Jerry Sandusky trial shifts to former Penn State coach's defense with prosecutors likely to rest case

Sandusky, the former Penn State coach, is charged with 51 counts of child sexual abuse involving 10 boys over a period of 15 years. Monday, the prosecution withdrew one count (Count 33 - Victim #7, unlawful contact with a minor) because the law related to the charge did not go into effect until a few years after the alleged crime.

The defense is expected to argue that Sandusky's behavior was not that of a sexual predator, but rather of a man attempting to draw attention to himself by his activities, CBS News chief investigative correspondent Armen Keteyian reported.

The psychologist is expected to testify early on in the defense's case.
