Charles R. Johnson, 41, was fatally shot on November 28, 2016, on Chicago’s South Side. Johnson was found with multiple gunshot wounds and died after emergency responders arrived. The case is described as part of a broader surge of homicides in Chicago during 2016, with the South Side among the hardest-hit areas.

Investigators encountered a lack of witness cooperation in this case, a barrier that is said to impede many local homicide investigations and complicate efforts to solve shootings and provide answers to victims’ families.

If anyone has information about Charles R. Johnson’s death or saw anything in that South Side neighborhood on or around November 28, 2016, please come forward with tips.
