Paraguay’s Justice Ministry has launched an investigation after human remains were found buried beneath a home that once belonged to the former dictator Alfredo Stroessner. Stroessner was a staunch U.S. ally who seized power in 1954, ruling Paraguay for 35 years. Human rights groups say his regime murdered or disappeared hundreds of people as part of a campaign of torture and terror against political opponents. Stroessner also provided a haven to several Nazi war criminals, including Dr. Josef Mengele, known as “The Angel of Death” at Auschwitz.
