Many have speculated he grew up in Delphi, or lived there at some time. I would think he would have been recognized? My guess is he has come in to Delphi for work. Perhaps a factory worker, or a traveling salesman selling tractor parts...that sort of thing. In addition, one thing stays anchored in my mind. I believe this was well prepared in advance, and that he had catfished Abby. I dont think there is anything random about this at all.
