Vandals emptied at least eight fire extinguishers inside Wade King Elementary in Bellingham early Sunday morning, officials said.
Almost all of the damage was cleaned up by Sunday and school will go on as scheduled Monday, according to the Bellingham School District.
This is a place where people work hard to help kids learn, said Assistant Superintendent Ron Cowan, To think someone would do this in a school is very disappointing.
In addition to spreading the white powder from fire extinguishers throughout of the school, vandals also smattered paint on some of the walls. A small swastika was carved into a desk. Cowan said it appeared nothing was stolen.
The school district is offering an $1,000 reward to anyone with information on the crime.
The school is named after the 10-year-old boy who was killed in the 1999 explosion of a fuel pipeline that also killed Wade King's friend Stephen Tsiorvas, and 18-year-old Liam Wood. The blast sent a plume of black smoke 30,000 feet into the air.
