"We haven't really investigated fully yet," Van Buren Volunteer Fire Department Chief Pete Taylor said, "but we're leaning toward electrical."
Firefighters were dispatched before noon Sunday afternoon to a fire at 897 E. U.S. 40, Brazil, in a home owned by Ed Sharton.
Sharton told The Brazil Times Sunday he was not at the home when the fire broke out. However, his family was at the home but escaped the house safely.
Sharton said earlier in the day, a breaker in the home would not reset properly.
Taylor said the fire was contained to a room above the home's attic. He added the dining room and kitchen contained water damage.
"The rest of the house seems to be in good shape," Taylor said. "They did a good job of stopping it."
Traffic on U.S. 40 was diverted temporarily as firefighters fought the blaze. Officials opened up the eastbound lane of U.S. 40, however, before 1 p.m.
Assisting at the scene included the Jackson Township Volunteer Fire Department, Dick Johnson Fire Department, TransCare and Clay County Search and Rescue.
