[1] Lust murder is associated with the paraphilic term erotophonophilia, which is sexual arousal or gratification contingent on the death of a human being.
The term lust killing stems from the original work of Richard von Krafft-Ebing in his 1898 discussion of sadistic homicides.
[5] Earlier, the authors of the review reported on comparisons of offenders in the French national police database with the same conclusion.
[6] Lust murder sometimes includes activities such as removing clothing from the body, posing and propping of the body in different positions (generally sexual ones), insertion of objects into bodily orifices, cannibalism and necrophilia, as most infamously seen with the cannibalistic lust murderer Issei Sagawa.
The lust killer will have a fantasy that continues to evolve over time and becomes increasingly violent as they struggle to fulfill it.
[9] The most critical component in the psychological development of a serial killer is violent fantasy, especially in the lust murderer.
