Freed from custody while awaiting sentencing on federal fraud charges, Xue Heu of Modesto, Calif., in April bilked $ 6,000 from an unsuspecting homeowner in need of a loan modification, authorities say. A few weeks later, he scammed $ 3,500 from a high school buddy by selling him counterfeit fantasy game trading cards, and invoked Donald Trump in an effort to bleed more money.
