ABC News' Alex Perez reports:

Zachary Tomaselli's allegations of sex abuse turned the world of college basketball upside down.

Now, the 23-year-old says he made the whole story up.

"It was just a game that I decided to see how far I could push it and I was able to push it a lot further than I could ever have imagined," Tomaselli told ABC affiliate WMTW.

Tomaselli accused Syracuse assistant basketball coach Bernie Fine of sexually abusing him when he was 13 at a hotel in Pittsburgh.

Fine, who has since been fired, was accused of molesting four boys, but because of the statute of limitations, Tomaselli was the only one who could pursue charges.

Tomaselli, who now admits never even meeting Fine,  says his lies snowballed, "One lie lead to another…I just didn't have a lot of care that I should have had as a human being."

He also compares himself to a serial killer.

"Serial killers they all want to basically show everybody, hey-look what I've done. They want to be caught."

Although the US Attorney's Office in Syracuse is still investigating, legal analyst Sunny Hostin believes this could spell the end of the legal case against Fine.

"When you're prosecuting a case, it's not about what happened, it's about what can you prove, and now when you have the alleged victim recanting the story, now you don't know what happened, and you certainly can't prove it," she said.

Tomaselli's legal troubles however are growing.

This week he was sentenced to 3 years and 3 months in prison for sexually abusing a 13-year-old boy in 2009.
