I don't find anything in the evidence to actually disprove the scenario proposed by the defense. I was surprised they would come out so strongly with such a specific scenario, though, due to the unreliability of Casey's stories. I feel their scenario may contain elements of truth or on the other hand could be her latest confabulation. I did always think that Casey could have a compulsive "lying" disorder with a medical basis that could very well be completely unrelated to guilt. (In 40% of cases of compulsive lying there is a history of abnormal EEG, cns infection or illness, epilepsy etc. In other words, that her "lying" could be a brain or cns issue, i.e. memory dysfunction of some kind, or etc. And of course we know about her history of seizures and I've seen her also have what looked to me (in hearings early on) to be a rapid right-left jiggling of her eyes, which can be related to brain lesions or injury/illness. The more I read about these compulsive "lying" disorders the more i think the statements she made do fit with some kind of medical-basis confabulation because apparently it is very common for people who have confabulation to mix in elements of real memory from the past out of temporal context, like Casey did with mentioning taking Caylee to Sawgrass (where she really did use to go all the time in 2006 to see Annie, not Zanny), and working at Universal which she really had in 2006 etc. I also always wondered about the possibility of some kind of trauma disorder, which is exactly what the defense came out with. I was just surprised they went with such a specific scenario because of the apparent unreliability of Casey's memory/statements, and because so many other possiblities were never ruled out in my opinion. But if she came out strongly in the end with the belief that this was the truth of what had happened, maybe the defense had little choice but to go with it. MOO
