Yeah, more out of the way places where someone is comfortable or aware of because of a hobby often end up being places that come into play with missing people and where they leave them.
Danielle VanDam's body, for example, was left by David Westerfield off the side of a road that's one route to get to the desert where he liked to go camping.
I'm hoping that long before his name got out there - since they had said he was a POI even prior to the crash - that they had copied everything from his SM accounts knowing he may delete things, as looking at places he frequented or knew well likely are good points to search.
