The 2023 investigation into Lucy Studey’s claims that her father, Donald Dean Studey, was a prolific serial killer concluded with the Iowa Division of Criminal Investigation (DCI) finding no evidence of human remains on the family property in Thurman, Iowa. Despite exhaustive excavations and the use of specialized forensic teams in early 2023, the case remains inactive due to a lack of physical proof.
The Genesis of the Allegations against Donald Dean Studey
The case of Donald Dean Studey captured global attention in late 2022 and early 2023, following a series of explosive reports suggesting that a rural Iowa man might have been one of the most prolific serial killers in American history. The source of these allegations was his daughter, Lucy Studey. For decades, Lucy claimed that her father had murdered between 50 and 70 women over a 30-year period, forcing his children to help dispose of the bodies in a 100-foot well and various shallow graves on their property.
Donald Studey died in 2013 at the age of 75, long before the allegations reached a fever pitch in the media. According to Lucy, the victims were primarily sex workers or transient women from the Omaha area who were lured to the Thurman property. She described a gruesome routine involving the use of a wheelbarrow to transport bodies and the application of lye and dirt to accelerate decomposition and mask the scent.
The initial 2022 interest was piqued when Fremont County Sheriff Kevin Aistrope brought cadaver dogs to the property. The dogs, trained to detect the scent of human decomposition, signaled at several locations, including the site of the old well. This provided the necessary "probable cause" in the court of public opinion—and eventually for state authorities—to initiate a more rigorous forensic examination in early 2023.
The 2023 Excavation and Forensic Investigation
The most significant update regarding Lucy Studey occurred in January 2023. Following months of tension between local law enforcement, the Iowa Division of Criminal Investigation (DCI), and the FBI, a full-scale search of the Studey property was conducted. This operation was designed to provide a definitive answer to the claims that had polarized the local community and true crime followers worldwide.
The Search Process
The investigation involved a multi-agency effort. The DCI, supported by the FBI’s Evidence Response Team and forensic anthropologists from the University of Nebraska, focused on the areas Lucy Studey had specifically identified. The process was methodical:
- Ground-Penetrating Radar (GPR): Before digging, experts used GPR to identify soil disturbances that might indicate burial pits or the exact location of the decommissioned well.
- Excavation: Heavy machinery was used to remove layers of earth at the sites where cadaver dogs had previously alerted.
- Sifting and Analysis: Forensic teams manually inspected the soil for bone fragments, clothing, or personal effects.
- Well Inspection: The 90-to-100-foot well, which Lucy claimed was the primary dumping ground, was a central focus of the 2023 dig.
The Findings (or Lack Thereof)
In a detailed statement released after the January 2023 operation, the Iowa DCI announced that the search had yielded no human remains. Investigators found some animal bones, which is common on rural farmstead properties, but nothing to suggest a mass grave or a single human burial.
The DCI’s conclusion was stark: the evidence did not support the allegations. While Lucy Studey maintained her story, the physical reality of the site—after being subjected to modern forensic techniques—did not align with her descriptions of dozens of bodies buried in the soil.
Analyzing the Conflict: Why the Cadaver Dogs Alerted
One of the most perplexing aspects of the 2023 update was the discrepancy between the behavior of the cadaver dogs in late 2022 and the negative results of the 2023 excavation. In the initial phases, multiple independent cadaver dog handlers reported that their dogs "alerted" (showed a specific behavior indicating the scent of human remains) in several spots on the Studey land.
There are several scientific explanations for why this might occur without the presence of a body:
- Residual Scents: Dogs can detect the scent of decomposition that has traveled through soil or groundwater from a different location, or from historical remains that are no longer physically present.
- False Positives: Environmental factors, such as decomposing animal matter or even certain types of fungi, can sometimes trigger a response in less-experienced or highly-stressed dogs.
- Depth and Deterioration: Some proponents of Lucy’s story argued that if the bodies were buried deep enough or treated with enough lye, the remains might have disintegrated beyond the point of detection by standard excavation, though forensic anthropologists generally find this unlikely.
The DCI maintained that while the dog alerts were enough to justify a search, they were not "proof" of a crime. The 2023 findings prioritized physical evidence over the behavioral signals of the canines.
The Family Divide: Lucy vs. Susan Studey
The credibility of the 2023 update was often viewed through the lens of a fractured family. While Lucy Studey was the primary whistleblower, her older sister, Susan Studey, remained a staunch defender of their father’s reputation.
