More details of an elite prep school's campus tradition of sexual conquest are emerging as former classmates testify at a graduate's rape trial in New Hampshire.

Attorneys for Owen Labrie of Tunbridge, Vermont, say he had consensual sexual contact with a 15-year-old girl days before graduating from St. Paul's School in Concord last year. Prosecutors allege he raped her as part of a tradition called "Senior Salute."

Boston.com reports (http://bit.ly/1LwhiyN) that students who testified Monday said "Senior Salute" could involve anything from kissing to sex. Some said Labrie and his roommate were in a "Senior Salute" contest, though the roommate denied that account. One student said Labrie initially smirked and said he didn't have sex with the girl but later said he did.

Labrie is expected to testify this week.
