Excerpts from abc7chicago.com:

A woman was found dead after a house fire in Brookfield. The fire broke out early Sunday in the 4300-block of Arthur Avenue. Firefighters arrived at about 6:30 a.m. to find heavy flames and thick black smoke. 

Neighbors told firefighters that there could be a woman inside the home, but firefighters were prevented from initially going in because of the flames. They eventually found the homeowner dead on the first floor. The woman has been identified to the Cook County Medical Examiner’s Office as 53-year-old Susan Colby. It was immediately unclear what caused the fire.
