All 273 assisted living facilities in Massachusetts will be required to send a letter to all residents and families detailing fire safety protocols.

It’s very important in a crisis that people stay in contact,” Mayor Paul Coogan said in a wide-ranging interview from his office Friday.

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.

Video from police body cameras shows officers entering the building during the fire and assisting with the rescues of residents. (The Fall River Police Department edited this footage.)

Police released body-worn camera video showing rescues from the night an assisted living facility in Fall River, Massachusetts caught fire, killing at least nine people.

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.

More than 75 percent of Gabriel House residents are enrolled in Medicaid, state officials have said, and it charges significantly less than a typical assisted living facility does for private-paying patients.
