CHICAGO (Reuters) - A former software engineer at Motorola who was stopped at O'Hare International Airport carrying thousands of the cellphone company's proprietary documents was found guilty of stealing trade secrets on Wednesday, but cleared of economic espionage for China.

The defendant, Hanjuan Jin, was charged with illegally possessing thousands of Motorola's trade secrets on her computer, several external hard drives and recordable compact discs as she attempted to board a flight to Beijing on a one-way ticket.
