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.

A former employee said she never saw the staff perform fire drills. The local fire chief pushed back at claims that dispatching more firefighters would’ve saved more lives.
