(WBIR) Investigators with the Knoxville Fire Department are trying to determine what caused an overnight apartment fire.
Just after midnight, fire fighters were called out to the Walter P. Taylor housing complex on McConnell Street.
When fire fighters arrived, they saw heavy smoke coming from two-story apartment building. Crews had to make a forcible entry and were able to quickly put out out the flames.
No one was in the apartment when the fire started. No word on what started the fire.
