"Coal Country Killing: A Culture, A Union, And The Murders That Changed It All, revolves around the cold-blooded 1969 assassination of United Mineworkers of America "reform candidate" Jock Yablonski, and murder of his wife and daughter in their Pennsylvania farmhouse. But driving the story are the extraordinary efforts of a tenacious special prosecutor and his "army" of investigators to bring the gunmen, the union boss who ordered the murders, and his henchmen who saw them carried out, to justice"-- Provided by publisher.
