Spokane Valley fire crews say they are still investigating the cause of a fire that fully engulfed a large barn near the Washington state line Monday afternoon. Firefighters say a neighbor called the fire in, and when fire crews first arrived they found the barn on E. Wellesley fully engulfed in flames. The owner was not home at the time. Firefighters were not able to enter the building until the fire was out, but say most of what was inside was farm equipment with hay on the second level. Animals were outside the barn, but firefighters say the animals were safe. No injuries were reported.
