Most studies have focused on male sexual homicide offenders (SHOs) without testing whether sex differences exist. Accordingly, little is known about the distinctions between male and female SHOs, particularly with respect to their use of weapons in killing their victims. This study used a sample of 3,160 single-victim sexual homicide cases (3,009 male and 151 female offenders) from the U.S. Supplementary Homicide Reports database to explore sex differences in the types of murder weapons used by offenders in killing victims over the 37-year period 1976 to 2012. Findings indicated that significantly more male SHOs used personal weapons (43%) and more female SHOs used firearms (63%) in their offense commission. In general, female offenders predominantly used weapons that were physically less demanding (e.g., firearms and edged and other weapons; 89%). Different trends in the murder weapons used by male and female SHOs from different age groups were observed. Interestingly, findings showed that the type of weapon used by SHOs was in part influenced by the victims and their characteristics.
大多数研究都集中在男性性杀人罪犯（SHOs）身上，而没有检验性别差异是否存在。因此，对于男性和女性性杀人罪犯之间的区别，尤其是他们在杀害受害者时使用武器的情况，人们了解甚少。本研究使用了来自美国补充杀人报告数据库的3160起单受害者性杀人案件样本（3009名男性罪犯和151名女性罪犯），以探讨1976年至2012年这37年间罪犯在杀害受害者时所使用的谋杀武器类型上的性别差异。研究结果表明，在犯罪过程中，显著更多的男性性杀人罪犯使用个人武器（43%），而更多的女性性杀人罪犯使用枪支（63%）。总体而言，女性罪犯主要使用对体力要求较低的武器（如枪支、带刃武器和其他武器；89%）。观察到不同年龄组的男性和女性性杀人罪犯在谋杀武器使用上存在不同趋势。有趣的是，研究结果表明，性杀人罪犯使用的武器类型部分受到受害者及其特征的影响。
