The Northern Illinois University shooting was a school shooting that took place on February 14, 2008, during which a gunman shot multiple people on the campus of Northern Illinois University in DeKalb, Illinois, United States, killing six and wounding eighteen.
The incident happened on the campus's Cole Hall at approximately 3:05 p.m. local time. The school placed the campus on lockdown; students and teachers were advised to head to a secure location, take cover, and avoid the scene and all buildings in the vicinity of the area. Six people died in the incident, including the perpetrator, making it the fourth-deadliest university shooting in United States history, after the Virginia Tech massacre, the University of Texas Clock Tower shooting, and the California State University, Fullerton library massacre.
