I find the "tradition" of wrapping the pets in blankets, plastic & tape and CA's dogs suddenly becoming ill and/or lethargic in March far too coincidental. I think ICA exacted her revenge on her parents by harming their beloved pets and then building up to Caylee.
That behavior usually develops in childhood and who else can a child exert 'authority over' more than an animal - all the better if it's loved by someone you are mad at... That doesn't mean I think she murdered every family pet but given what we know about her parental instincts I'd bet at the very least she contributed to the illness and/or demise of a few animals. Heck, she even blamed a few squirrels for her murderous actions.
In March (17th St. Pat's), (19th ICA’s b'day), (21st Friday night) she was pizzed at her parents again so she decided to start looking into ways to work around this little problem of no babysitter, not being able to go out when she wanted and “selfish” parents from whom she could inherit a house & life insurance if they should befall some sort of household accident.
She saw the “win her over with chloroform” MySpace pix and that gave her one idea… The One Tree Hill episode helped with the backup kidnapping story if anything went wrong… she started experimenting on her mom’s dogs with batches of homemade chloroform... took her several attempts before she finally got the formula correct (84 searches)... who knows how many times she may have searched for it (or worse) before March or on other computers that weren’t searched...
The fight/threats to take Caylee on June 15th and then on the 16th when CA wasn't available or willing to babysit that night… ICA decided that was the final straw and behaved exactly as she described her reason to LA on July 15th; "maybe I’m just a spiteful bi*ch"... (I can almost hear ICA on the afternoon of June 16th – ‘I’ve been calling you all afternoon because I have to go to work and need to know if I can drop off Caylee!!! (CA can’t or says no) Fine!! You want me to be responsible, earn a living and threaten to take her from me but when I need to go to work you can't be bothered with babysitting – surprise, surprise!’
Soooo…. MAYBE….
1.) ICA poured her entire homemade batch of chloroform onto Caylee's blanket, wrapped duct tape around her face & head & tossed her in the trunk. If the chloroform didn't kill Caylee the duct tape would or it would at least keep her quiet in case she woke up. In ICA's plan the duct tape also ties in well with a kidnapping scenario; if it ever comes to that... OR MAYBE...
2.) ICA placed the duct tape on Caylee & threw her in the pool (ties into her "borrowing little bits of truth" for the Caylee drowned & kidnapping stories – just not so much at the same time).... She pulls Caylee out of the pool, wraps her in a blanket, her batch of chloroform spills in the trunk during the rush to get out of the house or she pours it in there just for good measure.
I think ICA borrowed the shovel to bury Caylee in the swamp – not in the back yard, she drove down the street, realized/decided that was too much work to dig so she just left her. Although I wouldn’t put it past ICA to consider burying Caylee in the back yard but only as an added “dig” against her parents (Yet another thing I can hear ICA saying, ‘You want your precious little girl so much – well she is “close to home” with all of your other PETS that you loved more than your own daughter!’
.
I don’t think ICA carried Caylee’s decomposing body through the house. I think the decomp in the yard is from ICA jumping in the pool after returning from the swamp. Her OCD parents would absolutely notice mud/dirt tracked into the house & she was in too much of a hurry to leave. She either went into the pool fully clothed or stripped down in the yard (either way her clothes laid in pile in that yard for a bit). She went inside, changed clothes, returned the unused/clean shovel to the neighbor via the side gate, grabbed her dirty clothes from outside, tossed them into the trunk and fled (again). In her rush to get out of the house she left the ladder up & forgot to lock the gate.
Or... maybe I'm totally wrong about everything... would not be the 1st time and won't be my last.
