EASTON, Maine — Two brothers were killed, but eight other people managed to escape a home destroyed by fire on Richardson Road early Tuesday morning.

Paul Beaton and Mark Beaton, both believed to be in their early 50s, were killed in the blaze that was reported at 5 a.m., according to Easton Fire Chief Kim White. Mark Beaton owned the home.

Eight other people were in the home at the time of the fire, according to White. He said he did not know whether all had been living at the home or whether some people had been visiting. The eight who escaped the fire had gotten out safely by the time firefighters arrived.

Investigators from the state fire marshals office spent the day on the scene of the first fatal fire in Easton since 1959, according to White. As of Tuesday afternoon, they had not determined a cause for the fire.

There were no working smoke detectors in the home.

“It was fully involved when we got there,” White said.

Department of Public Safety spokesman Stephen McCausland said the survivors were being interviewed.

“Of benefit to us is that we have eight people who can help us determine what happened and where the fire might have started,” he said Tuesday afternoon.

Firefighters from Mars Hill, Fort Fairfield and Presque Isle provided mutual aid.

White said the house was once a single-story dwelling but had been built onto several times over the years, which made the blaze difficult to fight.

A dog also died in the fire, but firefighters saved a kitten.

Police and other emergency vehicles blocked off Richardson Road for much of the day while investigators and firefighters worked.

The American Red Cross was assisting the survivors of the fire. White said he does not think the home was insured.
