Robert L. Snipes, 31, was shot and killed on July 4, 2012, in Chicago. The killing occurred amid a year when the city saw a steep rise in homicides, driven in large part by gang-related violence concentrated on the South and West Sides. The neighborhood where Snipes was slain was experiencing frequent gang incidents and territorial and narcotics conflicts that contributed to the broader wave of gun homicides that year. His death is one of hundreds in 2012 that illustrated how local gang faction activity and street shootings put residents at risk.

Does anyone who knew Robert Snipes or who was in that neighborhood around July 4, 2012, have information that could help clarify what happened?
