The Massachusetts assisted-living facility where a fatal fire killed nine people was caring for dozens of aging residents reliant on wheelchairs and oxygen tanks, but it lacked the safety measures and most of the staffing requirements that are commonplace in nursing homes.

Nine people died Sunday night after an assisted living facility caught fire in Fall River, Massachusetts, officials said, with elderly people begging for help from first responders as smoke poured out of the building.

The names of seven of the nine victims who died in a fire at an assisted living home in Fall River, Massachusetts,​ have been released by the Bristol County District Attorney.
