I've been thinking more about what might motivate everyone to keep quiet.
Sex surely qualifies, but they've all given DNA samples and their places have been searched, so I tend to rule that out (it still seems possible, certainly, but unlikely). [And as for the idea that "activity" means something, see the "just her presence" quote in this article -
http://www.heraldtimesonline.com/stories/2011/06/09/news.635642.sto - which also makes clear that there was just one person with her ("somebody else").] "They," however, means the known POIs. We still have a likely fourth person (beyond JR, CR, and MB) at 5 North who may not have given a sample. It seems unlikely, however, that they had sex with LS without JR's knowledge and that this led to her death in a way that is consistent with JR's story, which he's told to a polygraph. They might have, however, if he passed out, which seems entirely possible if xanax was involved. But this still doesn't explain how she disappeared (more on that below)...
What else would motivate their not talking? Well, drugs, of course - you can easily base a murder charge on them. I speculate, based on crediting what has been said elsewhere, that LS got drugs from JR, whether sold or otherwise.
But that's only one person. I have no good reason to believe she got any drugs from CR, though it seems possible. Assuming she didn't, what makes him clam up? It's been claimed that he was "aggressive" towards her (
http://www.examiner.com/headlines-i...f-last-man-to-see-missing-ny-coed-is-revealed). Perhaps that involved encouraging her to take more drugs (than she intended). Maybe it involved something else (non-sexual) that might have helped lead to a heart attack; that would be something to worry about as long as he's aware of the long QT syndrome. Makes sense, right?
As for MB, I don't really see how he fits in. Perhaps he was among the group at JR's - there's been inconsistent reporting on that score - and also encouraged her to do more drugs (or even supplied them). But if not, I would tend to think that he isn't talking because he really doesn't know anything that about the night in question that helps solve the case. One thing we know he does know, though, is LS' and CR's condition when they arrived home. For that reason, given his polygraph, I would tend to think the accounts we've heard on that score are reasonably accurate.
So I believe that JR and CR(?) aren't talking mostly because of potential drug-related responsibility, while MB (and CR?) can't say much because he(/they) doesn't(/don't) know.
But this doesn't explain how LS disappeared, of course. I can't come up with a scenario in which JR and CR dispose of the body without MB being involved. And I can't really believe that happened, given that they've all taken polygraphs. Of course, by that logic, it's also at least a little difficult to believe that JR disposed of the body alone or with some other person (though certainly possible - note the family's questioning JR's story that LS made the 4:15 call). Maybe JR and CR in fact (selectively) told the truth, and really have no idea what happened to her, but do know that they may well be liable for whatever did happen nevertheless. I feel like this might make the most sense from what we think they've said, as unlikely as it might seem.
But is there another theory that's consistent with their telling the (selective) truth that also involves their not telling the whole truth? Perhaps it's true that JR watched LS turn the corner alone, and that she seemed ok. But what if someone other than a random abductor knew she was coming around the corner and saw her later? Someone who was at JR's (and possibly but not necessarily involved in the earlier confrontation)? Maybe that person, I'll call them the Mystery POI (MPOI), had gone into the alley, either because they were heading home or in order to get their vehicle (perhaps to drive LS home, which supposedly was the purpose of the call to DR, or to drive home themselves). Whether or not she meant to meet up with this person, LS might have walked around the corner instead of into the alley because she didn't want to walk over the gravel on the way home/to meet up. Maybe something happened to LS after she turned the corner, after which she was found by the MPOI. Maybe this is even what was seen by the mystery witness, albeit at a different time than that reported. Suppose the MPOI disposed of her. Apply the same question - why would they do so? Because they had supplied/encouraged drugs as well and (knew they) might be liable on that basis? Because they are connected to/afraid of a drug network? Because they did something to LS? Hit her with their car (or startled her, causing a heart attack)?
Is there a way JR (or CR or perhaps MB) has not mentioned the MPOI and provided the relevant details to LE? It seems hard to imagine what the MPOI would have over JR (and CR). Is JR (and CR)'s own potential liability enough, knowing that fingering the MPOI makes it much more likely that LS is found and drugs discovered to be the cause of death? Perhaps JR has told the truth about what he knows, which is nothing about what happened after LS left (and CR likewise really doesn't remember). Is that possible? It seems likely JR would have contacted the MPOI (assuming he has their contact info), especially if they are an IU student. Could the MPOI have refused to respond? LE would presumably be all over them, in that case. Could the MPOI have simply lied to him and said they saw nothing? Probably not if he was supposed to drive LS home, but perhaps if they were both simply leaving at the same time. LE presumably would still be interested, however. Is the confrontation over JR's cooperation really about his willingness to speak about this MPOI? Is that why CS used all caps in her letter to a/the MPOI when she said "YOU HAVE NO IDEA WHO YOU HAVE TAKEN FROM US"? Because the MPOI didn't know LS? (this doesn't explain why she says "Perhaps we have met," or why she suggests the MPOI might know the family recently returned to NY for RS's birthday; those statements in fact might cause me to question my JW support if it were not for the all caps statement and the other evidence I've seen in support of the notion the family doesn't believe he's involved).
The big question, of course, is who is the MPOI? Are they perhaps the POI that LE had not interviewed and that had left the county (or State?) in this report (
http://www.idsnews.com/news/story.aspx?id=81889)? This assumes that that POI is not JR himself (the early reports are a little vague on this score, but do suggest that JR was interviewed in some fashion in the days after 6/3, if not necessarily in person).
Is this a crazy theory?
