Relatives of dozens of slain Colombians sued [Drummond] in federal court Thursday, accusing it of making millions of dollars in payments to a paramilitary group that sowed terror in the South American country. The suit said 67 victims of the United Self-Defense Forces of Colombia, also known as AUC, included unionists, farmworkers and others. It claimed the rightwing group received payments from operatives for Drummond allegedly to assassinate top union leaders and protect the company's large coal mine and railroad in Colombia. The lawsuit is much broader than one filed in March by the children of three slain Colombian union leaders against Drummond Co. Inc... A similar lawsuit ended in 2007 with a verdict for Drummond, which has repeatedly denied any connection with the Colombian violence.
