In his audio statement Monday, Sandusky said, "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."
He accused the judge of bringing the case to trial too quickly, the victims of conspiring together, and the attorneys of trying to make money in future civil suits -- which an attorney for Victim No. 5 called "preposterous."
It has been nearly a year since the Penn State scandal erupted, leading to the firing of iconic head football coach Joe Paterno and the ouster of the university's longtime president, Graham Spanier.
Jurors determined in June that Sandusky, who retired from Penn State in 1999, used his access to university facilities and his foundation for under-privileged youth to sexually abuse the boys.
On June 22, Sandusky was convicted on 45 counts of child sex abuse, ranging from corruption of minors to involuntary deviate sexual intercourse, which were laid out in graphic testimony by his accusers over the course of the less-than-two-week trial.
During the trial, which garnered national attention and cast a shadow on Penn State's heralded football program, the 23-year-old Victim No. 4 testified that he was only 13 when Sandusky sexually abused him in a university shower.
That account is separate from a 2001 incident that Mike McQueary, a former Penn State assistant football coach, testified about, saying he saw the former coach pressed up against the back of a boy in the shower room of the Lasch Football Building.
McQueary filed a whistle-blower lawsuit last week against the university, according to a court document from Centre County, Pennsylvania.
Less than a month after Sandusky's conviction, former FBI Director Louis Freeh released his university-funded report that blamed Paterno, Spanier, suspended Athletic Director Tim Curley and ex-Vice President Gary Schultz for taking part in a cover-up to avoid bad publicity.
Freeh also said Paterno could have stopped the attacks had he done more, though neither McQueary, Sandusky nor Paterno -- who died in January -- were interviewed by his investigators.
Attorneys for Spanier blasted the review, calling it a "blundering, indefensible indictment" and "a flat-out distortion of facts" that was "infused with bias and innuendo."
In July, the NCAA imposed sanctions against Penn State, including a $60 million fine, scholarship reductions, the vacating of 112 wins of the football team, five years' probation and a bowl ban for four years.
After the sentencing decision was announced, the university's president released a statement.
"Our thoughts today, as they have been for the last year, go out to the victims of Jerry Sandusky's abuse," Penn State President Rodney Erickson said. "While today's sentence cannot erase what has happened, hopefully it will provide comfort to those affected by these horrible events and help them continue down the road to recovery."
