BELLEFONTE, Pa. — The clearest portrait of Jerry Sandusky to emerge during the trial that ended Friday night with his conviction may have been the one hardly anybody saw.

It was lunchtime Monday, the defense was beginning to present its case, and the proceedings had broken for lunch. The jury had been led out of the courtroom. The attorneys were gone. All but a handful of the roughly 180 spectators and reporters had departed.

That’s when a few stragglers still in the courthouse annex, watching the closed-circuit TV feed from the courtroom, noticed a curious scene.
