Replying to my own post because I just read more about this case in some links.
From what I read, it appears she was dropped off at her apartment after the date.
If so, that means she was either taken right from her apartment or she had left the apartment after the date on her own, and then was abducted somewhere else.
Since the car was found at another location, it seems to me that she must have left the apartment in her own vehicle, and then she was taken while she had her car out. I would hope if she left the apartment, that maybe she told someone where she was going. That would at least provide a clue as to where she was heading.
It is like others said. Either she drove to that spot and was taken from there. Or she drove somewhere else, and then the perp(s) dumped her vehicle where it was found.
