It appears quite likely the prosecution in the Jerry Sandusky case is confident of victory once the jury has finished deliberating. I don't know much about legal things, but this much does seem to be clear. However, just in case the jury acquits, NBC reports more victims are ready to come forward.
A transcript via Deadspin, from a story on Travis Weaver, a 30-year-old Ohio man who's the first alleged victim to speak publicly:
"He is now part of a second group of guys who came forward later, who did testify-he testified before a grand jury, prosecutors have his testimony, he's willing to testify in court. They're holding that group in case they need them, in case they get a not guilty verdict out of this current jury. They could potentially go after federal charges against Jerry Sandusky."
The feds are indeed interested in Sandusky, since he allegedly took boys across state lines on bowl game trips. Weaver alleges he was taken to the 1995 Rose Bowl against Oregon in California.
That's in addition to Matt Sandusky, the Penn State coach's adopted son, who likewise has said he was abused and was prepared to testify.
