Welcome to Webslueths. I completely agree with you and also feel he was likely “well off” or at least middle class. This case seems solvable. I can’t help but think that there is/was a BMW sitting abandoned somewhere (quite likely at an airport) or maybe it was abandoned in the care of someone? But if so, why are we not seeing a missing person’s report? This makes me think that maybe he’s foreign. I get that the report could have been lost, but being foreign might also explain why anyone close to him has yet to locate him.
Thank you for the warm welcome! Yes, in my opinion he was "well off too" and this case seems solvable if the man is not foreign, although who knows, with a lot of cold cases being solved now maybe we have the technology for a lot nowadays, that is great!
Your statement of the BMW makes a lot of sense, although some people (sadly) don't care enough to make it because of their relationship to the person or they simply assume they are likely fine. He might have rented that BMW to travel around California if he had been foreign, or even if he was not foreign he could have rented the car, but maybe using "Paul Deering" too or maybe another fake name, or maybe the BMW was actually his.
Him being foreign actually makes sense, because maybe he left family behind that is actually looking for him, but maybe they did not know he was going to the US, or maybe they did but they have no way of contacting the US to look for him. I might be reaching here.
I decided to check what destinations LAX Airport has on the Wikipedia page (Although I should have possibly looked into the official website), and I am basing myself off into what I said about him "Looking" Eastern European or Mediterranean. We are assuming he either was leaving back home or he came to the US through that airport from some of these destinations.
It appears that they have flights for Tel Aviv (Israel, Mediterranean, although he does not strike me as having jewish ancestry) Madrid (Spain, Mediterranean, although he has more of a "slavic" look, but I can see how he could be from here) Warsaw, Chopin (Poland, Eastern European, I really see this) Zurich (Switzerland, more like Central Europe but it can be a lead) Frankfurt and Munich (Germany, more like Central Europe but it can also be a lead) and Instanbul (Turkey, far off and I highly doubt it, but it can lead us somewhere)
If he were to be foreign, I would say he more likely came from these areas.
