The Smurl family: these unfortunates were the target of what I think can reasonably be called one of the most frightening hauntings in history. In Ed and Lorraine Warren discovered that the home was occupied by two minor spirits and one powerful Demon.
I have a different view of this picture posted on this board, but this view shows more of the grave site. Tom Petty snapped this picture of Jim Morrison's grave site, which shows his image in the background. Considered an authentic ghost photo.
