I have a theory that really enlighten me when Dr. Spitz took the stand. I haven't read through this thread so I will apologize in advance if someone has already posted this. He testified that the tape had to have been put on after decomposition had already occurred because the tape would have stuck to the skin which would have decomposed and would not be present when he received the skull. In fact the tape was still present stuck to the actual skull. It then hit me. He was absolutely correct and it now makes sense. My theory about what happened from day one was that she wanted to make this look like a kidnapping or missing child case and hoped it would fall through the cracks, if they found the body, it would have been possible that the "kidnapper" had killed the child and disposed of her...hence the zanny story etc...so when Caylee was given too much chloroform and died, she must have panicked and didn't know where to put her, in the backyard at first, than in the trunk, then figuring out what she is going to do all the while the body is decomposing. She finally decided to put the duct tape before she actually put her in the final destination so that it was made to look like someone actually killed her. So, Caylee didn't die of asphyxiation and that is true, she died from overdose and the tape was the cover. Baez thought he had a homerun and mason made him repeat this several times but this makes it more obvious as to what really happened IMO. This means premeditation.
