The Indiana Attorney General's Office on Thursday filed a complaint against Southport Mayor Rob Thoman, alleging fraud and material deception in his dental license applications spanning two decades.Thoman, who has an office at 7007 U.S. 31 S. in Indianapolis, failed to disclose on his 1987 application that he had pleaded no contest to felony embezzlement charges relating to school funds in 1981, the AG's office alleged. At that time, Thoman was student body president at Colorado State University.The complaint filed with the Board of Dentistry also claims that on a question asking about military service, Thoman answered "not applicable."The state said Thoman served in the U.S. Army as an operating room specialist from 1977 to 1980 and that he "separated from the service under other than honorable conditions; administrative discharge conduct triable by court martial."The AG's office claimed that Thoman also failed to disclose the Colorado incident when he filled out his application in 2003 to be able to administer anesthesia and sedation."Even if it happened a long time ago, it is something we would have expected for him to answer honestly," said Deputy Attorney General Abby Kuzma.The Board of Dentistry was asked to consider sanctions against Thoman. He could face censure, a letter of reprimand, suspension or a revocation of his medical license, along with a maximum fine of $2,000. A hearing date was not immediately set.Thoman told 6News' Rafael Sanchez that he was unaware of the complaint and will have his attorneys review it. Thoman's term as mayor has been controversial, including several disputes with councilors and other city officials.
