Vandals have targeted a marquee outside Stuckey Elementary School three times in the past month, according to CCSD Police.
Police said the latest incident happened Thursday night along with two other attacks in the past three weeks.
"I noticed there were rocks thrown into the sign," said Sharon Brown who lives next to the school.
Brown said she saw the sign the first time is was destroyed by graffiti.
"There was graffiti on the sign, then I noticed the next day it was washed off and then the next day something was on it again," Brown said.
Parents on the Nextdoor app said the marquee was funded by the Stuckey Parent and Teacher association and took the organization years to raise the money.
Retired Metro Lt. and 13 Action News Crime and Safety Expert Randy Sutton said vandals are more common in the summer when kids are out of school and unsupervised.
"If they have nothing to do, they find something to do and you have to remember there are a lot of unsupervised juveniles roaming around the valley," Sutton said.
CCSD Police said they are looking at surveillance video from the school to find the suspects.
