Of course he needs to be institutionalised, but I bet to fuck that this didn’t just happened out of thin air and parents were neglecting symptoms. I bet they didn’t want to / couldn’t deal with it because of the insane (no pun) costs associated with it. (only in the USA, of course)
Either way, shooting down an underage with a sharp stick is barbaric and medieval.
