OLD ORCHARD BEACH (AP) – Investigators confirmed Thursday that the three people found dead in a suspicious house fire the previous evening were members of the family that lived there.

State police identified the victims as local businessman Christopher Bolduc and his wife Carol Bolduc, both 42, and their 15-year-old son, Joshua.

Lt. Brian McDonough of the Maine State Police said the fire has been categorized as suspicious, but he would not elaborate. He declined to comment on where in the home the bodies were found or provide any details of the fire scene.

“We want to proceed as cautiously as possible,” he said.

McDonough said detectives had interviewed the family’s friends, neighbors and associates as well as an older son, Matt Cushing, a University of Maine student who was informed of the tragedy and was with his extended family.

Investigators were awaiting autopsy results from the state medical examiner’s office in Augusta, where the bodies were taken after Wednesday’s fire.

“It’s very premature to consider anyone a potential suspect,” McDonough said.

McCausland said the Cape Cod-style house was in a fairly new residential neighborhood near a golf course in the resort town, which has a year-round population of nearly 9,000. Chris Bolduc operated two novelty shops near the Old Orchard Beach pier and his wife was president of the local neighborhood association.

Deputy Fire Chief John Fitzgerald said firefighters were called to the home around 6 p.m. Wednesday and found three bodies inside before they extinguished the fire, which took about 20 minutes.

The blaze left the house heavily damaged inside, but the walls and roof were still standing, said Stephen McCausland, spokesman for the Public Safety Department.
