At least 15 other people were wounded in the shootings, which took place over 21/2 hours at Virginia Polytechnic Institute and State University. Some of them were injured as they leapt to safety from the windows of their classrooms.
The shootings, which came just four days before the eighth anniversary of the Columbine High School bloodbath, in which two students killed 13 people and themselves near Littleton, Colo., created panic and confusion at the university, which was already on edge after two weeks of bomb threats.
