Treston Tullos, 39, was fatally shot in Chicago on January 16, 2017. His killing occurred during a month when the city was experiencing a rise in homicides compared with early 2016, amid a broader pattern of gun-related violence concentrated in many neighborhoods on the South and West Sides.

Police described this period as part of an ongoing struggle involving unresolved gang conflicts and the availability of illegal firearms. Tullos’ death is listed among the victims from that violent stretch, which officials and community groups were trying to address through reforms and outreach efforts.
