I've heard the same as you, mystery. Do we possibly have "dueling experts" here? And I don't mean on TV, but in official proceedings. I mean there was a Grand Jury that heard the evidence and they did not indict anyone.
I've heard several times that the head wound was after she was strangled...her heart had stopped...there was no blood or swelling and they didn't even notice it until the autopsy....I am more confused than ever.
