I voted "other".
This is my opinion only.....
Casey placed already dead Caylee in a large garbage bag, wrapped the duct tape around the bag, along with something heavy to weigh the bag down.
As the body decomposed, while in the trunk, the body fluids leaked through a tear or hole made by the heavy object.... and left a stain "the size of a basketball."
After Casey placed/threw her precious baby's body in the woods....
the skin and other soft tissues eventually came away from the body, while submerged in water for several months.
Due to the water, the body gases, and decomposition...
the bag and duct tape became loosened from around the remains and the weighted object.
The skull and other bones came apart from each other (because of the soft tissue no longer there to hold them together and in place).
Then the current, the weather, animals, searchers, or ? ..... dislodged some of the remains from the loosened bag. As the bag was loosening, some of the duct tape came in contact with the skull and adhered itself to it.
As for how Caylee actually died... as I've said before, I think Casey had been thinking of ways to do away with Caylee for a long time. I don't think she saw herself as Caylee's "mother" and resented having to take care of her.
Caylee may have been crying very loudly, asking for Cindy, wanting to go home....
and I think with all the rage brewing inside Casey from the fight she had with Cindy, etc and wanting to be with TL and at Fusion... she, in a fit of anger, hauled off and whacked her, threw her, shook her... thus killing baby Caylee.
(Re the bag and tape loosening from the body.... I had said the same thing about baby Connor, when a few people thought he had been strangulated by Scott. It was the tape that had loosened from around the bag that held Lacey. The gases had pushed Connor from the womb, and the tape became tangled around his neck.)
Sorry to be so graphic. It hurt like heck to write the above descriptions.
