Scott Mathis’s financial guardianship of Anna Brown
Killers of the Flower MoonScott Mathis’s financial guardianship of Anna Brown joined the intimate administration of her property to a wider system of government control over Osage finances. Mathis managed Anna’s affairs through the Big Hill Trading Company, and after her death his position brought him into the first stages of the investigation. Later Bureau reports described him as compromised by William K. Hale, casting doubt on whether the guardian’s authority served the person whose assets it was supposed to protect.
Guardian and Financial System
The relationship developed within a federally imposed guardianship system. The government required the Office of Indian Affairs to assess which Osage people could manage their own trust funds. Anna and her mother, Lizzie, were among those deemed legally incompetent and required to rely on a local white guardian for financial decisions. In practice, oversight could extend to ordinary purchases, leaving the guardian with authority over both substantial assets and everyday spending.
Mathis managed the financial affairs of both Anna and Lizzie and administered Anna’s estate. He was also the owner of the Big Hill Trading Company, through which the estate was being handled. The arrangement made him more than a distant official: his business and guardianship roles placed him directly in the channels through which Anna’s money and property were managed.
The system’s classifications were not applied evenly. The account describes guardianship as generally determined by perceived blood quantum: full-blooded Indigenous people were routinely assigned guardians, while mixed-blood people rarely were. In 1921, federal restrictions further limited the annual withdrawals of Osage people who had guardians, even when they needed funds for education or medical expenses. These policies form the institutional setting of Mathis’s relationship with Anna: his authority was personal in its administration but derived from a larger structure that restricted her control over her own finances.
Estate and Early Investigation
After Anna’s body was found, those present could not identify her. Mathis, as the manager of her financial affairs, contacted Mollie Burkhart, who led a group to the creek. The party included Ernest Burkhart, Bryan Burkhart, Rita Smith, and Bill Smith, as well as others who had known Anna and people drawn by curiosity. Mathis’s contact with Mollie made his administrative connection to Anna part of the immediate family response to her death.
At Mollie’s and her family’s direction, Anna’s estate also hired private detectives. Mathis had been a juror at the inquest, and during the summer an operative hired through Mathis’s efforts asked him to identify the place where Anna’s body had been found. Mathis drove there with the operative. His roles therefore crossed from managing the estate into helping an investigator orient himself at the scene, though the available account does not establish that this act itself showed wrongdoing.
Scrutiny and Reported Connections
As the federal investigation examined the movement of oil income and headrights, agents documented allegations about Mathis and his associates. A report characterized Mathis as dishonest and as being under Hale’s influence. It also described an associate as working for Hale and the Big Hill Trading Company in dealings that exploited Osage people. The report placed Mathis within a local network of business, political, and law-enforcement connections that agents believed could shield Hale from scrutiny.
The reports require a distinction between documented roles and investigative judgments. Mathis’s ownership of the trading company, his guardianship of Anna and Lizzie, and his administration of Anna’s estate are stated as facts. The description of him as compromised by Hale is an allegation recorded by agents, not a judicial finding presented in the account. The relationship thus appears in two different registers: as a formal financial arrangement and as a point of suspicion in the investigators’ account of local influence.
Meaning and Limits of the Relationship
The probate records also showed that successive deaths were directing more Osage headrights into Mollie Burkhart’s hands. She was married to Hale’s nephew, Ernest, whom an agent described as controlled by Hale. This pattern intensified investigators’ attention to the way estates and inherited interests moved after deaths, but the evidence here does not establish that Mathis directed those transfers or that his guardianship of Anna caused them.
Later reporting broadened the concerns around guardianship beyond Mathis. Investigators described other guardians and officials as participating in, or benefiting from, a system of exploitation; a government study estimated that guardians had stolen at least eight million dollars from restricted accounts before 1925. Mathis was also recorded as having served as guardian to several other Osage people, including one who died. These details place his work within a larger and consequential institution without proving that every abuse attributed to guardians applied to him personally.
The relationship’s significance lies in this tension. Mathis had formal responsibility for Anna’s finances and estate, and his access helped shape the initial response after her death. At the same time, the structure that empowered him had already deprived Anna of ordinary financial independence, while investigators later suspected that Mathis’s business position was entangled with Hale’s influence. The account leaves the precise extent of Mathis’s participation unresolved, but makes clear why a guardian’s authority became a subject of scrutiny rather than an uncomplicated form of protection.
