I think that just reflects a kind of cursory look at the case, where circumstantial evidence strongly implicates a certain person. Once you get into the details, though, it's much harder to say that person is guilty, and at very least couldn't have acted by himself.
It's hard to say what LE thinks. The feeling I get is that they don't have the slightest idea who the actual killer is.
I'm not sure what I think LE knows. I want to think that even if they don't have sufficient evidence to charge anyone yet, perhaps they pretty much have most of this puzzle nailed down, with just a few pieces still missing to complete the picture. But you may be right, and they are completely confounded. I do believe the forensic snapshot threw them for a loop, as I think it did very many of us, including me. It is almost unbelievable that with the cast of characters we are aware of, the murderer is most likely someone else, even though one or more of the people we know of may very well be involved on some level. I do believe KR knows far more than she has told, and may even know who the murderer(s) is/are. She may or may not have known immediately, but I believe she has known since at least shortly after.
As someone who came into this thread very recently, I would like to just add my thoughts to those already posted by many others. I would almost bet dollars to donuts that the writing on the Time Out bag was done by two people. The size, and slanting of the words are clearly, to me anyway, two distinctly different styles, and yes, the use of the word 'jealous' seems likely to have been from a female, imo.
As to the butt-dialed voice mail, I couldn't make anything out of it that would indicate it was made anywhere other than the club. LE would know for certain, bc they would have been able to see time stamp on the receiving phone as well as Faith's, and if it, as the man who enhanced it suggested, recorded her murder, it would have been made after the texts to BE, rather than before. So unless LE is lying, and I see no reason why they would on this point, I am comfortable that the vm was made earlier in the night, while at the Thrill. I do think it is possible that the vm recorded at least a small bit of what may have been anger or an argument, but how important that may be, if at all, I am not sure.
I am struck by how much Faith and KR looked alike that night at the club, hair done up the same way, almost identical shorts and tops, and of course, their skin tones very similar. I doubt that was just a coincidence. I do think it could be possible that, especially given that Faith was found in KR's bedroom, it could have been a murder meant for KR, although I really find that to be unlikely. What I find more interesting is that one of the two, either Faith or KR, seemed to be trying to emulate the other in style, which could indicate a relationship that could result in jealousy if one got more attention than the other. I wonder how often they looked and dressed alike when they went out. I dunno why, but I just doubt it was a one-time thing.
Finally, a thought on the semen found, reportedly ON Faith. I read in a News and Observer article that I can't find to link to atm, that the semen sample came from a rape kit, which leads me to think it may actually have been IN Faith and not ON Faith, or at least in addition to. I think this is only important in that if it was found IN her, it would tend to erase any thought that the semen was planted on her.
Nothing new or earth-shattering here, just some thoughts to add to everyone else's. I do so hope that the coming anniversary will bring new information from LE, and may spark renewed interest and allow this case to finally be solved. As always, JMO
