A young man from Santa Rosa Beach, an affluent coastal area in Florida’s 30A region, found himself behind bars over the weekend. Authorities allege he made alarming threats about a school shooting on TikTok, which triggered a swift investigation involving both local deputies and the FBI.

The Walton County Sheriff’s Office was alerted by the FBI on Saturday about a potential online threat. The threat involved a TikTok account where someone had reportedly livestreamed violent remarks about a school shooting. These comments were quickly flagged and removed from the platform due to their dangerous implications.

Through cooperation with federal agents, deputies traced the account back to Ethan Charles Ladner, a 20-year-old resident of Santa Rosa Beach. Upon contacting Ladner, he acknowledged owning the TikTok account. According to the sheriff’s office, Ladner confessed to posting the threatening messages, claiming his intention was to provoke online reactions.

Ladner now faces charges of making electronic threats of a mass shooting, which is considered a felony under Florida law.

According to booking information from the Walton County Jail, he was arrested on Sunday and processed on the single felony charge.

In a statement, the sheriff’s office emphasized that threats of school violence, whether intended seriously or as “jokes,” are investigated as credible until proven otherwise.

“Let us be clear. There is no such thing as a ‘joke’ when it comes to threats of violence toward our schools,” the agency said. “These investigations mobilize extensive law-enforcement resources and carry serious legal consequences.”

Officials said the timing of the threat heightened concern, as students in Walton County public schools returned from Thanksgiving break on Monday.

The sheriff’s office said deputies continue to work closely with local school officials and federal partners “to ensure a safe environment for both students and staff.” Fox News Digital has reached out to the Walton County Sheriff’s Office and the FBI for additional details.

The agency urged parents to speak with their children about the seriousness of posting threats or violent remarks online, noting that such behavior can lead to criminal charges, school discipline, and “long-term consequences that follow someone for life.”

“Every threat is treated as credible,” the sheriff’s office said. “We take every threat, online or otherwise, seriously and will act swiftly.”

The sheriff’s office added it remains committed to protecting school communities and thanked residents for reporting concerning activity.

“We are grateful for a community that looks out for one another,” they said.
