The Smurl haunting chronicles the Smurl family's claims of demonic activity in their Pennsylvania home from 1974 to 1989. Demonologists like Ed and Lorraine Warren supported the family's claims, while skeptics attributed the events to psychological factors or hoaxes. The story gained significant media attention, resulting in a book and a TV movie. Conflicting accounts emerged from various individuals and sources, highlighting the debate surrounding the nature of the reported paranormal activity and the credibility of the involved parties. Ultimately, the family moved, and subsequent residents reported no supernatural experiences.
