According to the Volusia County Sheriff’s Office, 15-year-old Adam Guzzetti was charged with a felony after authorities learned he threatened to shoot and kill people at his school, Seabreeze High School in Daytona Beach.

Using the username FalconWarrior920 on the gaming platform Discord, deputies said Guzzetti on Thursday used a fake name and stated “I Dalton Barnhart vow to bring my fathers (sic) m15 to school and kill 7 people at minimum.”

Another user alerted the FBI to the threat, which was then passed on to the sheriff’s office. Members of the FBI Joint Terrorism Task Force were able to track the FalconWarrior920 IP address to an address in Holly Hills, where Guzzetti lives with his mother, Amethy Organ, according to an arrest report.

About 1 a.m., Task Force members went to the house where Guzzetti told special agents he uses the name FalconWarrior920 and made the threats under a false name as a joke. Organ said there was a gun in the house, but that Guzzetti didn’t have access to it.

“Joke or not, these types of comments are felonies under the law,” the sheriff’s office wrote in a Facebook post. “After the mass violence we’ve seen in Florida and across the country, law enforcement officers have a responsibility to investigate and charge those who choose to make these types of threatening statements.”

Deputies arrested Guzzetti the next morning. Body camera footage released by the sheriff’s office show him again admitting to making the threats, while Organ tells deputies there is a gun in the home.

At least five Floridians have been arrested in connection with mass shooting threats in the two weeks since gunmen in El Paso and Dayton killed a combined 31 people. The El Paso and Dayton shootings reignited gun control debates across the country, including talks over controversial ‘red flag’ laws designed to allow authorities to confiscate guns from individuals deemed to be a threat.

Echoing the El Paso Walmart shooting, three of the arrests came after threats made to Florida Walmarts.

Wayne Lee Padgett called a Gibsonton Walmart on Aug. 3 and threatened to “shoot up” the store, according to law enforcement officials. A week later, Winter Park man Richard Clayton was arrested after writing “3 more days of probation left then I get my AR-15 back. Don’t go to Walmart next week," in a Facebook post, authorities said. In Clearwater, 33-year-old Anthony Reed was arrested Aug. 9 after he told a Walmart employee he’d come back with a gun if the remote-control car he was buying didn’t work, according to authorities.

Friday, the same day Guzzetti was arrested, Volusia County deputies also arrested 25-year-old Tristan Wix on charges he threatened to kill 100 people and had a rifle with 400 rounds of ammunition in his home.

Deputies told Organ that Guzzetti would be held in a juvenile detention for “several days.” He was charged with a second-degree felony.
