Police released pictures of a black car they are looking for in connection with the death of 15-year-old Violet Harris, who was killed in a hit-and-run while riding on a scooter last month in the South Shore neighborhood. The car is a dark colored Ford Fusion, according to Cook County Crime Stoppers, which is also offering a cash reward of up to $1,000 for information that leads to the arrest of the individual responsible for the deadly crash.
