A woman previously reported to have died after a fire at a Fall River assisted living residence remains in critical condition, the district attorney's office said.

The nation's largest injury law firm announced Friday it was investigating the fatal fire in Fall River Sunday night.

A 10th victim has died from the fire that ripped through a Massachusetts assisted-living facility earlier this week, officials said Thursday, as records and accounts from staff raise concerns about conditions at Gabriel House before the blaze.

The one-page inspection report released Thursday morning showed the Gabriel House also had an adequate number of fire extinguishers, along with alarms for heat, smoke, and carbon monoxide. The inspection noted the facility had generally good housekeeping, with nothing blocking exits or stairways.

There’s no doubt in my mind that that fire was destined to kill 50-plus people,” Fall River Fire Chief Jeffrey Bacon said Wednesday.

Questions and finger-pointing have increased in the days since a fire at a Massachusetts assisted-living facility killed nine and hurt dozens.
