Vandals smashed at least 20 windows and trashed two classrooms at Nisqually Middle School in Lacey overnight.
School officials said three vandals overturned desks, knocked books off the shelves, and tossed items around the classrooms in a portable building. A microwave oven was also destroyed, but nothing was reported stolen, said spokeswoman of North Thurston Public Schools, Courtney Schrieve.
Surveillance video released by the school late Thursday shows two vandals approach and throw a rock through the glass door at the front of the school.
The second vandal picks up the rock and throws it again only to have it bounce off.
As his accomplice on the left breaks another window he picks up his rock and throws it one last time at the glass.
The vandals then moved to a portable that contains two classrooms, trashed them and then pulled the fire alarm, school officials said.
Firefighters arrived to find the damage and deputies arrived soon after.
Crews were called out to the school at 3:30 a.m. to start cleaning up and repair the damage before school started.
Scrhieve said the crews have done a good job making repairs and getting the school ready for students today.
At this point the total cost of the damage is estimated at $15,000.
"They’re just taking away from our education, and money from our education, and supplies we could have spent that money on," said student Sierra Dabe.
The Thurston County Sheriff's Office is investigating the vandalism.
