I have now read several articles and yes, the male was supervising. Bringing me back to the questions I asked early on, do the parents of these girls understand that a male was going to be supervising them dressing?
There has also now been further clarification that the shower curtains are gappy and can be seen through. And the pool management acknowledge this.
The pool expects females to contort their bodies for their own sense of privacy as well! In a previously female single sex space. That Julie Jaman has been using for nearly 40 years and did not know the space was now in reality mixed sex.
So this male was also able to see Julie Jaman showering. So she was also feeling violated herself.
And apparently someone from the pool contacted the police to report but did so anonymously and would not give a name.
There are multiple sites with different articles about this now. But the story seems consistent. And some sites have stated they have independently verified with both police and the pool management.
