Is One Night in Idaho: The College Murders based on a book? Here’s everything we know

Amazon Prime Video’s new docuseries, One Night in Idaho: The College Murders reopens wounds from one of the most shocking crimes in recent American history.

Did you know its roots lie in a gripping investigative book by James Patterson and Vicky Ward? Here’s how the written word became the foundation for this powerful true crime retelling.

Early on November 13, 2022, in the quiet town of Moscow, Idaho, four students were discovered viciously murdered within their house located outside the campus. The students, Kaylee Goncalves, Madison Mogen, Ethan Chapin, and Xana Kernodle, were gifted and loved by many and were just starting their lives. This horrible incident not only provoked urgent media attention but also enraged the entire nation which led to continuous investigations for months.

Now, almost three years later, Prime Video is taking a look back at the matter with One Night in Idaho: The College Murders, a four-part docuseries that explores not only the murders and their emotional aftershocks but also the events leading up to them and the subsequent fallout.

This isn’t a documentary simply made from public information — it is a direct adaptation of the forthcoming book The Idaho Four: An American Tragedy, written by James Patterson and Vicky Ward which is set to release on July 14.

The book features more than 300 interviews and provides numerous details that contribute to the core storyline the viewers are presented with through the documentary.

Now that the suspect in the case, Bryan Kohberger, has recently pleaded guilty on July 2, 2025, and is awaiting sentencing later this month, the case is back in the news. This time, however, it is not out of social media speculation and retellings but through a potent combination of a book and a docuseries that seeks to memorialize the victims, illuminate the collective sorrow of their loss, and dissect the manner in which such a horrific crime was committed.

Here is the intersection between the book and series, and the reasons both pieces are imperative for viewers seeking a comprehensive understanding.

From page to screen: The book that inspired the series

The focal point of this multimedia study is a work by the bestselling author James Patterson alongside veteran investigative journalist Vicky Ward titled The Idaho Four: An American Tragedy, which will soon be published.

Fostered through a creative partnership built over time, the duo came together for the first time on this book, conducting dozens of interviews with families, friends, professors, community members, and police in order to give a rich, deep account of the crime. This book is more than a compilation of events; it weaves together numerous narratives to bring out the truth.

Patterson and Ward do more than report the facts. They delve into the personalities of the victims — their dreams, friendships, and routines — showing that this story is about more than a crime scene.

They also trace the journey of the alleged killer, Kohberger, exploring his academic background, digital footprint, and the forensic trail that led to his arrest. What results is a 448-page document of heartbreak and resilience that informs much of what the docuseries One Night in Idaho: The College Murders visually captures.

What the docuseries adds: First-person emotion and unfiltered voices

While the book provides a comprehensive written account, One Night in Idaho: The College Murders brings the human element to life in ways only visual media can.

The docuseries features exclusive on-camera interviews with the parents of Madison Mogen and Ethan Chapin — their first public appearance since the tragedy — and includes intimate footage and testimonials that go beyond traditional documentary framing.

It shows the toll on the Moscow community, the media frenzy, and the moment of reckoning as law enforcement finally announced charges. While much of the core research mirrors the book’s, the docuseries One Night in Idaho: The College Murders adds raw emotion and immediacy, giving viewers a direct connection to those most affected.

For anyone seeking to understand not just what happened, but why it happened, and what comes next, these two works are a must.
