At around 2:52 p.m., Weise returned to the main entrance, where he killed two students and wounded two others. The police had arrived quickly and engaged him in gunfire. FBI special agent Paul McCabe said the shootout lasted for about four minutes. None of the police officers were injured. After being hit three times in the lower back, right leg, and right arm by police gunfire, Weise retreated to a vacant classroom. He leaned against a wall, put the shotgun barrel to his chin, and fired, killing himself.
