Homicide offender recidivism: A review of the literature

While there exists an abundance of research on the criminal histories of homicide offenders, little is known about their future criminal behavior. This review outlines the current state of knowledge regarding recidivism among homicide offenders. It addresses the dominant theories found within the literature in this field and the prevalence of recidivism among both general and subgroups of homicide offenders. In this literary review, several shortcomings are revealed which point to potential directions for future research.     

Adolescent sex offenders with mental retardation: Literature review and assessment considerations

Working with adolescent sex offenders can be a difficult challenge. When an offender also suffers from mental retardation, this challenge increases. Unfortunately, this has been a largely ignored population, and clinicians working with this group often find little empirical work to assist them. Yet, many theorists posit that addressing sexual offending behavior when the offender is an adolescent may help prevent that behavior from continuing into adulthood. This is important because adult sexual offenders are often very difficult to treat. The current paper begins by reviewing literature on social deficits of individuals who have mental retardation. These deficits may contribute to aberrant sexual behavior among adolescents. The focus of the paper is then a review of literature on adolescent sex offenders, including those with mental retardation. We conclude this review with suggestions for assessment of adolescent sex offenders and with recommendations for future directions.     

Fatherhood and Delinquency: An Examination of Risk Factors and Offending Patterns Associated with Fatherhood Status among Serious Juvenile Offenders

Despite a large body of literature across multiple disciplines on adolescent motherhood, adolescent fathers have been largely absent from empirical research. Previous findings suggest that young men who experience multiple risk factors across a range of life domains have a high likelihood of becoming fathers at an early age, which can negatively impact their developmental trajectories and age-normative transitions (e.g. from school to work). However, little is known about the risk factors for fatherhood among high-risk juvenile offenders; nor is it well understood how fatherhood is related to criminal behavior in this population. The current study investigated risk factors and offending patterns associated with adolescent fatherhood status in a sample of serious juvenile offenders (N?=?1170). Consistent with previous studies, fatherhood status was associated with greater risk exposure among serious juvenile offenders. Furthermore, change in fatherhood status was associated with higher levels of overall offending, aggressive offending, income-related offending, and non-drug-related income offending. In light of these findings, we propose that supports and resources are needed to facilitate juvenile offenders in their role as fathers during this time.     

Comparing serial homicides to single homicides: A study of prevalence,offender, and offence characteristics in Sweden

Multiple and serial homicides constitute around 1.6% of all homicides but have unusually tragic outcomes. The aims of this study were to report the prevalence serial‐homicide offences and the characteristics of serial‐homicide offenders in a non‐North American context. The study included all convicted serial‐homicide offenders in Sweden from 1973 to 2012 (n = 25), as well as a population‐based control sample of single‐homicide offenders collected during 2007 and 2009 (n = 201). Similar to U.S. findings, approximately 1.6% of homicides could be attributed to serial‐homicide offenders. Serial offenders were more often diagnosed with personality disorders and autism‐spectrum disorders compared with single offenders; and serial offences more often involved victims who were female and unacquainted with the offender, as well as planning, sexual motives, and asphyxia as method of violence. One third of serial offences involved actions aimed at disguising the manner of death; such actions were considerably less common in single‐homicide offences. Few offenders displayed the traditional profile of a serial‐homicide offender; however, one third displayed sexual motives, a rate roughly 10 times higher than that in the single‐homicide group. The study concludes that serial‐homicide offenders should be subjected to forensic‐psychiatric examinations and that research involving cross‐contextual differences and similarities in serial‐homicide offenders is needed.     

population growth,economic inequality,and homicide

Empirical research and theorizing on cross-national variations in homicide have been limited by an exclusive focus on the direct effects of national structural characteristics on the rates of homicide. This study is designed to extend this growing body of literature by advancing a conceptual model accounting for an important underlying feature of societies that indirectly elevates national homicide rates. Specifically, it is proposed that a high rate of population growth may have a direct role in bifurcating the distribution of national wealth. Population growth should therefore indirectly increase homicide rates through this mediating factor. This hypothesis is tested with data from 50 nations circa 1990. The data support the expected relationship, indicating (net of several controls) that rapid population growth is an underlying barrier to low homicide rates across nations. The main theoretical implication is that the often observed inverse relationship between level of development and rates of homicide appears to be indirectly driven by differential population dynamics.     

