I guess there are many scenarios, but in terms of which index you set up, you can, of course, take from found human remains with the coroner.
When you have a missing persons report with police and whatever protocols you attach to that, you may take samples, with consent, from the missing person's hairbrush or something like that, which could bring them into the scope of the system, and again, with consent, their relatives.
If you go back to that second circumstance, that reported missing person and what their consent is and what their perceptions are, their privacy assumptions, again that's one of the issues, as Mr. Yost has said, that becomes complicated.
But in another context, I guess that sort of speaks to not just the informed consent that would take place, but again, as Dr. Fourney knows, how do you report back matches to police and jurisdictions, and how could those be controlled, the results in a report?
