Excerpts from wgntv.com:

Schaumburg police officers arrived at 6 Treebark Drive just after 9:20 p.m. Friday evening for a reported fire and observed flames and smoke emitting from the home. They found an 87-year-old man inside and were able to safely evacuate him. The man indicated his wife was still upstairs in the house. An officer attempted to proceed upstairs, but was overcome by heavy smoke and evacuated.

Firefighters arrived and later recovered the victim from upstairs. The 84-year-old woman was pronounced dead at the scene.

The 87-year-old man was transported to the hospital and treated for non-life threatening injuries. One officer was also transported for smoke inhalation and was later released.

The cause of the fire has yet to be determined and remains under investigation.
