"We just completed a two-year, two-phase, large renovation project," said Jeanne Collins, the superintendent of Burlington schools.
Kindergarten through fifth-grade students moved into a recently renovated Flynn Elementary School shortly before Christmas.
A couple weeks earlier, someone else began arriving at the Burlington school: some unwanted visitors at night.
"It is very sad," Collins said.
Vandals broke windows and tagged most of the walls in back of the school near the playground.
"We have over 300 kids who come every day and they have to look at the vandalism," Collins said.
This is not the first time the school has been hit recently. They've already removed graffiti from other times they were targeted.
"Over the past month or so there have been about five vandalisms," Burlington Police Cpl. Brian DiFranco said.
Police suspect the same vandals are doing it. Their tags read L.O.T. or Paradox and "live in the shadows." But investigators may have just gotten a break to bring the vandals out of the shadows.
"Basically we just want this to stop," DiFranco said.
Recently installed security cameras at the school just caught them in the act. One of the vandals wore a skeleton mask and a white bandana around his leg when he marked up the school. His partner in crime was dressed in a gray hoodie. Both had backpacks.
"We can't have any more damage. We are looking for our kids to have a safe and clean place to play and go to school," DiFranco said.
Students describe the crimes as sad. But they're also costly. Taxpayers may have to shell out thousands for fixes.
"This building belongs to our kids and our community, so the victims are right here in the classrooms," Collins said.
If you recognize the vandals, call police. And they also want you to keep an eye out for those tags popping up elsewhere. If you see someone using those tags, you should report that, too.
