MINOT, Maine — Police and firefighters are at the scene of a house fire on Verrill Road. The fire was reported just before 2 p.m.

According to witnesses at the scene, the house is destroyed. Poland Fire Chief Mark Bosse said when firefighters arrived, the roof of the building was already fully engulfed.

According to dispatchers, Michael Callahan, owner of the house, was seen leaving the house Friday and was believed to be armed. He has since been taken into custody, after police searched for his vehicle along Route 119. Verrill Road is off Route 119.

A neighbor reported seeing the house on fire after Callahan left.

Callahan was charged last December with causing an armed standoff with police at the same home.

Callahan, 44, held police at gunpoint for more than six hours between Dec. 21 and Dec. 22 and was charged with six counts of reckless conduct with a firearm, two counts of domestic violence criminal threatening and one count of aggravated criminal mischief. Each count is punishable by up to five years in prison and a fine of up to $5,000.

He has since pleaded not guilty to those charges in Androscoggin County Superior Court and was out on $5,000 cash bail. He was ordered not to have contact with his wife, his daughter or his son.

According to Callahan’s attorney, James Howaniec, Callahan may be pursuing an affirmative defense of not guilty by reason of insanity.

Police were called to the Callahan home about 10:30 p.m. Dec. 21. A family member had fled the house when Callahan began shooting inside, police said. An overnight standoff ended peacefully with Callahan surrendering to police about six and a half hours later, after a tactical team member returned fire.

Callahan fired about a dozen rounds, police said, and an assault weapon was among the guns seized.

No one was injured during the standoff.

Last month, Maine’s attorney general said that Maine State Trooper Paul Casey was justified in firing at Callahan during the standoff.

Callahan is a former selectman in Minot and served on the RSU 16 board of directors. He left that board in 2004 after learning he could not serve on the board while his wife worked in that school district.

According to municipal tax records, the assessed value of Callahan’s two-story home is $159,000.
