SANTA ANA – Orange County officials have begun an audit of the Sheriff’s Department after Sheriff Michael Carona was indicted last week on corruption charges. The county’s audit oversight committee met Wednesday and decided to look at 21 department accounts, Supervisor John Moorlach said. Auditors also will examine Carona’s travel expenses. Carona said earlier this week he will take a two-month leave of absence to fight federal charges that he and others took nearly $700,000 in bribes and kickbacks. “There is no indication by reading the indictment or through other sources that there’s any nefarious activity in the Sheriff’s Department,” said county Auditor-Controller David Sundstrom, who added the probe was precautionary. Carona, 52, has pleaded not guilty to a count of conspiracy, four counts of mail fraud and two counts of witness tampering after a federal indictment was unsealed last week. His wife, Deborah Carona, pleaded not guilty to one count of conspiracy and Debra Hoffman, a woman identified in court papers as his mistress, pleaded not guilty to one count of conspiracy, four counts of mail fraud and three counts of bankruptcy fraud. Moorlach also suggested that Carona should be prohibited from using a county credit card while he’s on leave. Carona’s spokesman, Michael Schroeder, said the sheriff did not have a card in his possession. Carona will be paid $33,166 during his leave.
