Bill Harvelle

Bill Harvelle was a hunter and husband of Ellen Harvelle as well as the father of Jo Harvelle. He was owner of Harvelle's Roadhouse along with Ellen--the bar was well known among hunter circles and John Winchester was known to frequent the place. According to Ellen, John became like a member of the family after a time. Bill was an accomplished hunter and routinely hunted alone, but during one hunt, John accompanied him, tragically Bill is killed by a demon when the salt line that was drawn around him was smudged by John's boot.

John describes this in a journal entry:

''It looked like smoke and sounded like a million flies. Bill looked down from the stars just in time for it to flow right into him. He started jerking like a condemned man in the electric chair, and two voices were coming out of his mouth. One was the thing, the hellspawn. I don't know what language it was speaking, but its voice was horrible. It was the sound cancer could mak if it could talk. And Bill, he kept saying over and over again, John shoot me, shoot me, John. So I did. It was the worst mistake I ever made. ''

After Bill's death, John is overcome with guilt and does not visit the Roadhouse again for nearly twelve years. He still carries the guilt with him as he tells Sam and Adam during one confessional to them.
