"Based on the location of the shooter and the position of the weapon, it did not activate the system," a district official told the USA TODAY Network.

An AI gun detection system installed in a Nashville, Tennessee high school couldn’t spot the gun a 17-year-old used to fatally shoot another student and himself earlier this week, according to district officials.

The weapon detection system at Antioch High School failed to detect the gun involved in Wednesday’s shooting that left two students dead and two injured. Omnilert, the AI-powered system, ties into the school’s existing camera network to detect weapons on school grounds.
