When the deadly fire broke out Sunday night at Gabriel House in Fall River, Massachusetts, the assisted living facility had 70 residents and just two staff members working, according to the mayor and an employee.

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.

The state Executive Office of Elder Affairs cited the facility for seven deficiencies, four of which were repeat problems.
