DALLAS (CBSDFW.COM) – An 80-year-old woman died from burn injuries after a fire at a Dallas apartment complex Monday afternoon, fire officials said.

Firefighters responded to a fire at the Primrose Oaks Apartments in the 2500 block of Perryton Drive at around 1 p.m. Monday. When they arrived, they found smoke coming from a first floor unit in a two-story building.

Officials said the building’s sprinkler system had extinguished most of the flames, and that the fire was contained to a bedroom. Firefighters found the woman inside the bedroom and transported her to a hospital for burn injuries.

The woman, identified as Barbara Louise Reeves, was pronounced dead at the hospital Tuesday morning.
