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.

That psychopathy imposes substantial societal costs and economic burden is axiomatic, but monetization studies have overlooked cost estimates of the disorder. The paper aims to discuss these issues.

Drawing on a near census of institutionalized delinquents from Missouri, the current study devised new crime cost measures for self-reported offending.

Youth imposed $30 million in total costs annually in large part due to extensive involvement in robbery, theft, and assault. The most criminally active youth imposed costs in excess of $700 million. Psychopathy features were differentially correlated with crime costs. APSD-SR callous-unemotional traits, mPPI-SF Blame Externalization, mPPI-SF Machiavellian Egocentricity, and mPPI-SF Social Potency were significantly associated with between four and five crime costs. Psychopathic traits associated with ruthless self-interest, callousness, and expectations to control and dominate others manifest in diverse ways including serious violence and repeated property crime. Other features such as mPPI-SF Impulsive Nonconformity, mPPI-SF Stress Immunity, mPPI-SF Coldheartedness, mPPI-SF Carefree Nonplanfulness, mPPI-SF Fearlessness, APSD-SR Impulsivity, and APSD-SR Narcissism had limited associations with crime costs.

To the authors’ knowledge, this is the first monetization study to quantify the effects of assorted psychopathy features on crime costs.

Sexual sadism is a well-known risk factor for severe forms of sexual violence including sexual homicide and serial sexual homicide. The research is decidedly mixed about the association between sexual sadism and other, nonsexual forms of criminal conduct. The paper aims to discuss these issues.

Drawing on data from a census of 225 federal sex offenders from a jurisdiction in the Midwestern USA, the current study examined whether sexual sadism had a spillover effect into nonsexual crimes using correlation, ANOVA, and negative binomial regression models.

Sexual sadism was strongly associated with diverse forms of nonsexual criminal behavior, and sexual sadists had more extensive and versatile criminal careers than sex offenders without a formal diagnosis.

Practitioners should be aware of sexual sadism as a criminogenic risk factor. Sexual sadism is associated with sexual deviance and sexual violence. Sexual sadism also has spillover effects where it is associated with nonsexual offending.

Sexual sadism can be a useful risk factor for other forms of crime and recidivism and has broad application in applied correctional and research settings.

Recent developments in the psychometric assessment of youth psychopathic traits suggest that the inclusion of a conduct disorder (CD) factor to the traditional three factors of the psychopathy construct may improve the incremental validity of these measures. The purpose of the current study is to examine whether the addition of a CD factor incrementally improves the ability of the Youth Psychopathic Traits Inventory Short version (YPI-S) to predict criminal recidivism.

A longitudinal quantitative research design was used with a sample detained male youth (N = 214, M_age = 16.4 years, SD_age = 1.3 years).

Results using the area under the curve analysis suggest that the inclusion of a CD factor slightly improves the capacity of the YPI-S to predict one-year general criminal recidivism, but it does not significantly increase its capacity to predict violent criminal recidivism. Results also indicate that a CD scale outperforms the YPI-S, even with an additional CD factor included, in terms of predicting one-year general and violent recidivism.

Self-reported youth psychopathic trait measures, even those that include a CD factor as a fourth factor, should be used with caution when the aim is to predict youth criminal recidivism.

To the best of the authors’ knowledge, this is the first study using a self-reported youth psychopathic traits measure with a CD factor to examine youth criminal recidivism.

Most burglaries are property offenses yet some offenders perpetrate burglary for the purpose of violent instrumental crimes. Sexual burglars are distinct from non-sexual burglars because the former seek to rape or sexually abuse victims within the homes they burgle whereas the latter seek theft and material gain. It is unclear to what degree burglars who are armed with firearms or knives represent a type of sexual burglar, or perhaps a more severe type of offender who enters homes not merely to rape a victim, but to perhaps murder them as well. The paper aims to discuss these issues.

Drawing on data from 790 felons in Florida, t-test and negative binomial regression models were used to compare armed burglars to offenders who were not convicted of armed burglary.

Compared to offenders not convicted of armed burglary, armed burglars were involved in significantly more instrumental crimes of violence including first-degree murder, kidnapping, armed rape, armed robbery and assault with intent to murder. Armed burglary may be a marker of extreme instrumental violent offending and warrants further study.

To the authors’ knowledge, this is among the first studies of armed burglary offenders and adds understanding to the heterogeneity of burglary offenders and their criminal careers.

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.

The purpose of this paper is to examine the role of a variety of developmental factors on sexual homicide offenders (SHOs), while taking into account other components of sexual homicide theoretical models.

A series of logistic regression models are performed using a total of 616 incarcerated adult male sexual offenders from Canada to distinguish between three groups of sexual offenders, SHOs, violent non-homicidal sex offenders (NHSOs) and NHSOs.

Results indicate that contrary to theoretical models, experiences of victimization are not central to the development of SHOs. Instead, it is the adoption of various problematic behaviors in childhood that appear as most important in the etiology of this particular type of sexual crime. This suggests that the various existing theoretical models of sexual homicide need to be revised and/or tested with additional empirical data.

This is the first study to look at developmental factors using two control groups of NHSOs and violent NHSOs.

Sex offender registration and notification act (SORNA) offenders are a source of scholarly study across the social, behavioral, forensic and legal sciences with the bulk of literature focusing on the legal standing and deterrent value of sexual offender registries. Less research focuses on the offending careers of current SORNA offenders relative to other types of sexual offenders whose current offense is not SORNA. The purpose of the current study is to examine this issue empirically.

Using cross-sectional data from a census of male federal offenders who ever perpetrated a sexual offense from the central USA between 2016 and 2020, the current study used t-tests, logistic regression and negative binomial regression to compare current SORNA offenders to other federal correctional clients in terms of their lifetime offending history, sexual violence and compliance on federal supervision.

Current SORNA offenders are significantly more severe and versatile in their sexual offending, have more extensive criminal careers and criminal justice system involvement, and exhibit significantly increased odds of revocation on supervised release despite controls for age, race and ethnicity. However, sensitivity models that specified the federal Post-Conviction Risk Assessment reduced the effects of SORNA status to non-significance in all models.

SORNA offenders are potentially a significant offender group with evidence of both and given their versatile and specialized lifetime offending and noncompliance on federal supervision. However, current SORNA status is rendered spurious once a risk assessment is controlled suggesting more research is needed to evaluate whether sex offender registries posit greater crime control benefit.

The purpose of this paper is to examine the dark figure of crime among federal sex offenders from the USA to quantify crime victims and sex crime events among those with no official criminal record.

Using data on 119 offenders selected from a five-year census of sex offenders selected from a federal probation jurisdiction in the Midwestern United States, descriptive, partial correlations, and ROC-AUC models were conducted.

In total, 69 percent of offenders self-reported a contact sexual offense during polygraph examination. In total, 34 offenders had zero official record of sexual abuse but non-zero self-reported history of sexual abuse. These 34 clients offended against 148 victims that potentially denoted a minimum number of 148 sex crime events, a median number of 1,480 sex crime events, a mean number of 32,101 sex crime events, and a maximum number of 827,552 sex crime events. Total paraphilias were not predictive of self-reported sexual offending but were strongly associated with prolific self-reported sexual offending.

The dark figure of sexual offending is enormous and the revelation of this information is facilitated by polygraph examination of federal sex offenders. Ostensibly non-contact sex offenders such as those convicted of possession of child pornography are very likely to have a history of contact sexual offending. Consistent with the containment model, polygraph examinations of the sexual history of offenders convicted of sexual offenses should be required to facilitate public safety.
