The Wealthiest People Per Capita in the World Were Being Murdered for Their Money.

In the early 1920s, members of the Osage Nation in Oklahoma drove Pierce-Arrow automobiles, built terra-cotta mansions, and employed white chauffeurs. Oil discovered beneath their reservation made them spectacularly wealthy—each tribal member received quarterly royalty payments that reached $3,350 by 1925 (equivalent to over $60,000 today). National newspapers called them "the richest people in the world per capita."

Then they began dying under mysterious circumstances.

Between 1921 and 1926, at least sixty Osage people were murdered—shot, poisoned, and bombed in their homes. The true death toll likely reaches into the hundreds. Local law enforcement conducted cursory investigations that went nowhere. Coroners issued convenient rulings. Private investigators hired by the Osage were themselves murdered. The conspiracy was so vast and so protected by local authorities that it required the federal government to invent modern criminal investigation just to crack it.

This is the story of the Osage Murders—also known as the "Reign of Terror"—a systematic campaign to steal oil wealth through murder that became the FBI's first major homicide case and helped transform a small investigative bureau into America's premier law enforcement agency.

Episode 174 explores how greed, systemic racism, and legal exploitation created conditions for one of the most chilling murder conspiracies in American history.

The Reign of Terror

• 1897: Oil discovered on Osage Reservation in northeastern Oklahoma
• 1906: Osage Allotment Act establishes "headrights"—equal shares of mineral wealth for each tribal member
• 1921: Guardianship system established, automatically declaring full-blood Osage "incompetent" to manage their own wealth
• May 1921: Anna Brown found murdered with bullet in back of her head
• 1923: Lizzie Q (Anna's mother) dies under suspicious circumstances; Rita and Bill Smith killed in house explosion
• March 1923: Osage Tribal Council appeals to federal government for help
• 1925: Bureau of Investigation (later FBI) takes jurisdiction; J. Edgar Hoover sends investigators
• January 1926: Ernest Burkhart confesses, implicating uncle William K. Hale as conspiracy mastermind
• October 1926: Hale convicted and sentenced to life imprisonment
• 1929: Final convictions of co-conspirators
• 1947: Hale paroled despite Osage protests

How Murder Created Modern Law Enforcement

The Osage murder investigation transformed American law enforcement. When twenty-nine-year-old J. Edgar Hoover took over the struggling Bureau of Investigation in 1924, he saw the case as an opportunity to prove federal investigative capabilities. The Bureau deployed undercover agents posing as cattlemen, insurance salesmen, and herbal medicine peddlers—techniques that became standard FBI procedure.

The investigation revealed systemic corruption in local Oklahoma authorities. County sheriffs were on Hale's payroll. Prosecutors socialized with suspects. Evidence disappeared from evidence rooms. The case demonstrated that certain crimes required federal jurisdiction when local power structures were complicit in the criminal conspiracy itself.

For the Osage Nation, the murders left devastating scars that persist today. Approximately 26% of Osage headrights remain in non-Osage hands, a direct legacy of the murder conspiracies and corrupt guardianship system. Many murder victims were never identified. Most conspirators escaped prosecution entirely.

The guardianship system—which allowed white "guardians" to steal millions from Osage accounts—operated with legal sanction. A 1924 investigation documented that guardians had stolen at least $8 million directly from Osage people in just three years. Full-blooded Osage were automatically declared "incompetent" regardless of education or business acumen, with guardians controlling purchases "as small as a tube of toothpaste."

Congress eventually reformed guardianship laws, but only after the damage was done. The case highlighted how systemic racism and legal frameworks could enable mass theft and murder while local communities looked away. As this episode explores, the most dangerous conspiracies aren't hidden in shadows—they operate in plain sight while authorities refuse to see.

Verified Historical Sources

This episode draws on extensively documented historical records, FBI case files, academic research, and eyewitness accounts:

Federal Bureau of Investigation Official Case Files

The FBI maintains comprehensive documentation of the Osage murder investigations, including original case files, agent reports, and trial transcripts. This was the Bureau's first major homicide investigation and helped establish modern investigative protocols. Available through the FBI's official history archives.

Oklahoma Historical Society - Encyclopedia of Oklahoma History

Jon D. May's definitive article "Osage Murders" provides detailed documentation of the conspiracy, trials, and aftermath, drawing on primary Oklahoma state archives and court records from Osage County. The Oklahoma Historical Society maintains extensive collections related to Osage tribal history and the Reign of Terror period.

David Grann's "Killers of the Flower Moon"

This extensively researched 2017 book brought national attention to the long-forgotten murders. Grann spent years researching FBI files, National Archives records, Osage Nation archives, guardianship records, probate files, and tribal council proceedings. The book was adapted into a major motion picture by Martin Scorsese in 2023.

National Archives - Individual Indian Guardianship Files

The National Archives at Fort Worth and Kansas City hold original guardianship records, probate files, court documents from U.S. District Court cases (including Criminal Case 5660: U.S. v. John Ramsey and William K. Hale), and secret grand jury testimony that investigated the murders. These primary documents were crucial to understanding the systematic nature of the conspiracy.

Library of Congress - Chronicling America Newspaper Collection

Contemporary newspaper coverage from the 1920s provides firsthand accounts of the murders, trials, and public reaction. Articles from The Daily Oklahoman, Tulsa World, and regional papers documented the "Reign of Terror" as it unfolded.
