The fire was reported last night around 10:30 on the Barrows road in the Oxford County Town of Sumner.

Public Safety Spokesman Steve McCausland says the occupants of the home are currently unaccounted for.

The occupants of the home are believed to be brother and sister and McCausland says fire investigators with the state Fire Marshall's Office will be aided by an excavator to search the rubble of the two-story home that was flattened by the fire.
