I'm quite sure that the authorities have been all over the area. Since they had dogs and helicopters out searching, you know they've been over ever inch of the place.
Also, as previously stated by somebody else, it is IMPERATIVE that none of us take it upon ourselves to go searching. 1 you might get in the way of a certified SAR group or police investigation, 2 you might very well destroy or contaminate evidence, and 3 it looks like she's no longer in that area.
Though it sucks to be so helpless in this, we can only hope, pray, think good thoughts, or whatever you do.
I am watching many caching forums and area news websites. The second I find out anything, I'll pass it along to the mailing list.
