10 Real Exorcism Cases That Remain Controversial

The ritual of exorcism, deeply rooted in religious traditions across cultures, has long served as humanity’s desperate response to what some perceive as demonic possession. Yet, few phenomena provoke such heated debate as the cases where these rites have unfolded in modern times. From levitating children to guttural voices speaking unknown languages, the accounts challenge our understanding of mental health, faith, and the supernatural. These 10 real exorcism cases, drawn from documented records, eyewitness testimonies, and official investigations, continue to divide believers, sceptics, and medical professionals alike. What makes them enduringly controversial is not just the eerie events, but the tragic outcomes, legal ramifications, and lingering questions about whether they represent genuine spiritual battles or profound psychological crises.

Each case below offers a window into the tension between ancient beliefs and contemporary science. Priests and investigators have clashed with doctors and courts, leaving behind diaries, audio recordings, and court transcripts that fuel endless analysis. As we explore these stories, we tread a path of respectful inquiry, acknowledging the human suffering at their core while examining the evidence that keeps them unsolved mysteries.

Prepare to delve into possessions that rattled communities, inspired Hollywood horrors, and tested the boundaries of the explainable.

1. The Possession of Roland Doe (1949, USA)

In January 1949, a 14-year-old boy from Maryland, pseudonymously known as Roland Doe, began exhibiting bizarre behaviour that escalated into what many deemed full demonic possession. It started innocently enough: scratching sounds in his bedroom walls following the death of his aunt, a spiritualist. Soon, furniture moved on its own, and Roland spoke in Latin—a language he had never studied—while his body contorted unnaturally.

Lutheran pastors initially intervened, but the disturbances intensified. Jesuit priests, including Father Raymond J. Bishop, were called in for 30 days of exorcism rites at St Louis University. Witnesses reported the boy levitating, vomiting strange objects, and his bed shaking violently. A diary kept by Father Bishop detailed over 48 pages of events, including guttural voices proclaiming hatred for holy water.

Controversy erupted post-exorcism when skeptics attributed symptoms to adolescent epilepsy or schizophrenia, exacerbated by suggestion. The case inspired William Peter Blatty’s The Exorcist, but Roland—later identified as Ronald Hunkeler—lived a normal life thereafter, fuelling debates over fabrication versus repressed trauma. No conclusive medical diagnosis was ever confirmed, leaving the case a cornerstone of possession lore.

2. Anneliese Michel (1975–1976, Germany)

Anneliese Michel, a devout Catholic from Bavaria, first showed signs of distress in 1968 at age 16, diagnosed with temporal lobe epilepsy. By 1975, her seizures evolved into what her parents and priests believed was demonic infestation. She refused medication, claiming voices commanded her to atone for sinners, and she engaged in self-harm, eating insects and ripping off her clothes.

Two priests, authorised by the local bishop, conducted 67 exorcism sessions over 10 months. Recordings captured her speaking in voices mimicking historical figures like Hitler and Judas, and she growled like an animal. Anneliese died of malnutrition and dehydration in 1976, weighing just 31 kilograms.

The ensuing trial convicted her parents and priests of negligent homicide, sparking global outrage. Critics pointed to undiagnosed schizophrenia or anorexia, while supporters cited her supernatural knowledge and physical aversion to sacraments. Forensic analysis showed no drugs in her system, but the case highlighted clashes between faith healing and medical ethics, with her story adapted into The Exorcism of Emily Rose.

3. Clara Germana Cele (1906, South Africa)

At St Michael’s Mission in Natal, 16-year-old orphan Clara Germana Cele reportedly made a pact with the devil after reading forbidden occult books. In October 1906, she levitated repeatedly—witnessed by nuns—spoke fluent Swahili and Polish (languages unknown to her), and revealed nuns’ hidden sins. Her body emitted foul odours, and objects flew around her.

Two priests, including Father Erasmus Hörner, performed a two-day exorcism. Clara contorted impossibly, her tongue elongating, and she climbed walls like a spider. The rites ended her possession, but she died shortly after.

Sceptics dismiss it as mass hysteria or epilepsy in a superstitious convent, lacking modern documentation. Yet affidavits from 24 witnesses, including non-clergy, persist. The case’s colonial context adds layers of cultural bias, making it controversial for its reliance on missionary accounts versus potential psychological explanations.

4. Anna Ecklund (1928, USA)

Born Emma Schmidt in 1882, Anna Ecklund sought help from Father Theophilus Riesinger after decades of torment beginning in childhood. She claimed her father sexually abused her, cursing her with demons named Beelzebub and Judas Iscariot. By 1928, at age 46, she could not enter churches, vomited profusely near the Eucharist, and spoke multiple languages with animalistic voices.

