 After Emil was arrested in 1933, Kristel fled to Zurich, where she studied education and psychology at the University of Zurich. She returned to Berlin in 1934, where she too worked at the car rental agency. In 1936, Emil arranged with Quaker friends in the United States for Kristel to attend Swarthmore College there. She visited Fuchs in England en route to America, where she eventually married an American communist, Robert Heineman, and settled in Cambridge, Massachusetts. She became a permanent resident in the United States in May 1938. In 1936, Kittowski and Elisabeth were arrested again, and the rental cars were impounded. Gerhard and Karin fled to Czechoslovakia. Elisabeth was released and went to live with Emil, while Kittowski, sentenced to six years, later escaped from prison and also made his way to Czechoslovakia. In August 1939, Elisabeth committed suicide by throwing herself from a train, leaving Emil to raise young Klaus.
