BELLEFONTE, Pa. (AP) -- One of Jerry Sandusky's alleged victims says he was sexually abused as a young teenager on campus and then in hotel saunas, starting with showers that turned into oral sex.

Prosecutors call the witness Victim No. 4. The man, now 28, spoke calmly and firmly when questioned by lead prosecutor Joseph McGettigan III.

Sandusky sat still during the testimony Monday as the man explained that he began showering with the former Penn State assistant football coach in 1997.

He says what began as "soap battles" escalated into inappropriate touching and oral sex.

The man says he met Sandusky through The Second Mile charity that the assistant coach founded. He says that he received letters from Sandusky, too, including one on Penn State letterhead.
