BELLEFONTE, Pa. (AP) - The first witness at Jerry Sandusky's child sexual abuse trial says he feels responsible for what happened to other alleged victims because he didn't come forward earlier.

The 28-year-old man said Monday he was reluctant to cooperate with the sweeping investigation into the allegations against the former Penn State assistant football coach.

Under cross-examination by defense lawyer Joseph Amendola, the man said: "I feel if I just said something back then ... I feel responsible for what happened to other victims."

The man tells jurors that Sandusky gave him several gifts, including a snowboard and a copy of Sports Illustrated magazine autographed by linebacker LaVar Arrington.

Sandusky faces 52 criminal counts that he sexually abused 10 boys over 15 years. He has denied the allegations.
