OKLAHOMA CITY - Around $1 million in damage was racked up after copper thieves hit three Oklahoma City Public Schools.
Oklahoma City Police said the thefts happened over spring break in mid-March.
The large air conditioners were destroyed after being stripped for the copper.
Moon Academy, Centennial High school and Classen School of Advanced Studies were hit.
OKC Police Master Sgt. Gary Knight said they are investigating a link.
"We don't have good suspect identification so we have to go with what we think, based on how they occurred, the M.O. of what was used and when they occurred, we believe that they're all related," he said.
Tierney Tinnen with the Oklahoma City Public School District said, fortunately, all of the schools are scheduled to get new air units under the new MAPS initiative and at no time was the comfort of any student compromised.
"All three sites had two chillers, so one was down and one was able to keep working so we haven't had any schools or kids without air conditioning," she said.
But Tinnen said the crime costs everyone.
"It's your money, it's your neighborhood school and they're coming in and stealing copper from your school, from your kids from our city from our community," she said. "They're stealing money out of your pocket."
