Excerpts from abc7chicago.com:

A Chicago firefighter’s wife has died from her injuries days after her son was killed in a Northwest Side fire.

She has been identified as 36-year-old Summer Day-Stewart. Her 7-year-old son, Ezra Stewart, also died after the Montclare house fire on Tuesday night. Ezra died at 6:25 p.m. Wednesday at Loyola University Medical Center in Maywood.

Two other children were critically injured in the fire, which broke out just after 9 p.m. in the 2500-block of North Rutherford Avenue. Everyone inside the home suffered severe smoke inhalation.

A deceased pet was also seen being removed from the home Wednesday morning.

Chicago fire officials passed out smoke alarms and fire prevention materials near where the fire occurred, as they always do after a deadly blaze. It’s a reminder to check devices and change batteries in the detectors, especially as we approach the time change weekend.

The home involved in the fire did have detectors.

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

Fire inspectors are working on determining the cause of the fire. Investigators wouldn’t say whether or not the fire was intentional as the cause remains under investigation.
