born on January 31, 1940
drowned on December 11, 1961
in the Spree River near the Marschall Bridge
at the sector border between Berlin-Mitte and Berlin-Tiergarten
At around 11 p.m. on December 10, 1961, Ingo Krüger took a taxi with two friends to the Spree bank at Schiffbauerdamm. He was already wearing his diving suit under his coat. A friend who monitored boat traffic on the Spree was waiting for them.
Ingo Krüger was born in Berlin-Dahlem on January 31, 1940. His father died while serving as a soldier in the Second World War. After his mother re-married, the family moved to the eastern section of the city. Ingo Krüger grew up in Niederschöneweide in the eastern district of Treptow. His stepfather worked for the East German television company and his mother was employed as a "people’s judge" in East Germany. After finishing school Ingo Krüger completed an apprenticeship as a cook and after that he worked for a state-run company that was responsible for the gastronomy of the East German government’s guest houses. The family appeared loyal to party principles and accommodating to the system, but further examination revealed that it did not cutoff its contact with relatives and friends in West Berlin. Ingo Krüger’s fiancée, Ingrid K., also lived in the other part of the city. They had met in childhood while attending the same school in Berlin-Johannisthal. The couple began dating in 1958 even though Ingrid and her mother had moved to West Berlin. His continued contact with her is what first caused Ingo Krüger trouble with his company a year before the Wall was built. Colleagues who worked as informants for the Stasi scrupulously documented his contacts to the West, inflating them into "agent activity." When Ingo Krüger was questioned, he claimed that his fiancée intended to move to East Berlin after the wedding. He also applied for his own apartment in the East.
Ingo Krüger and his fiancée were separated from one another when West Berlin was sealed off on August 13, 1961. They continued to find ways to see each other and made dates at remote areas at the edge of the city where they could exchange letters and presents through the barbed wire. But over time these meetings became more difficult to organize and Ingo Krüger was even temporarily detained once on his way to one of their meetings and was warned that he should stay away from the border. To continue seeing each other they developed a new strategy. Ingrid R. registered her permanent address with relatives in West Germany because – unlike West Berliners – West Germans were allowed to travel to East Berlin even after the Wall was built. After that she was able to visit her fiancé again. But when the couple realized that the closed border was becoming a permanent situation, Ingo Krüger began preparing his escape.
 Ingo Krüger began preparing his escape in early November and observation reports show that Stasi agents were watching his every move. His escape route was to begin in the city center and continue across the Spree River to the Reichstag building. A number of his friends helped him to prepare and his fiancée was also in on the plan. At around 11 p.m. on December 10, 1961, Ingo Krüger took a taxi with two friends to the Spree bank at Schiffbauerdamm. He was already wearing his diving suit under his coat. A friend who monitored boat traffic on the Spree was waiting for them. She advised him to enter the river beneath the Friedrichstrasse train station to avoid the East German customs boats that assisted in guarding the border. This way the boat crew would not see him. Ingo Krüger put on his scuba and entered the water. His friends stayed on the embankment and tried to keep an eye on him in the water, but they soon noticed that something had gone wrong.
Meanwhile Ingrid R. was waiting in vain on the other side of the West Berlin bank. She watched in horror as East German customs officials began searching the water with hooks and spotlights. They eventually pulled a body out of the water and onto the boat. Despite the poor visibility, Ingrid R. was certain that the body belonged to her fiancé and that his escape attempt had failed. She was still hoping that he had survived the ordeal, but according to Berlin border police reports, the 21-year-old fugitive was already dead when they retrieved him from the water near the Marschall Bridge. According to the corpse entry book of Humboldt University’s Institute of Forensic Medicine, Ingo Krüger died on December 11 at 12:10 a. m. The autopsy book registered the cause of death as "presumably death by drowning."
The East German authorities told Ingo Krüger’s parents and fellow colleagues at his work that his friends and fiancée had helped him prepare his escape and that they were responsible for his death. One of his friends was arrested for assisting "flight from the republic." Another friend was blackmailed into working with the Stasi. At the time of the funeral on December 23 at the East Berlin cemetery on Baumschulenweg, Ingrid R. still did not know what had happened to her fiancé. Letters she sent to Ingo Krüger’s mother were not answered for weeks. The terrible truth finally reached her in a roundabout way in January.  But investigations carried out in the 1990s as part of the legal prosecution of violence at the Wall and border established that he died on that December night as the consequence of a cold shock.
