I don't know if Macon Mom is still around, but, I am pretty sure I still have on an old drive, some postings and pictures he posted. I was so weirded out by that site and the stuff I found, not to mention what happened after, that I dropped everything and ran. Sounds like LE was on the receiving end of a bunch of it anyway.
It's possible that nobody knew Lauren was missing an earring, but one was found and determined to be Lauren's through DNA.
Most important to me is what may have been found along side the earring in the earring recovery location. I may have missed precisely where it was found in his car. Was there biological material along with the earring? Her earring being there by itself may not amount to much other than to say she was in the car. WHEN was Lauren last seen with that earring on (if it's hers)?
I still can't believe her other remains haven't been located and it makes me so depressed.
I can only pray when the evidence is revealed and he is convicted, that one of his family members might convince him to reveal the location(s).
I have a good many of the OC posts but I know my "file" is not complete. (Looking through them tonight, I even found one where he posts about a way of cutting a person's carotid artery and windpipe -- but the posting year is "wrong", since they are saying the post mentioned at the most recent hearing is from 2008.) I have none of his posts from 4C or 99C.
I have sort of a hunch this newly-mentioned post might be from a different type of site (not a chan site), but it is only a hunch.
The earring: You are right, if it's Lauren's, it could bear her DNA. (That didn't jump to my mind immediately, so I'm glad you mentioned it -- I was busy wondering if anybody knows anybody else's earring collection by heart! What I came up with is, while another person might not be able to "recite" the list, someone close might very well recognize a particular earring and be able to say, "Yes, that's hers.")
The earring was found in the glove compartment of the car. If you look at the first set of pretrial motions (the only ones we have seen in print), you can see the warrant and the warrant return for the car search, included as background material for the motion (it's Motion 2.8 in the document at the link below):
https://www.documentcloud.org/documents/540762-mcdaniel-defense-motions-351-pages.html#wgt=rcntnews
Also in the background documentation included in that motion is mention of "dark stains" on the front and rear seats, which are described as appearing to be possible blood stains. What we don't know, of course, is whether anything in there tested to BE blood.
I did notice that the recently-filed motion (the one the judge granted, linked a page or two back) regarding the exclusion of luminol testing from trial described such testing in Lauren's apartment, Stephen's apartment, the downstairs apartment and refrigerator, and the laundry room. We know now that luminol suggestion of the presence of blood in any of those places was NOT confirmed by other testing.
The car is not mentioned in the luminol motion, and luminol or other testing for blood in the car is not mentioned in any of the background documents for any of the motions we have seen. (We have not seen everything there is to see, of course -- only the warrants, reports, etc., that the defense needed to include in support of its motions... and only for the first "set" of motions.)
So, I'm left wondering if luminol was possibly used in the car?
IF it was, and the car was not included in the motion to exclude luminol results, it
could mean (a) any luminol results in the car were negative
or (b) luminol tests in the car were suggestive of the presence of blood and further tests confirmed the presence of blood. (Quite a difference between those two possibilities!)
ETA: Adding to this that all I have said here has to be taken with the knowledge that there was much of the hearing the other day that I did not get to see -- so some of my "we don't know"s and ???? could have been covered there and I (and the print media reports) just missed it.
