On January 4, 2015, 20-year-old Dwight DJ Grayer was shot while sitting in his car at a traffic light at North Duke Street and Horton Road in Durham, North Carolina. A gray car pulled up beside his vehicle and someone inside opened fire. Grayer was taken to the hospital with serious injuries and succumbed to those wounds months later in September, after which police reclassified the case as a homicide.

Durham police continue to investigate and are offering a reward for information that leads to an arrest. The shooting was one of several that fed a surge in gun violence in Durham during 2015, a year when homicides nearly doubled. Few details about the shooter or motive have been released.

If anyone has information about that January 4 shooting or about Dwight Grayer’s movements that day, can you share what you know with investigators?
