I agree with you actually and the Kims paid dearly for their role in this tragedy sadly. This has happened three times. If the locals were saying, I bet they are up on Bear Mountain...why would trained professionals knowing this has happened previously not have at least checked sooner?
There are several logging roads that come off of that road where they mis-turned - they were in the process of trying to search each of them with foot people, but even with 100 searchers, it wasn't enough. It's a Rubik's Cube situation.
