I am of the mind that something she was involved in was illegal and I suspect it was sexual in nature. JMHO of course.
Maybe she had to give her earnings to her *sponsor*
and that was the beginning of her lies. maybe she didn;t pay up and they took caylee until she could pay.
So, she wasn't all that worried because she knew they would care for her and she went out clubbing to raise money and everything went south from there.
Maybe she caused caylee's possible death, but didn't actually do it herself. Maybe she is believeing her own stories because she can't admit that she is responsible for caylee's possible death and wants her to be alive.
Just brainstorming people.
