The tell tale heart sticker "beating" during court.
I keep thinking there is a reason the hyoid bone was never found. Every time I look at the felon's (CA's) hands I am certain that she used those hands to kill Caylee.
The hyoid bone was, IIRC, the only part of the upper spine and skull area that was missing. If it was found it quite possibly would have proven strangulation. It hit me the most when I saw the defendant lose her temper at LDB and when JB turned around she tried to compose herself and then her hand went to her neck in a bizarre motion that mimicked choking. Then there was the cover of her own mouth and nose with her hands when COD was being discussed.
