Frederick D. Williams, 21, was fatally shot in Chicago on August 22, 2012. His killing occurred during a year when the city saw a significant rise in homicides and a large number of gun-related incidents, many concentrated in economically disadvantaged neighborhoods.

Frederick’s death is presented as part of that wider struggle to reduce violent crime amid persistent underlying social problems.
