PENDLETON, Ore.- Investigators now say they know what caused the fire at the Eagles Lodge Thursday night, nothing suspicious.
Investigators say a popcorn popper in the Lodge sparked the blaze.
Flames tore through the entire building. Four businesses were destroyed.
Now an employee of the lodge says he saw an industrial popcorn popper start to spark, and shortly after it burst into flames.
A fire extinguisher was used to try and put it out but it spread to the rest of the building.
Investigators believe it's a total loss, but they're glad it was the only building destroyed in the quickly moving blaze.
"The building is in the process of being secured, boarded up to eliminate a public hazard. The streets are being cleaned up and we're trying to get everything back to normal," said Pendleton Fire Chief John Fowler.
Water did get through some of the neighbor's windows, which caused some minimal damage.
Overall though, they're saying everybody's lucky a fire that spread so quickly was contained.
The fire didn't cause any injuries.
Insurance officials are expected on the scene Friday to officially assess the damage.
