He could have done that in her room, in the basement, before or after the garotte was in place... I think he looked in her face and did that - - and there is a movie that brings to mind - - the bad guy was with a woman, hurting her. He had his hands on her head and said he could smash her skull with his bare hands.

I can't remember what movie it was - - was it released before the murder?

The marks should not be ignored - - they are an injury she got that night. I have no problem attributing that act to an intruder. I can't imagine a parent doing that.
