Fire officials said the cause of the fire that destroyed Crestline Elementary School could be released as early as Friday.
Vancouver Fire Department spokesman Scott Willis said that while he anticipated the announcement today, investigators said they were still following some leads and had some additional interviews to do today.
Fire investigators have been working to determine what started the blaze, reported at 3:17 a.m. Sunday, which destroyed the school, 13003 S.E. Seventh St. in the Cascade Park neighborhood.
About an hour after the fire was reported, fire officials escalated their response to the three-alarm fire, which means the agency called for reinforcements twice while it fought the blaze.
Nearly 500 students were displaced by the fire, but Evergreen Public Schools officials shuffled the students into other schools around the city, with classes resuming this morning.
