On the morning of August 6, 2015, a red Pontiac Grand Am was found in a ditch off Parks Drive in Powder Springs, Georgia. Inside the car, 22-year-old Catherine Costner and her 24-year-old husband, Anthony Costner, had been shot. Anthony was pronounced dead at the scene; Catherine was taken to a hospital and later died of her injuries. Their 3-year-old daughter was in the vehicle and was not physically harmed.

Investigators say the Costners had arranged to meet with people that night after receiving a call to help someone, and police have characterized the event as connected to a drug transaction rather than a random act. Within days authorities arrested three suspects: 39-year-old Roy Hicks, alleged to be the gunman and charged with murder, aggravated assault, possession of a firearm by a felon, and cruelty to a child; 22-year-old Demarco Thomas, charged with conspiracy to violate the Georgia Controlled Substances Act, concealing a death, and hindering apprehension of a felon; and Raymond Ladell Webb, accused of arranging the meeting and of concealing a death, hindering apprehension, and a felony drug charge.

Does anyone have information about the call the Costners received that night or about movements on Parks Drive leading up to the discovery?
