I feel the key to this whole tragedy is the topic of the conversation between Casey and Tony L from late 6/15 into 6/16. IMO, her hand was being forced (in her mind) between being a "Mom" to Caylee and the New "Casey Lazarro" which she was doodling about on a piece of paper found in her car. Casey wanted to start a new life with this guy, but there was one problem, Caylee. Tony L made it clear that he didnt want a child hanging around the apt., not because he didnt care about Caylee, but because he did and knew it wasnt a place for her to be. According to the phone records that evening and early morning, its obvious there was some type of "disagreement" going on, and it must have been deep to last all thru the night. IMO, the night of the 15th was the straw the broke Casey's back, when her Mom and her got into it....Casey more than likey wanted out of the house and FAST, and she must have confided in Tony L, but he put the brakes on her coming to his place with Caylee in tow.
The day of the 16th she is beginning to panic, that she is going to be stuck with her Mom and Dad forever w/ a daughter she never wanted in the first place, and will lose the guy she "loves". For a long time I was dead against the idea that the pool played a role in Caylee's death, but now looking back at everything, it seems to be the most simple and logical solution.....just as the place where she dumped Caylee, simple and logical. BUT, I do not think it was an accident. IMO, Casey either set up the ladder to pool on purpose so Caylee would drown, or she was in the pool with Caylee and drowned her herself. When she meets up with Tony L at the Blockbuster the night of the 16th, to me, it looks as if she is wearing a mens athletic jersey, the kind with open sides, and I would venture to guess a bathing suite underneath (dont think she would wear a bra w/ that shirt), and a hat.....like something she just threw on when she made her getaway from the house.
The Choloform searches I feel were just her being curios about why it would be used in dating, after seeing the comic on RM computer. I dont see her going thru the trouble of ordering it online or trying to make it at home, but she may have seen how "cholorine" can be mixed with other chemicals to create it. I feel the levels of chloroform found in the trunk are a combination of cholorine from the pool and other solvents used to try and clean the trunk.
IMO, the duct tape was used after she was already dead to try and stage a kidnapping. Casey came back to the house on 6/18 and I feel this is when she "prepared" Caylee to be disposed of.
Well thats as far as my theory has gone, I really cant pin point when Casey disposed of Caylee but I think it was sometime between 6/18 and 6/24.
Feel free to poke holes, there is always someone who will...I dont mind
