Jerry Sandusky is driven by authorities from Centre County Jail to his State College, Pa., home after spending the night in jail, Thursday, Dec. 8, 2011. Sandusky was charged Wednesday with additional counts of sexual abuse of minors. The former Penn Setate assistant football coach was released after posting bail on new charges that he sexually abused two additional boys, including one who said Sandusky assaulted him in his basement while his cries for help went unheeded.

STATE COLLEGE, Pa. — Accusations of child sex abuse by former Penn State assistant football coach Jerry Sandusky are also raising questions about whether his wife knew about his alleged pattern of preying on boys.

One accuser told the grand jury that Dottie Sandusky was home when he screamed for help while her husband sexually attacked him in a basement bedroom.

She calls the accusation false, and says her husband is innocent.

Lawyers not involved in the case say the claim doesn't prove Dottie Sandusky did anything wrong.

Prosecutors could ask a court to compel her to testify, but lawyers say she's unlikely to incriminate Sandusky, and in any case prosecutors may feel they don't need her testimony to prove their case.

Still, lawyers say the Sanduskys are almost certainly facing expensive civil lawsuits.
