Melissa King, belatedly, has admitted to wrongdoing. But she still insists she's small-time. King, former benefits administrator for Local 147 of the Laborers International Union of North America, "the Sandhogs," pleaded guilty in Manhattan federal court on October 21 to embezzling union funds and filing false personal income tax returns. Though prosecutors have put her total take at more than $40 million, King believes that's inflated. "I plead guilty, but I don't plead guilty to millions of dollars," she told U.S. District Judge John Koeltl. Evidence, however, reveals a woman possessed of a limitless desire for material extravagance at the expense of the roughly 1,000-member New York City underground construction union. The exact total of the thefts will be determined later. She faces a maximum eight-year prison sentence in February.
