Argentina activist reunited with 'wrong granddaughter'

A 92-year-old Argentine activist who spent nearly half of her life looking for her missing granddaughter will need to resume her search after a case of mistaken identity. Maria Isabel Mariani, known as Chicha, announced on Thursday that she had finally met her granddaughter. Clara Anahi Mariani Teruggi was abducted by the military in 1976. But a prosecutor working on the case said Ms Mariani had been introduced to the wrong woman. The announcement on Thursday was hailed as another triumph for the campaign group Grandmothers of the Plaza de Mayo, which was formed to reunite families with their missing children. Advertisement Even President Mauricio Macri celebrated the news on his Twitter account. But two days later DNA tests were released showing that the woman Ms Mariani met was not her missing granddaughter. "There is no genetic match between Ms Mariani and her alleged granddaughter," said prosecutor Pablo Parenti, Head of the Attorney General's Unit for Cases of Child Appropriation.
