I just wrote this for the general thread and it was closed as I tried to submit:
Wow. Pretty significant development today! I have read through most of the posts, but not all. I suspect that this was probably covered. I see that many posters have suggested that this may be a case of mistaken identity. That is possible. I remember learning about witness accounts not being very reliable. Perhaps LE has already discounted this witness account, but perhaps it is still part of their investigation. IDK.
As you know, I don't know much about these things, but it seems to me that this woman's sighting was recorded by LE. It also seems to me that this information would be part of their investigation, so in a way it is not surprising that there is a witness(seemingly unconfirmed) that we don't know about. LE is not sharing information related to their investigation.
There may be other witnesses that have possibly passed on information to LE. I would imagine that is the case. Who knows what we will learn? Some witness accounts will be credible and some of them will not.
THE FOLLOWING EXAMPLES ARE NOT REAL AND DO NOT EXIST TO MY KNOWLEDGE: It is possible that there were witnesses that saw BC driving down the road just after 4 am, NC being dragged into bushes at aroung 8am, BC taking something out of his trunk and then being spotted and driving off at about 5:30 am, NC having breakfast with a friend at JJive at around 9am, BC getting his car washed at around 1pm, NC coming home after the BBQ at around 3am, BC buying more tide at 1:30pm . . . . . You get the idea.
The point is that we really don't know what information is going to come out. Will we ever know all of the details of the investigation? I gather from RC's comment that there will be a detective witness tomorrow. Who knows what will come out there? I suspect that it will be very interesting.
