Information on sexual homicides in China is scarce, particularly with respect to the offenders' primary motivation for the offence.
Our aim was to examine how offence characteristics of sexual murderers relate to different primary motivations.
The offender, victim, and offence characteristics of 67 sexual homicides, derived from police data of three regions and published case reports (1994-2017), were explored and compared according to offenders' primary motivation.
Heterosexual sexual homicides were committed by offenders who were mainly driven by power and control, sex, and anger, compared with slightly over half of those who motivated primarily by financial gain. Sexual murderers whose killing was mainly driven by sex, money, and anger were more likely to target strangers, whereas offenders who motivated primarily by power and control were more likely to target an intimate partner. Victim abduction was more frequently seen in offenders who were motivated predominantly by money than other motives. Relative to financial gain as primary motivation, sexual killers who were mainly driven by sex, power and control, and anger were more likely to mutilate their victim.
This study adds data to a field rarely studied anywhere and hardly at all in China. Findings may offer some help for criminal investigators who need to prioritise their investigative strategies. Once the individual is convicted and sentenced, they may help direct management and/or therapeutic strategies.
中国关于性杀人案件的信息匮乏,尤其是关于犯罪者犯罪的主要动机方面。
我们的目的是研究性杀人犯的犯罪特征与不同主要动机之间的关系。
根据三个地区的警方数据和已发表的案例报告(1994 - 2017年),对67起性杀人案件的犯罪者、受害者及犯罪特征进行探究,并按照犯罪者的主要动机进行比较。
异性性杀人案件的犯罪者主要受权力与控制、性和愤怒驱使,而主要受经济利益驱使的犯罪者略超过一半。主要受性、金钱和愤怒驱使的性杀人犯更有可能将陌生人作为目标,而主要受权力与控制驱使的犯罪者更有可能将亲密伴侣作为目标。与其他动机相比,主要受金钱驱使的犯罪者更频繁地绑架受害者。相对于以经济利益为主要动机,主要受性、权力与控制和愤怒驱使的性杀手更有可能残害受害者。
本研究为一个在其他地方很少研究、在中国几乎未被研究的领域增添了数据。研究结果可能会对需要确定调查策略优先级的刑事调查人员有所帮助。一旦犯罪者被定罪量刑,这些结果可能有助于指导管理和/或治疗策略。
