Some of us were talking about this on Twitter. He isn't the only young black geologist who has disappeared either. Wasn't there also one working for National Geographic? I think it's possible for a person to fall in unrequited love and stare into space moodily a lot and yet his moods have nothing to do with the crime committed against him. Especially if he's a geologist in wild country where you've got claim jumpers, old mine shafts,desert rat types with firearms etc. I hope the family gets answers.
