The case inspired Frank De Felitta's 1978 book The Entity which was made into a 1982 film of the same name starring Barbara Hershey.
At the time, Taff was working in the now defunct parapsychology lab run by Thelma Moss at the University of California, Los Angeles.
[1][6][7][8] During the course of their visits, investigators noted what Taff called poltergeist activity: objects falling from shelves by themselves, strange lights, bad odors and cold zones in the house.
[8][9][10] An analysis of the photographs attributed the result to common photography mistakes, such as a thin object close to the camera, or accidental manipulation of the exposure dial.
[10] Based on Bither's story, his own observations, and the photographs, Taff concluded paranormal phenomena must have been involved, calling the case a haunting.
