I don't know, what I saw on ESPN was that Joe, when learning about the guy and what he did, reported it to AD. So where does his reporting it to school officials vs the cops cause him to lose his job? Remember, this guy's been in the same job forever and to him, college officials would be his typical direct reporting for any problems.
Of course any guy in their 80's should know that cops come first and college officials can't actually solve anything.....
