(NBC) - On a dramatic day two of the Jerry Sandusky sex abuse trial key prosecution witness Mike McQueary was called in to testify against his Penn State coaching mentor.
McQueary has told authorities he caught Sandusky in a shower with a young boy, but whether he saw a sexual assault or simply assumed it was one, is one of the central questions in the case.
McQueary testified that he heard a sound, caught a glimpse of something, but didn't report it immediately to authorities.
Prior to McQueary taking the stand, the day began with a distraught 18-year-old known as Victim #1 describing what he said was his first sexual encounter with Sandusky.
"I froze," he said. "My mind was telling me to move but I couldn't do it. I couldn't move."
He wasn't yet 13, and testified that Sandusky's seemingly innocent touching escalated into repeated sexual contact.
The witness was the first to speak out and bring Sandusky to the attention of authorities.
During defense cross-examination the witness acknowledged he told different versions of his story to a grand jury.
Under persistent questioning he broke down again, admitting that he didn't tell the truth because he was afraid and ashamed.
A social worker verified the young man's account, saying Sandusky admitted to having various forms of physical contact but said there wasn't any sexual intent.
Like the previous accuser, the second witness acknowledged that he has a civil lawyer, but denied he once said this case was going to make him rich.
The witness' grandfather testified that Sandusky demanded to know the boys plans one summer so the coach could plan his own calendar.
