Dorchester woman found dead in house fire

Fire officials confirmed a woman was killed during a 2-alarm fire in Dorchester this morning.

The fire swept through a two-story residential building at 31 Greenwich St. The death marks the first fatal fire of 2015 in the city; there were four fatal fires in Boston last year.

The victim’s name has yet to be released. She was described by fire officials as “an older woman.” Firefighters responded to the scene, a white house with green trim, shortly after 6 a.m. By 8 a.m., windows of the structure were blown out and the exterior toward the back end of the building was ripped open, exposing a charred interior.

The Boston Fire Department estimates the blaze caused about $250,000 worth of damage. That department said the building was only home to one person. It was not immediately clear if that person was the victim; calls to Boston Fire were not immediately returned.

Fire, police and investigators from the Suffolk DA’s office are all investigating the incident. The Office of the Chief Medical Examiner is expected to determine the cause of death. Fire investigators, according to the DA’s office, will determine the cause and origin of the fire.
