The Northern Illinois University shooting was a school shooting on February 14, 2008, at Northern Illinois University in DeKalb, Illinois. Steven Kazmierczak opened fire with a shotgun and three pistols in a crowd of students on campus. He killed five students and injuring an additional 17 people, before shooting himself.
The school placed the campus on lockdown; students and teachers were told to go to a safe place, take cover, and avoid the scene and all buildings near the scene of the shootings. Six people died in the incident, including the shooter, tying it with the University of Iowa shooting as the fifth-deadliest university shooting in United States history.
