Tidarrius M. Smith, 31, was fatally shot in Chicago on November 2, 2016. His killing occurred during a year when the city saw a major spike in homicides, a wave of violence that affected many South and West side neighborhoods and was driven in part by gang conflicts and concentrated gun violence.

Commentary about 2016 links the rise in shootings to multiple factors, including reductions in stop-and-frisk operations after ACLU pressure and a consent decree, a shift some analyses say reduced deterrence of illegal firearm possession. Over two-thirds of that year’s homicides were estimated to be gang-related, complicating prevention and investigations.

Smith’s death is part of that larger pattern of loss in Chicago that year. If anyone knew Tidarrius, saw him that day, or has information about the shooting, please come forward to local authorities.
