Gary Clark, 39, was fatally shot in Chicago on October 9, 2012. His death came during a year that saw a sharp rise in homicides citywide, with more than 500 killings in 2012 and particularly heavy impacts on neighborhoods of the South and West sides.

Reporting ties the 2012 surge to a mix of factors mentioned at the time: socio-economic disparities, gang activity, changes in policing strategy including the disbanding of specialized gang units, and an unusually warm spring that some experts suggested may have heightened tensions. Clark’s killing is described as part of that broader wave of violence affecting communities with limited resources.
