Huh?
1. JR, the self-proclaimed last person to see LS alive, has a story (he watched her walk solidly to the corner and turn) that some say is impossible on his end (he couldn't see her from that vantage point at that hour - personally I've never been convinced by this charge, but many are) and either way appears potentially impossible on hers, as it is seriously inconsistent with the testimony of several people that at 2:40 (and perhaps 3:40) she was inebriated to the point at which she could not talk or walk (itself supported by JR's story, who suggested he needed proof otherwise). We cannot say the same of any other POI - MB's story that he was working on papers is supported by their being turned in the next day, CR's amnesia story is supported by rumored xanax use and/or the videotaped assault, JW's story is supported by the testimony of his roommate, absence of any evidence he ever left home, and LE access to his/her phone and his car, and DR's story is supported by SW camera/entry data, LE access to his phone, and absence of any evidence he was involved past 1:30-45. Whether or not any of these stories are true, they at least make logical sense (JW went to sleep before the confrontation occurred). JR's does not.
2. JR was clearly awake (or passed out in LS's presence) circa the time of her disappearance, per the cellphone call from his phone. We cannot establish that that is true of any other POI - that is an hour at which most people, even partying college students, are asleep, or maybe pulling an all-nighter. We can also establish it is not true of at least two POI - CR (who has been poly'd along with his roommate), and JW (whose roommate has told same to Federal LE, presumably on pain of false statement and obstruction of justice charges).
3. JR has not submitted to a LE polygraph, preferring a private administration (as indicated by his lawyer's statement re providing results to LE). JR may not in fact have ever spoken directly to LE. We cannot say the same of any other POI - CR and MB have submitted to LE polys, DR has spoken to LE and may not have even been asked to take one, and JW's statements, while arguable, suggest (to me) that he took a LE poly, consistent with LE's description of him as cooperative two days after they administered polys to CR and MB.
4. JR has not spoken to anyone in the media. We cannot say the same of any other prime POI except MB (iirc) - CR and DR have spoken on camera, and JW's media contact is now infamous here.
5. JR may not have participated in any searches (though I'm not sure about this one). We cannot say the same of any other prime POI - CR/MB asked around about the "little blond girl," and DR and JW have participated in volunteer searches.
6. JR supposedly skipped town fast; at least, we have no evidence that he was around after 6/3. We cannot say the same about any other prime POI - JW was around until at least 6/9 or 10, and CR/MB and DR until at least 6/17, if not longer.
I mean, what am I missing here?
