The teenager who survived the January 2025 shooting at a Nashville, Tennessee, high school recently has sued the manufacturer of an “AI gun detection” system that failed to detect the handgun that left two dead, including the shooter. The shooting occurred at Antioch High School's cafeteria and left two people dead, including a 16-year-old girl and the 17-year-old gunman. The shooter fired 10 shots within 17 seconds inside the cafeteria, fatally shooting the teenager before taking his own life, CNN reported. Following the incident, police stated that a 17-year-old student suffered a graze wound to the arm and was treated before being released. Another male student sustained an injury to his face but was not struck by gunfire.The lawsuit, filed in Davidson County court in May 2026, states that the security company Omnilert either knew or should have known that there were “significant operational limitations in its gun detection system that could result in detection failures during actual emergencies, including limitations based on camera placement, proximity of the weapon to camera sensors, camera angle, lighting, and weapon visibility.”At the time of filing this report, Omnilert cofounder Ara Bagdasarian had not responded to the lawsuit. System Integrations, the other defendant in the case and the company that resold the Omnilert system, also declined to comment.In 2023, the Metropolitan Nashville Public Schools (MNPS) Board approved a contract valued at more than $1 million to add Omnilert's gun-detection software, an AI-powered detection layer, to the district's existing network of security cameras and related infrastructure. The agreement, awarded to Omnilert and reseller System Integrations, took effect on March 23, 2023, and ran through November 30, 2025.According to the proposal, the contract's total value did not exceed $1,050,487.80, with the cost distributed over two years. In a press conference after the January 2025 shooting, MNPS spokesperson Sean Braisted said that due to where the shooter was in relation to the cameras, the imagery “wasn’t close enough to get an accurate read and to activate that alarm,” as quoted by NBC News.The lawsuit repeatedly references marketing materials from Omnilert’s website, including content archived by the Internet Archive just days before the shooting, and alleges that the company oversold the capabilities of its technology, according to Ars Technica.ALSO READ: Georgia Crime: Couple found dead in apparent murder-suicide as children remained inside home, son's 911 call revealed what happened next
