Lucy Studey-McKiddy Breaks Her Silence After Years
For decades, Lucy Studey-McKiddy kept silent about what she witnessed during her childhood in Green Hollow. In 2022, at age 55, she finally came forward with allegations that would stun investigators and local authorities. According to reports, she claims her late father killed as many as 50 to 70 women, making him potentially one of America’s most prolific serial killers if true.
Her account is graphic and disturbing. She alleges that she was forced to help dispose of bodies, some of which her father allegedly dumped into an old well on their property. Three of his wives disappeared over the years, fueling her conviction that he was a predator. Despite her allegations, she notes her siblings refuse to believe her narrative, creating a painful family divide.
How Investigators Responded to the Explosive Claims
Lucy’s 2022 allegations triggered exhaustive law enforcement searches. Officers from the Fremont County Sheriff’s Office, FBI agents, and Iowa Division of Criminal Investigation descended on the Green Hollow property in December 2022. They brought cadaver dogs and excavation equipment to the site Lucy identified.

What Makes This Docuseries Essential True Crime Television
Despite the failed search, ‘My Killer Father’ raises haunting questions that refuse to go away. Why would Lucy make such extreme allegations if they weren’t rooted in something? How could a man live openly in a small community while allegedly harboring such a dark secret? The documentary doesn’t provide easy answers, but it explores the possibility that Studey could have ranked among America’s most prolific killers if even part of Lucy’s story is accurate.
All three episodes are available now on Paramount+, allowing viewers to form their own conclusions about this bizarre mystery. The series examines family testimony, investigative findings, and decades of rumors to piece together the truth.
Will the Green Hollow Murders Finally Be Solved?
The burning question remains: did Donald Studey commit the crimes his daughter describes, or is this a case of family trauma creating false memories and accusations? The Paramount+ docuseries presents both sides but leaves the verdict to viewers. What’s certain is that Lucy Studey-McKiddy’s decision to come forward has reignited interest in this decades-old mystery, and for the first time, millions will hear her story simultaneously.
Whether the Monster of Green Hollow will ever be proven guilty posthumously remains unclear, but ‘My Killer Father’ ensures his alleged crimes won’t be forgotten. Watch now on Paramount+ and decide for yourself.
