Florida middle schooler charged as adult after deputies find homemade guns, explosives, and mass-shooter research at his home

A 14-year-old St. Johns County student faces adult charges after sheriff's deputies say they found three homemade firearms, explosive components, and extremist materials in his bedroom, and the sheriff says a robbery plot may have been the least of the danger.

Julian Davis, a student at Switzerland Point Middle School in St. Johns County, Florida, was arrested April 30 after an investigation that began three days earlier with a tip submitted through FortifyFL, the state's anonymous threat-reporting platform created after the 2018 Marjory Stoneman Douglas High School shooting. Deputies and federal investigators conducted multiple searches of Davis's home between April 27 and April 30, Fox News Digital reported.

What they found went well beyond a teenager's mischief. Investigators recovered three homemade firearms, ammunition, suspected explosive components, makeshift handcuffs, a tactical vest bearing alleged white-supremacy drawings, handwritten notes, and a drawing of what appeared to be a Molotov cocktail. They also seized a copy of the manifesto written by Brenton Tarrant, who killed 51 people in shooting attacks on two mosques in Christchurch, New Zealand, in 2019, along with a U.S. Army improvised-munitions handbook and a copy of "The Anarchist Cookbook," a 1971 publication that details how to build weapons and explosives.

Sheriff says Davis studied mass shooters and "wanted to emulate" them

St. Johns County Sheriff Robert Hardwick addressed the case publicly for the first time at a Friday news conference alongside federal investigators. He told reporters there was a "much bigger picture than just a robbery of that individual", a reference to the alleged plot to hold up a person known only as "CJ," whose identity investigators have been unable to determine.

Hardwick described Davis's online activity in blunt terms:

"Davis was using his devices in his home to research things. He had a [fixation] with people that had committed these mass school shootings, people that have gone in and done these mass stabbings. So, he was actually spending a lot of his time on there going through these high-profile cases. And it's something that he actually wanted to emulate."

The sheriff's language left little ambiguity. In his telling, the arrest may have headed off something far worse than a street robbery, a claim that carries enormous weight but rests, so far, on what investigators say they found on the boy's devices and in his room rather than on a specific, documented plan to attack a school or public gathering.

Telegram messages allegedly detailed a plan to build a shotgun and obtain zip ties

Davis and a 13-year-old friend, also a student at Switzerland Point Middle School, had been messaging each other on Telegram about "holding someone at gunpoint" to rob them, according to the arrest report as described by Fox News Digital. Those messages allegedly contained information about building a shotgun and a musket and about obtaining zip ties.

Both boys were charged with conspiracy to commit robbery with a gun. Davis alone faces multiple additional gun and explosive offenses. The specific statutes and number of counts have not been publicly detailed. Prosecutors chose to charge Davis as an adult. His 13-year-old co-conspirator was not charged as an adult; that boy spent 21 days in a Florida Department of Juvenile Justice facility before being released.

Neither boy has been permitted to return to Switzerland Point Middle School. Deputy Superintendent Paul Abbatinozzi clarified that no direct threat was ever made against the school itself, a distinction that matters for the community but does not diminish the severity of what deputies say they pulled out of Davis's home.

Davis sits in county jail on $240,000 bond while his attorney pushes back hard

Davis pleaded not guilty. He is being held at the St. Johns County Jail on $240,000 bond, with an arraignment scheduled for next month. His attorney, Jill Barger, told Fox News Digital that Davis has spent roughly four months "in an empty pod" at the jail and has grown frightened and depressed. Barger accused the state of failing to provide Davis "the resources he needs" and slammed the sheriff's office for publicly announcing the charges, calling it an attempt to "influence jurors ahead of trial."

In a written statement, Barger went further:

"Julian never even thought about harming anyone. The police were reckless and cruel to suggest they prevented a mass casualty event. There is no evidence of this. No writings by Julian, no threats, nothing."

That claim will be tested at trial. But the physical evidence described by investigators, three homemade firearms, explosive components, a mass shooter's manifesto, bomb-making manuals, a tactical vest with extremist markings, is not the kind of material that appears in a 14-year-old's bedroom by accident. Whether Davis ever intended to use those items beyond the alleged robbery is an open question. That he assembled them at all is not.

FortifyFL delivered the tip that started the investigation

The case began when someone submitted a tip through FortifyFL on April 27. The platform was built specifically to catch threats like this one, suspicious behavior by students that might otherwise go unreported until it is too late. In this instance, it worked exactly as designed. Deputies moved within hours, and Davis was in custody three days later.

Hardwick and his deputies deserve credit for acting fast. Federal investigators were brought in quickly, multiple searches were executed in rapid succession, and the 14-year-old was off the street before the end of the month. That is the system functioning. It is also a reminder that the system depends on someone caring enough to make the call.

Several questions remain unanswered. Which federal agencies participated in the searches and the news conference? What specific charges, beyond the broad categories disclosed, does Davis face? And who is "CJ," the alleged robbery target whom investigators still cannot identify?

Those gaps will matter as the case moves toward trial. So will the tension between the sheriff's public assertion that Davis wanted to emulate mass shooters and the defense attorney's flat denial that any evidence of such intent exists. A jury will sort it out. But the inventory of what deputies carried out of that house speaks louder than either side's press conference.

When a 14-year-old is building guns in his bedroom and studying the playbook of a mass killer, the adults who spotted it and acted saved the rest of us from learning what he planned to do next.
