A woman previously reported to have died after a fire at a Fall River assisted living residence remains in critical condition, the district attorney's office said.

FALL RIVER — The nine residents killed in a fire here at Gabriel House, an assisted living residence, are being remembered as fonts of knowledge and symbols of longevity.

The mayor of Fall River said only two people were working at the Gabriel House in Fall River when a fire broke out Sunday night, killing nine residents​ at the assisted living facility.

Investigations into what starts a fire require a methodical look at the scene and can take a long time to complete.

Despite efforts by scores of firefighters – nearly half of whom were off duty at the time – and “every police officer in the city,” nine Gabriel House residents died in the fire, according to officials. Those killed range in age from 61 to 86. Dozens of others were injured, one critically.
