Debbie Smith was 43 when her body was found on July 31, 2005, lying in the grass near a parking lot on Summit Avenue in Knoxville. Authorities determined she had been shot and her death was ruled a homicide.

Investigators questioned people closest to her: her boyfriend and her son were both extensively interviewed and later cleared. Detectives pursued a couple of promising suspects at one point but were unable to develop the evidence needed to link anyone to the scene, and the investigation grew cold.

The case remains open with the Knoxville Police Department, and officials have periodically asked the public for information that might lead to a break. If anyone knew Debbie, saw activity near Summit Avenue that evening, or has information that wasn’t shared with investigators, please come forward.
