Officials said the blaze began around 12:30 a.m. Friday in the main bedroom of Carole Ann McKenzie's home. The fire then moved to the living room, where it destroyed furniture and electronics.
The blaze required about 25 firefighters to extinguish. No one was hurt, but not much in the home was salvageable, officials said.
``The sad part is that the Christmas tree and presents were all destroyed,'' said Mike Moser, a fire department spokesman.
Investigators said they suspected foul play or an accident started the fire, but they were still determining the cause.
``It could be something that was thrown in the house or it could be a cigarette,'' police spokesman Sgt. Rich Nicorvo said.
Police have visited McKenzie's house on several occasions in response to domestic disturbance complaints, Nicorvo said. A relative declined to talk to a reporter Friday afternoon.
The American Red Cross has provided McKenzie and her children with a hotel room, clothes, shoes and grocery money to last until Monday.
