A routine custody exchange at an Exxon on Courthouse Road in Stafford, Virginia, ended in homicide on the evening of May 20, 2016. Twenty-year-old Austen Tyler Agnor of Chester, Maryland — a husband, father and U.S. Army serviceman — drove with his wife to drop off his wife’s two-year-old daughter for a weekend visit with her biological father. The meeting was scheduled for 7:15 p.m.

An argument erupted between Agnor and the child’s father, 27-year-old Corey Andrew Terry of Richmond. During that dispute, with the child and her mother nearby, Terry shot Agnor multiple times. Agnor was taken to Stafford Hospital Center and was pronounced dead. Deputies arrested Terry about 9 p.m. roughly five miles from the scene; he was charged with first-degree murder and felony use of a firearm and held without bond.

Who was in the area that evening and might have seen the exchange or the vehicle movements leading up to the shooting?
