ShotSpotter, the city’s gunshot detection system, quickly picked up a barrage of gunfire that left Chicago Police Officer Aréanah Preston fatally wounded during a shootout with robbers on her way home from work early Saturday.
However, an officer wasn’t dispatched to her block in Avalon Park until her Apple Watch reported a car crash around 2:02 a.m., roughly 20 minutes after the initial ShotSpotter alert. A traffic cop ultimately responded at 2:15 a.m. and reported Preston had been shot.
