Much of the vandals' work was caught on surveillance video and police are now looking for help to identify the suspects.
The damage was first discovered by staff and players for the girl's basketball team that had gathered at the school for an early morning practice. There was no school Monday due to it being Presidents' Day.
Platte City Police reviewed the surveillance video through the day Monday looking for clues.
"You can see the Adidas logo," said Lt. Albert DeValkenaere referring to the video of the matching hoodies the suspects were wearing on their tear through the school.
Lt. DeValkenaere says the two entered the school shortly after 4 a.m. Monday. With their faces covered by bandanas, they broke in through a window on the back side of the building that entered into a computer lab.
They damaged several of the monitors in that lab," DeValkenaere said. "They disassembled some of the computers and stole computer parts."
That was just the beginning of their trip through the school. Vending machines and video cameras were damaged and there was graffiti written on many of the walls.
"They also broke into a utility closet where they damaged the school's telephone system," DeValkenaere said. "From there they wandered around the school and broke into several administrative offices."
Laptops, tablet computers and cash were also taken.
The suspects are described as white, thin-build males, in their late teens or early 20s.
"They could possibly be from the high school," DeValkenaere said. "They knew their way around."
In all, the vandals rampage through the school took about three hours. The damage is estimated to exceed more then $50,000, though that number might go higher. Police hope by getting the video out to the public, someone will recognize who the two culprits are.
"Hopefully there might be somebody who might recognize the clothing or the mannerisms," DeValkenaere said. "These individuals can be seen walking up and down the hallways coming and going in the video. I hope somebody can say, 'I know that person.' "
Meanwhile, news of the vandalism spread through Platte City quickly. At the local Price Chopper grocery store, several employees attend the high school
"It's pretty crazy. I wouldn't think someone would stoop that low to do something like that," said Taylor White, a senior at Platte Co. R-III.
Because of the vandalism, the school's girls basketball game Monday night with Liberty North was moved to the junior high gym.
Media were not allowed to attend the game and school officials made no comment about the incident.
