Charles Whitehorn, Brown’s cousin, was discovered shot to death near Pawhuska the same day. Two months later, Lizzie Q. Kyle, who had rights for herself and had inherited the rights from her late husband and two daughters, was murdered.
On February 6, 1923, Henry Roan, another cousin of Brown, was found in his car on the Osage Reservation, dead from a shot in the head. Hale fraudulently arranged to make himself the beneficiary of Roan’s $25,000 life insurance policy.
On March 10, 1923, a bomb destroyed the Fairfax home of Brown’s sister Rita Smith, killing her and Nettie Brookshire. Smith’s husband, Bill, died four days later from injuries sustained in the blast.
On June 28, 1923, George Bigheart went to an Oklahoma City hospital after drinking poisoned whiskey. He called attorney William “W.W.” Watkins Vaughan of Pawhuska, asking him to come to the hospital as soon as possible for an urgent meeting, which he did.
Bigheart said he knew who was behind the murders and had incriminating documents proving his claim.
After the meeting, Vaughan boarded a train that night to return to Pawhuska and vanished. Found with his skull crushed, he lay beside the railroad tracks south of Pawhuska.
Bigheart died that same morning.
