I think the “woman” who was being pummeled is the sister of the attacker. There are several articles about this.
I don’t know why they don’t just say he attacked his sister, maybe his Mama too. Indications are that he is severely autistic.
I thought he may have a mental issue. Looking at a vacation picture of him, his sister and father that is posted at the source looks very different from the booking photo.
they should have left him home with a caretaker if he’s so” autistic” that he can’t be out among the rest of us.
