He told Joe Paterno something the next day. (His and Paterno's statements to the grand jury don't entirely agree, so exactly what he told Paterno isn't certain.) Paterno notified the athletic director and maybe the PSU vice president who was in charge of the campus police department; those two spoke with the grad assistant about a couple of weeks later.
No one's brought up the possibility that that D.A. was put into hiding by the government to protect him. That leaves the other two possibilities you mentioned but investigators and people who knew him can't think of a reason for either.
I've seen Sandusky's wife mentioned in articles but not in the present tense, so I don't know if she's still around.
To elaborate on Justin's answer: In the e-mail that the AP got ahold of (see the post above), McQueary claims he did notify the police. But in the grand jury presentment, according to his testimony, he did not.
The rape that McQueary witnessed happened in 2002. Sandusky had been investigated by the district attorney and the campus police regarding another boy in 1998, but the district attorney decided not to bring charges against him. (This is the district attorney who vanished in 2005; people who knew him said that for him not to have brought charges in 1998 or 1999, he must have felt he didn't have enough evidence.) The investigation that led to the grand jury which issued its report early this month started when a mother of another boy complained back in 2008 or 2009.
Sandusky had retired as assistant coach when that incident occurred, so he wasn't McQueary's boss or otherwise above him in the football program's hierarchy. (He probably still commanded a lot of respect, though.)
But more to your point, I'd like to note that David Brooks's column in The New York Times earlier this week was about this.
I've never heard of a child molester who, before they acted on their sexual impulses, went to anyone and said "I have these terrible desires, please help me."
I once read such a letter to the sex advice columnist Dan Savage. I didn't find that particular column when I searched his archives, but I found a few other letters on the subject. Here's an old column that includes one such letter (it's the third one). The following week's column includes a first-person testimonial on the matter (it's the last letter) and more from Savage. (He claims, "The overwhelming majority of pedophiles never, ever act on their desires," by the way.) Here's a more recent column with a similar question, the response to which includes thoughts on the matter from a psychologist who's apparently an expert on pedophilia.
@orangebanshee: Did they request his SS# ? I'm an authorized user of my father's credit card and his bank apparently requested mine, because that credit card account shows up on my credit report as well as his.
Re: Your Gawker Media display name Have you ever listened carefully to, or read the lyrics of, "Rockin' in the Free World"? It's clear that Neil Young means to mock people who are "rockin' in the free world" with that line. Please tell me I've ruined the song for you now.
Ha. But she would write that it is indeed a ballistic missile facility, no?
Anyway, I've seen another news article that said some speculate the CIA or the Mossad was likely involved. I wonder why the Revolutionary Guards would want to hide the fact it was an attack or an act of sabotage, though. Wouldn't announcing that rally support for the struggle against the West and Israel? #tips
I thought Björk had a last name so I looked up the article about her on Wikipedia. There's a link to this article at the top. So they do have last names; it's just that their last names aren't family names.
