In the summer of 1921, the disappearance of Eleanor and Margaret Ashcroft in Elmore County, Oklahoma, was treated as a simple missing persons case. The sisters were last seen on June 17th, walking the perimeter of their family’s property near the small town of Riverbrook. When they failed to return for supper, their father, Dr. Thomas Ashcroft, a respected physician, reported them missing.
A three-week search turned up nothing, and the case was eventually relegated to rumor and speculation. The prevailing explanation became that the sisters had voluntarily left town, perhaps for opportunities in a growing city or out west. Thomas Ashcroft himself reinforced this theory by claiming some of his daughters’ clothing was missing, suggesting they had packed. Most residents accepted this.
Yet there were inconsistencies that troubled a few observers, neither sister had withdrawn their small bank savings, no nearby train station reported selling tickets to women matching their description, and both had left uncollected mail-order packages at the post office. The family sold their property in 1923 and reportedly relocated to Arizona due to the health of Thomas’s wife, Virginia, who had been largely invisible to the community since early 1921. The case might have been forgotten entirely had it not been for a severe storm in April 1967. The storm uprooted an elm tree on the old Ashcroft property, and the owner, Mr.
Davis, discovered partial skeletal remains tangled in its roots. Forensic examination confirmed the remains belonged to an adult female, likely in her late 20s, and noted unusual markings on the cervical vertebrae consistent with possible strangulation. The discovery reopened the dormant case. Investigators found something else alongside the remains: a small metal box containing a journal.
Though most pages were destroyed by decades of exposure, several passages remained legible, and the handwriting was identified by former neighbors as belonging to Eleanor Ashcroft. Entries dated May and June 1921 described a “basement room” prepared for the sisters’ ailing mother, Virginia. Eleanor wrote of hearing sounds from below, of locked doors, and of trays of food returning untouched. A final entry dated June 15th, two days before the disappearance, read, “I found the key.
Tonight, when father leaves, Margaret and I will see for ourselves. Whatever is happening in that room must end. ”
The investigation that followed unraveled the foundation of the case. Thomas Ashcroft’s medical credentials, never questioned during his time in Riverbrook, proved impossible to verify.
The basement of the home contained a small room with a heavy door fitted with external bolt locks and walls lined with rotted padding, apparently intended to muffle sound. A former assistant recalled Thomas mixing strange compounds and becoming agitated when asked about them. Neighbors told investigators that Virginia Ashcroft had begun behaving unusually in late 1920. Thomas had explained to friends that his wife suffered from “female hysteria” and required his specialized care at home.
After February 1921, no one saw her at all, though Thomas assured the community she was recovering under his constant attention. Criminologist Dr. Rebecca Hayes, who analyzed the case in 1968, posited a disturbing scenario: that Virginia may have suffered from a legitimate condition that Thomas attempted to treat using unorthodox, possibly experimental methods. The basement room was likely a makeshift treatment facility that evolved into a prison.
The sisters, upon discovering their mother’s condition, posed a threat to Thomas’s professional standing and his freedom. Hayes suggested Thomas murdered one sister, likely Eleanor, and forced or manipulated Margaret into assistance before disposing of her as well. Investigators attempted to locate Thomas and Virginia Ashcroft but found Thomas had died in 1946 in Phoenix, Arizona. No death certificate was found for Virginia, and no record of her existed after the family left Riverbrook.
Additional evidence emerged over time. A 1965 renovation at the Riverbrook Post Office uncovered an envelope postmarked June 16th, 1921, the day before the disappearance, addressed to the Oklahoma State Medical Board with Eleanor’s name as sender. The letter itself was missing, but its existence fueled questions about what Eleanor had intended to report. In 1968, an antique dealer in Phoenix contacted authorities after purchasing the contents of a storage unit abandoned after the death of a “Thomas Johnson” in 1946.
Included was a leather medical bag containing treatment logs for a patient identified only as V. A. The entries, written by the same hand that signed Thomas Ashcroft’s 1921 statements, described a nervous condition that progressively worsened. A final page dated June 18, 1921 read simply, “All obstacles removed, treatment can now proceed without interruption.
”
The storage unit also contained photographs of a young woman taken in the southwestern United States between 1923 and 1946. Investigators believed she bore a strong resemblance to Margaret Ashcroft, raising the possibility that Margaret had survived and remained under her father’s control for decades. A crucial account emerged from a former housekeeper, Katherine Lewis, interviewed in 1962. Lewis described Thomas locking himself in the basement with Virginia for hours, and said she could hear Virginia crying and begging him to stop.
She once saw Virginia afterward looking like a ghost, barely able to walk, with strange marks on her arms. Lewis also overheard arguments between Thomas and Eleanor in the weeks before the disappearance, including Eleanor saying what he was doing “wasn’t treatment, it was torture. ”
One of the most striking leads involved an elderly woman who appeared at the Riverbrook Cemetery in 1968, placing flowers at a newly installed memorial stone for the sisters. She identified herself only as a former friend of the Ashcroft family, placed a tarnished house key beside the flowers, and left.
The groundskeeper noted her license plate, which traced to a Margaret Johnson of Amarillo, Texas. By the time investigators arrived, the house was vacant, and the woman had moved without a forwarding address. The investigation into whether she was Margaret Ashcroft was never concluded. In 2003, the Riverbrook Historical Society received an anonymous donation: a leather-bound journal and a note stating it was the “final testament of Margaret Ashcroft Johnson,” to be opened 50 years after the writer’s death.
The journal described events in harrowing detail. Margaret wrote of finding their mother strapped to a bed in the basement, barely conscious, thin, and covered in marks from injections. She described her father returning unexpectedly as the sisters attempted to free Virginia, striking Eleanor, and then forcing Margaret to help bury her sister under the elm tree. He threatened to blame Margaret for everything, and said she would suffer as their mother had.
According to the journal, Thomas forced Margaret to send postdated letters describing a fictional journey to California. He relocated Virginia to a private sanitarium in Arizona under an assumed name, where Margaret believed her mother died in 1925. Under Thomas’s control, Margaret assumed a new identity as Margaret Johnson, presented variously as his daughter, sister, or niece. After his death in 1946, she built an independent life but remained haunted by guilt and fear.
The journal’s authenticity could not be conclusively verified, though handwriting analysis showed similarities to Margaret’s known pre-1921 writing, and details aligned with evidence that was not publicly available at the time. In 1994, historian Maria Holloway published her father’s unfinished manuscript, “Forgotten Tragedies: The Lost History of Rural Oklahoma,” providing the most comprehensive account of the case to date. The case has since been cited in academic studies of historical crime and medical abuse. The property where the Ashcroft house once stood remains undeveloped, a conspicuously empty lot surrounded by modern development.
The Ashcroft case was officially closed in December 1968 due to insurmountable evidentiary challenges and the presumed death of all involved parties. Sheriff Walter Pruitt’s final report acknowledged substantial circumstantial evidence of criminal activity by Thomas Ashcroft but concluded the exact nature and extent of the crimes could not be determined. A handwritten note in the margin read, “Some doors are better left unopened. God have mercy on their souls.
