PLAINVILLE, MASS. (WHDH) – A Plainville woman has been charged with arson following a Monday morning fire that displaced more than 20 residents.

Heather MacKinnon, 61, faces multiple charges after officers’ investigation indicated the fire was “deliberately started” and that she was the responsible party.

Plainville Fire responded to Messenger Street at 5:15 Monday morning after a report of a fire with residents possibly trapped. The response drew crews from six additional cities.

“Firefighters were able to contain the fire to one apartment, but extensive smoke and heat damage spread throughout the building,” Plainville Fire said in a statement. “After several residents were evaluated for smoke inhalation, no serious injuries were reported and a pet was rescued and treated by EMS.”

MacKinnon was located in North Attleboro and taken into custody. She is charged with arson of a dwelling, malicious destruction of property and disorderly conduct. She is to be arraigned in Wrentham District Court.
