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.

Flames roared through an assisted-living facility in Massachusetts, killing nine people and trapping residents inside, including some who leaned out of windows and screamed for help.

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.
