A fire that broke out near downtown Naperville Thursday night killed a 39-year-old woman who is believed to have been cooking at the time, according to authorities.
Firefighters were called to a three-story apartment building in the 100 block of Douglas Avenue just after 11:30 p.m. and found smoke rising from a second-story window, officials said.
Once in the unit, they found, "the kitchen was completely engulfed in fire" and firefighters "made a very aggressive attack," Chief Mark Puknaitis said.
An unconscious person was found in another room in the apartment and later pronounced dead at Edward Hospital. The DuPage County Coroner's Office identified the victim as Cariene Jones who lived in the apartment building.
Officials from the city, county and state partnered for an investigation and have deemed the fire accidental, Puknaitis said.
"It is cooking on the stove that appears to have caused the fire," he said.
Jones lived in the unit with her 16-year-old son who was not home at the time. Smoke alarms were working, but there were no sprinklers, according to Puknaitis. He commended a neighbor for calling 911 and knocking on doors to alert building residents.
"When we arrived on scene there were residents evacuated … I really believe he had some heroic actions in the whole process," Puknaitis said.
Damage to the building was estimated at $100,000. No one else was injured in the fire, but other residents have been displaced.
The fatal fire is the second in Naperville in about three months. In December, a blaze on Field Court killed two people immediately. A third person hospitalized after the fire later died.
