His sex abuse allegations brought the fall of a once-revered college football coach and were at the heart of one of the most infamous child molestation cases in history. Now the young man identified for years only as Victim 1 in the Jerry Sandusky case says he doesn't want to be known as an anonymous victim anymore.

Aaron Fisher sat down with Chris Cuomo for an exclusive interview airing on "20/20? tomorrow, in conjunction with the release of Fisher's new book detailing his struggle to have his allegations taken seriously: " Silent No More: Victim 1's Fight for Justice Against Jerry Sandusky."

"Victim means, people feel sympathy for you, I don't want that," he told Cuomo. "I would rather be somebody who did something good, like a hero or something."

Fisher explained how Sandusky, a respected former coach at Penn State University, went from an "all-natural father figure" to a predator stalking his prey, pulling him out of class at his high school and once even chasing him home from school in his car as the teen desperately tried to outrun him.

Fisher met Sandusky at age 11. He had been invited, in the summer of 2005, to attend the summer camp run by Sandusky and Second Mile, a highly respected charity, on the campus of Penn State University. He said Sandusky singled him out, telling the boy - who came from a struggling family and had no father at home - that he had athletic potential and taking him to sporting events.

Then Sandusky began inviting Victim 1 to spend weekends at his home. That was where, Victim 1 said, Sandusky took him to the basement and the fun and games turned to horror.

When Fisher reached high school, he had even more exposure to Sandusky - the ex-Penn State coach was also a volunteer high school coach. Sandusky regularly pulled him out of his classes; Fisher did all he could to avoid the predator, sometimes hiding in school bathrooms.

"He once followed my bus home from school. He told me to get in the car. I took off running. He drove on the opposite of the street, onto oncoming traffic to catch up with me, and then I ran up an alley, he went to my house and parked out front," Fisher told Chris Cuomo. "Yeah, it was that bad."
