Niko L. Walker, 21, was shot and killed in Chicago on December 25, 2016. He was found with fatal gunshot wounds and succumbed to his injuries during a Christmas weekend that saw at least 60 people shot across the city, 11 of whom died. Walker’s death was one of many homicides that contributed to a sharply higher homicide count for Chicago in 2016, a year marked by a surge in shootings and killings attributed in reports to gang activity and disputes. The Chicago Police investigated the crime scene, and Walker’s memorial later appeared on Find a Grave.

What information can anyone share about Walker’s life, where he spent time that season, or about witnesses who might have seen what happened that day?
