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.

WSMV4 Investigates learned that police were not notified by the Omnilert system as it failed to detect the weapon used in the cafeteria.

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.

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