Metro Nashville Police are investigating social media posts possibly made by the 17-year-old student who opened fire at Antioch High School.

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

Metro Nashville Police Department authorities have provided updated information on Thursday after a shooting in the Antioch High School cafeteria the day prior.

The position of the camera and the shooter led to an AI-powered weapon detection system failing to pick up on a student's gun.

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

Two students are dead and another student was injured after a shooting inside Antioch High School on Wednesday.

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.

One student is dead and another is wounded after a third student opened fire with a pistol Wednesday at Antioch High School in Nashville, Tennessee, police said. The 17-year-old shooter then shot himself and died, according to police.

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

Authorities are examining “very concerning online writings and social media posts” connected to the shooter who killed a female student and wounded another student in a Nashville high school cafeteria.

Mayor Freddie O'Connell on Thursday announced a new Community Foundation of Middle Tennessee fund for victims in the Antioch High shooting.
