I should also say that she could have witnessed something other than weenie waging. And depending on what she saw and who it was - it could be very detrimental. And that could be a reason to kill her.
What I find so interesting is that the two men leaving the stacks and one saying "someone better help that girl" were never found. Since the girl this was said to was in the English 501 class - it would seem he was not a member of the class. I'm sure that she would have recognized him.
But why were neither of these two men found? If neither one of them were involved - why not come forward. I can see not coming forward if the reason you were there was illegal or inappropriate. Were these two men together? The articles don't seem to be clear on this.
Also - the one article states she was in her Sunday best. I graduated from High School in 1969. That was the first year a female could wear pants to school. And it was very restricted only certain days etc. And I was in California which was pretty liberal. So Betsy would have been use to wearing a dress to class and if she knew she was having a meeting with a professor - I can see her in a dress. So I am not sure that her attire has any hidden meaning. Though I think it is important to keep an open mind.
Oops sorry that this post is so long.
Just curious, what other theories do you have as to what she might have witnessed? I am kind of stumped there myself, as I'm trying to think what you could REALLY be doing in a college library that would be so detrimental that it could justify murder. If there are some other theories you have, I'd love to hear them.
I also agree with your position that the "Sunday best" statement may be a bit overplayed. To me having read the coroner's report, etc., it doesn't indicate Sunday dress, especially in State College PA, which is about 10 years behind the times in the rest of PA, and also with a girl who came from a very religious upbringing. I think that statement has led to a lot of the speculation that she was meeting someone there, which I have never proven and believe to be idle chatter.
I'm doing some testing and I'm starting to think that perhaps the murder weapon was not a hunting knife. Based on the wounds, it's possible it was a folding knife of some sort. Which would open the possibility that the killer ALWAYS had it with him -- just as I always carry my own pocketknife, having worked many jobs where it was useful for opening boxes, cutting a cardboard or tie strap, etc.
One article indicates that an African student followed or chased one of these men until he got outside the building and got away. I have thought about this a lot. It's plausible that one guy might not come forward if:
He feels he has witnessed something amiss.
He suddenly notices himself being followed by *gasp* a black student -- probably one of the few in SC at the time.
He wonders in his head if the black student had some part in whatever he saw, and he outpaces him and feels he has gotten away.
He goes home on break or leaves college for the military or transfers out and does not realize that he saw a murder victim -- OR he spends the rest of his life worrying that the black man WAS the murderer and he narrowly escaped. He has a great story to tell his grandkids about "the day he almost got murdered in the library."
If he ever did come forward perhaps his testimony was such that police kept it from the press in order to further their ends with regards to the case.
OR: Guy was doing something untoward in library.
Sees girl on floor, goes and asks for help.
Reads later that it was a murder and realizes: "Oh crap, if I go to talk to police, I will have to explain WHY I was there."
Realizes he may be a suspect WHICH at that time was a rather heavy stigma, as mentioned in one of the newspaper articles.
Realizes he has no further information that is useful and remains quiet.
Just some possible scenarios I have thought of to try to explain that.
2nd guy, could be someone he just passes, mentions that he is going for help, and second guy goes for help and does not feel he has anything to contribute to police, same deal. Or the second guy is uninvolved...Or certain witnesses are mistaken in remembering two guys, as this is a somewhat contested point.
So many possibilities, so little facts.
