Just a bit of preparation. If the searchers should find a body, they won't be able to say right away that it is Lisa. After 13 days outside parents won't be able to identify her. At the most parents may be able to id the outfit. But LE doesn't always announce at that point. At 10 months she won't have dental records. So IMO the only way they will be able to id her is by DNA. That will take several days. Days can vary, 3-5 days or even 7-10 days.
So if we hear that searchers have found human remains, they may or may not announce that it was a child. Then it will probably be several days before they will positively id her.
