A deadly exchange inside a small convenience store ended one young life on the night of November 8, 2017. Jonathan Vilchez, 22, was in the Lucky Corner Market on Georgia Avenue NW in Washington, D.C., when surveillance footage shows a confrontation with 23-year-old Mario Alfaro and two companions. Both men drew handguns; Vilchez fired first and struck Alfaro. As Alfaro and the others fled, Alfaro turned and shot multiple times at Vilchez, who collapsed in the doorway and was pronounced dead from multiple gunshot wounds.

Officers found Alfaro a few blocks away with gunshot wounds to his arm, stomach, and leg. Two handguns believed to be used in the incident were recovered. Police linked the shooting to suspected gang activity and noted a possible connection to another fatal shooting in the area a day earlier. Alfaro was arrested and charged; his attorneys argued self-defense based on Vilchez firing first, but a judge rejected that claim because of Alfaro’s aggressive behavior on video. Alfaro later pleaded guilty to voluntary manslaughter and was sentenced to seven years in prison.

If anyone remembers Vilchez or saw the moments before or after the shooting at the Lucky Corner Market, any additional detail could be important.
