All students and staff were dismissed from North Quincy High School today at around 10:30 am as a precautionary measure after an expended micro-smoke device was found in the Media Center. The device was not expended in school. After the building was evacuated, Quincy Police Department K-9 units and Quincy Public Schools administrators performed an exhaustive sweep of the building. This sweep uncovered no more devices and the building is safe to reopen on the regular schedule for Tuesday, December 11. Please note that this is a previously scheduled early release day for students, with dismissal at 12:35 pm.
