Susanne apparently had a tumultuous private life. She married actor Hermann Nehlsen in 1956. Apparently that did not go well, as she tried to commit suicide twice in 1957 and was soon divorced. In 1958, she married actor Helmuth Lohner and was divorced five months later. She married Helmut a second time, which produced a child, daughter Konstanze Lohner. But a second divorce soon followed. In 1966, she married actor Kevin Hagen. Soon after, she left for Munich, Germany to visit her friend, Renate Ewert, whom she found dead. Reports were anywhere from six days to three weeks. In late 1968, she entered a private clinic in Hollywood, never to emerge, as she died on January 7, 1969. There were reports of a medical malpractice.
