Aaron Walker, 51, was fatally shot at his workplace, Kenny Pipe and Supply on Cowan Street in Nashville, during a dispute with a coworker on July 27, 2022. Described as friendly and genuine, Walker was born in Chicago on August 27, 1970, and had lived in Nashville since 2003. He married in 2012 and was a husband and father who also coached a little league football team in Antioch.

Metro Nashville Police identified a coworker, 53-year-old Ivan Maurice Coffman, as a suspect. Coffman was taken into custody and, after an interview with homicide detectives in which he admitted to having a disagreement with Walker before the shooting, was arrested and charged with criminal homicide based on that admission and other evidence in the investigation.
