Jon Taye Jamal Walker, 23, was fatally shot in Chicago on November 26, 2015.

Walker’s death is presented as one of many that contributed to Chicago’s escalating homicide rate in 2015, a period when efforts by law enforcement and community organizations were described as insufficient to stop the losses. The account links the increase in killings to broader community vulnerability and a reduction in proactive policing methods.

Does anyone have information about Walker, where he was that day, or the circumstances surrounding the shooting?
