, Rita Smith, and William Vaughan In the early 1920s, eighteen
Osage and three non-Osage people in Osage County were reported murdered within a short period of time.
Colorado newspapers reported the murders as the "Reign of Terror" on the Osage reservation. Some murders seemed associated with several members of one family. On May 27, 1921, local hunters discovered the decomposing body of 36-year-old Anna Brown in a remote ravine of Osage County. Unable to find the killer, local authorities ruled her death as accidental because of alcohol poisoning and put the case aside. An autopsy revealed that the cause of death was not alcohol, but a bullet fired into the back of her head. Brown was divorced, so
probate awarded her estate to her mother, Lizzie Q. Kyle. Morrison, 38, was killed in a shootout with police on May 25, 1937. By that time, Lizzie had
headrights for herself and had inherited the headrights from her late Osage husband and two daughters. Her heirs became fabulously wealthy. In 1922, the Osage approached white oilman Barney A. McBride for help. McBride traveled to Washington, D.C. to enlist the aid of the federal government in investigating the murders. On the night of his arrival at a boarding house in the capital, he received a telegram that told him to be careful. After playing billiards and exiting from a club that same evening, an assailant tied a burlap sack around McBride's head and stabbed him over twenty times. The following morning, McBride's naked body was found in a Maryland culvert. McBride's murder later made the headline of
The Washington Times newspaper on August 12, 1922. On February 6, 1923,
Henry Roan, another cousin of Brown's, also known as Henry Roan Horse, was found in his car on the Osage Reservation, dead from a shot in the head. On March 10, 1923, a bomb destroyed the
Fairfax residence of Anna's sister Rita Smith, killing Rita and her servant, Nettie Brookshire. Rita's husband, Bill Smith, sustained massive injuries from the blast and died four days later. Shortly before his death, Bill gave a statement implicating his suspected murderers and appointed his wife's estate. Later investigations revealed that the bomb contained of
nitroglycerin. Hale was Bigheart's neighbor and friend, and had recently been designated by the court as Bigheart's guardian. The hospital doctors suspected that Bigheart had ingested poisoned
whiskey. Bigheart called white attorney William Watkins "W.W." Vaughan, asking him to come to the hospital as soon as possible for an urgent meeting. Vaughan complied, and the two men met that night. Bigheart had said he had suspicions about who was behind the murders and had access to incriminating documents that would prove his claims. Vaughan boarded a train that night to return to Pawhuska. In the morning, he was missing when the
Pullman porter went to wake him. His berth on the train had not been used. Vaughan's naked body was later found with his skull crushed, beside the railroad tracks near
Pershing, about south of Pawhuska. The
Bureau of Investigation (BOI), which preceded the Federal Bureau of Investigation (FBI), sent investigators to the reservation and found a low-level market in
contract killers to kill the Osage for their wealth. In 1995, writer
Robert Allen Warrior wrote about walking through an Osage cemetery and seeing "the inordinate number of young people who died during that time." In 1925, Osage tribal elders, with the help of local law officer James Monroe Pyle, sought assistance from the BOI when local and state officials could not solve the rising number of murders. Pyle presented his evidence of murder and
conspiracy and requested an investigation. The BOI sent
Tom White to lead an investigation. Because of the numerous leads and perception that the local police were corrupt, White decided he would be the public face of the investigation, and most of the agents would work
undercover. The other agents recruited were: a former
New Mexico sheriff; a former
Texas Ranger; John Burger, who had worked on the previous investigation; Frank Smith; and John Wren, a member of the
Ute Nation who had previously been a spy for the
Mexican revolutionaries. ==Investigation==
