A woman was found dead Thursday after an early-morning house fire in the Penobscot County town of Winn.

The Lincoln Fire Department responded to a house fire at 1115 Route 168 at about 1:30 a.m. Thursday, Maine Department of Public Safety spokesperson Shannon Moss said in a news release.

Five occupants escaped the home prior to firefighters’ arrival, Moss said, but first responders were told one woman was unaccounted for.

Investigators from the State Fire Marshal’s Office located a woman’s body in the debris at about 9:30 a.m., Moss said.

Her body was transported to the Office of the Chief Medical Examiner for identification and to determine her cause of death, Moss said.

The other occupants of the home suffered from smoke inhalation and were taken to a hospital in Lincoln, Moss said. They have since been released.

The cause of the fire is under investigation, Moss said. Fire crews were still monitoring the scene Thursday afternoon, the Lincoln Fire Department said in a news release.

Nearly 20,000 gallons of water were trucked to the scene from a dry hydrant on Phillips Road in Winn, according to the department. Route 168’s intersection with Phillips Road is about 4.5 miles away from the home.

The Central Maine Highlands Fire District and personnel from the Greenbush, Lee, Mattawamkeag, Milford, Millinocket and East Millinocket fire and rescue departments provided mutual aid, the Lincoln department said.
