which should have been destroyed; and UMWA had violated its fiduciary duties by spending union funds on Boyle's reelection. These charges and their resolution are outlined in the civil case Kenneth J. Yablonski and Joseph A. Yablonski v. United Mine Workers of America et al., 466 F.2d 424 (August 3, 1972), which his sons carried to the end. Murder On December 31, 1969, three hitmen fatally shot Yablonski, his wife Margaret, and his 25-year-old daughter Charlotte, as they slept in the Yablonski home in Clarksville, Pennsylvania. The bodies were discovered on January 5, 1970, by one of Yablonski's sons, Kenneth. An investigation found that the killings had been ordered by Boyle, who had demanded Yablonski's death on June 23, 1969, after a meeting with Yablonski at UMWA headquarters degenerated into a shouting match. In September 1969, UMWA executive council member Albert Pass received $20,000 from Boyle (who had embezzled the money from union funds) to hire gunmen to kill Yablonski. He hired Paul Eugene Gilly (September 5, 1932 – July 6, 2021), an out-of-work house painter and son-in-law of Silous Huddleston, a minor UMWA official, and two drifters, Aubran Wayne “Buddy” Martin (May 7, 1948 – March 12, 1991) and Claude Edward Vealey (July 9, 1943 – January 31, 1999). The murder was ordered postponed until after the election, however, to avoid suspicion falling on Boyle. After three aborted attempts to murder Yablonski, the killers completed the assassinations, deciding to kill everyone in the house. They left so many fingerprints behind that the police identified and captured them within three days. A few hours after Yablonski's funeral, several of the miners who had supported Yablonski met in the basement of the church where the memorial service was held. They met with attorney Joseph Rauh and drew up plans to establish a reform caucus within the United Mine Workers. The day after the bodies of the Yablonskis were discovered, 20,000 miners in West Virginia walked off the job in a one-day strike, protesting against Boyle, who they believed was responsible for the murders. Aftermath of Yablonski's murder On January 8, 1970, Yablonski's attorney waived the right to further internal review of the election by the union and requested an immediate investigation by DOL of the 1969 union presidential election. On January 17, 1972, the United States Supreme Court granted Mike Trbovich, a 51-year-old coal mine shuttle car operator and union member
