School Resource Deputy Patrick Diaz, along with the principal of Turkey Creek Middle School in Plant City, had been monitoring students in the parent pick-up line after school when Deputy Diaz spotted a man walking alongside a road bordering the school, according to a news release from the Hillsborough County Sheriff's Office. The man, later identified as Bruce Chalmers Hicks, was pushing a "dolly" which had an old plastic toy car attached to it. As the man walked past the student line, Deputy Diaz spotted something else -- a possible small firearm holstered on his left hip, the release stated. Deputy Diaz then called out to Hicks, who while turning around, reportedly stepped on the grass of the school's property. Hicks allegedly told Deputy Diaz that there was a $250 fine for every 15-minutes of unlawful detention, as he is a sovereign citizen and is not subject to the laws of the United States or Hillsborough County. When Deputy Diaz then asked Hicks if he was carrying a firearm, Hicks answered that he was and repeated that he was not subject to laws, according to the Sheriff's Office. Deputy Diaz then seized Hicks' gun -- a Davis Industries two shot thirty-two caliber handgun -- which had two live cartridges in the barrels, deputies said. Deputies also said the 46-year-old Plant City man has an extensive criminal history, including Lewd Or Lascivious Molestation of Victims Under 18. Records show this is Hicks 12th booking in the Hillsborough County Jail since August 2003.
