A fire killed a woman in Tangipahoa Parish early Friday morning, the State Fire Marshal’s Office said.

About 2 a.m., crews were called to a blaze at 46485 Durbin Road in Natalbany, according to a news release. When they arrived at the home, a parish deputy told them four people had escaped, but one was still trapped inside.

Firefighters found Yolanda Dyson, 39, near a window in her bedroom, but she was pronounced dead at the scene, the Marshal’s Office reported. Two other people were treated for minor injuries.

Investigators believe the fire was caused by an electric space heater.

Dyson shared the home with her mother, Brenda Kinchen, and three unnamed children — ages 11, 12 and 15 — described as Kinchen’s grandchildren.

The release states the 15-year-old was asleep on a couch in the living room when she woke up “after experiencing an intense amount of heat to her feet.”

The girl saw one of the space heaters in the home was on fire, and yelled out to warn other people in the house, the Marshal’s Office reported.

Investigators said the home had smoke alarms, but they were not working at the time of the fire.
