Three principals of a company that imported paving stones from Australia were charged with conspiracy, securities fraud, and money laundering in an indictment unsealed today in federal court in Central Islip, New York. The charges against Eric Aronson, Vincent Buonauro, and Fredric Aaron arose from their solicitation of investor money for, and their operation of, Permapave Industries and Permapave USA (“Permapave”). Permapave marketed porous paving stones in the United States that were manufactured in Australia.
