TDLR: New lead: a creepy french guy named Stéphane Bourgoin, claimed knowing the killer of Eileen in California. Where should I start ?
Long version :
Hi everyone. I am new here (first post). I just want to say that I think I have a lead to suggest about this case.
There is a guy in France, Stéphane Bourgoin, which is famous because he is a con artist, he pretended for years to be acquainted with serial killers whereas he had no specific training (not a cop, not a psychologist, nothing). He was on tv and everything, sold books, considered by many as an expert. BUT he was finally debunked - it was mostly all false.
What is super weird about this, is that he was super-fascinated, even creepy, when talking about serial killers. He went all the way to claim on facebook that he had the body of a serial killer in a box, and said that he sold body parts (teeth, ears, etc).
So to me, that guy was more than a mythomaniac con-artist, but actually he might be dangerous.
The reason I am posting this here is because he claims that he was in the US, from 1975 to the 90s (?), and in California specifically in the 70s. He claims that the first murder case he was drawn to was a "friend" he was dating, that got brutally murdered. But he never explained properly who was the serial killer (details don't match to anything on record), the only info he did not change, for years, was that this friend name was Eileen, and that she was killed in 1976, in California (!!!). He claims (but that part was debunked by journalists in France) that the serial killer that killed her was arrested in 1978 and that the sheriff allowed him to meet the killer for his own grieving.
I looked online and quickly found this Eileen. My point is : could this Eileen know this French guy? Can we get any detail that could support or deny that claim? Could he have killed, kidnapped, or be involved in her case? Honestly, I thought that he might be telling the truth about "Eileen in California" because the guilt/trauma of doing something bad to her could have made him insane, becoming mythomaniac or something ? Idk, just hypotheses...
I can start getting info if possible, but I guess you guys know better how to deal with this kind of lead (and I'm super busy these days but I couldnt just sit while having this question).
So ... What can I / can we do to investigate that lead?
