We focus a lot on the town of Delphi but looking at google maps, the outlying areas are dotted with a lot of farms and acreages reaching out in every direction towards surrounding towns and cities.
So my first thought was somewhat of an unfair stereotype. I imagined a recluse who lives in a ramshackle house in the country near Delphi, ridden with junk, raises chickens and a few head of cattle. Not really a farmer but a jack-of-all-trades who makes do without requiring any additional income. Nobody keeps track of his comings and goings, he’s still living in the same house he was born in, he keeps to himself. The sort of introverted person who almost always walks looking downward. He’s familiar with the bridge, memories too as he spent time there on outings with family or friends as a child. Over time his isolation has grown into private perverted inclinations and alcohol gives him courage. People would describe him as “odd” but nobody really knows much about him anymore other than by sight. All JMO
Unless, the murderer catfished them, posing as a male friend or interest. Something definitely made them uneasy to a point they found him "creepy".
