A 16-year-old female student was killed, another student was wounded, and the shooter—a 17-year-old male student—killed himself, per police.

One student was killed and another wounded in a shooting at Antioch High School in Nashville on Wednesday morning. The shooter, identified by police as 17-year-old Solomon Henderson, died by suicide at the scene, authorities said. Henderson was a student at Antioch.

The Antioch High School shooter and Abundant Life Christian School shooter had similar social media activity prior to the attacks.

A 17-year-old boy who opened fire in his Nashville high school's cafeteria fired a total of 10 shots from a 9 mm pistol within 17 seconds of entering the room.

Investigators are looking into the Nashville school shooter's social media and writings. Sources tell CBS News that Nashville gunman Solomon Henderson and Natalie Rupnow — who's accused of opening fire inside a Wisconsin school — appeared to follow each other on social media.

The investigation into why a Nashville high school student fatally shot a classmate before killing himself has centered on his online writings, which authorities describe as concerning warning signs.
