Law enforcement officials seeking a motive for a shooting at Nashville’s Antioch High School on Wednesday morning are examining alarming social media posts and writings tied to a teenager police say shot and killed a 16-year-old girl.

Nashville police and schools are monitoring social media discussion and concerns Thursday as people speculate if additional schools could be targeted after a 17-year-old student opened fire Wednesday at Antioch High School, killing himself and a 16-year-old girl while injuring another, officials said.

A student shot at least two other students Wednesday at Antioch High School outside Nashville, Tennessee, police said. The shooter then shot himself, according to police.

The tragic shooting at Antioch High School has sparked concerns over the effectiveness of its AI-based weapons detection system, Omnilert.

NASHVILLE, Tenn. (AP) — A shooting in a Nashville high school cafeteria Wednesday left a female student dead and another student wounded, nearly two years after another deadly school shooting in the city that ignited an emotional debate about gun control in Tennessee.

Superintendent for Metro Nashville Public Schools Adrienne Battle said the school uses a weapons detection system called Omnilert.

A 17-year-old boy armed with a pistol, identified by authorities as Solomon Henderson, fired several shots in the cafeteria. A female student, 16-year-old Josselin Corea Escalante, was killed and a boy was grazed on his arm. Henderson then shot himself in the head and was fatally wounded.

Gunfire erupted just after 11 a.m. Wednesday at Antioch High School – about 45 minutes southeast of downtown Nashville – when 17-year-old Solomon Henderson “confronted” the victim before firing

Multiple threatening messages began circulating online after a 17-year-old student walked into Antioch High School’s cafeteria and shot two fellow students, killing one of them, on Wednesday. The latest was an online post threatening to shoot up six Nashville-area middle schools.

At his weekly media roundtable Friday, Mayor Freddie O'Connell denounced additional threats of violence in the wake of the Antioch High shooting.
