Investigators are looking for the cause of a fire that heavily damaged a home in Campbell early Friday.

Firefighters, including those who were off-duty, were called out to a house on the corner of 14th Street and Gordon Avenue shortly after 3 a.m.

Flames had spread through the front of the home as crews from Struthers and Coitsville were also called to the scene.

No one was home at the time.  Firefighters are trying to contact the owner of the house.
