Lydell D. Wilson, a 32-year-old resident of Chicago, was killed on October 19, 2017. His homicide occurred during a year of intense violence in the city, when Chicago recorded 624 gunshot-related deaths that made up 92.4 percent of all homicides in 2017. That year also saw nearly 3,000 shootings and over 2,600 men and more than 300 women wounded by gunfire.

Wilson’s death is one of many that disproportionately affected male victims and Black or Hispanic communities. Fewer than 80 suspects were charged out of the city’s more than 600 killings in 2017, a gap that contributed to a low clearance rate and left many families without legal resolution.

Did anyone who knew Lydell or was in his neighborhood that week notice anything that could help investigators?
