WESTMINSTER (CBSLA.com) — Former Buena Park Mayor Sangjin Miller Oh was sentenced Wednesday to six months in jail and three years probation for using a fake name and other false information on DMV documents to avoid paying child support.

Oh, who was a member of the City Council since 2010, stepped down from his post as mayor following his conviction on May 30 of five felony counts of perjury by declaration.

Orange County Superior Court Judge John Adams also ordered Oh to perform 200 hours of community service.

The 50-year-old former elected official must surrender Jan. 9 to begin serving his jail time. If Oh violates any terms of his probation, he will be sent to prison for three years.

Oh, a real estate developer and father of two girls, told an undercover investigator in a recorded conversation that he paid someone $300 to get him a fraudulent driver’s license he could use to register vehicles and hide assets, Deputy District Attorney John Christl said.

Oh used his Roman Catholic confirmation name, Robert, and his lunar birth date on the license application, without disclosing that he had a license under another name, prosecutors said.

Another time, Oh did not disclose that his license had been suspended. On four other occasions, he used the fraudulently-obtained license to register vehicles with the DMV, according to prosecutors.

When campaigning for office in 2010, some forms, including his voter registration, contained conflicting birth dates and other inconsistencies, Christl said. The crimes were committed between Sept. 23, 2004 and July 20, 2009.
