She’s been a constant, if silent, presence by Jerry Sandusky’s side.

Dottie Sandusky had not spoken publicly in more than six months until taking the witness stand Tuesday in her husband’s child sexual abuse trial. She says he never had inappropriate contact with boys.

Critics say Sandusky’s wife stood quietly by while the once-revered Penn State assistant football coach sexually abused boys in the basement of their home.

But experts in child sexual abuse say offenders are typically very good at concealing their proclivities, even from those closest to them.

Jerry Sandusky also denies all the charges.
