“Such nice women, it’s just unbelievable,” said Barbie Hogan, a home health aide. “Two sisters. . . I don’t know what one’s going to do without the other.”

Rinaldo’s 48-year-old son also lived with the women, but he was able to get out of the home before firefighters arrived.

“The fire did skip over to the building to the left of the original fire building but that was brought under control very quickly,” Sullivan told WBZ.

One firefighter was treated for heat exhaustion.
