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.

Nine people have been killed and dozens are hurt as a fire tore through an assisted-living facility in Fall River, Massachusetts, officials said.

An investigation into the source of the fatal fire at a Massachusetts assisted living facility last week classified the cause as "undetermined," though officials believe it was an accidental ignition

Members of a commission working on new regulations that would change the way assisted living facilities are run will delay their report by at least 90 days.

Brenda Cropper, 66, died at a hospital after being in critical condition all week after the fire erupted on Sunday, officials said.

Nine people died and dozens were hurt in a fire at the Gabriel House Assisted Living Facility, and finger-pointing has already begun over whether there were enough firefighters to respond and whether staff at the facility did enough to help.

The Fall River assisted-living facility where a fire killed 10 people temporarily lost its certification nearly a decade ago.
