Theresa Mcmullin, called Terry by some, was 63 when she disappeared from her self-built cabin in Sevier County, Tennessee on September 12, 2010. First responders found the cabin largely destroyed by a fire that had smoldered for some time, but repeated searches of the debris turned up no human remains and her car was still in the driveway. Investigators concluded she likely was not inside when the blaze started and have treated her disappearance as suspicious.

Theresa reportedly lived alone, had health problems that required oxygen and several medications, and neighbors told investigators that people had been sneaking into her home at night to steal those medicines in the weeks before she vanished. Her son, who lived nearby, was arrested at the scene on unrelated charges. A state bomb and arson report later ruled the fire’s cause undetermined.

Extensive searches in 2015 in parts of Cocke County and the Great Smoky Mountains National Park did not locate any remains. The investigation remains open and authorities say someone in the community may know what happened. If anyone has information about Theresa, where she spent time, or suspicious activity around September 2010, please share what you know.
