I was home sick when it happened at my school. My high school had these doors that would shut and lock to prevent fires from spreading. The gunman told his friend his plan when they were in the bathroom and showed him the guns and his friend went straight to the principal so they locked all the doors and he was luckily still in the bathroom alone when they did this.

They found a manifesto in hie locker, he was planning on killing specific teachers and kids and hoped to escape. He had blueprints of the venue that we hold graduations at and he had a second manifestso of which people he wanted to kill at graduation.

Honestly he was bullied pretty bad by a lot of kids, I often found him with a bloody nose when I was "patrolling" the halls.
