“The woman was the sole occupant of the home at the time of the fire,” said Westwood Chief of Police Jeffrey P. Silva. “Tragically, the woman’s injures were visibly mortal, and despite a dangerous and heroic attempt to rescue her, the woman was evaluated and pronounced dead at the scene from her injuries.”

The cause of the fire is still under investigation, but State Police and the State Fire Marshall’s Office say it may have started in the kitchen while the woman was cooking.
