A resident is suing a Massachusetts assisted-living facility, claiming poor safety protocols left him trapped during the deadly fire.

A survivor of the deadly fire at the Gabriel House assisted living home in Fall, River Massachusetts is now suing the owner.

Bodycam footage provided by the Fall River Police Department in Massachusetts shows officers saving victims of the Gabriel House Assisted Living Facility fire on July 13.

All 273 assisted living facilities in Massachusetts will be required to send a letter to all residents and families detailing fire safety protocols.

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.

Officials announced a preliminary investigation shows a oxygen tank malfunction or smoking may have caused the deadly Fall River assisted living facility fire that claimed the lives of 10 last week -- and the presence of medical oxygen throughout the building likely fueled the massive tragedy.
