On the basis that the literature shows that most of the serial murders are committed by men and with sexual motivation, the research is a preliminary approach which aims to approach the cultural influence on the sexual motivation of serial killers. Eighty-six cases of serial murders with male perpetrators from different countries have been analyzed, com-mitted between 1900 and 2020. The variables evaluated are related to the serial offender, victimology, modus operandi, sexual motivation typology and the actions related to such classification. In indulgence countries, pre mortem sexual acts (44.20%), interference with the victim’s body (36.0%) and mutilation (27.90%) are the most common; the same occurs in restrictive countries, although in a lower percentage, with mutilation 7.0% being the only statistically significant variable (X2 = 0.034). Direct-sadistic motivation is the most present, being 52.30% in indulgence countries and 18.60% in restrictive countries, there being a significant relationship (X2 = 0.026). There is a partial influence of culture on modus operandi and sexual motivation according to the higher or lesser presence of social norms and how they influence the individual's decision making.

Keywords : Serial murder; sexual motivation; cultural influence; indulgence; restriction.
