Firefighters battled a 2-alarm blaze early Wednesday morning at an abandoned lumber mill in Snohomish. The fire began at about 12:45 a.m. near Harvey Airfield east of SR 9. The first units on scene arrived to find the building engulfed in flames and called for additional help, going to a second alarm, according to Asst. Chief Jeremy Stocker with Snohomish Fire Dist. 22. The building used to be a lumber mill but was currently being used to store mattresses. "It appears there was a fire that started and got the mattresses going on fire," Stocker said. The intense flames prevented firefighters from getting inside the building and the fire was fought from the outside. There are no reports of anyone injured. Fire investigators will begin to look into the cause once the fire is sufficiently extinguished.
