A gun was found at two Florida and Maryland high schools on Dec. 5, 2025, leading to student arrests and lockdowns.

A gun was discovered at Northwood High School in Rockville, Maryland, during a fight between two students on December 5, 2025, prompting a lockdown. Authorities found a loaded, 3D-printed firearm without a serial number on 17-year-old Isaiah Gaunt, who was arrested and charged as an adult with multiple firearm offenses. At East Ridge High School in Clermont, Florida, a separate lockdown occurred after a staff tip led to the discovery of a firearm in a metal lockbox. Two students were taken into custody and face charges related to firearm possession on school grounds. No injuries were reported at either school, and both campuses remained under lockdown while authorities conducted safety sweeps.
