Fifteen-year-old Jacquez H. Mack was shot and killed on June 7, 2017, in the Lawndale neighborhood on Chicago’s West Side. Jacquez and another teen, Corey Hill, were standing on a sidewalk when a masked gunman exited a vehicle, opened fire on both youths, then returned to the vehicle and fled. Both victims were taken to Mount Sinai Hospital and were pronounced dead shortly afterward.

The shooting occurred amid a particularly violent day in Chicago, one of several fatal incidents that highlighted the city’s struggle with gun violence and the frequent vulnerability of young people in neighborhoods like Lawndale. As of the time of this report, no arrests had been announced and the investigation remained open.

Does anyone have information about Jacquez, his movements that day, or any details about the vehicle or suspect that could help investigators?
