Everybody just hold on a moment here.
Look, as much as this comes as a shock to me, and as desperate as I am to finally see an end to this case, let's not forget that Mary Lacy's judgment in this case has been less than stellar. Remember it was just about two years ago that she tried to nail an innocent man for this when it was clear he was not involved, AND she's a lame duck in office. She'll be gone from office in less than a year, and her history with this case shows that she has an interest in clearing the Ramseys for whatever reasons.
I think it's also important to remember that none of this DNA was from sperm or blood, according the the lead scientists I've just heard on TV, but most likely from skin contact. The consensus is that the person's hands pulled her clothing off. Okay, but there is one important thing we're forgetting: DNA tests are constantly improving, which is a damn good thing, but those improvements are just as likely to find DNA not related to a crime as to find related. I say that because, if it does match the panty DNA, and I hope that Mary Lacy will have the decency to make the full test results fully public, it means that the DNA was left at some time on both articles of clothing, but it does not necessarily say how or specifically when, and there are any number of ways to transfer it, so what I'm saying is I think that if someone were to say, "this is important evidence and we should use it to cast a wider net," they are absolutely RIGHT, but clearing the parents seems to be jumping the gun a little bit, IMO. And the reason I say that is we should not be quick to ignore the mountain of evidence against the parents in the face of this, especially since there still isn't anyone to match it against.
I'm trying to keep an open mind here. Just saying.
