Dagmar Hagelin (September 29, 1959- presumed dead in early 1977) was an Argentine-Swedish girl who disappeared during the Dirty War on January 27, 1977 and is presumed to have been arrested by security forces in Buenos Aires, Argentina, and murdered in a case of mistaken identity. Dagmar's father, Argentine-Swedish businessman was born in Chile and he got the Argentinean citizenship later Ragnar Hagelin, has ever since worked to have the responsible people put to justice, accusing Alfredo Astiz.
It is today believed that Hagelin was a victim of mistaken identity when on January 27, 1977 she went to visit a friend in the suburbs of Buenos Aires. Her friend, who was politically active, had been arrested the night before by Alfredo Astiz's forces and had told during interrogations that another politically active friend of her would visit the next day. Hagelin, who had decided to visit her friend on a spur of the moment, was approached by the forces and shot when she tried to escape. She was taken to ESMA, a noted torture centre, where she was later killed. Hagelin was 17 years old at the time of her death.
