Are you sure it was Nebraska?
There was a prosecutor who went missing but he was in Pennsylvania. Ray Gricar was the district attorney for Centre County, Pennsylvania and went missing in 2005.
In 1998, after one victim's mother contacted LE about Jerry Sandusky, LE had a taped conversation in which Sandusky affirmed that the mother was right to be angry with him. LE was ready to go after him at the time but Ray Gricar declined to do so.
Personally, I doubt Sandusky was part of a ring. He had plenty of access to potential victims and plenty to use to lure them, so what would he gain from being part of a ring? Plus, from everything I've read about him, Sandusky seems to me to be one of those who was in love with his victims. Or maybe it would be more accurate to say he was emotionally fixated on them.
If I am correct, Sandusky would be highly unlikely to participate in "passing around" victims.
