After many decades identified only as "Roland Doe" or "Robbie Manheim", the 14-year-old alleged victim of demonic possession was reported as being Ronald Edwin Hunkeler (June 1, 1935 - May 10, 2020) by the Skeptical Inquirer magazine in 2021.
One for the real life "Roland Doe" exorcisms is said to have been performed at the South City Hospital (previously St. Alexius Hospital) in South St. Louis, Missouri. The wing where it was performed was torn down in 1978. The hospital filed for bankruptcy in 2020.
