Hanjuan Jin, center, leaves the federal courthouse Wednesday, Aug. 29, 2012, in Chicago, after 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. Spencer Green)
