George Bigheart

George Bigheart was an Osage man whose death by suspected poisoning became a junction point between the murder investigation and the financial exploitation of the Osage. Before he died, he shared critical information about the murders with his attorney, W. W. Vaughan, and sought legal help to escape government guardianship. Afterward, William K. Hale made a $6,000 claim against Bigheart’s estate with a forged note, while H. G. Burt gained control of the money inherited by Bigheart’s young daughter. The record leaves the precise circumstances of Bigheart’s death unresolved, but it shows how the investigation repeatedly led from a suspicious death to the people and institutions positioned to profit from Osage wealth.

Estate and the Struggle for Control

Bigheart was subject to the federal system that assigned white guardians to many Osage deemed unable to manage their own money. The designation could sharply restrict an adult’s control over personal funds: guardians were authorized to oversee spending, and the book describes Osage under the system needing approval even for ordinary purchases. The practice was widely criticized as discriminatory, with guardianship commonly imposed according to a person’s degree of Indigenous ancestry rather than an individual assessment of capability.

Seeking to change his status, Bigheart applied for a certificate of competency. If approved, it would end his designation as a government ward and allow him to spend his headright payments as he wished. Vaughan, who served as Bigheart’s attorney, successfully helped him file the application. Bigheart planned to pay Vaughan as much as $10,000 for this and other legal work—a substantial sum, equivalent in the book’s account to nearly $140,000 today. The effort was more than a procedural matter: the certificate offered a way to reclaim authority over money otherwise controlled through a system that left Osage vulnerable to the decisions of appointed guardians.

Information Shared with Vaughan

Bigheart’s connection to Vaughan extended beyond the legal work. Before Bigheart died, he disclosed critical information about the murders to Vaughan. That disclosure placed Vaughan in possession of knowledge relevant to the investigation and helps explain why the two men’s deaths became linked in the book’s reconstruction of events. Bigheart died after being taken to a hospital in Oklahoma City with suspected poisoning; Vaughan was dead days later.

The book later traces a financial dispute between Vaughan’s widow, Rosa Vaughan, and Burt to Bigheart’s intended payment. Vaughan had expected to receive as much as $10,000 for his services, but Burt somehow collected the money. Rosa sued to recover $10,000 she said Burt owed her husband. Her claim was initially dismissed in state court, but the Oklahoma Supreme Court reversed the decision on appeal and ordered Burt to pay her $5,000 plus interest. The dispute gave the later investigation a concrete financial trail connecting Bigheart’s legal arrangements, Vaughan’s work, and Burt’s dealings.

Death, Claims, and Guardianship

Hale also asserted a claim against Bigheart’s estate after his death. Investigators learned that Hale sought $6,000 by presenting a creditor’s note that was forged. Ernest Burkhart disclosed that, before filling out the document, Hale had practiced making his handwriting resemble Bigheart’s. Witnesses had seen Hale with Bigheart shortly before Bigheart was rushed to the hospital. Together, the alleged forgery, the timing of Hale’s visit, and the claim against the estate made Bigheart’s death part of the wider inquiry into how Osage property was being taken.

Burt’s access to Bigheart’s family finances raised a separate concern. Bigheart’s fortune passed to his wife and young daughter, and his daughter was assigned a guardian: Burt. This gave Burt control over her money without making him an heir. Investigators and the later narrator knew that Burt was a close associate of Hale’s, that both men had visited Bigheart shortly before his death, and that Burt had become the guardian of several Osage, including one who had died. The arrangement placed him in a position to administer wealth left to Bigheart’s child, even as other records tied him to money Bigheart had intended for Vaughan.

Evidence and Unresolved Suspicion

The case against Burt accumulated through records that appeared ordinary in isolation. He was a banker and businessman in Pawhuska who had made money through lending to Osage at steep interest rates. His accounting practices drew questions during probate proceedings: loans said to come from his bank were issued from his personal checkbook. Burt defended the practice as the way the business had always been handled. Separately, an informant described him and Hale as close associates who had divided money obtained from Bigheart. The report did not establish precisely what that money included, and the book presents the possible connection between the reported division and the sums Burt sought to collect as a possibility, not a settled accounting.

The narrator’s archival reconstruction finds no evidence that Hale, Burt, or another white man inherited Bigheart’s fortune; it went to Bigheart’s wife and daughter. That absence did not dispel concern about access to the estate, because Burt’s guardianship gave him control over his daughter’s funds. Nor did it prove that either man had poisoned Bigheart. The account explicitly treats Burt’s possible role in Bigheart’s and Vaughan’s deaths as circumstantial. White and his agents suspected Burt, and one Bureau of Investigation report called him a murderer, but the Justice Department did not prosecute Hale for Bigheart’s killing or pursue Burt further. The suggested explanation is that the sums involved, especially if divided, offered less apparent incentive than the headrights and insurance money in other cases.

Bigheart’s significance in the narrative therefore rests not on a conclusive answer to who killed him, but on the convergence of his attempted financial independence, his disclosure to Vaughan, and the claims and guardianships that followed his death. His experience exposes the vulnerability built into a system that placed Osage funds in the hands of appointed white administrators. The records leave the murder unresolved; they make the surrounding machinery of access, control, and suspected profit unmistakable.
