Just catching up with this thread after recently finding out about Ruth's disappearance and watching the Martin Bright/Liam MacAuley documentary (Vanished: The Missing Surrey Schoolgirl). It's an intriguing case, and there are many interesting points and theories in this thread. A few other thoughts have come to mind:
There's a detail on Nesta Wilson's death certificate (attached in this post:
UK - UK - Ruth Wilson, 16, Dorking, 27 Nov 1995) that caught my attention, one that I don't think anyone else has mentioned - that Nesta died at hospital, so some time after hanging herself. So desperately sad. Perhaps this aspect affected Ruth badly, too, as well discovering how her mother died.
Also, like others here, I have wondered if Ian Wilson had any involvement in Nesta's death (directly or indirectly), and wonder if the possibility was considered or investigated sufficiently at the time.
The open letter Ian wrote to Ruth in 2006 (Daily Mail, 21.12.2006) seems very strange - quite narcisistic and victim-blaming - as suggested here: THE EXTREMELY BIZARRE & MYSTERIOUS DISAPPEARANCE OF RUTH WILSON, Cold Cases with Colette
(analysis of the open letter from ~27m 10s). The letter begins: "Dear Ruth
, We still have the presents we bought you for Christmas in 1995.", full text at: 'MISSING: OPERATION SCHOLAR: RUTH WILSON' by scepticpeg:

Apparently, a body can easily be missed, despite intensive searching for four weeks, eg Richard Morris, diplomat missing for five months before his body was found in August 2020: BBC News 'Richard Morris: Body found in search for missing diplomat':
Richard Morris: Body found in search for missing diplomat However, I am not sure this is a good example, as I would lean towards the theory that the body was placed there after the search.
I'm fairly conviced Ruth went missing deliberately and is out there somewhere - that's what the available evidence seems to show, and that she had help, and someone knows more than they are saying.
