MOO looks like a split jamb from shouldering in a door.And she wasn't facing him grabbing his bicep because that would be most likely a thumb in that position of his arm in a grab. Only thing that would fit would be reach out and slashing at him while facing him or grabbing him from behind would put fingernails there.... but two short scratches and not all three middle fingers? but I don't know...I guess I need to hear the theory before I commit to fingernail scratches made by Suzanne. But then everyone knows by know I'm super cautious about jumping to conclusions LOL. Same with the jamb ...need to ask my husband about that one and show him the image. We've had plenty of tenants push in doors in rentals when they lost their keys instead of calling and it really splinters the wood and does more damage than making a vertical crack so need to know more about that one too since maybe interior doors are more flimsy so you could pressure it open without more damage. I just don't have enough knowledge to come to a conclusion about the "how" let alone the "when".
It's a big split.
