Also known as the Pope Lick Monster, named after the Pope Lick Creek near Louisville, Kentucky that it (he?) calls home, the Goatman might be a form of Sheepsquatch, a particular type of Cryptid known for being furry and having horns (sorta like the Wampa in THE EMPIRE STRIKES BACK). Or it might be a faun-slash-satyr, the goat-legged (and horned and hooved) creatures from Greek mythology. It might be the god Pan himself, somehow ended up in Kentucky of all places. Or it might just be an urban legend and nothing more. But even if the latter is the case, the Goatman has killed a number of people. He has more deaths to his credit than any other Cryptid, unless one wanted to blame Mothman for the bridge collapse.
See, people regularly hop the security fence and walk out on to the railroad trestle over Pope Lick Creek in search of the Goatman. And trains cross over the trestle several times a day. It’s all too easy for a person to get caught out on the bridge in the path of an oncoming train with nowhere to go except to leap from the trestle, and it’s a long way down to the creek below. Alternately a person could take his chances with the train, or try to hang from the trestle like the fellas did in THE LOST BOYS. But holding on to a violently vibrating rail for as long as it takes for a train to pass isn’t that easy.
Some claim the Goatman uses hypnotic powers to lure victims out onto the trestle. I would tend to blame an imprudent sense of adventure and lack of forethought, myself. And I’m speaking as a guy with an imprudent sense of adventure and notorious of a lack of forethought. I’d probably be too lazy to scale that fence, though.
