NEW HAVEN, Conn. (WTNH) — A woman is in critical condition at the hospital following a fire at a multi-family home Monday morning on Quinnipiac Avenue in New Haven.

Crews were called to the building at around 9 a.m. for the report of people trapped. Firefighters were able to help residents get out of the house.

A woman rescued from the house was taken to the hospital, where New Haven Fire Chief John Alston said she was in critical condition.

The patient was later transported to Bridgeport Hospital. There is no further update on her condition.

“Heavy fire on the first floor. It appears to be a room and contents fire… that moved to the structure,” Alston said. “Obviously, they’re doing some type of overhaul now to make sure extinguishment is complete.”

The American Red Cross is helping six people displaced by the fire.

Fire officials said the homeowner’s dog was killed in the blaze.

It is not yet clear how the fire started, officials are still working to determine a cause.
