Fire officials say they think a piece of malfunctioning equipment started a Saturday fire that burned a new sawmill to the ground in northwestern Wisconsin.
Fire crews from seven different departments spent five hours on the scene in Cornell.
The building is a complete loss and three semi-trailer trucks sitting next to the mill were destroyed.
Firefighters did manage to preserve another big truck parked near the burning structure.
None of the 55 firefighters who battle the flames were injured.