Recidivism among four types of homicide offenders: An exploratory analysis of 336 homicide offenders in New Jersey

Despite a great deal of information on various types of offenders, there is only limited longitudinal research on the offending patterns, typologies, and recidivism of different types of homicide perpetrators. A random sample of 336 homicide offenders who were released between the years 1990 and 2000 from the New Jersey Department of Corrections were identified and followed for a minimum of 5 years. These offenders were tracked to determine if incarcerated homicide offenders who had no criminal histories prior to their homicide conviction recidivated less, and which specific variables correlated with recidivism. As a result of our analysis, we conceptualized a new four-fold typology of homicide offenders: 1) homicide that was precipitated by a general altercation or argument, 2) homicide during the commission of a felony, 3) domestic violence-related homicide, and 4) a homicide after an accident. In conclusion, none of the 336 homicide offenders committed another murder. However, we found the highest recidivism for new violent or drug crimes occurred in the felony homicide group (slightly over one-third), followed by the altercation precipitated homicide offenders (27%), which was in sharp contrast to the domestic violence homicide offenders with less than 10% recidivism due to a new violent or drug offense.     

Girls Arrested for Murder: An Empirical Analysis of 32 years of U.S. Data by Offender Age Groups

Most studies on juvenile homicide offenders (JHOs) have used small samples and have concentrated on adolescent male offenders. As a result, little is known about the population of female juveniles arrested for murder. This study utilized the Supplementary Homicide Report (SHR) database to investigate age differences between younger (aged 6–12 years) and older (aged 13–17 years) females arrested for murder in the United States from 1976 to 2007. As predicted, six variables used to test seven hypotheses with respect to younger and older female JHOs in single victim incidents were significant (victim age, victim gender, victim offender relationship, murder weapon, offender count, and homicide circumstance). Regression analysis revealed that younger girls were seven times more likely than older girls to kill children aged 0–12 years. Girls aged 6–12 years were five times more likely than their teen counterparts to be involved in conflict‐related homicides as opposed to crime‐related homicides. Although approximately the same percentages of younger and older girls killed infants under the age of 1, the victims were significantly different for the two offender age groups. This article concludes with a discussion of our findings and directions for future research. Copyright © 2014 John Wiley & Sons, Ltd.     

Identification of adolescent sexual offenders: A rebt model

The adolescent sexual offender is perhaps one of the most misunderstood, misdiagnosed and maltreated clinical populations facing today's mental health practitioner. They are often the adolescents whom no one wishes to have in their family, school, neighborhood and, sometimes, office. Since this clinical population is relatively new and research has yet to establish consistent findings, attempts to categorize these adolescents are often subjective and inaccurate. This article outlines the problems in traditional diagnostic schemes for identifying adolescent sexual offenders, the myths surrounding the predisposing factors for becoming an adolescent sexual offender, the rationale and process based on Rational Emotive Behavior Therapy (Ellis, 1962) for identifying adolescent sexual offenders and how to discriminate this group from adolescents who engage in inappropriate sexual behavior. These two classifications are the two categories for identifying the adolescent sexual offenders for our program at Children's Service Center in Wilkes-Barre, Pennsylvania. The Children's Service Center adolescent sexual offender program currently has a zero recidivism rate for the past four years.     

Juvenile homicide: The need for an interdisciplinary approach

Most of the empirical literature on juvenile homicide has emerged from the clinical experience of mental health professionals who have diagnosed and/or treated youngsters who killed. After a critical review of this literature, data on 787 juvenile homicide offenders are presented and discussed. These data indicate that intrafamilial killings represent but a small fraction of all homicides perpetrated by juveniles and that there are clear differences between intrafamilial and extrafamilial juvenile homicides.     

South African Serial Homicide: Offender and Victim Demographics and Crime Scene Actions

There is an abundance of literature on serial homicide from a Western perspective that outlines operational definitions, types of offenders and how they prey upon their victims. However, currently, there is a lack of studies that compare serial homicide in different countries. The current study aims to give an overview of the demographics of serial homicide offenders and victims in South Africa and compare these to the demographics of offenders and victims from other currently available empirical studies of other countries. The sample consisted of 33 out of the total 54 solved series in South Africa between 1936–2007, which includes a total of 33 offenders, 302 victims, and 254 crime scenes. Results of the sample as a whole showed that South African serial homicide offenders are similar to offenders in other countries in terms of their actions at the crime scene and victim choice, with some notable exceptions. Additional analysis looked at the offender's consistency of targeting certain types of victims across their homicide series in comparison with the patterns of serial homicide offenders in other countries.

