On the cold New Year's Eve of 1969, a chilling silence fell over the farmhouse of Joseph Albert 'Jock' Yablonski, a 59-year-old male and a prominent figure in the United Mine Workers of America. In the early morning hours of December 31, while he, his wife Margaret, and their 25-year-old daughter Charlotte slept in their Clarksville, Pennsylvania home, three hired assassins crept inside and brutally ended their lives.
The discovery of their bodies by one of Yablonski's sons on January 5, 1970, unraveled a dark conspiracy of union corruption and murder for hire that reached the highest levels of the UMWA.
The motive for the gruesome slayings stemmed from Yablonski's challenge to the corrupt leadership of UMWA President W. A. 'Tony' Boyle. Yablonski had run against Boyle for the union presidency, alleging widespread fraud in the election he ultimately lost. His persistence in seeking a federal investigation into the election irregularities sealed his fate. Boyle, enraged by the challenge to his authority, ordered Yablonski's death. In September 1969, a sum of $20,000, embezzled from union funds, was funneled through UMWA executive council member Albert Pass to hire the killers.
The hired gunmen were Paul Gilly, an out-of-work house painter, and two drifters, Aubran 'Buddy' Martin and Claude Vealey. On that fateful night, they cut the telephone wires and flattened the tires of the cars at the Yablonski residence before entering the home. They proceeded to shoot Charlotte twice in the head as she slept, before moving to her parents' bedroom. They then opened fire on Joseph and Margaret, killing them both.
The investigation that followed quickly led to the capture of the three assassins. Their confessions revealed the intricate plot orchestrated by the union leadership. In the ensuing trials, a total of seven individuals were convicted of murder and conspiracy. The triggermen—Gilly, Martin, and Vealey—were all found guilty of first-degree murder. Martin turned state's evidence, while Gilly and Vealey were initially sentenced to death, though their sentences were later commuted to life in prison.
The trail of conspiracy led investigators to Albert Pass, who had facilitated the payment to the hitmen, and to Paul Gilly's wife, Annette, and her father, Silous Huddleston, who were also involved in arranging the murders. Ultimately, the mastermind behind the assassinations, Tony Boyle, was indicted in 1973. He was convicted in 1974 for ordering the three murders and received three consecutive life sentences. The violent deaths of the Yablonski family exposed the deep-seated corruption within the UMWA and led to significant reforms within the union.
