On the afternoon of Friday, September 12, 2014, 26-year-old Shandon Barnes Jr., known to family as Big Man, was driving a blue Chevrolet Trailblazer on Flanders Street in the Algiers neighborhood of New Orleans around 4 p.m. A 4-door silver car pulled up and someone inside opened fire. Barnes was struck multiple times, including a fatal head wound; his Trailblazer left the road and crashed into the fence of a two-story apartment building near Socrates and Flanders, and he was pronounced dead at the scene.

Investigators treated the killing as possibly retaliatory after learning Barnes had been involved in a confrontation a couple of months earlier. Two months after the shooting, police publicly sought a man named Wellington Cornin, Sr., then 24, as someone who might have information; Cornin was never charged in Barnes’s murder. About a year later Cornin was arrested and later pleaded guilty to manslaughter in an unrelated killing, but Barnes’s homicide remains unsolved and open.

If anyone knew Shandon, saw activity in the Socrates and Flanders area that afternoon, or has information that could help, please come forward.
