First of all, if you haven't seen the movie, check out the trailer below:
The director of the horrifyingly disturbing documentary revealed that a scene involving Jan Broberg's mother Mary Ann and a gun was edited out of the film.
Filmmaker Skye Borgman left out a scene which featured a meet-up that Mary Ann had with Robert Berchtold in a car park, allegedly involving a firearm and her brother (via Vanity Fair). So it looks like the family were way more concerned about Jan's kidnapping than a lot of the documentary makes out.
