KNOXVILLE – Four Knoxville residents are displaced after a house fire on Saturday resulted in their home being deemed a total loss.

According to the Knoxville Fire Department, crews were dispatched to the 400 block of S. 7th Street on Saturday morning at around 9am following reports of a structure fire. When crews began to arrive on scene, they requested additional backup, as smoke was billowing high into the sky.

Crews found a two-story home with extensive fire coming from the roof and the rear side of the home. As they were fighting the blaze, crews noticed that the roof of the home had started to collapse, and they were thus pulled from the home. Master streams were eventually able to put most of the fire out in around 10 minutes. The fire was brought under control in roughly 45 minutes after the scene was secured and salvage operations began. The home and its contents were deemed a total loss.

The Knoxville Fire Department reports that the home had four residents, and they are now displaced and receiving assistance from the American Red Cross and First Resources Corporation.

The exact cause of the fire remains unknown at this time and is currently under investigation.
