My 16 year old son got into an argument with my 25 year old daughter and he ended up shoving her into a wall causing her a concussion from the shove. Her husband heard them arguing, tried to break up the fight, and ended up fighting with my son. My son in law now has a black eye and my daughter wants to file a report with the police against my son for injuring her, as he has been aggressive with her before. We all live in the same home & he is defiant, but he has never been in trouble with the police before. Can he be charged as an adult for assaulting my daughter? What might the consequences be if she decides to go through with the report? Can this be adressed without involving the police?
