If Kohberger is the killer, and if he appeared to react a bit more to the reading of Xana Kernodle's name, might it be because, per the PCA, Xana Kernodle may have been the person to whom he said, "It's okay, I'm going to help you"?
Per the PCA: "D.M. stated she opened her door a second time when she heard what she thought was crying coming from Kernodle's room. D.M. then said she heard a male voice say something to the effect of "it's okay, I'm going to help you."
Those two sentences of the Probable Cause Affidavit were the most heartbreaking, to me, because they caused me to feel that Xana Kernodle may have been the only one of those four young people to realize what was happening and/or about to happen. I would prefer not to believe that, rather very much prefer instead to believe none of them knew even a second of their fates, but when it comes to Xana Kernodle, I think the facts, when and if revealed, may prove otherwise
My opinion only, JMO.
