SEMINOLE COUNTY, Fla. – While his office was closed during the early stages of the COVID-19 pandemic, former Seminole County Tax Collector Joel Greenberg was at the location “practicing” how to make fake concealed weapon permits, according to federal prosecutors.The new allegation comes as evidence continues to mount against Greenberg, who resigned in June after he was indicted on federal stalking charges.According to the notice of intent filed Monday, Greenberg was committing criminal acts “until his last day in office.”Prosecutors said that earlier this year when the part of the office that issues concealed permits was closed, Greenberg called one of his employees for help on how to fix the printer that produces the permits.