An examination of behavioral consistency using individual behaviors or groups of behaviors in serial homicide

Establishing behavioral consistency in serial homicide offending behavior is essential when linking homicides together and to a common offender. An examination of 35 serial homicide behaviors utilized by 90 offenders in 450 serial homicide cases was carried out to identify whether these offenders consistently performed the same behaviors across their series of homicides and whether it is more effective to examine individual behaviors or groupings of behaviors in order to identify behavioral consistency. This study provides the first empirically based evidence testing the use of using single behaviors as linking factors in linking homicide cases in a series, and shows that this method has inherent difficulties in accomplishing this, thus providing the first wave of empirical testing that questions current theories in the literature on serial homicide, which has suggested that signatures or specific key behaviors are important in understanding the consistency in an offender's behavior across the crimes. Recommendations for future studies on linking using signatures are suggested, including a more in-depth qualitative empirical evaluation of individual series.     

Juvenile homosexual homicide

Limited information exists on juvenile homosexual homicide (JHH), that is, youths who perpetrate sexual homicides against same-sex victims. Only a handful of cases from the United States and internationally have been described in the literature. This study, the first of its kind, examines the epidemiology, victimology, victim-offender relationship, and weapon-use patterns in JHH offenders using a large U.S. database on homicide spanning three decades. The data for this study were derived from the Federal Bureau of Investigation's Supplementary Homicide Reports (SHRs) for the years 1976 through 2005. A total of 93 cases of JHH were identified. On average, three of these crimes occurred annually in the U.S., and there was a marked decline in its incidence over the study period. Ninety-five percent were male offender-male victim cases and 5% were female offender-female victim cases. JHH offenders were over-represented amongst all juvenile sexual murderers, similar to their adult counterparts. The majority of these boys were aged 16 or 17 and killed adult victims. They were significantly more likely to kill adult victims than other age groups, to be friends or acquaintances of the victims, and to use contact/edged weapons or firearms. Most offenders killed same-race victims, although Black offenders were significantly more likely than White offenders to kill interracially. A case report is provided to illustrate JHH. Further research is needed to promote our understanding of the pathogenesis, etiology, and associated risk factors for this aberrant form of murder by children.     

Characteristics of adolescent sex offenders: A review of the research

While significant research has been completed on adult sex offenders, this has yet to be the case for adolescent offenders. This article reviews current research on adolescent sex offenders, discusses the importance of research in this area, and describes directions for future study.     

Post‐incarceration Recidivism of Lone versus Group Juvenile Homicide Offenders

Killings by juvenile homicide offenders (JHOs) who use accomplices have been increasing since the 1980s and currently represent approximately half of juvenile arrests for murder in the United States. Nevertheless, prior research has not compared JHOs who kill alone with JHOs who kill in groups. The present research followed up 30 years later on a sample of 59 male murderers and attempted murderers sentenced to adult prison. This study was designed to analyze whether lone and group JHOs differed on pre‐incarceration, incarceration, and post‐incarceration variables. Significant findings indicated that compared with lone offenders, group JHOs had a higher mean of pre‐homicide arrests and were more likely to be Black, have a pre‐homicide delinquent record, commit a crime‐related homicide offense, and target a stranger. With respect to post‐homicide variables, group JHOs were more likely to be released from prison and more likely to be rearrested. The two types of JHOs did not differ significantly in relation to the number of post‐release violent offenses. Preliminary implications of the findings and avenues for future investigation are discussed. Copyright © 2016 John Wiley & Sons, Ltd.     

Comparing single and serial homicide offenses

Serial homicide has attracted much attention, but little empirical scientific investigation. This exploratory study reports demographic information on a large sample of serial homicide offenders (157 offenders, 608 victims), and compares a subsample of serial homicide offenses with a control group of single homicide offenses. Results show that serial homicide offenders target more women than men, and kill more strangers than family or friends. Single homicide offenders kill men and women in equal frequency, but kill family and friends more often than strangers. Serial homicide offenders kill for apparent sexual motivation more often than for any other reason, while single homicide offenders kill most often out of anger.     

