Knoxville (WVLT) - Investigators say arson may be the cause of a car fire that quickly caught the side of a house on fire Friday night in Knoxville.
It happened just after 8 o'clock, off Marble Hill Boulevard.
Neighbors say a man and woman were fighting and they think the female poured gasoline on the car.
When it ignited, it quickly caught this house on fire and the heat melted the siding.
Neighbors say police have been to the home several times to settle arguments between the couple.
Knoxville police and fire fighters are investigating.
