Hanjuan Jin enters the federal courthouse Wednesday, Aug. 29, 2012, in Chicago, before being sentenced to four years in prison for stealing trade secrets from Motorola. Jin, who worked as a software engineer for Motorola Inc. for nine years, was stopped during a random security search at Chicago's O'Hare International Airport on Feb. 28, 2007, before she could board a flight to China. Prosecutors say she was carrying $31,000 and hundreds of confidential Motorola documents, many stored on a laptop, four external hard drives, thumb drives and other devices.(AP Photo/M.
