Excerpts from chicago.CBSlocal.com:

Two people were found dead, and a child was injured, in a condo fire Monday morning in Glendale Heights. Three firefighters and a police officer also were injured. Numerous residents were displaced.

Police said, shortly after 10 a.m., officers and firefighters responded to the Waters Edge Condominiums complex on the 100 block of Dunteman Drive, where they saw fire in one of the condo buildings. The fire started in one condo before spreading to others.

As firefighters worked diligently to knock down the fire, neighbors said before crews arrived, they heard loud noises – possibly an explosion from the unit.
