A fire this week that killed nine residents at a Fall River assisted living home has raised new questions about whether the 273 such residences in Mass. are properly staffed and equipped.

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

Hundreds lined up outside the St. John Athletic Club Friday evening for a fundraiser benefitting residents of the Gabriel House assisted living facility, which caught fire earlier this week.

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.
