CASCO – A fire that destroyed an old farmhouse and barn early Friday morning may be ruled arson, according to state fire officials.

The property at 509 Mayberry Hill Road has been vacant and without power for more than 40 years, said Dan Roy, a fire investigator with the Maine Fire Marshal’s Office. Because of this, he said, his preliminary report will state the the fire was “incendiary,” or deliberately set.

The fire was reported at 3:20 a.m. Friday by a couple living across the road from the farmhouse, Roy said.

There was no saving the structure, he said. “The building was completely engulfed in flames when the firefighters arrived on the scene.”

Fire departments from Casco, Naples, Raymond and Otisfield responded to the scene, according to Roy. Because there was no saving to house or barn, he said, firefighters concentrated on containing the fire as it threatened to spread across the lawn into nearby woods.

No one was injured, Roy said.

He identified the owner of the property as a David Gramstoff of Massachusetts, but declined to release Gramstoff’s address because he had not yet been contacted.

The farmhouse dated back to about 1822, Roy said, and was attached to a large barn by an ell. All that remains of the structures is part of a chimney that ran through the farmhouse, he said.

Roy said he has a series of interviews to conduct before putting together his final report, which he doesn’t expect to have completed until later next week.
