A Dubuque man was arrested with what turned out to be an empty handgun while he was inside a Dubuque elementary school. Tuesday Authorities say 39-year-old John McGee had arrived several minutes after classes were dismissed and was allowed into the building by a staff member. The resource officer observed a bulge in McGee’s shirt just above his waistline and recognized the shape to be consistent with a handgun. The officer disarmed McGee without incident and he was placed under arrest.
