GARDNER — On Friday, Nov. 6, 2026, at about 7:30 p.m., Gardner police responded to 53 Waterford Street following a report that a man was making violent threats and might be armed.
According to Gardner Police Sergeant Ryan Coates, when officers arrived on scene, they found David Margeson, 42, locked inside his apartment.
