Emergency vehicles cluster on Mary Alexander Road on the campus of University of North Carolina at Charlotte after a shooting Tuesday, April 30, 2019, in Charlotte, N.C. The shooting on the campus left at least a few people dead and several wounded Tuesday, prompting a lockdown and chaotic scene in the state’s largest city.

Officers who had gathered ahead of a campus concert raced over and disarmed the suspect. The shooting prompted a lockdown at the University of North Carolina-Charlotte and caused widespread panic across campus as students scrambled to take shelter. “Just loud bangs. A couple loud bangs and then we just saw everyone run out of the building, like nervous, like a scared run like they were looking behind,” said Antonio Rodriguez, 24, who was visiting campus for his friend’s art show.

He said officers assembling nearby for a concert rushed to the scene and arrested the gunman in the room where the shooting took place. Authorities did not immediately release the suspect’s identity. “Our officers’ actions definitely saved lives,” Baker said at a news conference. He said two people were killed, and three remained in critical condition late Tuesday. He said a fourth person’s injuries were less serious. Students were among the victims, but officials would not say how many. Monifa Drayton, an adjunct professor, was walking onto campus when she heard the shots. She said she directed students fleeing the scene to take cover inside a parking deck. “I heard one final gunshot and I saw all the children running toward me,” she said. “We started to get all the children pulled into the second floor of the parking deck and the rationale was if we’re in the parking deck and there’s a shooter and we don’t know where he is, he won’t have a clear shot.” She added: “My thought was, I’ve lived my life, I’ve had a really good life, so, these students deserve the same. And so, whatever I could do to help any child to safety, that’s what I was going to do.” Shortly after UNC Charlotte issued a campus lockdown, aerial shots from local television news outlets showed police officers running toward a building, while another view showed students running on a campus sidewalk. The Charlotte-Mecklenburg Police Department later said that the campus had been secured and that officers were going through buildings to let people who were hiding know that it was safe to come out. In a tweet, Gov. Roy Cooper praised the officers’ quick response. “This is a tragic day for Charlotte and this great university,” he said. “We mourn the lives lost and we will all be here to support each other.” The university has more than 26,500 students and 3,000 faculty and staff. The campus is northeast of the city center and is surrounded by residential areas. Spenser Gray, a junior, said she was watching another student’s presentation in a nearby campus building when the alert about the shooting popped up on everyone’s computer screens. She said she panicked: “We had no idea where he was … so we were just expecting them at any moment coming into the classroom.” Susan Harden, an UNCC professor and Mecklenburg County Commissioner, was at home when she heard of the shooting. She went to a staging area, she said, to provide support. Harden said she has taught inside the Kennedy building, where the shootings occurred. “It breaks my heart. We’re torn up about what’s happened,” Harden said. “Students should be able to learn in peace and in safety and professors ought to be able to do their jobs in safety.”
