A 59-year-old woman was found dead when a fire broke out at a home on the far Northwest Side Thursday morning, fire officials said.

The blaze erupted about 5:51 a.m. at a single-story home in the 5000 block of North Mobile Avenue in the Jefferson Park neighborhood, according to Fire Media Affairs.

Firefighters found a person dead at the scene, fire officials said.

The home did not have any smoke detectors, Fire Media Affairs said.

A representative at the Cook County Medical Examiner’s office said he had not been notified of the death.

The cause of the fire remained under investigation Thursday morning.
