An apparently abandoned house at Simpson Road and Northside Drive went up in flames about 5:30 p.m. Tuesday. The building was totally involved by the time Lenoir City Fire Department firefighters responded just moments later. A nearby neighbor on Northside Drive, Billy Powell, said he had heard the property had been occupied at one point by homeless people, but police at the scene said it had not been determined whether the house was occupied when it burned, or what caused the fire. No one was in the structure at the time, according to authorities at the scene.
