I know who I have in mind, but will bide my time on voicing that as I could be way off the mark! I think if she was out, and given the weather, she may have encountered someone who she knew who offered her a lift either to her mother's or to the boyfriend's. If she was at home, I still have a person in mind. I sadly don't think either way and after this length of time she will be found alive. And as others have said, I think too the police may have a suspect/s that for now they are keeping quiet on. Obviously this is still a live case and they are not going to divulge all they may know which may hamper their eventually bringing the case to court.
