Over the years, several organisations, including the CIA and the West German Government, attempted to locate Bormann without success. In 1964, the West German government offered a reward of 100,000 Deutsche Marks for information leading to Bormann's capture. Sightings were reported at points all over the world, including Australia, Denmark, Italy, and South America. In his autobiography, Nazi intelligence officer Reinhard Gehlen claimed that Bormann had been a Soviet spy, and that he had escaped to Moscow. Nazi hunter Simon Wiesenthal believed that Bormann was living in South America. The West German government declared that its hunt for Bormann was over in 1971.
