A Florida middle school student was arrested and charged as an adult earlier this year after allegedly creating his own homemade guns and explosives in preparation for a robbery, authorities said this week. The alleged texts between the boys, who attended Switzerland Point Middle School, contained information about building a shotgun and musket and obtaining zip ties, according to the arrest report. Authorities said charging Davis, who they claim demonstrated an intense interest in school shooters, could have prevented a "tragedy" at the middle school and the broader community. Davis' friend, with whom he was texting about the alleged robbery, spent 21 days in the Florida Department of Juvenile Justice before being released, the sheriff said. St. Johns County School District Deputy Superintendent Paul Abbatinozzi clarified there was never a direct threat to Switzerland Point Middle School.
