Few empirical studies have been conducted that examine the phenomenon of sexual homicide, and among these studies, many have been limited by small sample size. Although interesting and informative, these studies may not be representative of the greater phenomenon of sexual murder and may be subject to sampling bias that could have significant effects on results. The current study aims to provide a descriptive analysis of the largest sample of sexual homicide cases across Canada in the past 62 years. In doing so, the study aims to examine offender and victim characteristics, victim targeting and access, and modus operandi. Findings show that cases of sexual homicide and sexual murderers included in the current study differ in many aspects from the portrait of the sexual murderer and his or her crime depicted in previous studies. The authors' results may prove useful to the police officers responsible for the investigation of these crimes.
很少有实证研究对性杀人这一现象进行考察，而且在这些研究中，许多都受到样本量小的限制。尽管这些研究有趣且信息丰富，但它们可能并不代表更广泛的性谋杀现象，可能存在抽样偏差，这可能对结果产生重大影响。本研究旨在对加拿大过去62年里最大规模的性杀人案件样本进行描述性分析。在此过程中，该研究旨在考察犯罪者和受害者的特征、受害者的目标选择和接近情况以及作案手法。研究结果表明，本研究中包含的性杀人案件和性杀人犯在许多方面与先前研究中所描绘的性杀人犯及其犯罪情况有所不同。作者的研究结果可能对负责调查这些罪行的警察有用。
