Nine people died Sunday night after an assisted living facility caught fire in Fall River, Massachusetts, officials said. Elderly residents begged for help from first responders as smoke poured out of the building and blackened the hallways they tried to use for their escape.

The investigation into the fire’s cause is ongoing but “does not appear to be suspicious,” according to the Bristol County district attorney's office.
