Oil Made Osage Families Wealthy. Then the Murders Began.
By Elias Smith | The Native Tales
In 1921, an Osage woman named Anna Brown was found dead in a ravine in Oklahoma.
Her death would become part of one of the most disturbing criminal conspiracies in American history.
The motive was not an ordinary robbery. Investigators eventually uncovered a plot involving inheritance, oil royalties and people close to the victims.
Oil Beneath Osage Land
The Osage Nation had purchased land in present-day Oklahoma during the nineteenth century after being forced from its earlier homeland.
That land contained valuable oil deposits.
As demand for oil increased in the early twentieth century, the Osage Nation received substantial income from mineral leases.
Under the 1906 Osage Allotment Act, mineral royalties were distributed through individual shares called headrights.
These shares could provide significant income, and they could pass to heirs after a holder’s death.
That inheritance system would become central to a deadly conspiracy.
A Family Begins to Disappear
In May 1921, Anna Brown’s body was discovered in a remote ravine.
She had been shot.
Her mother, Lizzie, died under suspicious circumstances only months later.
In 1923, Anna’s cousin Henry Roan was found murdered.
That same year, an explosion destroyed the home of Anna’s sister Rita Smith and her husband Bill.
Both died as a result of the bombing, along with a young household worker.
The deaths devastated the family and intensified fear throughout the Osage community.
The Man Who Wanted the Money
Investigators eventually focused on William King Hale, a wealthy and influential cattleman known locally as the “King of the Osage Hills.”
Hale’s nephew, Ernest Burkhart, was married to Anna Brown’s sister Mollie.
As members of Mollie’s family died, their oil-related inheritance interests could increasingly benefit Ernest and, indirectly, Hale.
The investigation revealed that Hale had arranged murders to gain access to wealth and eliminate people who threatened to expose him.
The victims were targeted not because they lacked wealth, but because others wanted to control it.
An Investigation Full of Obstacles
The Osage Tribal Council sought federal help as deaths and suspicions continued.
The Bureau of Investigation, the predecessor of today’s FBI, assigned investigators to the case.
Agents faced intimidation, misleading information and a community understandably wary of outsiders.
A team led by investigator Tom White used undercover methods to gather evidence.
Some agents posed as workers and businessmen while seeking information about the killings.
Eventually, confessions and testimony helped investigators establish the roles of Hale and his associates.
What Happened to William Hale?
Hale was convicted for his role in the murder of Henry Roan and sentenced to life imprisonment.
Ernest Burkhart and other conspirators also faced criminal punishment.
But the convictions did not solve every suspicious death from that period.
Many Osage families continued to live with unanswered questions about relatives who had died.
The Osage Nation describes this period as the Reign of Terror.
A History That Must Be Remembered
The murders revealed how greed, corruption and failures to protect Native citizens could combine with devastating consequences.
They also exposed the dangers of systems that allowed outsiders to gain control over Native people’s wealth.
Today, the Osage Nation continues to preserve its history and honor those who suffered.
The story is not simply about oil or the rise of federal investigators.
It is about Osage people, their families and their right to live safely while controlling the resources belonging to their Nation.
Oil brought extraordinary wealth to Osage land. The crimes committed to seize that wealth left a painful legacy.
