I listened to the Vanished podcast episode on this case a week or two ago and it has been on my mind since. It is such a strange case, but also seems like it would have such a clear solution. Given Marina's high anxiety and general personality, it is quite clear that she would not simply get up and leave if she was in her right mind. It does sound like she was absolutely experiencing a psychotic break- probably brought on by the high stress and anxiety. Is there a way we can get ahold of the video footage from her in the parking lot at the police station?? If they are denying any foul play then they can't argue against releasing it with an FOIA request...
