A new documentary series on Paramount+ is reigniting scrutiny of one of rural America's most unusual cases: the unresolved allegations that Donald Studey, a man who lived in Green Hollow, Iowa, was responsible for multiple unsolved murders in his community.
In "My Killer Father: The Green Hollow Murders," his daughter Lucy Studey McKiddy presents her evidence and accusations spanning three episodes. What makes this case distinctive is that the central figure—known locally as "The Monster from Green Hollow"—died in 2017 without ever being formally charged or convicted of any crime.
The case reflects a broader phenomenon in American true crime: families and communities sometimes carry decades of suspicion about alleged perpetrators, yet the formal criminal justice system never brings charges. These cold cases and unproven accusations occupy a liminal space between public suspicion and legal innocence, particularly challenging for documentary makers and families seeking closure.
Green Hollow is a small rural community in Iowa, a state in the American Midwest. The region has a history of unsolved disappearances and deaths that residents have long attributed to Studey, though law enforcement never formally connected him to specific crimes. McKiddy's documentary provides a platform for these allegations to be examined systematically, presenting her perspective on her father's activities over what she claims was a multi-decade period.
The format—a three-part series—allows for narrative depth uncommon in traditional news coverage. Paramount+, the streaming service backed by the American media corporation Paramount, has increasingly invested in true crime documentaries targeting international audiences, making cases from rural America accessible to viewers worldwide.
For international audiences, the case highlights how American investigative procedures sometimes differ from Nordic and European models. In many Scandinavian countries, for instance, missing persons cases and suspicious deaths trigger more immediate institutional responses. The Iowa case, by contrast, shows how small rural communities in the United States can experience decades of uncertainty when formal law enforcement investigations do not result in charges.
The absence of charges against Studey raises questions common in unresolved cases: Why did authorities never pursue formal charges? Were there insufficient evidence standards, jurisdictional complications, or investigative resource limitations in a rural area? These questions remain unanswered in the public record, making McKiddy's documentary an important source of information for those seeking to understand what happened.
The case also reflects evolving attitudes toward familial accountability in true crime discourse. As more documentaries feature family members accusing relatives of crimes, viewers internationally are engaging with questions about credibility, bias, and the role of personal narrative in criminal cases. McKiddy's willingness to publicly accuse her deceased father represents a significant social shift—one that would have been far less common in documentary form a generation ago.
The documentary arrives at a moment when streaming platforms are increasingly competing to acquire true crime content, particularly stories from regions with limited English-language coverage. This internationalization of American crime narratives gives global audiences insight into cases that might otherwise remain known only to small communities.
For those following the case, the series offers new details and context not previously available in English-language sources. However, viewers should note that the allegations remain unproven in any legal sense. Studey's death in 2017 means he will never face trial or be able to mount a formal defense.
The documentary does not represent an official investigation or prosecution. Rather, it documents one woman's effort to present evidence and testimony regarding her father's alleged crimes—a distinction that remains important when discussing cases involving unproven accusations.
