“…1 1 Space limitations preclude comprehensive coverage of the nuances of research on various multiple homicide offender typologies, and the introduction is intended to broadly describe the various prototypes, the temporal elements therein, and consensus perspectives about the number of homicide victims required for each typology. I recognize the typologies are not mutually exclusive and there is discordant research pertaining to temporal features and victim thresholds (see, Adjorlolo & Chan, 2014; Chai et al., 2024; Heide & Keeney, 1995; Morton, 2008; Reid, 2017; Vincent et al., 2022; Wright et al., 2009). …”

Superhomicide offenders: Nosology, empirical features, and linkages to sexual and multiple murder typologies

The nosology for criminals who murder multiple victims is at once well‐established and controversial, perhaps because theorists have largely segregated such offenders from the broader criminal population. The current study introduces the superhomicide offender, an individual convicted of at least five murders, to locate multiple homicide offenders within the criminological and epidemiological science pertaining to the most pathological offenders, and statistically place them with other conceptualizations of severe offenders at the 95th percentile of the offending distribution. Relative to other capital murderers, superhomicide offenders have lengthier criminal history, greater conviction history, and coextensive psychopathology characterized by psychopathy, sexual sadism, homicidal ideation, cluster A and B personality disorders, and major depressive disorder. Superhomicide offenders are profoundly psychopathic with 20 of the 39 offenders reaching the clinical threshold of 30 or more on the PCL‐R, and 19 of the 39 are sexually sadistic. Regarding extant typologies of sexual and multiple homicide offenders, 15 are serial murderers, 17 are sexual homicide offenders, 17 are mass murderers, and 17 are spree murderers. Twenty‐four of the 39 superhomicide offenders (61.5%) met criteria for multiple typologies, suggesting the new prototype can help unify the study of those who perpetrate multicide and embed them within criminological and epidemiological models that specify pathological antisocial outcomes.

Stranger Danger: Analyzing Offender Behaviors Based on Victim Approach Tactics in Sexual Homicide

Victims of sexual homicide may be deceived by perpetrators who use a friendly approach to gain access to them, making it difficult for the victim to assess the danger posed by the stranger. When investigating sexual homicides committed by strangers, investigators often lack direct information, including how the perpetrator gained access to the victim. To identify potential predictors of the approach method used in sexual homicides, this study analyzed the preferences and behaviors of sexual murderers who target strangers based on their approach method. The results of the logistic regression analysis showed that in comparison to offenders using “blitz” or “surprise” attacks, those using a deceptive “con” approach tended to have more male victims, exploit vulnerability, and exhibit post‐crime organization by relocating the victim's body and successfully disposing of the weapon used in the crime. Their crimes also more frequently involved oral sex and had lower rates of victim beating. This study discusses the investigative implications of these findings.
