I don’t understand why the police don’t report more of what they know around this, given that the one suspect is dead.

Maybe the police had a report of the altercation and they didn't follow up on it.
Just one of many possibilities.

Good point. Maybe the boy initially went to the school to see the school psychiatrist, referred by his mom and/or his doctor?
