During morning arrival, the Evolv weapons detection system alerted staff to a weapon in a student’s backpack. The system is an AI-powered security screening technology that quickly scans individuals for concealed weapons using sensors and machine learning, allowing for high-throughput, non-intrusive threat detection.

A loaded handgun was found in a student's locker at North College Hill High School, prompting a lockdown of both the high school and middle school, police said.
