Buenos Aires, Aug 5 (EFE).- Doubts about his real identity led a 36-year-old Argentine man to submit to a DNA test that showed him to be the grandson of the president of the Grandmothers of the Plaza de Mayo human rights group, the family said Tuesday.
The man was born June 26, 1978, while his mother, Laura Carlotto, was in the custody of the military regime then ruling Argentina.
Laura was killed shortly after giving birth and her body was ultimately turned over to her mother, Estela de Carlotto, but the son she bore in captivity disappeared.
Laura's brother, Guido "Kibo" Carlotto, disclosed the positive results of the DNA test.
Kibo Carlotto, human rights secretary for the province of Buenos Aires, told reporters that his nephew submitted voluntarily to DNA testing because he had doubts about his true identity.
An estimated 500 children were illegally placed with other families by the 1976-1983 military government after their parents were executed.
Under Estela de Carlotto, now 83, the Grandmothers of the Plaza de Mayo have led the search for the stolen children.
The discovery of her grandson brings to 114 the number of children tracked down.
The pregnant Laura Carlotto was arrested in November 1977 and was taken to the clandestine detention center of La Cacha in La Plata, 60 kilometers (37 miles) south of Buenos Aires.
The Argentine military regime killed as many as 30,000 people and brutalized thousands more.
Former junta leader Jorge Rafael Videla was convicted in 2012 for his part in a systematic plan to steal children from political prisoners.
The scheme, which often involved holding pregnant women until they gave birth and then executing them, was part of a "general plan of annihilation" targeting a segment of society seen by the military as subversive, the court found.
Videla subsequently died in prison.
