CEDAR HILL (CBSDFW.COM) – Teachers at a Cedar Hill elementary school spent Wednesday cleaning up, but not after students.

Someone broke in to Plummer Elementary School overnight, shutting power off to the building and knocking out security cameras.

They left behind shattered windows, broken equipment, and according to an administrator’s estimate, over $25,000 in damage.

Outside of the school, laptops and computers littered the ground, fire extinguishers and toys lay scattered, and students were all dressed up with no place to go.

Officials said the damage was so great, they decided to cancel classes Wednesday.

Students like 8-year-old Issak Embry learned the news as they got to school.  Issak worried the vandals might still be around. “I got my jacket over my head just in case.”

Many had stunned expressions as they filed inside the school.  The district did an inventory of the school a few months ago, so they are working on a list of what’s missing.

The school will open at regular time Thursday.  Good news for Issak, who said, “I like being educated.”

The Cedar Hill ISD is offering a $1,000 crimestoppers reward for information into the case.
