I haven’t seen any articles that say she was hit in the eye, only hit in the back of the head and kicked. I don’t think that is a black eye from a punch. Wouldn’t it be swolen and the eye red? I’m not saying the story is fabricated, just that I think the blackness around the eye is from makeup and crying, plus, like I said, I’ve seen no reports saying she was hit in the eye/face.
A very nice but quite persistent MD, in an interview room with an very experienced detective, is going to find the truth. It can't be hidden. The truth is written on her face, to the experts who know how to analyze injuries.
