1 Page Summary

Gregg Olsen's The Back Bedroom: A True Story of Exorcism and Murder examines how a self-proclaimed prophet named Leon Cunningham transformed his Yakima home into a private church and drew vulnerable followers into a closed world of escalating control. What began with selling televisions and radios as "distractions" and predicting the end times curdled into the belief that three-year-old Davey Weilbacher was possessed by a demon. Over fifty-nine days in 1976, the household beat the child twice daily under Leon's direction, sealing his body in the back bedroom after he died, convinced he would rise as "Seth" on the third day. The book's central thesis is that sincere faith, isolation, and unquestioned authority can make ordinary people participate in torture and conceal a death—and that the law's eventual reckoning left the deeper moral questions unresolved.

Olsen's approach is immersive and character-driven, reconstructing events through the eyes of those inside the house: Tina Cunningham, the young daughter-in-law who smuggled vodka to her mother-in-law and later testified for the prosecution; Gary Cunningham, the only household member besides Velma who refused to join the beatings; and Velma herself, whose faith shattered when she finally fled to Seattle. The narrative resists easy caricature, showing how loneliness, poverty, and a longing for belonging made Leon's promises feel like a safe place to land, and how moments that might have been warnings—a Marine father's twenty-hour drive to check on his son, burns left on stove burners, bruises on an infant's feet—were explained away by people who had already decided what was real.

The book is suited to readers of true crime, cult and coercive-control narratives, and stories about the psychology of belief under pressure. What readers gain is not simply an account of a crime but a granular view of how a group can talk itself into cruelty one small step at a time, and of the aftermath: manslaughter and assault convictions, appeals that pared sentences to roughly five years for the women and ten for Leon, and survivors like Tina who still carry the memory of a boy she insists was never possessed.

Prologue

Overview

Most of the people in that house went to prison for what they did, but one walked free. She visits, she carries a guilt that never fades, and she keeps the truth buried. The past is real, and so is the silence.

An Ash Cloud and an Expected End

Mount Saint Helens erupted in the spring of 1980, turning day to night over Yakima, which took five inches of ash. Some read God's judgment into it. For a small group in the visitors' room at the women's prison near Gig Harbor, the end they had anticipated, and killed for, had come.

The Weekly Visits

Tina Cunningham, twenty-five, drove fifteen minutes from Port Orchard nearly every week for over four years, often with her husband Gary. She came to see her mother-in-law Velma, her sister-in-law Carolyn, and two church members, Lorre Edwards and Debbie Weilbacher, all imprisoned over what happened to Debbie's son, Davey.

Smuggled Vodka and Old Guilt

She brought Velma vodka in a baby bottle hidden in a diaper bag; Velma, once a teetotaler, had become an alcoholic after believing her husband Leon's prophecy that Judgment Day was near. Tina also came out of guilt over the cramped house where they prepared for the end. Shame is like an IED in the sand: it may never go off, but it stays. Later years brought:

  • divorce
  • drug arrests
  • homelessness

Fifty years on, she said what happened in that house was real.

Key Takeaways
  • A natural disaster arriving on schedule can be taken as confirmation rather than coincidence by people already braced for the end, which is exactly how the ash over Yakima landed.
  • A prophecy that fails does not scatter the group that carried it; the ties persist in prison visiting rooms, in marriages, and in years of accumulated obligation.
  • The heaviest cost fell on people who never chose the belief, including a daughter-in-law who kept making the drive out of guilt over the crowded house where the preparations happened.
  • Vodka in a baby bottle, followed by divorce, addiction and homelessness, measures what the certainty left behind, and the participant who still calls that house real shows these movements are weighed by their wreckage rather than by whether the prediction came true.

Chapter One

Overview

A woman walks into a sheriff's office to report a death in her own home. She talks about faith and family. The police want evidence and law. Someone has to decide what to do when a man says God's word matters more than the law.

The Report

On September 19, 1976, Velma Cunningham walked into the Yakima County Sheriff's Office. She was forty-five and the mother of seven. With her was a pastor from a different church than her husband Edward Leon Cunningham's. Davey, a three-year-old, was dead in the back bedroom, she told the deputy. He had been possessed by the Devil.

The Call

Earlier she phoned Leon from a son's home near Seattle. Things were not right, she said, and God wanted her to speak to the police. Leon told her she would pay for her unbelief. He answered only to God, and the police hardly mattered.

What Came Before

The Exorcist had made possession talk familiar. The house also held Carolyn, the couple's daughter, twenty-seven; Lorre Edwards, twenty, and her son Brian, three; and Debbie Weilbacher, twenty, and her son Davey.

Fifty-nine days had passed since Davey died. By Leon's account, God had told him the Antichrist was about to return and the family needed to prepare. That preparation began in the fall of 1975.

Key Takeaways

Velma Cunningham needed a pastor from outside her husband's church to challenge Leon Cunningham's control. Leon Cunningham believed God's word outranked civil law, so the sheriff's office meant nothing to him. Nearly two months passed between the child's death and the official report. No one outside the household had checked in during that time. Other adults and children lived in the Cunningham home, so what happened there involved everyone in the house, not just one family.

