River Fire Chief Jeffrey Bacon deferred all questions about the fire investigation to the Massachusetts Department of Fire Services.

A fire broke out at about 9:30 p.m. on Sunday a Fall River assisted living residence, which drew nearly 50 firefighters to the scene and left a vulnerable population calling for help from their windows.

Flames roared through an assisted-living facility in Massachusetts, killing nine people and trapping residents inside, including some who leaned out of windows and screamed for help.
