During the two attacks, Cho killed five faculty members and twenty-seven students (two students in West Ambler Johnston and thirty people five professors and twenty-five other students at Norris Hall) before he committed suicide. The Virginia Tech Review Panel reported that Cho's gunshots wounded seventeen other students and Professor Grant; six more were injured when they jumped from second-story windows to escape from Professor Librescu’s classroom. Sydney J. Vail, the director of the trauma center at Carilion Roanoke Memorial Hospital, said that Cho's choice of 9 mm hollow-point ammunition increased the severity of the injuries. Twenty-eight of the victims were shot in the head.
