Honestly, I'm not exactly certain what this means. However, news from the courtroom stated, quote, "The jury will be be back in the courtroom in 10 minutes to deal with a supplemental charge."
Make what you will of that.
Update: Fox News is reporting that the jury is seeking clarification on testimony that a janitor gave. The janitor stated that he heard that a fellow employee had witnessed Sandusky had raped a child. This, however, is hearsay because he did not witness it himself.
