KNOX, Maine — The State Fire Marshal’s Office has determined that a fire that destroyed a house on Aborn Hill Road last week is a case of arson.

Sgt. Kenneth Grimes, senior investigator for the fire marshal’s central division, said Friday that the fire on May 7 destroyed a home on Aborn Hill Road owned by Dan Labree, who was away at the time of the blaze.

Grimes said the one-story house burned to the ground.

“There was no operating power to the building, and no heat sources inside” [that might have caused a fire], he said. “We can’t say where the fire started.”

Grimes described the scene as a rural area. No one was in the house at the time or believed to have been for two days, he said.

The blaze remains under investigation by Investigator Scott Richardson of the central division, Grimes said.

Fire departments from Thorndike, Freedom, Unity and Brooks responded to the call, which came in at 10:41 a.m. Thursday, May 7, according to the Waldo County Office of Communications.

Dan Labree is the son of the late state police Detective Otis Labree, who was the department’s first detective in 1955 and later named Legendary Trooper in 1999, according to a news release from Stephen McCausland of the Maine Department of Public Safety.
