Miguel Osvaldo Etchecolatz (born 1 May 1929) is a former senior Argentine police officer, who worked in the Buenos Aires Provincial Police during the first years of the military dictatorship. Etchecolatz was an active participant in the "anti-subversion operation" known as the National Reorganization Process. For his part in this operation, he was tried, convicted and sentenced to life imprisonment, in 2006, on charges of homicide, illegal deprivation of freedom (kidnapping), and torture. The tribunal, besides passing the sentence, stated that Etchecolatz`s crimes were "crimes against humanity in the context of the genocide that took place in Argentina". The term "genocide", introduced by the accusers, was thus employed for the first time in the official treatment of "Dirty War" crimes.
