I've always though the seeds of premeditation in this case, was Casey planning to rid herself of her parents. Scenario A IMO. I think the plan was to stage a home invasion where neck breaking might be featured. In any case, bruises and cuts all over Casey could be explained in this scenario as being defensive wounds. She could say she was the hero who returned home during the attack and scared the perpetrators away.
Chloroform would fit nicely into this fantasy too. If she staged an early morning invasion. She could have used it to sedate George and Cindy, possibly to death in their beds. In any case it would be easier to break an unconscious persons neck, than a conscious one. There's no way Casey fueled by hatred could have successfully brought down either of her parents without restraints. (a recurring theme) So I believe she was prepared with her duct tape months before she used it. The parental units would have adrenaline fueled self preservation mode strength working for them and Casey knew it. She'd had years of experience bringing them to that edge.
I imagine the life insurance payout from Cindy's employer under violent/ accidental circumstances alone, would be motive enough for Casey. Plus, she'd get the house.
Caylee was an afterthought. Because Cindy, fed, clothed, mothered, nursed, babysat, spoiled and financed Caylee, Casey had no clue what it took day in ,day out, with consistancy, to be a mother. So in her mind, it was all going to be cool. Amy would babysit, whatever.
Then the s#*t hit the fan because of the theft from her grandfathers account. Her mother was outraged, and rightly so and Casey stomped out in self righteous indignation, like she always had before.
Only now, she had the snot face in tow. I mean WT*. She didn't even want her anyway. Her stupid %&*# of a mother did. Besides that, a tired, hungry, crying Caylee was probably screaming inconsolable for CeCe from the back seat.
So Scenario A was modified into Scenario B and it was turned on Caylee. Casey never wanted her anyway. Losing Caylee would probably kill her parents anyway and almost did if the A's suicide disclosures are true. I mean %#*&@ them. Plus TonE only wants boys. (Anyone else think if Casey had a son, TonE would have told her he only wanted girls? LOL!)
She was practicing killing her parents when she gave George the 'mini stroke'. It was just a matter of time.
I don't think she could sit in jail wrongly accused on a whim of things she did not do and would never do, without a pen or paper unless she was completely immersed in fantasy. I'd be on the psych ward in restraints by this point if I were innocent, wouldn't you? I get depressed even thinking about it.
MOO
