I do think the the most plausable explanation right now is that
Casey and her parents had been fighting
Her parents had had it with her lying, stealing, freeloading, lack of responsibilty etc
Casey leaves or gets thrown out and takes Caylee
She uses Caylee to get back at her parents, and probably kills her for the same reason.
At first her parents are accusatory, but then jump on board with Casey's lies.
Why, because they are in denial and down deep feel guilty that his happened, maybe feeling that if they hadn't pushed Casey, Caylee would still be here.
JMCDAD, I'd like very much to agree with this explaination. It seems so logical. She takes her child away as punishment to her parents. But, we don't know the background on the relationship between Casey and her parents. Perhaps this was a common occurance. We don't know if there were other times in the previous months that a fight between Casey and her mom and/ Dad ended with Casey storming out with Caylee in tow. But, she returned later. If this behavior happened often, maybe George and Cindy weren't too alarmed. They expected the pattern to be repeated.
Guilt? Yes, you are so right, the grandparents were buried in it. That would lead them to lie and try to cover for Casey.
Just adding another "maybe" to this strange case
