From the families, I thought I read MP saying that Libby put up a fight, but maybe I misunderstood? If so, I'd like to.get a better idea, it is important. Either she fought, and then someone should have had some scratches, or, she did not have the time, and then he simply got rid of everything that could have his DNA.
But about criminal DNA, he knows more that I do. Because if the LE are still sorting DNAs out (This was in mainstream news - I think the LE's name started with H, he said something along the lines, they needed to sort whose DNA was whose, or something like it)..., it means, BG got rid of at least some contaminated items. And I, for example, would not know how to do it, how to get rid of evidence.
Question, where did he find it out? Criminology classes, books or Google searches?
