Joseph Yablonski

Joseph Albert "Jock" Yablonski (March 3, 1910 – December 31, 1969) was an American labor leader in the United Mine Workers in the 1950s and 1960s known for seeking reform in the union and better working conditions for miners. In 1969 he challenged Tony Boyle for the presidency of the international union and was defeated. He asked for a Department of Labor (DOL) investigation, charging a fraudulent election. In addition, Yablonski filed a lawsuit against the UMWA on five different charges related to fraud. On New Year's Eve, Yablonski, his wife, and his 25-year-old daughter were murdered, fatally shot at home by three gunmen found to have been hired on orders of Tony Boyle. A total of seven persons were convicted of murder and conspiracy to commit murder; two of the assassins were sentenced to death for first-degree murder. DOL completed its investigation, aided by the FBI, and won a suit to overturn the 1969 election by 1972. A new election was held in December of that year and a reform candidate elected, defeating Boyle. Boyle was indicted in 1973 for the three Yablonski murders; he was convicted in 1974 and received three life sentences. The union made important reforms.
