When Wei Sun, a 48-year-old engineer at Raytheon Missile Systems, left for an overseas trip last year, he told the company he planned to bring his company-issued HP EliteBook 840 laptop along.
Sun, a Chinese-born American citizen, had been working at Raytheon, the fourth-largest US defense contractor, for a decade. He held a secret-level security clearance and worked on highly sensitive missile programs used by the US military.
Since Sun’s computer contained large amounts of restricted data, Raytheon officials told him that taking it abroad would not only be a violation of company policy, but a serious violation of federal law, as well.
When Sun returned to the United States a week later, he told Raytheon security officials that he had only visited Singapore and the Philippines during his travels. But inconsistent stories about his itinerary led Sun to confess that he traveled to China with the laptop.
