Calvin Bernard Harvey was 16 when he was killed at a cookout on Edgewood Drive in South Macon, Georgia, in the early hours of June 17, 2018. Known to friends as Chop and a rising junior at Northeast High School, he had been raised by his grandmother among several grandchildren. Shortly after 12:30 a.m., a vehicle drove past the gathering and opened fire into the crowd.

Calvin was found on a stoop with a gunshot wound and was pronounced dead at the scene. Three other people—a 13-year-old girl, a 23-year-old man and a 25-year-old woman—suffered minor injuries before the vehicle and its occupants fled. Two months later, on August 17, 2018, investigators arrested 15-year-old Sharmarian Bobby Chatfield and booked him on a murder charge in connection with the shooting.

Does anyone who attended that cookout or who was in the neighborhood that night have information that could help explain what led to this drive-by attack?
