During the Penn. press conference I was struck by the (county?) Asst. DA from Penn saying that he thought kuhberger waived contesting extradition was the "need to know" what was in the arrainment documents:
(time 20:25 - 20:45)
I think that is a directly reference to Kohberger having to, every day, add to the circumstantial case against him by being observed continually and obviously attempting to hide DNA sourcing at his Pennsylvania residence, eg placing his garbage at neighbors, using gloves etc.
He needed to know if they had his DNA at the scene or not. If not, he would not have wanted to be observed doing what he was doing with the garbage and would be able to stop.
By the way, those PA cops and that shlubby/disheveled but cool coded language dropping DA fit every positive stereotype I hold of PA staties and DA's I have known.
