Abstract

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.
