It’s 70 years since General Alfredo Stroessner seized power in Paraguay in a military coup. Stroessner remained in power for almost 35 years, before being toppled in 1989.More than 450 people were murdered under Stroessner's rule, with the fate of thousands more unknown. They are remembered as 'the disappeared' of Paraguay. One man has dedicated his life to finding the victims of Stroessner's dictatorship, including the remains of his own father.
