Mercedes Contreras was 18 when she was shot in the early hours of July 7, 2022, on the 100 block of Shellbark Way in Savannah, Georgia. Officers responded to a call about 12:30 a.m. and found her with gunshot wounds; she was taken to Memorial Medical Center and died that evening.

Investigators concluded the shooting was not random and interviewed persons of interest who were at the scene. Within days the probe produced an arrest: on July 18, 2022, 22-year-old Kavon Giles was taken into custody and booked into the Chatham County jail on charges of involuntary manslaughter and pointing a gun at another.

Who knew Mercedes or was in that neighborhood that morning and can help fill in the timeline?
