I was reading about missing cases and I was surprised by how many people simply vanish, never to be seen again.
I don’t know of anyone personally who has just disappeared, but many years ago before my Dad retired, he had a work colleague, who was in his late 50’s, he left his work place and he’s believed to have never made it home. He simply just vanished, his family spent months trying to find him, there were no letters, or clues to his whereabouts and as far as I know, still remains missing to this day.
