A woman was killed after a fire broke out in her Natick home Saturday morning, authorities said.
An off-duty firefighter discovered the fire at 211 East Central Street around 8 a.m. while on his way to work, state fire officials said.
Carol McCarthy, 73, was found unresponsive inside her Natick home, according to the Middlesex County District Attorney’s office.
Firefighters rescued her through a second story window. She was then rushed to a local hospital where she pronounced dead.
There was evidence that the smoke alarms in the home were not working, according to state fire officials, which they said is a common thread among the recent fatal fires in Massachusetts. Fires in North Andover, Plymouth, and Fitchburg this month each left one person dead.
McCarthy’s death is the 12th fire death in Massachusetts this year, fire officials said.
State fire marshal Peter Ostroskey emphasized the need for working smoke detectors in homes.
“We’ve had a real tough February, so far as fire deaths,’’ he said.
Ostroskey said the investigation into the cause of the Natick fire is underway.
