On September 15, 2005, Susan Barker, 63, and her husband Don Barker, 62, were found shot to death in their home on White’s Farm Road in Iredell County, North Carolina. The couple were discovered in their kitchen in what was described as an apparent double homicide that deeply affected the local community.

Forensic testing later linked the Barkers’ deaths to an earlier double homicide on January 21, 2005, when James Powell, 74, and Delet Powell, 71, were shot to death in their Union Grove home. Authorities say the same firearm was used in both crime scenes, which focused investigators on people who had access to both households.

After more than 700 interviews, police arrested 65-year-old Barbara Ann Evans of 138 Jennings Road on July 26, 2006, charging her with four counts of first-degree murder. She was known to frequent Barker’s Grocery and had been an acquaintance of both couples; the murder weapon was reportedly found during a search of her home. In 2009 a judge ruled Evans mentally unfit to stand trial because of dementia and the charges were dismissed.

Did anyone in the area recognize Evans from Barker’s Grocery or have information about her visits to the homes involved?