Rorschach comparisons of male juvenile sex offenders and nonsex offenders

Published research is limited on the psychological characteristics of juvenile sex offenders as a subgroup separate from other juvenile delinquents. This study compares 45 male adolescent sex offenders on the Rorschach with a matched group of nonsex adolescent offenders. The two groups differed in total number of responses. Eliminating those protocols of questionable validity due to low productivity in combination with a high lamba, a statistically significant difference in the number of anatomy responses given by the two groups was found. With this exception, the personality characteristics of adolescent sex offenders were similar to those of adolescents who commit only nonsexual crimes. It should be noted, however, that the scoring categories analysed were not exhaustive and that the groups may differ on more recently proposed Rorschach subscales.     

Rorschach Comparisons of Male Juvenile Sex Offenders and Nonsex Offenders

Published research is limited on the psychological characteristics of juvenile sex offenders as a subgroup separate from other juvenile delinquents. This study compares 45 male adolescent sex offenders on the Rorschach with a matched group of nonsex adolescent offenders. The two groups differed in total number of responses. Eliminating those protocols of questionable validity due to low productivity in combination with a high lamba, a statistically significant difference in the number of anatomy responses given by the two groups was found. With this exception, the personality characteristics of adolescent sex offenders were similar to those at adolescents who commit only nonsexual crimes. It should be noted, however, that the scoring categories analyzed were not exhaustive and that the groups may differ on more recently proposed Rorschach subscales (e.g., Isolation Index, Depression Index, and Morbid Content).     

Juvenile homicide: A growing national problem

Arrests for juvenile homicide more than doubled from 1984 to 1991. The present study examined offense characteristics for a national sample of 2,400 juvenile homicide offenders listed in the FBI Supplemental Homicide Reports for 1984 or 1991. Analyses indicate that the largest increases in juvenile homicide can be found among minority males using handguns to kill acquaintances. Juvenile homicides committed in the course of another crime (such as robbery or drug deal) have increased over 200%, while homicides precipitated by an interpersonal conflict with the victim have increased 83%. In comparison to adults, juvenile homicide offenders are much more likely to use a handgun and to act with an accomplice. These results highlight the association between handguns and juvenile homicide.     

An exploration of the current knowledge on young people who kill: A systematic review

This exploratory systematic review assessed the quality of primary studies on young people who kill and synthesised the findings regarding the characteristics of these offenders. An electronic search yielded 12,717 hits of papers published between 1989 and 2012. Of these, 8395 duplicates, 3787 irrelevant hits, and 527 publications not meeting the inclusion criteria of the review were excluded (15 publications were added after searching the grey literature), leaving 23 good quality studies. From these, a further seven were removed due to their small sample size (i.e., n < 30), leaving a total of 16 studies reviewed in detail. A search update was carried out on 2 February 2014 and no further studies meeting the inclusion criteria were found. The results indicate that juvenile homicide offenders are a heterogeneous group and the risk factors for juvenile homicide are cumulative and evolve through life. The findings are mixed, but ten risk factors are identified which appear to be consistent for offenders across the studies reviewed. The limitations of the current review are highlighted and recommendations for future research are outlined, with particular consideration given to improving the quality of the literature in this field.     

Pathways in the offending process of sex offenders who target marginalised victims

Prior literature shows that although marginalised populations are at a high risk of severe violence and homicide, research has focused on their offenders as if they constituted a homogeneous group. On the basis of a sample of 213 sex offenders who targeted marginalised individuals (i.e., sex trade worker, homeless individual, and severe drug user), we investigate the different pathways that these offenders take both prior to and during the commission of their crimes. Results of 2‐step cluster analysis regarding the offender's development, criminal history, crime context, and modus operandi revealed 3 distinct pathways of the offending process. The coercive pathway was characterised by the amount of violence used against the victim. The explosive pathway was defined by offenders who were in a state of rage at the time of the offence. Finally, offenders in the situational pathway committed their crimes out of opportunity and used very little violence. Differences between pathways were investigated with regard to characteristics of the index offence.
