I've been having similar feelings, but to some extent, these especially well-publicized cases where someone is still unidentified, it makes sense that the person was never reported missing--otherwise the case would not have required DDP to be solved. And as more and more people are added to NamUs, with DNA, many cases will solve themselves, so to speak. But DDP and LE can't always investigate every case in the same way. Look at Lina Izaguirre Reyes's identification recently--there is such a backlog of older cases, not always with DNA available, not always with family present locally or otherwise to push LE for ongoing investigation, that there is still room for forums like this. I've also noticed some people moving to strategies of searching old newspapers, Ancestry, etc., for the missing that are not in NamUs--I myself have been taking note when I see posts shared on Facebook of family looking for someone that is missing or with whom they have lost contact, but perhaps has not been reported missing for various reasons--I think this is another strategy that may eventually bear fruit.
