Classes were canceled Monday at a Mukilteo school after an arson damaged buildings and shut down the school's phones and internet service.
The fire was reported late Saturday night at Columbia Elementary School on Harbor Pointe Boulevard.
Investigators say someone set two portable toilets on fire.
The flames spread to the exterior of the building and traveled up into the eaves, ruining computer and electrical equipment. That sent heavy smoke into the school's kitchen and gym area.
"We just had our family fun night here on Friday night," said parent Randi Seaberg. "We had hundreds of families come and just celebrate the end of the school year, so to have something like this occur right after a really nice event is even more upsetting."
"It's sad because there are so many other things that you could do besides burning down buildings," said fourth grader Kari Seaburg. "I don't know what else to say, but it's really sad."
School district spokesman Andy Munz said the exterior of the school sustained most of the damage, while the interior of the school suffered smoke damage. Classes are canceled Monday due to damage done to the school's fiber optic line, which knocked out telephones and internet service at the school.
Crews will spend Monday assessing the damage and making repairs to the telephones and internet service. The fire caused an estimated $100,000 in damage.
Monday's school cancelation had parents scrambling.
"It's going to be a bit of recalculating our childcare plans for tomorrow," said Seaberg. " Our students were supposed to be starting state testing and this is really disruptive to that. It’s just disruptive to the whole community."
