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

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

According to Fire Chief Jeffrey Bacon, the blaze started in a room on the second floor on the east side of the Gabriel House building, but details about the exact origin and cause are under investigation.
