Yes, that's very disturbing. I've stepped over into the premeditated camp (explained in an earlier post) but I do have to say you would think if Casey were planning a murder she would have had a better plan to dispose of the body.
Still, she is a narcissist and a sociopath, and I have to remind myself they don't think like the rest of us. They are "magical thinkers," as in "Casey's imaginary friends." She probably just figured, like Scarlett O'Hara, she'd "think about that tomorrow."
I think she was thinking about a “solution” to her dependency..I think she thought about killing her parents, too...but planning wasn’t her strong suit...as in body disposal planning when Caylee was dead...as in how she was going to keep it hidden from her family that Caylee was dead...
Short term solution to a problem of the day landed her on trial for murder.
Her lies to her friends, to her parents, and to herself are simply astounding.
She is one cold cookie .
