WATERLOO – Authorities are investigating an overnight fire that damaged a duplex.
Crews with Waterloo Fire Rescue were called to 616 W. Sixth St. around 11:35 p.m. Monday and found fire coming from an upstairs window, said Battalion Chief Bill Beck.
No one was home in the second-floor apartment when firefighters arrived, and residents downstairs were able to evacuate without injury.
The flames burned through the roof and did extensive damage to the second floor. The first-floor apartment had water damage, firefighters said.
Heat from the fire damaged siding on a home next door.
The American Red Cross was called to provide emergency shelter for the displaced residents.
The cause of the fire hasn’t been determined.
