A faculty member at the University of North Carolina at Chapel Hill was shot and killed in a campus building Monday afternoon, officials said in a press conference.

Shortly after 1 p.m. ET, UNC Police were notified of shots fired at Caudill Laboratories, a chemistry building near the center of campus. UNC Police arrived at the scene and found one faculty member shot. No one else was injured, UNC Chief of Police Brian James said.

The faculty member has not been identified pending notification to their family. The motive of the shooting is still unknown.

“This is truly a tragic case for our campus community,” UNC Chancellor Kevin Guskiewicz said. “This is really a time for the community to come together. These tragic events sadly are happening across our nation.”

Classes at UNC Chapel Hills were canceled for the rest of Monday and on Tuesday. The University has also sent resources to students, faculty and staff, Guskiewicz said.

“I’m sorry so many of you are feeling uncertain about your safety right now . . . We’re here for you. I’m pleading with you to use any of the resources that you many need and we’ll come together as a community to ensure your safety,” Guskiewicz said to a group of students who attended the press conference.

A suspect was identified and brought into custody at 2:31 p.m. ET, but their identity will not be released pending formal charges, James said. UNC Police underwent a verification process of the suspect before lifting the campus lockdown at 4 p.m. because “we wanted to be sure we had that person in custody and it was the correct person.”

“It’s a day we trained for, but we hope never comes,” James said. “We are committed to conducting a thorough investigation.”
