Excerpts from abc7chicago.com:

Sauk Village Fire Department and auto aid companies were dispatched around 8:47 p.m. and arrived to a heavy fire through the roof of a single-family residential home. One occupant was outside of the residence and said that his wife was still trapped inside the home. Firefighters tried to locate the woman but had to evacuate the home when heavy fire overcame the crews. One firefighter experienced a minor injury from a small explosion. He was transported to a local hospital, where he was treated and released. A female resident died.
