Reply #13: Don't get yourself into any trouble trying to help out.

I don't know the specifics, but if the parents have already notified the police, you might want to let them handle it and just try to be there for the parents until she comes home. Now, if there's any reason to suspect that the girl is in immediate danger, such as if the boyfriend is abusive or something, then make sure the police are aware of this and things might move along faster. Otherwise, unless you want to do your own stakeout somewhere you think she may show up(which still could get you into legal trouble), there's probably not much you can do yourself. Come to think of it, ask the officer(s) in charge of the case how you can help out. They'll probably tell you there's nothing, but it never hurts to put another human voice out there to associate with the case.
