I have heard of this sighting. Mrs B must have been frantically searching for years after the dissappearance.There was a lead that’s probably worth pursuing. In Feb 1967 (12 months after abduction) there were 5 friends and Nancy Beaumont herself who were so adamant that they identified Jane Beaumont in TV audience of a Chanel 10 show (pied piper) that they contacted police. All the people who attended were identified except for that girl who gave a false name and address. Why? Suspicious given there were prizes on offer.
Let us assume for one second that the 6 weren’t mistaken (6 is reasonably persuasive) and that it was indeed Jane who had at that stage been brainwashed into being cooperative with her captors. We all assume that they were abducted abused and immediately killed. But what if instead (god forbid) they were held captive as pedaphile slaves for some time at a place like that Yatina hotel by a gang. It’s possible (Stockholm syndrome) they become compliant and a reward was her attendance at that show. If she went she wouldn’t be allowed to go alone. Rather one of the perpetrators would go with her. Given that all names checked out as real then the police would know the identity of that person as being one amongst those names. Probably one who hadn’t yet been identified as a pedaphile but now 50 years later possibly has criminal record.
It should be an easy thing to review that list again and check pedaphile criminality. Long shot perhaps but a viable lead I feel
