So when he picked up the trail, after coming across some clues, it was about five years later. So he came up on the corpse some time later. It's more or less set in the United States, but that doesn't change much - the statistics for missing kids and young women are staggering. It's probably up to tenth of thousands every year there that don't show up again.
And since there was no means of identification - who was the corpse in the train? Has he been building an imaginary person around her? Is there really some ghost? Not knowing what happened can be pretty much worse than facts - especially if there are so many shit things that do happen. The girl in the picture is one of those examples.
