A woman who was found dead when firefighters responded to a house fire has been identified and is believed to have set the fire, Surry County EMS Director John Shelton said. Firefighters came to a home at 264 Welcome View Church Road in the Dobson area after a passerby reported the fire at 1:48 p.m. Wednesday. Shelton said 39-year-old Lisa Kay White Johnson was pulled from the house but had already died. Shelton said investigators have determined the fire was intentionally set by Johnson. The fire started in a loveseat in the living room. Johnson was found in a bathroom.
