“…Homicide with mutilation is rare, and it increases the difficulty experienced by criminal investigators in identifying the offender because the offender tends to remove the criminal evidence (such as a corpse). Especially in Japan, "defensive" offenders form the Other countries 3 (10) 0 (0) 1 (4) 3 (13) majority. This study identified proposed several directions for criminal investigation of mutilation homicide cases in Japan.…”

“…Therefore, the first purpose of this study is to assess whether the current sample highlights the typical demographic characteristics of offenders in alignment with previous studies. It is noteworthy that sexual homicides with criminal dismemberment differ from regular mutilation homicides in that over half of the sexual offenders assault stranger victims [12,13].…”

This study examined the offender characteristics of criminal mutilation homicides in Japan for offender profiling. The current sample (N = 108) showed that the most typical offender was a male, in his 30s (age that observed most often), one-person, and acquainted with the victim. This study highlighted that the cases of mutilation homicide differed in comparison with the regular homicide group in terms of the victimoffender (VO) relationship and the number of offenders. Furthermore, the multiple correspondence analysis classified mutilation homicides into four behavioral pattern types based on two dimensions (level of "efforts of corpse dismemberment" and "efforts of corpse disposal"). In the first type "high evidence destruction effort (n = 29)", having the greatest efforts to destroy evidence, all offenders were men. The rates of no VO relationship and serial murders were higher. In the second type "convenient disposal (n = 32)", likely to abandon victim body in home and trash, the rate of female offenders who assaulted family members was statistically significantly higher among the four types. In the third type "high geographic distance (n = 23)", traveling long distances for corpse disposal, the percentage of cases by co-offenders was likely to be higher than in the other types. Lastly, the offenders in "low evidence destruction effort (n = 24)" were likely to kill other acquaintances and have the least efforts for corpse dismemberment and disposal. From these results, the criminal profilers can estimate mutilation homicide offenders on the basis of efforts of corpse dismemberment and disposal.

“…This research also found sharp force to be the most common cause of death. Chopin and Beauregard (2020) examined the differences between the crime commission process of sexual murderers who did and did not dismember the victim, by analysing both solved and unsolved cases occurring in France and Canada. They found that dismemberment occurred more often as part of sexual deviance with an organised modus operandi, which involved offenders carrying out the offence in accordance to pre-existing plans.…”

Purpose The purpose of this study was to contribute to the evidence base by analysing the characteristics and motives of homicides involving acts of dismemberment. Design/methodology/approach The current study explored offence, victim and offender characteristics and the motives for 71 homicides involving dismemberment using open source data. All cases included in this study were investigated in the UK between 1970 and 2016. A non-metric multi-dimensional scaling procedure smallest space analysis (SSA) was used to explore the characteristics and motives derived from a content analysis of homicide data sourced online. Findings A distinction between expressive and instrumental characteristics was observable with three thematic regions identified: instrumental – defensive, instrumental – predatory and expressive – affective. Support was found for previously identified motives for criminal dismemberment, with defensive being the most common motive identified in 63% (N = 45) of the cases. Originality/value The implications of the findings are discussed with suggestions made for future research. The findings have practical implications for assisting law enforcement and forensic and clinical practitioners in further understanding offenders who engage in homicidal dismemberment. This includes aiding homicide investigations, in terms of supporting investigators to draw upon offence, victim and offender characteristics and motives for homicides involving acts of dismemberment. Differentiation between cases of dismemberment and understanding of motives also has practical implications for the development of interventions and treatment pathways for homicide offenders who dismember victims.

“…As to the sexual acts, sadistic murderers are more likely to perpetrate vaginal, anal, and postmortem penetration as well as foreign object insertion (Beauregard & Proulx, 2002;Beech et al, 2001;Chopin & Beauregard, 2020c;Higgs et al, 2017;Stefanska et al, 2015). Finally, several studies highlighted that body dismemberment is a specificity of sadistic murderers (Beauregard & Proulx, 2002;Chopin & Beauregard, 2020a). Sadistic offenders follow a similar crime pattern and share common characteristics.…”
