BOSTON (WHDH) - A raging fire at a three-family home in Dorchester spread to adjacent buildings and a car early Friday morning, leaving 19 people displaced.

Firefighters responding to a reported fire at 24 Fairmount St. around 4:40 a.m. ordered a fourth alarm as they battled the fast-moving flames that had spread to 20 Fairmount St., 26 Fairmount St., a garage in the rear of 28 Fairmount St., and a car in the driveway, according to the Boston Fire Department.

Porches in the back of 24 Fairmount St. collapsed after the rear of the house became fully involved in fire.

Nineteen people were forced out of their homes, including two children.

There were no reported injuries.

Kristen Handricken rushed out of her house as flames began to approach it.

“It sounded like gunshots but it was just the windows popping,” she recalled. “That’s when we saw orange flames heading toward my kitchen. My windows started to crack and pop and we just started to call and yell.”

Around 100 firefighters responded to the scene to contain the fire.

The blaze left behind roughly $2 million worth of damage.

The cause remains under investigation.

No additional information has been released.
