Two Oregon State University students face charges.  The two are accused of spray-painting stenciled pictures of "storm trooper" characters from the "Star Wars" films throughout the Corvallis campus.  Authorities say John Zaikoski, 19, and Kamela Hasselman, 18, were arrested on suspicion of second-degree criminal mischief. 

Police say at least 15 areas of the campus were hit by the alleged sci-fi graffiti artists. They were identified after a review of surveillance video.
