Jerry Sandusky released an audio statement on Penn State radio on the eve of his Tuesday sentencing hearing, reinforcing his innocence and attacking the credibility of his accusers.

Sandusky lawyer Joe Amendola, speaking Monday in Bellefonte, Pa., before Sandusky went on psucomradio.com, said ‘‘it’s as certain as certain can be’’ that the former Penn State assistant football coach will speak to Judge John Cleland and assert his innocence before he is sentenced on 45 counts of child sexual abuse.

“They could take away my life, they could make me out as a monster, they could treat me as a monster, but they can’t take away my heart,” said Sandusky. “In my heart, I know I did not do these alleged disgusting acts.”

Amendola said he did not expect others to speak on Sandusky’s behalf, although lead prosecutor Joe McGettigan said as many as a half-dozen victims are expected to be heard.

Given the number of charges and the nature of his crimes, the 68-year-old faces the likelihood of state prison for the rest of his life. Sandusky was convicted in June of abusing 10 boys over 15 years, including some attacks inside Penn State athletic facilities.

‘‘The important thing for us is, it starts the appellate process,’’ Amendola said.

One element of the appeal is expected to be a claim that the defense did not have time to adequately prepare for trial. Sandusky was charged in November.

“They won,” said Sandusky. “I’ve wondered what they really won: Attention, financial gain, prestige . . . will all be temporary.

“Before you blame me, as others have, look at everything and everybody. Look at the preparation for the trial and the trial. Compare it to others.”
