Do you have a link for this info?
This is entirely my opinion, but just from the various reports that I have pieced together, I get the sense that her parents were probably embarrassed and a bit ashamed of her lifestyle, and while they may have made some calls and looked for her, I am not sure they applied much pressure to LE to do so. And even now I don't sense that they are applying much pressure on LE, as mom at least publicly says she thinks she is alive and just not ready to come home. It seems it was the ex-bf who any pushing to get LE involved. And I am not judging the parents, but if my child was missing, SOMEBODY in LE would be getting a phone call from me regularly asking for updates. Surely if a particular officer got promoted, his caseload would have been assigned to someone else.
