about a German girl by the name of Anneliese Michel who was thought to be in possesion of demons or devils and went through exorcism (driving the devil away) in a Catholic church in 1980's. She died and at the last moment of her life she was believed to have got rid of the devil finally.
"Today, Anneliese's grave in Klingenberg am Main remains a place of pilgrimage for many Christians who consider Anneliese Michel a devout believer who experienced extreme sufferings to assist departed souls in Purgatory."http://en.wikipedia.org/wiki/Anneliese_Michel
