On the afternoon of January 5, 2012, 19-year-old Darryl Nicholas McCoy Jr., a resident of Suitland, Maryland, was found in a District Heights parking lot after being fatally shot. Local investigators initially had no suspect or clear motive as the case opened in the new year.

The investigation developed over the following weeks. In March 2012 authorities arrested 27-year-old Jonathan Blades of Gaithersburg in Temple Hills and charged him with first-degree murder in McCoy’s killing. Blades was later indicted, tried, and a jury found him guilty of first-degree murder; he was sentenced for his role in the death.

What details about the shooting or the people involved might help explain why McCoy was targeted?
