After spending days in critical condition, Brenda Cooper, 66, succumbed to injuries she sustained on July 16, officials said.

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

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 Massachusetts assisted-living facility that caught fire Sunday evening was slated to undergo a recertification and compliance review process later this year.

A tenth victim has died following the Fall River fire at the Gabriel House Assisted Living Facility on Sunday, the Bristol County DA announced Thursday morning.

The Massachusetts assisted-living facility where a fatal fire killed nine people was caring for dozens of aging residents reliant on wheelchairs and oxygen tanks, but it lacked the safety measures and most of the staffing requirements that are commonplace in nursing homes.

The Fall River mayor’s office has confirmed all Gabriel House residents displaced by the tragic Sunday fire that claimed nine lives now have new living arrangements.

Authorities identified the victim as Brenda Cropper, 66. She had been hospitalized in critical condition since Sunday’s fire, which was the deadliest blaze in Massachusetts since 1984.

Investigations into what starts a fire require a methodical look at the scene and can take a long time to complete.
