The Conjuring: The Devil Made Me Do It’s character Arne Cheyenne Johnson is based on a real-life person whose story continues long after the end of the movie. The 2021 movie, which was the third installment in the flagshipConjuringfranchise and the seventh in the overall universe, is the closest the franchise has come to a true crime adaptation, as it concerned a real-life murder where the perpetrator claimed innocence due to a case of demonic possession.
In general,theConjuringUniverse moviesare either based on or inspired by the case files of real-life paranormal investigators Ed and Lorraine Warren. The married couple, a demonologist and an alleged clairvoyant respectively, are among the best known figures in paranormal history and were involved in other prominent cases including that of the haunted doll Annabelle and The Amityville Horror. Whilethe majority of their claims have been widely discredited over the years, the lurid stories at the center of their cases formed the spine of what is now the highest-grossing horror movie franchise of all time.

The Conjuring 3’s Real Arne Cheyenne Johnson Killed His Landlord In 1981
Details Of The Murder Were Changed For The Movie
TheConjuring 3castcentered Ruairi O’Connor as Arne Cheyenne Johnson, one of several real-life figures who were included in the story’s retelling of his murder trial. Although the movie fictionalized many elements of the case, it is true thatthe real Johnson killed his landlord in 1981. The killing took place after the victim, Alan Bono, drunkenly grabbed the nine-year-old cousin of Debbie Glatzel, Johnson’s fiancée. Johnson proceeded to stab Bono multiple times with a pocket knife, and when he was taken in by the police he claimed not to remember what had happened.
The landlord, renamed Bruno, was played by Ronnie Gene Blevins inThe Conjuring 3, while Debbie Glatzel was portrayed by Sarah Catherine Hook.

Ed and Lorraine Warren entered Johnson’s orbit before the murder was committed when it was suspected that Debbie’s 12-year-old brother David Glatzel was possessed by a demon. The story, which is contained in the 1983 Gerald Brittle bookThe Devil in Connecticut, goes that during an exorcism the entity transferred itself into the body of Arne. The Warrens attested to this fact and at Johnson’s trial for the murder,the plea was Not Guilty by Virtue of Possession, an unusual circumstance that led to a major media circus at the time.
Arne Cheyenne Johnson’s Murder Conviction Explained (Despite The Demonic Possession Defense)
Johnson Was Convicted Of First-Degree Manslaughter
The trial depicted in the2021 horror moviebegan on July 06, 2025 at the Superior Court in Danbury, Connecticut. The judge, Robert Callahan, quicklyrejected the Not Guilty by Virtue of Possession. However, in the light of the evidence that Bono was intoxicated and upset before he was killed, the plea was altered to that of self-defense.
This new plea resulted in Arne Cheyenne Johnson beingconvicted of first-degree manslaughter on November 24. The jury, which deliberated for a period of three days and fifteen hours, was instructed not to consider the demonic possession plea as part of their decision. Johnson’s sentencing took place just under a month later, on December 18, resulting in a relatively swift turnaround for a murder trial, considering the fact that nobody was contesting the assertion that Johnson had stabbed Bono in the first place.

First-degree manslaughter, which is a class A felony, is legally described in the United States as a case where the perpetrator either “recklessly causes the death of another person” or causes the death of an unborn child by inflicting injury on the person carrying that child.
