On Thursday, Wilmington’s Freeman Elementary and Mosley Performance Learning Center were both locked from the outside for several hours following a shooting at the nearby Creekwood housing community. The next day, a gunfire incident behind the College Road K-Mart led to the brief lock-down of Isaac Bear Early College. A lock-down means access to and from the schools is restricted, and classrooms lock their doors, turn off the lights and shut the blinds. New Hanover County Schools go into this heightened security mode whenever police activity occurs in the vicinity of a school.
