My question involves injury or loss that occurred in the state of: Washington
My younger brother (15) was sitting on my parents porch at 10 pm on a sat night texting in a nicer neighborhood in Washington. Their 50-60 male neighbor came over to the porch, who my brother thinks had been drinking, began to say all sorts of nonsense including phrases such as... "You're a pussy, you're dad's a pussy, you're both fags, stand up and fight me, you should fight my son, I'm going to punch you" (my brother is only 15 and doesn't much of anything back to him) and proceeds to punch my brother in the jaw, grabs his sweatshirt pulls it over his head, ripping his sweatshirt pushes him down into the bushes and then tells him to get up, and punches him again in the side of the head. At this point my mom comes out because of the noise and makes eye contact with the man and he runs to his house. Police were called and the report was filed, apparently they couldn't do anything since he wouldn't come out of his house. Seems a bit ridiculous. Anyway, what are the steps to take now? Possible outcomes? At this point my mother is pretty scared of what else this man is going to attempt to do.
