Lot of speculation; no evidence.
When the indictment broke, I actually had someone who had know him asking if he had been paid off. The actual evidence, at least so far, is against it. Not a lack of evidence, but a little bit of evidence against it.
Then there is the group that says he found something new and got murdered by someone involved. LE has said that he wasn't doing anything with Sandusky when he disappeared.
There is something strange. In 1998, the DA's Office had an ADA that handled abuse cases, Arnold. She was involved initially, but Gricar took the case away from her; it was characterized in some of the court filings as "extensive disagreements" over the handling of the case.
There was a meeting between Gricar, the two officers involved (from different departments), another ADA, and Assistant Coach Fran Ganther, in the football building on 10/13/98, but know one seems to be saying what it was about.
