I understand the need for flyers, appeals for information, even a reward in cases where the missing person has disappeared in a populated area. Scenarios like went to visit a friend and never arrived, or went out shopping and never returned, those kind of situations. But I can't really see what good they would do if she is simply lost in the desert. There is little to no chance that anyone saw her.
There are so many organizations that go out into the desert, though. If the facts as we know them are correct, she went missing near a research center and near a major Mojave attraction (Granite Peak). ATVers, climbers, rock hounds, photographers, archers, star gazers, mountain bikers, hikers, drone clubs and others all go out there, and many are organized. In fact, I'm in touch right now with a friend from a nearby city (former LE) who is thinking about taking 2 other people out there to search. Would be better if organized, don't you think?
The "good" would be finding her body. At this point, for some of us, that's a major goal as I've stated previously. It would do some people (our VI and others) a world of good if she is found. And if she is "simply lost" then she can't be impossible to find. There are all kinds of known techniques for remapping a search under these circumstances and I'm guessing that *some* of the SAR volunteers would be interested in applying those techniques. However, regular individuals who are familiar with the desert are the ones most likely to find her body, IMO. This doesn't mean that her next of kin should just leave it all up to fate, they can encourage the rest of us to keep working on the case. If in fact the next of kin (RT) wanted some help in this sad task, I could definitely put him in touch with various searchers (as can many people here on WS).
If it's the cost of these kinds of things that is daunting, there are people who specialize in organizing fund raising for missing persons.
I'm not saying RT has given up (perhaps he's grief stricken and devastated). But he has family too, younger people around him who could help give structure and incentives to a search for Barbara.
Some people feel it's not that important to search for a dead person, but many many others still want to help. Seeing her before she went missing isn't that important now, but finding her is still important.
