NASHVILLE, Tenn. (WSMV) - Update: WSMV4 Investigates has confirmed with the Metro Nashville Police Department that two guns were removed from the home of Antioch High School shooter Solomon Henderson in 2023. An MNPD spokesman confirms that the two guns belonged to adults and have remained in the department’s property room since then.

The suspected shooter who killed one student at a high school in Nashville on Tuesday has been identified as Solomon Henderson, 17.

Analysts with the ADL Center on Extremism "have located a manifesto and social media accounts believed to belong to the shooter, where he shared a range of incel, accelerationist, white supremacist, antisemitic & anti-Black content," the organization wrote in a Wednesday post on X (formerly Twitter ).

Police responded to a shooting at Antioch High School in Nashville, Tennessee. Police told CBS News the shooting happened in the school cafeteria.

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.

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.

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.

According to MNPS Spokesperson Sean Braisted, metal detectors are not standard at traditional or magnet schools in the district. The only instance they are used is at Alternative Learning Centers, which are for students who have been expelled from school.

One of the 12-year-olds threatened to shoot four of his classmates, the other posted a threat on Instagram and an 11th grader threatened “Antioch part two,” according to police.

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