On June 7, 2017, 15-year-old Jacques Mack and his 16-year-old friend Corey Hill Jr. were fatally shot on the West Side of Chicago in the North Lawndale neighborhood. The teens were standing on the sidewalk in the 1200 block of South Lawndale at about 9:06 a.m. when a masked suspect armed with a rifle exited a silver vehicle and opened fire. Both boys were struck multiple times, taken to Mount Sinai Hospital, and pronounced dead.

Witnesses said the gunman stood over the victims and continued firing as they lay on the ground. Jacques, who lived in East Garfield Park, and Corey, known to friends as Montana Garcia, were described as best friends. The motive was not immediately clear, and no arrests were announced in the immediate aftermath; the investigation faced significant challenges and remained unsolved for some time.

Anyone who knew Jacques or Corey, or who has information about the shooting, is asked to come forward to help bring answers to the families.
