ATLANTIC CITY — A portion of the 1700 block of McKinley Avenue was closed Monday afternoon while Atlantic City police investigated a shooting. Police responded at about 2:40 p.m. after a ShotSpotter alert and found evidence of gunfire, according to a post on the department’s Facebook page. The Atlantic City Fire Department also responded to the scene. Students and staff at Dr. Martin Luther King Jr. School were placed in shelter-in-place status because of the nearby shooting, according to the post. When asked for more information, Sgt. Kevin Fair declined further comment, and Atlantic City School District Superintendent Barry S. Caldwell was not immediately available. A handful of neighbors gathered at either end of the block while police investigated the area. The article notes that ShotSpotter is an audio-detection system that alerts police when gunfire is detected, even if no one calls 911. No information about victims, suspects, injuries, or arrests was provided in the available report.
