DJ,
First, may I suggest checking out this post about how to use the comments feature:

Second, I do feel for you and appreciate your situation. But I fear there is little you can do at this point. Your daughter has made her choice, as bad as it may be. The only thing you can do is try to let her know that no matter what, you still love her and want to help and be supportive.
The police are looking for the fiancee. If they find him and your daughter is not with him, she may come home at that point. If she is with him, they will probably bring her in too.
