16th, 2008, then perhaps Caylee had a potty accident in the store and Casey changed her clothes, with the backup clothing, in the car and left her shoes to dry out. But, instead of putting Caylee in her car seat maybe dear old mom was in a hurry to get to Tony's and having no one to come to her rescue for babysitting just put Caylee in the trunk, chloroform, duck tape and heat of June. Then, later when she checked on Caylee she was long dead.
Now, what to do? Drive around with her in the trunk until she figures out a good complicated plan...ah, she was abducted and kidnapped and because I didn't comply they kill her and leave her to rot. Now, to make it really look like a murder.
Now, for the Big Question: Did she plead for Daddy to give her ideas, to help her out of this horrible jam and maybe to dispose of Caylee for her?
Was it her/their intention for Caylee to never be found or did she/they indeed enlist the help of RK to "discover" the remains after most of the evidence was destroyed by the elements but would still appear as a murder by Zanny and Company?
If Daddy (GA) did help her out of this jam...it would seem more likey and in light of this new witness, that it was after the fact when he felt it was the only way to keep ICA from the DP. It would seem that she may have said something to make GA feel sympathy for her...like Caylee accidently drowned or suffocated in the hot car and that ICA didn't know what to do and now (by then) it was too late...no one would believe it was an accident. I can't see GA going along with it from minute, even day one or two, if he honestly believed it was an accident.
