Two local high school students face charges after making threatening other students on social media.

A 15-year-old Fort Walton Beach High School student was charged Wednesday with threatening to kill or injure someone, which is a felony.

Brent Robeen, who lives in Shalimar allegedly posted a video to SnapChat in which he took a photo of himself with what appeared to be an AK-47. The words, "Don't come to skool tomorrow" was written across the screen, according to his arrest report from the Okaloosa County Sheriff's Office.

Also on Wednesday, a Navarre High School student warned others not to go to school Friday, adding that he would shoot up the school. The Santa Rosa County Sheriff's Office investigated the threat and said the student faces felony charges, but had not been arrested as of Thursday evening. 

A screenshot of the threats posted on a private Facebook group by a concerned parent who called authorities show the Navarre student warning the recipient, "I will (expletive) shoot up the school if you don't respond."

"I'm going to shoot (sic) yo ugly (expletive) first," read another.

According to Robeen's arrest report, he told a deputy that he had posted the video and that it was just a joke. He said he had no intentions of hurting himself or anyone else.

"No one ever takes these things serious," he said, according to the arrest report.

The deputy noted that the weapon, which was a toy Airsoft gun, was "very realistic" looking.

Sheriff's deputies interviewed the victim at school Thursday. She said that after she saw the video she showed it to her mother, who told her they needed to report it. The student emailed the video to the Fort Walton Beach High School principal and to the school resource officer.

The student told the deputy that she was scared for the safety of herself and her friends and that she hadn't wanted to go to school after watching the threatening video.

In the Santa Rosa county case, investigators determined the student who wrote the threats did so under another student's name by creating a fictitious account. That student was confronted with the evidence collected during the investigation.

"Threats over social media are taken very seriously," Sheriff's Office spokesman Rich Aloy said in a press release. "Unfortunately for those who decide to commit these crimes, they leave an obvious digital trail for investigators to follow. Along with criminal charges, other consequences can include suspension and alternate schooling."

Another Navarre High student was suspended late last month for threatening fellow students.
