In Argentina, convicted mass murderer Luciano Benjamín Menéndez has died in prison at the age of 90. Menéndez was a senior military commander nicknamed “The Hyena” during the U.S.-backed Argentine dictatorship of the 1970s and ’80s. In 2010, Menéndez was sentenced to 13 terms of life in prison for crimes including torture and murder at secret detention camps. Menéndez died without ever confessing what he did with the bodies of thousands of activists who were “disappeared” during the dictatorship.
