Fox News at Night spent the entire hour on this case.
Two things stood out to me. One, because this crime occurred during the late evening, early morning hours there will be devices, such as cell phones, going to and leaving the area of her home. This is how they found Kohberger. The number of vehicles would likely be a few because of the time of day and the remoteness of the area. There is a 45-47 minute window when it would have occurred.
The other is that after the first deadline of 5pm on Thursday, the person/s making the ransom demand would have likely checked their Bitcoin wallet. That is traceable, too.
I think they are going to have this figured out pretty quickly.
