Questions and finger-pointing have increased in the days since a fire at a Massachusetts assisted-living facility killed nine and hurt dozens.

More than 75 percent of Gabriel House residents are enrolled in Medicaid, state officials have said, and it charges significantly less than a typical assisted living facility does for private-paying patients.

Questions about Gabriel House living conditions and emergency preparedness continue to swirl following Sunday’s deadly fire.

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 investigation into the fire’s cause is ongoing but “does not appear to be suspicious,” according to the Bristol County district attorney's office.
