Good point. The video showing the brother meeting with Audrey, makes the case that none of the family has seen her for 62 years as the embrace looks authentic, not as if there is a ruse going on with the media and police.
If there is a ruse then it would be entirely within the family itself, no involvement with the media or the police.
There is some reason why they requested that what she had talked about with the police not be shared.
What exactly that may be, I have no clue or guesses as to what that may be beyond continued fear of her ex.
