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 family of a resident at the Gabriel House assisted living facility has retained a law firm to investigate the circumstances leading up to the deadly Sunday fire that killed nine people and left dozens injured.

All 273 assisted living facilities in Massachusetts must send letters to all residents and families detailing fire safety protocols, evacuation procedures and key points of contact, the state announced Friday.

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.

A Massachusetts assisted-living center where nine residents died in a fire was cited for failing to immediately report more than two dozen health and safety incidents.
