Officials with the Maryland State Fire Marshal's Office are investigating a fatal fire in Washington County early Monday morning.

Authorities say about 20 fire fighters from Potomac Valley, Brunswick, Sharpsburg, Neersville, Va. and Shepardstown, WV were dispatched to 1807 Back Road in Sharpsburg for a house trailer on fire. They had the flames under control within 15-minutes. "As they worked  the scene, they then determined there was the remains of body, unknown at this time as to whether male or female, located inside of the structure," says Deputy State Fire Marshal Bruce Bouch.

The body has been taken to the State Medical Examiner for an autopsy.

Bouch says the identity of the individual found inside the home is not known at this time, but Bouch says it could be the occupant of the house trailer. "Indications are that it may be the individual that is  registered in the tax records, but the Office of the Chief Medical Examiner will determine that to be the case or not, as well as the cause of death," he says.

Investigators say there is no evidence the home had any working smoke alarms, but there was a wood stove. Bouch says it's unknown at this time if that wood stove was connected to the fire.

Damage from the fire is estimated at $45,000. The cause and origin of the fire remain under investigation.
