Robert Vaughn, a 29-year-old African-American man, was found fatally shot in a New Orleans neighborhood on March 7, 2015. Local authorities opened an immediate homicide investigation after his discovery.

Detectives say the probe stalled quickly: evidence from the scene was limited and witnesses did not come forward, leaving no suspects identified and no arrests. The case remains unsolved and is listed among other cold homicide investigations in the city.

Anyone who knew Robert, was in the area that night, or has information that could help investigators is urged to come forward.
