William J. Burns

Killers of the Flower Moon

William J. Burns was a celebrated private detective, a relentless promoter of his own legend, and, from 1921, director of the Bureau of Investigation. In the Osage murder cases, his name connected two forms of investigation: private operatives hired to pursue leads, and a federal bureau whose earlier efforts failed and whose director had himself made a career of crossing legal lines. The contrast between Burns’s reputation for finding hidden criminals and the corruption associated with his methods and leadership gives his role its defining tension.

The Making of a Detective

A former Secret Service agent, Burns succeeded the Pinkerton National Detective Agency as the country’s most celebrated private eye. His public image was carefully cultivated. He had once aspired to act, wrote pulp detective stories about his cases, and presented himself as a man ready to pursue criminals wherever they might be found. His self-mythologizing was not incidental to his profession: publicity helped make Burns a recognizable figure, celebrated by the New York Times as a detective of unusual genius and dubbed America’s Sherlock Holmes by Sir Arthur Conan Doyle.

That reputation rested on real investigative successes. Burns helped catch those responsible for the 1910 bombing of the Los Angeles Times headquarters, which killed twenty people. Yet the heroic image was only one side of his record. He had rigged juries and allegedly kidnapped a suspect; after being caught breaking into a New York law office to steal evidence, he defended such methods as necessary to expose conspiracy. The detective who cast himself as a defender of law-abiding citizens treated legal boundaries as negotiable when they obstructed an investigation.

Private Detectives in Osage County

Burns’s influence reached the Osage investigations through a professional network as well as through his reputation. Private detectives hired to investigate the deaths had often worked for the William J. Burns International Detective Agency before setting out independently. Scott Mathis assembled a team to investigate Anna Brown’s death, while the estate connected with Charles Whitehorn also hired private detectives. These operatives were not necessarily Burns’s employees at the time, and the evidence does not establish that he personally directed their inquiries; it does show that the private-investigation trade around the Osage cases had been shaped by his agency.

Burns was also an enthusiastic user of the Dictograph, a primitive listening device that could be hidden in an object such as a clock or chandelier. In the search for information about Anna’s murder, private detectives installed a device to listen to Rose Osage and her boyfriend. The surveillance produced the familiar frustrations of eavesdropping: the operatives listened to staticky voices, then lost interest in recording the innocuous details. The episode reflects an investigative culture drawn to the promise of technology, even when surveillance yielded little useful evidence. Burns’s own reputation as a pioneer of the instrument made him emblematic of that turn toward listening as a detective’s tool.

Director of the Bureau

During the Harding administration, Burns moved from private detection into federal leadership. Appointed director of the Bureau of Investigation in 1921, he bent laws and hired crooked agents, including a confidence man who sold protection and pardons to members of the underworld. The Department of Justice acquired the bitter nickname Department of Easy Virtue. Burns’s tenure placed the authority of federal law enforcement in the hands of a man already associated with investigative practices that disregarded legal limits.

The Teapot Dome scandal made that contradiction more visible. In 1924, an investigation into the bribery of the secretary of the interior by oil baron Harry Sinclair exposed abuses within the Justice Department. Burns and the attorney general used law-enforcement resources to obstruct congressional scrutiny: members of Congress were shadowed, offices were broken into, and phones were tapped. These were methods resembling the secretive techniques of private investigators, now used not to expose crime but to shield powerful interests. Burns was removed in the summer of 1924 as the administration changed and a new attorney general concluded that the bureau needed transformation.

The Osage Investigation and Its Failures

The federal bureau’s earlier involvement in the Osage murders began after the Osage Tribal Council sought Justice Department help in 1923. Burns dispatched an agent to investigate deaths that by then numbered at least twenty-four among the Osage. After only a few weeks in Osage County, the agent concluded that further investigation was useless. Other agents followed, also without success. The Osage were required to help finance the federal inquiry, and their contribution eventually reached $20,000, yet the bureau did not deliver an effective investigation under Burns’s leadership.

After J. Edgar Hoover took command, the bureau considered returning the case to state authorities rather than accepting responsibility for its failure. The account’s later reflection widens the question beyond the bureau’s administrative choices: it notes that the cases were eventually declared closed even though investigators had not connected William K. Hale to all twenty-four deaths. Burns’s presence in the story therefore belongs not only to the history of private detection or federal scandal, but also to an investigation whose failures left unresolved questions about who killed the victims the bureau had been sent to protect.

Reputation and Record

Burns’s career gathers opposing meanings around the figure of the detective. He possessed a record of significant successes and an instinct for publicity that made his name synonymous with private investigation. At the same time, his willingness to rig juries, break into a law office, and use intrusive surveillance complicates the image of the principled crime solver. As director, he carried those methods into an institution whose power magnified their consequences, and the Teapot Dome inquiry showed how investigative tools could be turned against oversight itself.

In the Osage cases, the distance between reputation and result is especially stark. Burns’s agency had helped define the private-detective profession, and former agency operatives worked on investigations commissioned by Osage estates. But when Burns dispatched federal agents to Osage County, they left without solving the murders, despite the community’s substantial financial contribution. His significance lies in that uneasy combination: the celebrated detective who fashioned himself as the answer to hidden crime, and the bureau chief whose conduct and record exposed the danger of treating investigative power as an excuse to evade the law.
