The two men charged with shooting two Chinese graduate students near the University of Southern California have pleaded not guilty.

The long-delayed arraignment of 20-year-old Bryan Barnes and 19-year-old Javier Bolden has cleared the way for further proceedings in the murder case.

The men are charged with the April 11th shooting of engineering students Qu Ming and Wu Ying in a car a mile from campus. Barnes and Bolden are also charged with attempted murder in unrelated attacks. Prosecutors believe the killings took place during a robbery.
