Private investigator Sam Brower's chilling expose of Warren Jeffs' FLDS cult uncovers shocking child abuse and polygamy. Endorsed by Jon Krakauer and adapted into a 93%-rated Sundance documentary, this seven-year investigation helped convict America's most notorious cult leader. What dark secrets remain hidden?
Sam Brower, author of Prophet’s Prey, is a seasoned private investigator and leading authority on extremist religious groups, renowned for his relentless pursuit of justice against Warren Jeffs and the Fundamentalist Church of Jesus Christ of Latter-Day Saints (FLDS). A lifelong Mormon raised in mainstream LDS teachings, Brower’s seven-year investigation into the FLDS’s criminal operations—including child abuse, polygamy, and financial fraud—directly contributed to Jeffs’ 2011 conviction and life sentence.
His book, a cornerstone of true crime and investigative nonfiction, blends firsthand accounts with meticulous research to expose the sect’s secretive practices, offering rare insights from his dual perspective as an investigator and faith community insider.
Brower’s expertise has been featured in documentaries like Keep Sweet: Pray and Obey (Netflix) and Prophet’s Prey (Showtime), cementing his role as a pivotal figure in dismantling the FLDS hierarchy. Based in Cedar City, Utah, he remains an advocate for survivors of religious exploitation. Prophet’s Prey has been widely cited in academic and legal circles, praised for its unflinching examination of cult dynamics, and inspired broader cultural scrutiny of fringe religious movements.
Prophet's Prey chronicles private investigator Sam Brower’s seven-year probe into Warren Jeffs and the FLDS Church, exposing systemic child abuse, polygamy, and financial crimes. The book details Brower’s efforts to dismantle Jeffs’ authoritarian control, including unearthing Jeffs’ hidden journal, which revealed his justification for underage marriages and delusional religious mandates.
True crime enthusiasts, readers interested in religious extremism, and legal professionals will find this book gripping. It offers a firsthand account of dismantling a dangerous cult and explores themes of power abuse, making it valuable for those studying manipulative leadership or advocating for victims of systemic abuse.
Yes—Brower’s insider perspective and meticulous documentation of Jeffs’ crimes provide a chilling yet vital exposé. The narrative blends investigative rigor with human stories, making it both educational and emotionally impactful for understanding the complexities of prosecuting religiously shielded crimes.
Brower tracked FLDS financial networks, gathered victim testimonies, and collaborated with law enforcement. His breakthrough came from locating Jeffs’ hidden journal in an underground vault, which provided evidence of child marriages and Jeffs’ self-proclaimed prophetic authority.
Unlike Jon Krakauer’s Under the Banner of Heaven, which examines broader Mormon fundamentalism, Brower’s book focuses on Jeffs’ criminal empire and the painstaking investigation that toppled him, offering a procedural angle to the FLDS narrative.
Some reviewers note the graphic descriptions of abuse could be triggering. Others highlight Brower’s outsider perspective, which—while thorough—lacks firsthand accounts from FLDS women who endured Jeffs’ regime.
The book remains a cautionary tale about unchecked religious authority and systemic child abuse, issues still prevalent in extremist groups worldwide. Its insights into legal strategies against powerful institutions make it a resource for activists and policymakers.
Jeffs was sentenced to life in prison for child sexual assault in 2011. The case spurred reforms in prosecuting polygamist groups and increased scrutiny on isolated religious communities.
As a Mormon-raised private investigator, Brower understood FLDS theology but rejected its extremism. This dual perspective helped him gain informants’ trust while maintaining objectivity about the sect’s crimes.
Brower discovered Jeffs’ personal priesthood journal in a buried vault, containing explicit directives for underage marriages and self-aggrandizing prophecies. This journal became crucial evidence in court.

A frail man in prison stripes shuffles across a frozen airport tarmac, shackled and guarded by a Texas Ranger whose silver star badge catches the November light. He looks harmless-emaciated, unassuming, broken. Yet this man commanded the absolute devotion of 10,000 souls who believed his every utterance came directly from God. Warren Jeffs didn't just lead a church; he constructed an entire parallel universe where constitutional rights dissolved at the border, where children were currency, and where questioning authority could mean eternal damnation-or worse. What happens when religious freedom becomes a shield for systematic abuse? When faith transforms into a weapon wielded by a single man against thousands? The story of the Fundamentalist Church of Jesus Christ of Latter-Day Saints isn't just about one dangerous cult-it's a disturbing reminder that totalitarian control can flourish in America's backyard, hidden behind the language of divine revelation.
