Another chapter in my recent book Murder and Mayhem in Northeast Oklahoma https://amzn.to/3OWWt4l concerns the Osage murders, made infamous by the book Killers of the Flower Moon and the 2023 movie of the same name.
On May 27, 1921, the body of Anna Brown was found beside a road between Fairfax and Grayhorse in Osage County, Oklahoma. Brown had been shot through the head. Initial reports mentioned that, as a member of the Osage tribe, she was receiving about $1,000 per month in “oil royalties;” but the only theory of the crime local authorities could offer was that she had been the victim of highway robbery.As it turned out, Anna Brown was not the victim of highway robbery but of one of the most diabolical get-rich schemes in American history. Because of a series of land deals made with the federal government going back to the late 1800s, the Osage held the rights to one of the largest deposits of oil in the United States. To divide up the profits from the commonly owned mineral rights, a system was adopted by which each Osage member would receive an equal share of the revenue. This came to be called a headright. Private companies could lease the land and then pay a percentage of their profits into a trust fund managed by the Bureau of Indian Affairs. The BIA would then distribute payments to the holders of the headrights.
During the Oklahoma oil boom of the early 1900s, the Osage people became some of the wealthiest in the world, as members of the tribe, like Anna Brown, received payments that today would be worth hundreds of thousands of dollars per year.
Anna Brown was not the first victim of the scheme, but most of the murders occurred in the early 1920s, and her case was the first to receive much publicity. In total, at least 24 members of the Osage tribe were killed or died under mysterious circumstances during the "Reign of Terror," and some estimates place the number much higher. Most of the murders occurred in the Fairfax-Grayhorse area, and many of the victims were members of the same family, relatives of Anna.
Several people were arrested for questioning or as suspects in Anna's death, including Ernest Burkhart, who was married to Anna’s sister Mollie, but the coroner ultimately ruled that Anna had been killed by parties unknown.
The coincidence of so many members of the Osage tribe, especially members of the same family, dying so close together in time and place was too obvious to ignore, and the Bureau of Investigation (forerunner of the FBI) finally initiated an investigation. The investigative team kept encountering the names of William K. Hale and Ernest Burkhart, the same Ernest Burkhart who was married to Anna's sister Mollie and who had been arrested for questioning in Anna's death. Hale, a wealthy, prominent citizen, was Burkhart's uncle, and he was eventually identified as the mastermind behind the murders of Anna and her family. The scheme was for Burkhart to inherit all the family's wealth and then turn a large portion of it over to his uncle.
