Authorities say a fire that displaced two families this week in Dubuque was caused by the improper disposal of smoking material. No injuries were reported in the blaze at a residence on Loras Boulevard. Firefighters were dispatched just before 4pm Tuesday to a fire on the third floor of a three-story, multi-family residence. Crews helped evacuate five occupants from the first and second floors of the building. The fire was contained to one room on the third floor of the structure. Additionally, two adults living on the second floor temporarily were displaced due to water damage.
