The purpose of this paper is to examine temperament differences, notably effortful control and negative emotionality, and correlates that distinguish between homicide, violent sexual and other violent juvenile offenders. Exploring heterogeneity among violent offenders is relevant to intervention strategies and policy implications.

Demographic measures, temperament constructs and individual risk factor indicators were assessed across 30,303 violent juvenile offenders (including 397 homicide offenders) in Florida to assess their ability to distinguish among violent juvenile offender subgroups.

Analyses demonstrated temperament constructs distinguish among classifications of violent juvenile offenders with effortful control differentiating homicide and violent sexual offenders from other violent offenders, and negative emotionality distinguishing violent sexual from other violent offenders, with youth having greater negative emotionality and less effortful control being non-sexual violent offenders. Homicide offenders were more likely to be older, male and had histories of gang membership and weapon/firearm offending than other violent offenders, and evidenced greater negative emotionality than violent sexual offenders.

The differences across violent youthful offender subtypes suggest heterogeneity among violent offenders with distinct correlates more predictive of some subtypes than others. Additionally, the temperament constructs of effortful control and negative emotionality are useful in distinguishing violent offender subtypes, which points toward differing intervention/treatment strategies.

Adverse childhood experiences (ACEs) are a broad conceptual framework in the social sciences that have only recently been studied within criminology. The purpose of this paper is to utilize this framework by applying it to one of the most potentially dangerous forensic populations.

Archival data from 225 federal sex offenders was used to perform descriptive, correlational, and negative binomial regression models.

There was substantial evidence of ACEs including father abandonment/neglect (36 percent), physical abuse (nearly 28 percent), verbal/emotional abuse (more than 24 percent), and sexual abuse (approximately 27 percent). The mean age of sexual victimization was 7.6 years with the youngest age of victimization occurring at the age of 3. Offenders averaged nearly five paraphilias, the most common were pedophilia (57 percent), pornography addiction (43 percent), paraphilia not otherwise specified (35 percent), exhibitionism (26 percent), and voyeurism (21 percent). The offenders averaged 4.7 paraphilias and the range was substantial (0 to 19). Negative binomial regression models indicated that sexual sadism was positively and pornography addiction was negatively associated with serious criminal violence. Offenders with early age of arrest onset and more total arrest charges were more likely to perpetrate kidnaping, rape, and murder.

ACEs are common in the life history of federal sex offenders, but have differential associations with the most serious forms of crime.

Homicide is the most severe form of crime and one that imposes the greatest societal costs. The purpose of this paper is to introduce the homicide circumplex, a set of traits, behaviors, psychological and psychiatric features that are associated with greater homicidal ideation, homicidal social cognitive biases, homicide offending and victimization, and psychopathology that is facilitative of homicide.

Using the data from a near population of federal supervised release offenders from the Midwestern USA, ANOVA, multinomial logistic, Poisson and negative binomial regression models were developed.

Greater homicidal ideation is associated with homicide offending, attempted homicide offending and attempted homicide victimization and predicted by gang activity, alias usage, antisocial personality disorder and intermittent explosive disorder. These behavioral disorders, more extensive criminal careers, African American status and gang activity also exhibited significant associations with dimensions of the homicide circumplex.

Developing behavioral profiles of offenders that exhibit homicidal ideation and behaviors are critical for identifying clients at greatest risk for lethal violence. The homicide circumplex is an innovation toward the goal that requires additional empirical validation.
