Erotophonophilia is called Lust Murder. Basically, a murder which is a consequence of lust is called erotophonophilia. According to Arrigo and Purcell, this is a type of murder driven by clear and apparent sadistic and sexually motivated behavior. This type of murder involves a mutilating attack, such as the displacement of the breasts, rectum, or genitals from the victim’s body. One of the common patterns of this murder is stabbing the genitalia with a sharp object. Both lust and killing are integral parts of erotophonophilia.
Hickey claims that the killers show a development of heinous brutality, growing more ruthless and sadistic with each murder. In their minds, erotophonophiliacs create a violently sexualized connection that they have frequently practiced while masturbating. At first, the murderers may experience harmless paraphilia, but as their fancies and daydreams grow to become more violent, the intensity, frequency, and duration of the paraphilic enticement also keep going up. In fact, in order to achieve climax, the paraphilic dream must be acted upon with increasing levels of sadistic deviance and sexualized violence. These criminals get a thrilling rush of sensual pleasure and satisfaction from their deeds. They act rather impulsively and find it difficult to leave their imaginary world. In this imaginary world, they feel overpowered, and to meet their expectation and extreme orgasm, they do all the heinous activities.
The reason behind this is pretty similar to the reason behind a serial killer. Researchers suggest that the traumatic pre-adolescent period, the environment in the family, the relationship among the family members, lost childhood, and lack of support from family all these trigger this. Social isolation and compulsive masturbation are one of major factors behind this. According to Douglas, Burgess, & Ressler, the development toward this started before the age of 5 or 6. Normally this type of murderers reached their peak in the late 20s.
