To clarify your clarifications.
The name of the photographer is known (I didn’t mention ‘publicly’)
The name of his companion is known.
The photographs were published.
I didn’t bother to read past those first three points.
Maybe you are confusing what you know with what others know.
I'm genuinely not here to argue with strangers on the internet. Self-evidently, others know more than us, which is why I'm on here asking for people's help. If you know about this case, would you please talk to us and fill us in?
If you'd like to speak to Dr Clarke privately, I can get him to contact you at your convenience if you would provide me with your details.
I genuinely don't know of any publication of the photos. If that was in a newspaper or journal that's publicly available, please would you enlighten me?
