BELLEFONTE, Pa. (AP) -- A lawyer for an adopted son of Jerry Sandusky says the man has told authorities the former Penn State assistant football coach abused him.

Matt Sandusky is one of Jerry Sandusky's six adopted children.

His lawyer issued a statement Thursday naming Matt Sandusky and saying that the 33-year-old had been prepared to testify on behalf of prosecutors at his father's sex abuse trial.

The statement says Matt Sandusky is "a victim of Jerry Sandusky's abuse," but doesn't go into specifics.

The statement came after jurors began deliberating 48 charges against the ex-coach. Prosecutors say Sandusky met the 10 sex-abuse victims through his charity.

Lawyers for Matt and Jerry Sandusky and prosecutors did not immediately respond to requests for comment.

Matt Sandusky's lawyer says his client met with investigators very recently.
