HARRISBURG, Pa. (CBS) — Opening statements are expected Tuesday in the trial of former Penn State President Graham Spanier — accused in an alleged cover-up of the Jerry Sandusky sex abuse scandal.

Seven women and five men were impaneled in an unusual jury selection process. In open court, the judge asked more than 130 prospective jurors general questions about potential conflicts, including whether or not they might be influenced by their feelings about Penn State – good or bad. They responded by standing up. But then, one by one, prospective jurors were interviewed and chosen in the judge’s chambers, away from public view.
