Daniel A. Walker was 23 when he was shot and killed in Chicago on March 23, 2012. The shooting occurred in a neighborhood significantly affected by gang-related activity during a year when the city was experiencing a rise in homicides and gun violence. Walker’s death contributed to Chicago’s alarming total for 2012, a year that recorded over 500 homicides.

Reports say solving cases like Walker’s was hampered by a lack of witnesses and limited cooperation in gang-dominated areas, leaving many victims’ families without answers. Does anyone have information about Daniel Walker, his last known whereabouts, or the March 23 incident that could help bring clarity to the case?