The exorcism at a Wisconsin convent lasted 23 days, with over 2,000 witnesses hearing her predict events and blaspheme. Father Riesinger documented her levitating and revealing audience secrets.

Medical experts later suggested dissociative identity disorder or Tourette’s syndrome. The public nature—attended by crowds—raises questions of performance, yet Riesinger’s detailed 1929 report, Begone Satan!, includes verified predictions, keeping the case divisive among demonologists.

5. Michael Taylor (1974, England)

Michael Taylor, a 47-year-old churchgoer from Barnsley, underwent deliverance prayers led by charismatic minister Ken Culshaw after confessing lustful thoughts. During the session, Taylor foamed at the mouth, growled, and prophesied doom. Believing 40 demons possessed him, including Satan himself, the group prayed for hours.

Released, Taylor murdered his wife hours later, dismembering her face and strangling their dog. He was found covered in blood, claiming demons drove him.

Acquitted of murder by diminished responsibility, citing religious mania, the case ignited debates on unregulated exorcisms. Psychiatrists diagnosed schizophrenia, but Taylor’s sudden violence post-ritual puzzled experts, influencing UK guidelines on deliverance ministries.

6. The Smurl Haunting (1980–1986, Pennsylvania, USA)

The Smurl family endured 18 months of poltergeist activity in West Pittston: walls oozing slime, foul stenches, levitating objects, and demonic voices. Jack and Janet Smurl claimed rape by an unseen entity, corroborated by their children.

Ed and Lorraine Warren investigated, arranging an exorcism by two Catholic priests. Activity worsened, with family members levitating and hearing incantations. They eventually fled.

Sceptics alleged hoaxes for attention, but utility records confirmed unexplained temperature drops. The 1986 book and film The Haunted amplified controversy, with no definitive proof either way.

7. Arne Cheyenne Johnson (1981, Connecticut, USA)

During the exorcism of his fiancée’s brother David Glatzel, 19-year-old Arne Johnson challenged demons to possess him instead. Days later, he stabbed landlord Alan Bono 22 times, claiming possession in the infamous “Devil Made Me Do It” trial—the first U.S. case allowing demonic defence.

Prosecutors argued jealousy; defence presented Glatzel’s prior symptoms: visions, levitation, animal voices. Warrens’ involvement added intrigue.

Johnson served five years. Medical experts cited dissociation, but unverified home videos keep supernatural claims alive.

8. Latoya Ammons (2011, Indiana, USA)

Single mother Latoya Ammons reported her three children possessed: walking backwards up walls (witnessed by a DCS nurse), head-butting walls leaving marks, and levitating. Her 12-year-old son growled with superhuman strength.

Priests performed multiple exorcisms; hospital staff and police verified bruises. Ammons approved for custody return post-rites.

Child services reports documented events, baffling officials. Sceptics invoke suggestion, but official logs challenge purely psychological dismissals.

9. The Possession of Julia (1970s, USA)

“Julia” (pseudonym from Malachi Martin’s Hostage to the Devil) was a Manhattan socialite allegedly possessed after occult dalliances. She levitated, spoke ancient languages, and exuded aversion to faith objects during exorcism by Father Martin.

Witnesses included doctors noting physical anomalies. Controversy stems from Martin’s sole authorship, lacking corroboration, versus detailed symptoms defying hysteria labels.

10. The Lou Sheehan Case (1980s, Connecticut, USA)

11-year-old Lou exhibited violent seizures, scratches appearing spontaneously, and speaking unknown tongues after playing with a Ouija board. Warrens oversaw his exorcism, reporting levitation and object assaults.

Audio exists of demonic voices. Sceptics question Warrens’ motives, but family testimonies persist, linking to their Discovery Channel series.

Conclusion

These 10 cases, spanning a century, reveal exorcism’s dual role as salvation and peril. From Roland Doe’s Jesuit diary to Ammons’ DCS files, evidence tantalises yet eludes consensus—medical science offers diagnoses like epilepsy or schizophrenia, yet unexplained elements like xenoglossy and levitation persist. They remind us that the line between mind, spirit, and malevolence remains blurred, urging critical examination over dismissal.

In an era of advancing neuroscience, these controversies endure, challenging us to confront the unknown with both rigour and humility. What do they reveal about human frailty, faith’s power, or forces beyond? The debate rages on.
