The former mayor of Buena Park was sentenced Wednesday to six months in jail for falsifying state documents in an effort to avoid paying child support, authorities said.
Sangjin Miller Oh was also ordered to serve three years' probation and will be banned from ever holding public office again, said Susan Kang Schroeder, spokeswoman of the Orange County district attorney's office.
"No one is above the law," said Susan Kang Schroeder, chief of staff for the Orange County district attorney's office.
"Honesty is the bare minimum of what you owe to the public."
A jury found Oh guilty in May of five felony counts of perjury by declaration. He was a member of the City Council when he was formally charged.
Between Sept. 23, 2004, and July 20, 2009, prosecutors said, Oh avoided paying his ex-wife child support payments and hid his assets under a false name.
At one point, he applied for a driver's license under the name Robert Oh, and failed to tell authorities that he had previously applied for a driver's license under a different name.
Prosecutors said he also failed to disclose that his license was previously suspended.
He also used a fake driver's license to register vehicles, according to the district attorney's office.
During his 2010 campaign, Oh described himself as a father, husband and longtime businessman.
