Excerpts from fox32chicago.com:
Naperville firefighters were called at 1:25 a.m. for reports of a fire in a two-story home in the 1700 block of Baybrook Lane on Saturday. Crews found the fire in the walls of the attic with smoke coming from the chimney and roof line which they brought under control in about an hour. One firefighter suffered minor injuries at the scene.
Two adults and two children who were home at the time of the fire made it outside on their own. The home was rendered uninhabitable.
