Excerpts from abc7chicago.com:

Firefighters battled a blaze at a Forest Park home Thursday afternoon that started shortly before 5:45 in the 1100-block of Elgin Avenue.

A teacher, her husband and their 12-year-old son lived in the top unit of the home. A relative said the fire started in the attic, and while all three were able to make it out safely, they lost everything in the blaze.  What caused the fire is not immediately known. 

Relatives have started a GoFundMe to help the family displaced by the fire.
