A female shooter wielding two “assault-style” rifles and a pistol killed three students and three adults at a private Christian school in Nashville on Monday, authorities said. The suspect also died after being shot by police.

The violence occurred at The Covenant School, a Presbyterian school for about 200 students from preschool through sixth grade.

The killings come as communities around the nation are reeling from a spate of school violence, including the massacre at an elementary school in Uvalde, Texas, last year; a first grader who shot his teacher in Virginia; and a shooting last week in Denver that wounded two administrators.

Police said the shooter appeared to be in her teens.

The Nashville victims were pronounced dead upon arrival at the Monroe Carell Jr. Children’s Hospital and Vanderbilt University Medical Center.

Other students walked to safety Monday, holding hands as they left their school surrounded by police cars, to a nearby church to be reunited with their parents.

Police officers with rifles, heavy vests and helmets could be seen walking through the school parking lot and around the grassy perimeter of the building Monday morning. Helicopter footage from WTVF also showed the officers looking around a wooded area between the campus and a nearby road.

Jozen Reodica heard the police sirens and fire trucks blaring from outside her office building nearby. As her building was placed under lockdown, she took out her phone and recorded the chaos.

“I thought I would just see this on TV,” she said. “And right now, it’s real.”

On WTVF TV, reporter Hannah McDonald said that her mother-in-law works at the front desk at The Covenant School. The woman had stepped outside for a break Monday morning and was coming back when she heard gunshots, McDonald said during a live broadcast. The reporter said she has not been able to speak with her mother-in-law but said her husband had.

“In a tragic morning, Nashville joined the dreaded, long list of communities to experience a school shooting,” Nashville Mayor John Cooper tweeted, thanking first responders and medical professionals. “My heart goes out to the families of the victims. Our entire city stands with you.”
