Gregory Miller was 18 when his body was found in the driveway of North High School in Springfield, Ohio, on June 21, 1980. Investigators say he was the apparent victim of a hit-and-run that occurred in the early morning hours; the coroner estimated his time of death at about 3:30 a.m., and authorities discovered his body around 6:30 a.m.

Several people were interviewed after the crash, and investigators believe as many as four witnesses may have been inside the vehicle that struck Gregory. No arrests have been made, and the Springfield Police Department classifies the case as an unsolved homicide. The Ohio Attorney General’s Office lists the case among its cold cases.

Gregory was active in sports at North High School and had hopes for the future. Anyone with information about that night is urged to contact authorities; even a small tip could help bring answers for his family and friends.
