Kasztner also intervened on behalf of SS officers Hermann Krumey and Dieter Wisliceny, who had negotiated with him before his meetings with Eichmann. In all, "there was a total of seven interventions by Kasztner on behalf of Nazi war criminals. Three testimonies were on behalf of Becher, two were on behalf of Krumey, one was on behalf of Hans Jüttner, and there was an appeal that had the potential to deliver Wisliceny from the threat of execution in Slovakia." Wisliceny was hanged in 1948; Jüttner's 10-year prison sentence was changed to 4 years in 1949. He died in 1965; Krumey was sentenced to life imprisonment in 1969. He died in 1981; Becher died a wealthy man in 1995.
