Martin Bormann, Hitler’s last deputy, who vanished from the Berlin bunker and has not been seen since.

Bormann returned with Hitler to the Führerbunker in Berlin on 16 January 1945 as the Red Army approached the city. After Hitler committed suicide, Bormann and others attempted to flee Berlin on 2 May to avoid capture by the Soviets. Bormann probably committed suicide on a bridge near Lehrter station. The body was buried nearby on 8 May 1945, but was not found and confirmed as genuine until 1972. Bormann was tried in absentia by the International Military Tribunal in the Nuremberg trials of 1945 and 1946. He was convicted of war crimes and crimes against humanity and sentenced to death by hanging
Over the coming years, several organisations, including the CIA and the West German Government, attempted to locate Bormann without success.[103] The West German government in 1964 offered a reward of 100,000 Deutsche Marks for information leading to Bormann’s capture.[104] Sightings were reported at points all over the world, including Australia, Denmark, Italy, and South America.[53][105] In his autobiography, Nazi intelligence officer Reinhard Gehlen claimed that Bormann had been a Soviet spy, and that he had escaped to Moscow.[106] Nazi hunter Simon Wiesenthal believed that Bormann was living in South America.[107] The West German government declared that its hunt for Bormann was over in 1971.[108]
Interesting how many times a dead man was sighted and how many people believed he was still alive.
