Nine people have died after a Massachusetts assisted living facility caught fire Sunday night. The death toll was revised after an error from the district attorney’s office on Friday. Elderly residents rushed to their windows to scream and beg for help as smoke filled the hallways.

Assisted living centers are rare in Mass, but many families still don’t know what they offer — or what they don’t.

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.

The Bristol County District Attorney's Office said that a "miscommunication" led them to previously report that Brenda Cropper, 66, had died, when in fact she is still alive and in critical condition.

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.
