The "massacre of the São Bento farm" as it became known, took place, in the "official" version, in the early evening of January 8, 1973, in Recife, Pernambuco, Brazil. The newspapers announced a shootout between the police and a group of "subversives" who were supposed to be promoting on the site, a congress of the VPR (Popular Revolutionary Vanguard), a revolutionary group to which they belonged. Among the bodies found was that of Soledad Barrett Viedma. One of the group's members reportedly fled.

Only after 1995, after the creation in Brazil of a “Special Commission for the Recognition of the Political Dead and Missing Persons”, was it possible to “officially” confirm what many suspected and some knew. The version at the time was totally false. All those found in the farm had been arrested, in previous days, in different places.

Soledad Barrett and Pauline, another member of the group, as witnesses were violently snatched from the boutique where they worked, by five heavily armed men who claimed to be policemen. The two would have left practically dead by then. Two facts aggravate the drama of that moment. First, she was pregnant; and according to the “fugitive” member, her partner and father of her son, she was a traitor and probably participated in the group that arrested her.

Soledad Barrett Viedma, was born on January 6, 1945, in Yavevyry, Paraguay. He suffered his first exile during the civil war of 1947, when he crossed the Paraná River by boat, taken by his family, to Ituzaingó, province of Corrientes, in Argentina.

Between 1954 and 1961, back in Paraguay, he suffered all the consequences of the persecution of his father and older brothers, investigations and arrests that often took place inside his home. In 1961, she was forced to leave Paraguay for exile once again, this time for Uruguay.

In 1962, at the age of 17, of “extraordinary beauty and endowed with a special personal charm” (Mario Benedetti), Soledad became a public figure by engaging in acts of solidarity with Paraguay, in Montevideo. Having grace and a gift for dance and singing, he presented Paraguayan folklore at such events.

In July of that same year, she is kidnapped by a neo-Nazi group that, on each of her thighs, with a blade, mark her skin when reproducing the Nazi cross, the swastika, because she refused to say “Viva Hitler!” And “Below Fidel! ” Hours later it is played on a dark street at dawn. The scars remained for the rest of his life and the marks of injustice too. Even though the police recognized one of his kidnappers, they refused to arrest him and investigate him for being the son of an important person in Montevideo society.

 “These tattoos filled a certain Uruguay that lived on the moon with astonishment” wrote Mario Benedetti in a poem to pay homage to her. After this event and due to the referral given by the police, Soledad is sent, with the help of one of her brothers, to Moscow, USSR, where she studies, for a year. Upon returning, more mature and with a more defined formation, he approaches the Communist Party and starts activities in Argentina and Uruguay.

At the end of 1967, he arrived in Cuba for a period of training for armed struggle. There she meets José Maria Ferreira de Araújo, Brazilian, a member of the VPR in Brazil and who is for the same reasons as she is in Cuba. The two start a relationship, get married and from this union Ñasaindy is born.

In July 1970 José Maria returned to Brazil. In September he is arrested and dies during a torture session. In December Soledad decides to leave Cuba and return to his political activities. In December 1971, after a season between Chile and Uruguay, Soledad landed in Brazil, with the aim of strengthening and expanding VPR's actions in northeastern Brazil. After the aforementioned betrayal, she is murdered two days after her 28th birthday in 1973.

Paraguay has never claimed his remains and family members have never been able to find and rescue his body.
