Two off-duty police officers who were visiting the school were alerted to the shooting, but were at different ends of the school. One of them approached the bathroom and called for backup. More officers quickly arrived and charged the bathroom, where they discovered Williams kneeling on the floor with the weapon in his hands. He wanted to commit suicide, but was unable to do so. He told the officers that he was by himself. In the end, he shot 15 people, two of whom died.
