[Malignant narcissism and sexual homicide--exemplified by the Jack Unterweger case].

With the syndrome of malignant narcissism, which is characterised by narcissistic personality disorder, anti-social behaviour, sadism and a marked tendency to paranoid reactions, Kernberg (1985, 1996) describes an independent form of pathological narcissism. According to Stone (1996) this is found in many mass-murderers and serial killers. On the basis of the example of Jack Unterweger the connection between malignant narcissism and sexual offence is discussed as to psychodynamic development, personality structure and psychopathology. Unterweger, who was convicted to lifelong imprisonment in 1976 for sadistic sexual murder, became a wellknown writer in prison and was released prematurely in 1990 as the Austria case of successful rehabilitation. As stated in the sentence passed against him he killed 11 prostitutes in Europe and the USA within the next 18 months, but never pleaded guilty. Psychiatric examination revealed numerous elements of malignant narcissism and the constellation of his development and life was typical of serial offenders.
