The shooter was outside in the hallway. A small group of men and women were in a classroom. After hearing an urgent voice over the walkie-talkie explaining where the shooter was, the men and women took chairs and bookshelves to barricade the door, then stood back against the wall to wait.

Suddenly, there was a pounding on the door as the shooter tried shoving his way in. He pushed against the door and the barricade, but what seemed like an eternity only lasted about a minute and he gave up and continued on.

He shot five people, killing two. Soon after, the shooter committed suicide.
