FALL RIVER, Mass. — A 10th victim has died from the fire that ripped through a Massachusetts assisted-living facility earlier this week, officials said Thursday. Brenda Cropper, 66, died late Wednesday after being hospitalized in critical condition since Sunday's fire at the Gabriel House, Bristol District Attorney Thomas Quinn III announced.

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

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.

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.

Gabriel House residents described a chaotic scene Sunday night before they were rescued from the blaze that left nine dead and dozens more injured.
