Could be. I proposed that it wasn't the first time KC could have used Chloroform to put Caylee to sleep in the car.
Do you suppose the heart signifies some "ritual" protection?
I really don't think so. I think it would be more like
Okay Caylee, mommy has a big date, so into the bag you go. You know I have to place tape over your mouth so you don't make any noise. Breath deep now honey and mommy will leave a pretty sticker for you for being such a big girl.
Wow....that was sick and twisted. Sadly, I can see this happening...if it was an accidental (cough cough) overdose of chloro, which I doubt very seriously.
Even if the above....using the chloroform, knowing that it is a dangerous and deadly substance, on a young child is not an accident. Placing a living, breathing child in a laundry bag and duct taping their mouth shut and having that child die, is child abuse and murder, even if you didn't plan for it to happen.
The defense better hope that there are no finger prints, hairs, DNA, etc, in the bag, at the scene, on the body, wrapped in the tape, that can place KC there because sticking with the invisi-nanny story, even if it can all be proven a lie, looks better for them than trying to go with the accidental death scenario with what the prosecution has at this point.
