@foxnews: College fraternity culture collides with an alleged cocaine trafficking ring at Penn State, where investigators say some pledges were forced to help as part of an alleged indoctrination. Authorities are now identifying more alleged participants while tracking cocaine packaging at off-campus houses and tracing the drug's movement between the university, New York, and Philadelphia. Penn State says it is "horrified" by the allegations. Delta Upsilon has been suspended, while Sigma Chi is not recognized by the university.
