Shooting at a local school

I just read that it is at least 18 kids as well.. but then in the actual article they say 'undisclosed number of children'... this is insane! They're also reporting that the gunman was the father of one of the students there.. and that the principle and school psychologist are among the dead.. the world becomes a crazier and more unpleasant place every day.. i am just sick over this
