This is the saddest day in UNC Charlotte’s history. Earlier this evening, the unthinkable happened on our campus. At approximately 5:40 PM, an individual opened fire in a UNC Charlotte classroom, cutting short the lives of two members of our community and seriously injuring four others.

Families of the deceased victims are being notified, and university staff are with those who are injured. The entire UNC Charlotte community shares the shock and grief of this senseless, devastating act. This was an attack on all of Niner Nation.

I am proud of and grateful for the efforts of UNC Charlotte Police and Public Safety, the Charlotte-Mecklenburg Police Department, and other emergency officials. The suspected shooter is in custody and lives were saved thanks to their rapid response. Their work on campus will continue over the next several hours. Students and staff on campus should follow the instructions of law enforcement officials and the instructions issued in NinerAlerts. Everyone else should remain off campus until an all-clear message is issued.

The days ahead will be some of the most challenging we have ever encountered. All I can say for certain is that we will get through them together.
