Northbrook firefighters were called to a house this afternoon at 2135 Brentwood Road for a report of smoke in the building. Reportedly there was nothing showing on arrival by Tower 12 but within minutes there was thick smoke everywhere. The alarm was upgraded to a Code 4 for the working fire, but after companies made entry, the source was determined to be the furnace.
Ann Madsen, shared some images from the scene as did Larry Shapiro.
