Another day in America means, unfortunately, another school shooting. A shooting on a North Carolina university campus left two people dead and four wounded Tuesday, prompting a lockdown and chaotic scene in the state’s largest city. UNC Charlotte issued a campus lockdown late Tuesday afternoon, saying shots had been fired.

“Shots reported near Kennedy. Run, Hide, Fight. Secure yourself immediately,” the university said in an alert, referring to the school’s Kennedy building on campus.

Officials said five shots were fired at around 5:45 p.m. local time near UNCC’s Kennedy Building. Allison Latos of WSOCTV reports police has one suspect—a 22-year-old male student—in custody. The Charlotte-Mecklenburg Police Department later said that the campus had been secured and that officers were going through buildings to let people who had sheltered in place know that it was safe. Police said that one suspect was in custody, and it didn’t appear that others were involved.

“We are in shock to learn of an active shooter situation on the campus of UNC Charlotte. My thoughts are with the families of those who lost their lives, those injured, the entire UNCC community and the courageous first responders who sprang into action to help others,” Charlotte Mayor Vi Lyles said on Twitter.

Susan Harden, a professor of education on campus since 2011 who also serves on the Mecklenburg County Board of Commissioners, expressed disbelief at the gun violence.

“This is a day at the end of the semester, when students are doing performances, presentations … this is just the worst thing,” said Harden said at the police staging area. “Our campus is so safe. So safe. I’ve never felt unsafe on our campus. I’m heartbroken.”

She added, “I’ve got a student who’s barricaded in her dorm right now.”

The campus was to host a concert at the school’s football stadium. The university has more than 26,500 students and 3,000 faculty and staff. Tuesday was the last day of classes, with exams to begin on Thursday.

Stay tuned, as this story is still developing.
