Investigators are looking into a number of issues including the possibility that the fire was caused by smoking near an oxygen tank.

FALL RIVER, Mass. (AP) — A 10th victim has died from the fire that ripped through a Massachusetts assisted-living facility earlier this week, officials said Thursday.

The footage, released Thursday afternoon, shows Fall River police officers and firefighters alerting and rescuing residents from the assisted living facility.

Officials announced Wednesday that the fire at the Gabriel House assisted living home in Fall River, Massachusetts that killed nine people led to an agreement to make staffing additions to the Fall River Fire Department.

The scene outside Gabriel House, the assisted living facility that saw a deadly fire over the weekend, was solemn Wednesday, as mourners placed flowers and lit candles, some praying, others standing silently, some imagining the scene over the weekend that left nine residents dead.

The owner of an assisted-living facility in Fall River where nine died in a fire also owns an adult foster care business in Worcester.
