Elderly residents – some in wheelchairs and some dependent on oxygen tanks – were blinded by deadly smoke as they tried to escape an assisted-living facility in Fall River, Massachusetts, which caught fire Sunday evening.

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.

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