Sadistic offenders are often described as individuals who are forensically aware, who carefully plan their offenses, and preselect the location of their crime. Despite this emphasis on strategies to avoid police detection, no study has specifically examined whether this behavior or trait was specific to sadistic offenders. Utilizing a sample of 350 cases of sexual homicide from Canada, sadistic sexual homicide offenders (SHOs) are compared with nonsadistic SHOs on their investigative awareness. Results from logistic regression analyses show that sadistic SHOs are more likely to use various precautions to avoid detection and select a deserted location, in comparison with nonsadistic offenders. In addition, sadistic SHOs, despite having a lesser time to body recovery than nonsadistic offenders, are more likely to see their case remain unsolved. Implications for the assessment of sexual sadism as well as for the police investigations will be discussed.
施虐型犯罪者通常被描述为具有法医意识、精心策划犯罪并预先选择犯罪地点的人。尽管强调了避免被警方发现的策略，但尚无研究专门考察这种行为或特征是否为施虐型犯罪者所特有。利用来自加拿大的350起性杀人案件样本，对施虐型性杀人犯罪者（SHOs）和非施虐型SHOs的调查意识进行了比较。逻辑回归分析结果表明，与非施虐型犯罪者相比，施虐型SHOs更有可能采取各种预防措施来避免被发现，并选择一个偏僻的地点。此外，尽管施虐型SHOs在尸体被发现前的时间比非施虐型犯罪者短，但他们的案件更有可能未得到解决。将讨论对性施虐的评估以及对警方调查的影响。
