Two thoughts....
RE: Chloroform in the trunk
It was generally discussed in the early stages of the case upon the release of forensics supporting an elevated level of chloroform that stain removers, etc. utilize chloroform. More recently another poster suggested, yet I haven't seen much else of it...BOTH the elevated level of chloroform in the trunk AND at least one of the cadaver dog alerts in the backyard would possibly be explained by Cindy using her Bissel steam cleaner and some spot remover on the trunk. That poster suggested Cindy dumped the resulting water in the backyard, hence, the cadaver dog alert. I am liking this proposal more & more over time. I'd add to it that IIRC, the portion of the trunk that was stained was the removable mat over the spare tire, hence, the whole mat may have been taken to the backyard and cleaned there. As JWG has offered in the computer forensic search, chloroform searches on the PC in March may have been completely unrelated...just maybe...
This opens things up more for the use of other medications resulting in the o.d. of Caylee. Sadly, owing to the slow-acting nature of the OTC's Casey might've been accustomed to using...Casey may have applied the more-is-better principle since she would've been trying to be covert about Caylee being in the car. Furthermore, if Caylee was just drowsey...and not 'knocked out' by the Rx...the duct tape with the heart sticker may have come into play to enable Casey to get back to the apartment before her protracted absence became suspicious. As another poster suggested...the heart sticker made light of the situation and helped Casey forgive whatever guilt she might've felt, even if ever-so-briefly, for her actions. If Casey had been smokin'/drinkin' that afternoon and in a hurry to get back to the apartment...obviously exercising ueber-grossly poor judgement and negligent behavior...the tape getting caught in the hair would just be a detail she'd handle later...I mean...it is 10-min-@-time-Casey, right?!?
FWIW, IF...big IF...as she commented to Amy in texts, Casey had a bruised rib in May whilst she had the flu/cold. Casey commented to Amy 5/21 about having anti-inflammatory Rx to treat the flu & bruised rib,
"Works for me! I'm not feeling worse. Found out I have a bruised rib. At least I have nice pills for my flu and Ill be popping anti-inflammatories like theres no tomorrow.". So...who knows what Rx Casey had in her purse. If she'd used OTC's to speed/extend Caylee's naps...maybe she just upped the ante w/ her own Rx on a spur of the moment decision when her 'flurry' of calls finally failed...7:20PM.
RE: Casey-think factoring into a few things...(e.g. the duct tape in hair, "spiteful b*tch", revenge/victim motivating her hasty/poor decisions)
Recommend watching the last released August Casey w/ G&C jailhouse video again...and the ramp up between Casey & Cindy. Cindy forces an issue => Casey's defense/distract/deflect mechanism kicks in...and Casey immediately becomes the victim..her actions are justified in her own way of thinking because, after all, she's the victim and no one understands...:furious:
Now...replay that sequence of behavior considering the last call Casey made to Cindy 6/16 7:06 PM that lasted 1 min 24 seconds. Cindy forced the issue of Casey becoming responsible for her daughter that night => Casey's actions become justified in her own mind. Last ditch attempt to Amy 13mins later...perhaps after the last dose of Rx has already been given...just gonna drop a drowsy/sleeping Caylee of with her, right? No luck...and the furious Casey you saw in that jailhouse video pulls out the duct tape. The state of mind you saw in that video is the state of mind she was in when that duct tape was applied...she was effectively in a rage. :furious: The heart sticker, in effect, to relieve her own guilt...IOW...directing the thought @ Caylee...this is Cindy's fault...not mine...I [Casey] love you [Caylee].
Casey writes, "Diary of Days" directing the first half-to Cindy.
"On the worst of worst days...Remember the words spoken" = 6/16 7:06PM phone call. IOW...when you find out Caylee's gone, I [Casey] want you [Cindy] to remember that I [Casey] called you [Cindy] for help, and you[Cindy] refused to help me => This is Cindy's fault...not Casey's.
"With great power...comes great consequence"= You [Cindy] thought you had the power to control me [Casey] through Caylee. And see what happened! This is your [Cindy's] fault!
"What is given can be taken away" = I [Casey] have the power. I [Casey] gave you [Cindy] Caylee, and I [Casey] had the power to take her away.
The second verse, Casey directs to herself...
"On the worst of worst days...Remember the words spoken" = Remember...this is her [Cindy's] fault...not yours [Casey's]
"Hold your head high, smile, laugh...tomorrow is a brand new day" = Remember...this is her [Cindy's] fault...not yours [Casey's]. Keep your [Casey's] power over her [Cindy]. Enjoy your [Casey's] life...otherwise, Cindy will have the joy of seeing you suffer from your own actions...can't let that happen at all costs = No admission of guilt...ever.
Since, IMHO, this line of thinking was powerful enough to fuel the murder...its certainly powerful enough to keep Casey from ever admitting to the crime..and giving Cindy the final/last victory.
