Marcus E. Smith was 28 when he was fatally shot in Chicago on April 10, 2016. His death occurred during a year that saw a sharp and sustained rise in homicides across the city, with 2016 recording 764 killings overall.

That year’s spike in violence began in January and remained above 2015 levels each month, driven overwhelmingly by gunplay — about 90 percent of Chicago homicides involved firearms in 2016. The surge affected many neighborhoods and coincided with increases in non-fatal shootings and armed robberies, issues linked in reports to illegal firearms and broader socio-economic problems.

Marcus’s killing is one of many that year illustrating how gun violence shaped Chicago’s crime trends in 2016. If anyone knew Marcus or has information about the shooting on April 10, 2016, please come forward with tips.
