I have a slightly different theory about why RG did not prosecute in 1998, and it also ties in to how his disappearance could be connected to the Sandusky investigation. My theory is that the high-ups at Penn State persuaded RG not to prosecute in exchange for Sandusky's retirement, which happened in 1999. Sandusky's retirement was q surprise to many when announced. To further explain my theory, perhaps RG was convinced, against his better judgment, that retirement of Sandusky, and reporting of his "activities" to The Second Mile would be enough to stop the abuse from happening again. So, reluctantly, RG agrees-after all, the higher-ups convince him it's best for the community, the school, etc to avoid such a scandal.
Fast forward to 2002and 2005. RG is once again informed of additional incidents, though exactly how I am not sure. Maybe a parent, or even someone connected with The Second Mile who knew what the university reported to them about Sandusky in 1998. Upon learning of additional abuse cases, RG is deeply
disturbed. He decides to reopen an investigation on Sandusky, and notifies those high-ups of his intentions. He tells them he cannot stick to his agreement now that continuing abuses have come to light. And, that was the beginning of
his end. Of course, all of this is pure speculation, and MOO. But, it occurred to me that detectives investigating RG's disappearance would look at cases he prosecuted, but would most likely not be focused on cases he did NOT
prosecute. Of course, the info that he was about to re-open an investigation against Sandusky may have been in the hard drive which was utterly destroyed. JMO
