Multiple stabbing in sex-related homicides

Area of Science:

• Forensic Pathology
• Criminology
• Psychiatry

Background:

• Sexually driven homicides may stem from sexual deviation or emotional factors in non-paraphilic individuals.
• Multiple stabbing incidents are often associated with high levels of assailant affect.

Purpose of the Study:

• To investigate the relationship between multiple stabbing and sexual motives in homicide cases.
• To analyze homicide motives, methods, victim demographics, and victim-assailant relationships.

Main Methods:

• Retrospective autopsy study of 766 homicide cases.
• Classification of motives into sexual (rape, jealousy, affairs, paraphilia, etc.) and non-sexual categories.
• Analysis of stab wound counts, victim gender, and assailant relationship.

Main Results:

• Multiple stabbing (≥ 3 stab wounds) is significantly more frequent in sex-related homicides.
• The correlation between multiple stabbing and sex-related motives increases with the number of stab wounds.
• All homicides with ≥ 25 stab wounds against female victims were sex-related; jealousy was the most frequent motive.

Conclusions:

• Homicides involving multiple stabbings should be considered sex-related, especially when the victim is female.
• The frequency of stabbing correlates strongly with sexual motives in homicides.
• Understanding these links is crucial for forensic and criminal investigations.
