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.

Authorities identified the victim as Brenda Cropper, 66. She had been hospitalized in critical condition since Sunday’s fire, which was the deadliest blaze in Massachusetts since 1984.

Dignity Alliance, an advocacy coalition, is calling on state legislators to ramp up assisted living laws based on forthcoming state report.
