@CaliforniaSleuther Thanks for mentioning it. Yes, it felt kind of snippy but I stepped over that already. No hard feelings. Your attention and time into this is appreciated. I was trying to help the case actually by pulling up other files about your suggestion Gonzales. I thought it was good thinking of you that Gonzales might have been Caucasian/Hispanic and it turned out he probably was (per Family search) From experience I know that a lot of people who are listed as Caucasian are actually Native American or Biracial. That's why it's always good to sleuth a little further and check out other info about a missing person. In the end it's indeed always about the likeliness a missing person could be a match with a UID.
About your potential match with Gonzales: In the process of considering him as a potential match I totally missed that he is probably already on the rule out list, named as Steven Gonzales.
About using isotopes. Personally I consider this in 2020 an old school technique. Time and time again isotopes have proven not accurate, covering a to wide span of possible states, so not very helpful in pinpointing things down. Especially in the US, in contrast of f.i. Europe, isotopes don't have that much distinctiveness. DNA has much more potential (if there is something to compare it with), especially combined with gynecological (just in time....thanks to Mrs Badcrumble....I mean Genealogical
) research. That is why this John Doe is "adopted" by the DNA Doe project. You can find him here.
