Dr. Frank Shemwell, an 81-year-old retired physician, was found dead after a house fire in Paducah, Kentucky, on July 24, 2006. Firefighters discovered his burned body on the kitchen floor. The medical examiner later determined the death was a homicide: Shemwell had sustained blunt-force trauma and was still alive to inhale smoke as the fire took hold of the home.

Investigators questioned people close to Shemwell, including his then-wife Penny Baird Shemwell, who was described as a person of interest; no charges in the homicide were filed. Penny was later convicted of unrelated felony shoplifting and unlawful possession of a handgun and served a prison sentence. No arrests have been announced in the murder of Dr. Shemwell and the case remains unsolved.
