In early January 1949, shortly after Harriet's death, Ronald Hunkeler began to experience strange things. He heard scratching sounds coming from the floors and walls of his room. Water dripped inexplicably from pipes and walls. Most troubling of all was that his mattress would suddenly move.

Disturbed, Ronald's family sought the help of every expert they knew. The family consulted doctors, psychiatrists, and their local Lutheran minister, but they were no help. The minister suggested that the family seek the assistance of the Jesuits.

Father E. Albert Hughes, the local Catholic priest, asked his superiors' permission to perform an exorcism on the boy in late February of 1949. The church granted Hughes' request.