Key concepts: Chapter One

Chapter One

The Report

  • Velma Cunningham reports child's death to sheriff on September 19, 1976.
  • She is accompanied by a pastor from a different church than her husband's.
  • Three-year-old Davey was dead in the back bedroom, possessed by the Devil.

Leon's Defiance

  • Leon tells Velma she will pay for her unbelief.
  • He answers only to God, not the police.
  • He believes God's word outranks civil law.

The Household Context

  • Fifty-nine days passed between Davey's death and the official report.
  • Other adults and children lived in the Cunningham home.
  • Leon claimed God told him to prepare for the Antichrist's return.

Chapter Two

Overview

Leon Cunningham turned his home into a church, and for people who felt lost, it felt like a safe place to land. But the comfort came with control. The household eased real loneliness while slowly changing what its members believed was true. The outside world grew distant, and the family's rules took over.

The Yellow House

Leon Cunningham worked at a fruit plant and preached without a formal church. He lived at 621 South Twelfth Street, near the Yakima County fairgrounds. He urged neighbors to come to his home church and be saved from eternal damnation. He warned that the end times were coming and that God had told him the Antichrist would return. Nobody accepted.

The Household

The household held Leon and Velma, their adult children, three other young women, and three children.

  • Carolyn was devoted to her father.
  • Gary, twenty-one, returned from the military with his wife, Tina, and baby, Gaspar. Leon wanted them under his roof.
  • Lorre Edwards had dated Gary at fifteen and bore their son, Brian, at seventeen. The two stayed when he joined the army in 1973.
Debbie Arrives

Debbie Bossert Weilbacher married the boy next door, David Weilbacher, on March 21, 1972. David was eighteen and serving with the marines in Vietnam when he learned by telegram that their son, Davey, had been born. Debbie asked him if he had been unfaithful. He admitted it happened once. She could not let it go. She packed up Davey and returned to Yakima to wait for the divorce.

The Home Church

Her friend Lorre invited her to the Cunninghams' home church. Lorre had used drugs and seemed lost. By fall 1975, Debbie was eating with the family and attending services that ran late into the night. She told them she had considered suicide, and the family said God would save her. At nineteen, she saw Leon and Velma as parents, and they invited her and Davey to move in.

The Prophecy

Leon's prophecy held them together: the coming terror would not touch those who believed in Christ and whose names were in the Lamb's Book of Life. The household came to see nonbelievers as zombies, the walking dead. His two weekly services multiplied tenfold over time, with gospel records, shared meals, and shared chores. Everyone had a role before the move God would signal. The same words repeated like a dripping faucet: something was coming.

Key Takeaways
  • The home church grew not by persuading skeptics but by taking in people whose own families had already failed them.
  • Leon promised rescue from the coming terror, and that promise met a deep need to belong. Obeying the group started to feel like the only sane choice.
  • The group called outsiders the living dead. That made any disagreement feel like a spiritual crisis, and leaving feel the same as damnation.
  • Leon's authority rested on repetition and readiness, not on any prediction that came true. Endless services and assigned roles kept everyone preparing for a signal that never came.

Chapter Three

Overview

A warning comes in that a child may be hurt. Every adult who could confirm it denies it. The father drives twenty hours, sees nothing he can point to, and goes home. Months pass before he learns how much was hidden.

David Weilbacher is a Marine in his early twenties, stationed in Yuma, Arizona. He gets a call from Herm Bossert, his ex-father-in-law. Herm says one of Debbie's sisters saw bruises on Davey, David's son. David trusted the sisters, but the report makes no sense. He drives twenty hours to Yakima, where Debbie and Davey have moved in with the Cunninghams.

The Visit

At the Cunninghams, David is told Debbie and Davey are not there. He goes to his former in-laws, where Debbie is staying. She is colder and evasive, and David later learned she had used drugs. She says Davey is fine, that kids fall, and that any bruises came from a playground stumble. David insists on taking Davey. Herm abruptly sides with Debbie and calls it a misunderstanding.

Aftermath

When David sees Davey, he finds no bruises. He holds Davey, wonders whether a boy belongs with his mother, and returns to Yuma the next day. Months pass before he talks to anyone. Calls fail to reach Debbie. He hears Davey's living situation is strained and that Herm and his wife want custody, while Debbie opposes them. David wonders what Debbie told Herm to change his stance.

Key Takeaways
  • A relative's warning can be real, and a parent still may not be able to prove it, especially when the other parent dodges questions and the child looks fine.
  • A grandparent who raises the alarm can later wave it off, which shows how family loyalty can make someone ignore the original warning.
  • A father who believes a son belongs with his mother can ignore direct warnings and step away from a situation that is still not resolved.
  • When a parent without custody loses contact, a custody fight among relatives can go on while the child's daily life stays hidden from the person most able to help.

Even after convictions and appeals, the story suggests that courts cannot fully resolve the question of what is owed to a child like Davey.
