Tommy Allen Thompson, 26, was fatally shot on the evening of October 29, 2014, outside the South Bend Avenue Apartments in South Bend, Indiana. His father, Ricky Thompson, was also shot that night and survived his wounds.

Investigators publicly identified 28-year-old Brian Rankin as a suspect and later arrested him on charges connected to the shooting. Rankin’s background included prior charges for drug possession and an armed robbery with a firearm in Cook County, Illinois. In April 2015 the St. Joseph County Prosecutor’s Office dropped the charges because two key witnesses could not be located, leaving the case without a prosecution.

The killing left the Thompson family and their community without closure. Does anyone have information about the shooting or the witnesses who were expected to testify?
