Excerpts from abc7chicago.com:

A house fire has claimed the lives of all four family members of Chicago Firefighter Walter Stewart. The fire broke out just after 9 p.m. in the 2500-block of North Rutherford Avenue on Tuesday night. Everyone inside the home suffered severe smoke inhalation.

The blaze claimed the lives of Stewart’s wife, 36-year-old Summer Day-Stewart, who died on Friday, as well as the couple’s 7-year-old son, Ezra Stewart, who died on Wednesday. The two remaining children, a 2-year-old boy and 9-year-old girl — who have been hospitalized since the fire — passed away Friday night.

Ignite the Spirit, a Chicago Fire Department charity, has established a fund to support the family.
