FEDERAL WAY, Wash. — A fire at a vacant commercial building in Federal Way was ruled arson by the King County Sheriff’s Office.
Crews were called to Pacific Highway South and South 279th Street about 3 a.m. Thursday and found heavy flames and smoke coming from the building.
Firefighters said they were unable to search the building to see if anyone was inside because the damage from the fire made it unsafe to enter.
Video from South King Fire showed the building collapsed.
Anyone with information is asked to call the Federal Way Police Office or the Arson Tip Line at 1-800-55-ARSON.
