For the most part, I've tried to stay away from forming any theories regarding what I think happened. But the past 2 days, I've found myself wandering more and more into that territory. Last night, I landed on a string of thoughts that made perfect sense to me.
Why would you chloroform a child, duct tape her mouth, and possibly her hands as well? If you are going to kill a 2 year old by smothering them with duct tape, why would you need to make chloroform (not an easy process) and use that to subdue them. Cough syrup would work just fine. That's a question I've come back to every single time I've tried to figure out what might have happened here. The chloroform searches were done in March. Caylee died in June. You don't click on a recipe for chloroform 84 times to learn how to make it in March, and then actually make it (not refreshing your memory on how to make it) 3 months later. I believe ICA actually made the chloroform in March or early April. So, if Caylee didn't die until June, what was ICA doing with this chloroform?
We know that there was a loose hair with a death band found in the trunk of the car. Caylee's body was triple bagged. How did that hair end up loose in the trunk of the car? How did decomp fluid leak through 2 trash bags and a laundry bag with waterproof liner, onto the liner of the trunk itself? I don't think it did.
I think ICA was using chloroform as a "babysitter". She wanted to meet up with TL the night Caylee went missing. There were numerous rapid calls to GA and CA late that afternoon. ICA couldn't find a babysitter, imo. She chloroformed Caylee, duct taped her mouth to keep her silent if she woke up, possibly bound her hands with duct tape so she couldn't remove the mouth duct tape if she woke up, and put her in the trunk of her car. Later, she goes to check on Caylee, and Caylee is dead. This fits with both Dr. Vass' and Dr. Hackett's testimony regarding the body being in that trunk very close to time of death. It also fits with why we might find a loose death band hair in the trunk (she's not bagged), and decomp fluid on the liner.
So, if Caylee died in the trunk of the car, why do cadaver dogs hit on the backyard? I didn't have a clue. Until I recalled Forgey's testimony on cross. He states that a person could cut their finger, bleed on the ground, the blood begin to decomp outside the body...dogs would hit on that. Aha! After ICA borrows the shovel to bag Caylee (in the trunk of the car), she goes into the backyard to wash the shovel. Where does she do this? Where cadaver dogs hit.
That's the most reasonable theory I can come up with at this point, but I think it makes sense.
ETA: More to the point, I think this is exactly the scenario the state is trying to show with all this evidence. Big lightbulb moment for me.
