Kilgore High School increased security Wednesday after parents were notified that a post on the multimedia messaging app Snapchat threatened a shooting at the campus, interim Superintendent Mike Morrison said.

Morrison said Kilgore ISD contacted Kilgore police, who are investigating the post. The district sent out an “all call” around 11 a.m. informing parents about the threat, he said.

“We increased the police presence at the school, and (police are) still investigating. Hopefully, we can find out who made the threat,” Morrison said. “We’re just mainly trying to keep our teachers and students safe.”

The Snapchat post displays a photo of Kilgore High School with a message that reads, “Y’all don’t show up to Kilgore (High School) today. I’m shooting that b-- — up (for real). I’m tired of y’all making fun of me and it’s time for y’all to pay.”

Assistant Police Chief Roman Roberson said Wednesday afternoon that “there’s no active threat” at Kilgore High School.

“It’s simply a social media post that was made that we’re looking into,” Roberson said. “We can’t attest to the validity of it. We don’t know if it’s credible or not credible. The school’s safe. That’s for sure.”

Former Superintendent Cara Cooke said in April that three full-time school resource officers secure district campuses.

Administrators have not determined if more police will be needed on campus Thursday, Morrison said.
