A Tuesday morning fire that damaged two mobile homes off Oliver Springs Highway has been ruled suspicious, and detectives from the Anderson County Sheriff’s Department will investigate, a report said.

The fire was reported at two mobile homes at the end of Joann Lane, just west of Anderson Memorial Gardens, at about 3:30 a.m. Tuesday.

Anderson County Sgt. Mark C. Hobbs said one of the mobile homes was unoccupied and used to store parts, including doors, cabinets and paint. It is owned by Ben Graves of Ben’s Home Center and located next to a fenced-in storage area.

Graves estimated the home’s value at about $18,000. The value of the items stored inside was unknown, the Sheriff’s Department report said.

There was a second “very old” mobile home behind the first one, and it appeared to be the source of the fire, the report said.

Neither mobile home had power. The report estimated the total damage at about $21,000.
