Peggy Cox was killed on the evening of February 1, 1991, while working a late shift at the Hardee’s on Murfreesboro Road in Franklin, Tennessee. It was her 49th birthday and she had agreed to work that night; she lived in Lewisburg and had been employed at the Franklin restaurant for two years. A male voice used the drive‑thru intercom to place an order; when a vehicle described as a light‑colored, late‑1980s Nissan Sentra with a personalized plate reading Liz or Lisa pulled up, two gunshots were fired. Cox was struck once in the head and neck and was pronounced dead at a local hospital. Her son Jude, who was also working, found her moments after the shooting.

The case remains Franklin’s only unsolved homicide. No suspects have been publicly identified, no arrests reported, and investigators say no motive has been determined since nothing was taken from the restaurant. Authorities have pursued leads over the years, consulted outside forensic experts, and offered a significant reward for information leading to an arrest and conviction. If anyone remembers that vehicle, heard the call over the intercom, or has any other information, please share it with the Franklin Police Department.
