The Massachusetts State Fire Marshal's Office says a fire that killed two people in Northbridge Saturday morning is not considered suspicious.
Responding firefighters said they didn't hear any alarms going off, which leads investigators to believe that there were no working fire detectors on the side of the home where the fire began. The damage upstairs was too extensive to locate any, and a single detector in the basement did not have any batteries inside.
The fatal fire broke out around 3:20 a.m. at 73-75 Border Street in Northbridge. Two residents were able to escape, but two others passed away in the blaze.
The investigation is on-going.
