He went up the escalator to the third floor shooting and wounding three students in the corridor. After entering a classroom where a presentation was being held, he shot at the front row and killed two women who were trying to escape. He shot three more female students and killed another.

He then took off his hat, wrapped his jacket around the gun, said "ah shit," and then killed himself.
