Forensic experts will carry out tests on bones found in a house believed to have been the summer retreat of former Paraguayan military ruler Gen Alfredo Stroessner.
Squatters came across the bones when they occupied the property near the city of Ciudad del Este last week. The remains were found on Wednesday by squatters who were searching the property for buried treasure after they had heard it belonged to the Stroessner family.
The bones were found under a bathroom and are thought to have belonged to four people.
Gen Stroessner ruled Paraguay from 1954 to 1989. Stroessner was deposed in a coup in 1989 carried out by another general, Andrés Rodríguez. After being ousted from power, he took refuge in Brazil, where he died in 2006.
During his rule, 459 people were killed or disappeared, according to the commission for historical memory.
Sources in Paraguay said that the house most likely was used as a torture centre, and rumours about it had been circulating for a while so much so that it was dubbed the “house of horrors”.
