A judge found Dongfan "Greg" Chung, 74, guilty in July of six federal counts of economic espionage and other charges for keeping 300,000 pages of sensitive papers in his home. The documents also included information about the fueling system for a booster rocket. Despite Chung's age, prosecutors have requested a 20-year sentence, in part to send a message to other would-be spies.
During the non-jury trial, Chung's lawyers argued that he may have violated Boeing policy by bringing the papers home, but he didn't break any laws by doing so, and the U.S. government couldn't prove he had given secret information to China. (Source: AP, Feb8, 2010).
