The cause of a deadly fire​ at the Gabriel House assisted living home in Fall River, Massachusetts has been narrowed to two possibilities.

More information on the cause of the deadly Fall River fire at Gabriel House on July 13 was released Tuesday. During a press conference Tuesday afternoon, officials said evidence narrowed the cause down to two possibilities, either an electrical or mechanical failure of an oxygen concentrator or the improper use or disposal of smoking materials.

At a press conference Tuesday, July 15, outside FRFD headquarters, Bacon said the city has typically relied on overtime for coverage in the event of a crisis -- but in an event like the Gabriel House “you can never have enough staff,” and that he is primarily focused on the lives that were saved.
