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 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.

Flames roared through an assisted-living residence in Massachusetts, killing nine people, injuring 30 others and trapping residents inside.
