Marques...has accused the generals of being behind torture and killings committed by soldiers as well as by private security forces hired to protect diamond concessions in the northeastern Lundas region. He has singled out the Cuango Mining Society [in his lawsuit], a consortium that includes a company called Lumanhe, in which he says the generals have a stake...Once the investigation is complete, prosecutors will decide whether to bring the case to trial...Marques said four of the 10 victims named in the case had given testimony.
