Investigators ruled the fire accidental, “caused by the failure of an electrical extension cord,” the statement said. The department previously described “hoarding conditions” inside the home, which did not have functional smoke detectors, according to Thursday’s release.

Fire officials identified the woman who died as Janet Pereira, 74, and said she was found dead on the first floor of the home. Fire officials said firefighters encountered hoarding conditions inside the house, and, as a precaution, took a defensive posture to fight the fire from the outside.
