Nashville school shooting updates: 3 kids, 3 adults killed; female suspect dead

Three children and three staff members were shot and killed at a private school in Nashville, Tennessee, according to officials.

The shooting unfolded Monday morning at the Covenant School, a Christian school for students in preschool through sixth grade.

The suspect, a 28-year-old Nashville woman, was shot and killed by authorities in a lobby area on the second floor of the school, according to police.

No one who was shot survived, officials said.

The suspect was armed with at least two assault-type rifles and a handgun, officials said.

Authorities said she entered the school through a side entrance and made her way from the first floor to the second floor, firing multiple shots.

Alex Apple told ABC News Live that his mother works at the school’s front desk. Apple said she was at her car when she got an alert saying to shelter in place.

“She got out of her car, heard the gunshots, so she fled,” he said.

The school has about 209 students and about 40 to 50 staff members, officials said.

First lady Jill Biden briefly addressed the shooting at the top of her remarks at the National League of Cities conference on Monday.

“I am truly without words. Our children deserve better,” she said.

Tennessee Gov. Bill Lee tweeted that he’s “closely monitoring the tragic situation.”

“Please join us in praying for the school, congregation & Nashville community,” Lee said.