Susan Studey consistently refuted Lucy’s claims, stating that while their father was "cranky" and "difficult," he was not a serial killer. She argued that Lucy had a history of fabrications and that the family property was never a site of mass murder. This internal conflict created a "he said, she said" dynamic that complicated the public's perception of the case.
From a psychological perspective, this case highlighted the complexities of recovered memories and family trauma. Lucy insisted that her memories were vivid and consistent since childhood. Susan insisted that such events would have been impossible to hide in a small house with multiple children. As of 2026, this rift remains unhealed, with each sister holding firmly to their version of the past.

| Case Status | State and Local Law Enforcement | Classified as inactive/closed pending new evidence. |
The Role of Media and "True Crime" Viralism
The 2023 update cannot be fully understood without acknowledging the role of digital media. The story originally gained traction through Newsweek and subsequently went viral on platforms like TikTok and YouTube. This "viral" status put immense pressure on the Fremont County Sheriff's Office and the Iowa DCI to provide answers.
The phenomenon of "crowdsourced" investigation led to many amateur sleuths visiting Thurman, Iowa, and theorizing about the case. However, as the 2023 forensic results showed, the excitement generated by true crime media often outpaces the slow, meticulous, and often disappointing reality of forensic science. The 2023 update served as a sobering reminder that alerts from dogs and decades-old memories require physical corroboration to stand up in a legal or scientific context.
Procedural Hurdles and Legal Realities
For a case of this magnitude to proceed to a criminal trial, the "corpus delicti" (the body of the crime) must be established. In 2023, the DCI faced the reality that without a body, a weapon, or a confession, there was no legal path forward.
Donald Dean Studey was a man with a criminal record, but it was largely composed of petty crimes and a history of volatility, not the high-level organization required to hide 50 to 70 murders. Investigators also cross-referenced "Missing Persons" reports from the 1970s and 1980s in the Omaha and Council Bluffs area. While many women went missing during that era, no direct links were found between those cold cases and the Studey property in Thurman.
Current Status (2026 Perspective)
As of 2026, the investigation into the claims against Donald Dean Studey is considered a closed chapter for Iowa state authorities. While the Fremont County Sheriff’s Office initially showed more openness to Lucy's claims, the definitive negative results of the 2023 DCI/FBI dig have left law enforcement with no actionable leads.
The property has not been subjected to further state-funded excavations. Lucy Studey has occasionally appeared in documentaries or interviews, continuing to advocate for further digging, suggesting that the investigators "didn't look in the right place" or "didn't go deep enough." However, without private funding or new, verifiable evidence, the site is unlikely to be revisited by forensic teams.
Frequently Asked Questions
Did they ever find anything in the well?
No. Despite Lucy Studey's claims that the well was filled with bodies, the 2023 excavation by the FBI and DCI found no human remains. They did find various debris and animal bones, but nothing indicating a human burial site.
Is Lucy Studey still sticking to her story?
Yes. Following the 2023 results, Lucy Studey has not retracted her allegations. She remains adamant that her father was a serial killer and has expressed frustration with the way the state-led investigation was conducted.
Why did the cadaver dogs alert if nothing was there?
Cadaver dogs are highly sensitive, but they are not infallible. They can alert to "residual odor" from human remains that were once there but have moved (due to water or soil shifting), or they can occasionally give false positives due to animal remains, deep-seated organic decomposition, or handler influence.
Was Donald Studey ever a suspect in other murders while he was alive?
Donald Studey had various run-ins with the law and was known to be a violent and difficult individual, but he was never a primary suspect in any serial murder investigations during his lifetime. The allegations of him being a serial killer only gained major traction posthumously through his daughter.
Can the investigation be reopened?
In the American legal system, a cold case can be reopened if "new and compelling" evidence is discovered. However, after the exhaustive search in 2023 failed to produce physical evidence, it would likely require a confession from an accomplice or the accidental discovery of remains by a third party to trigger a new official investigation.
Final Recommendation for Researchers and Interested Parties
If you are following the Lucy Studey case, it is important to distinguish between witness testimony and forensic evidence. While Lucy Studey’s testimony is harrowing and has remained relatively consistent, the 2023 update confirms that forensic science has—to date—been unable to verify any part of the physical claims. For those interested in cold cases, this serves as a significant case study in the limitations of canine alerts and the high threshold required for proving historical crimes in the absence of a crime scene. No further travel to the Thurman area is recommended, as the property is private and state authorities have concluded their on-site assessments.
