A woman who died three weeks after suffering severe burns in a fire on Minneapolis’ South Side last month has been identified as 54-year-old Debra Rae Erickson, authorities said.

Erickson suffered “thermal injuries” in the Feb. 3 fire, according to the Hennepin County Medical Examiner’s Office, which ruled the manner of her death as accidental. She was taken to HCMC, where she died on Feb. 26, an autopsy found.

Officials said the fire began at a townhouse in the 100 block of 31st Street W., in the Lyndale neighborhood.

Fire crews arrived to find Erickson standing outside, said Assistant Chief Bryan Tyner. She was taken to HCMC for treatment of her burns and smoke inhalation.

The flames were doused by firefighters, who saw that the fire was confined to a living room couch, Tyner said.

Tyner said investigators have yet to determine how the fire started.
