DALLAS -- It appeared to be business as usual inside South Oak Cliff High School on Thursday, but outside the campus, it was a different story.

"It’s red paint all up and down our streets,” said neighbor Chris Brewster.

A reddish dye-like substance covered part of the campus grounds. It also stained nearby streets.

"I thought it was probably like a high school prank," said Brewster.

Neighbors say they noticed the paint or dye covering the school’s parking lot on Wednesday. Many wondered what it is and how it got there.

"Our school goes through enough,” said neighbor Quinton Willis. “You know, it’s all kinds of problems in there.”

The mysterious red paint is pretty much everywhere you look nearby. There’s even a trail of the mess staining streets from I-35 at Kiest, and spreads all the way to South Oak Cliff’s campus.

"You’ve got the Marsalis neighborhood. You’ve got the other side’s neighborhood. You’ve got the cars in the parking lot. You’ve got people shoes. You’ve got all kinds of stuff," Willis explained.

Environmental workers from the City of Dallas and Dallas Independent School District are analyzing the peculiar red paint problem. They are trying to come up with an action plan for cleaning things up.

The school does have surveillance cameras, but they did not capture any images from the area.

"We don’t know if it’s vandalism. We don’t know if this was intentional or not. So, we’re just wanting to find out more information," said Dallas ISD spokeswoman Robyn Harris.

Neighbors want the person behind the problem to know it’s a frustrating eyesore.

“If you messed it up, come over here and help us clean it up!” said Brewster.

Neighbors say they do not want any more problems painting bad images of their community.

This remains an ongoing investigation. Dallas ISD says a reward is being offered through Crime Stoppers for any tips leading to the identity of the individuals responsible for dumping the red dye.
