Typology Of Offenders Research Articles

The online sexual offender: what we know to date.

Online grooming is an active communicative entrapment network involving a wide range of techniques. The interactions that groomers have with minors online are complex. The purpose of the present literature review was to contribute to the existing knowledge base regarding online sex offender typologies, predatory tactics and techniques. We conducted a review of the current literature by an initial database research of papers published since 1990. Three independent reviewers selected relevant articles, initially based on title and abstract analysis, then by full text in order to make a final determination. After the final selection, a total of 21 articles were reviewed. Overall, abundant data describing both groomer characteristics and grooming strategies are available in the literature, with authors attempting to analyze and adapt these to ever-complex models. However, the various models often feel redundant, determining a certain difficulty in understanding which would be the most suitable model to apply, making comparing data from different studies oftentimes troublesome. In our opinion, it would be desirable to reach a consensus on fewer univocally-interpretable models that would be easier to adopt as preventive tools against online grooming, in combination with other strategies. The present study may provide parents and guardians with information useful for keeping their youth safer while online, as well as data that may assist in the development of policy recommendations and prevention strategies, overall aiming to reduce the phenomenon of online grooming.

Targeting the Most Harmful Offenders for an English Police Agency: Continuity and Change of Membership in the \u201cFelonious Few\u201d

Research QuestionHow concentrated is the total harm of offences with detected offenders (identified suspects) among the complete list of all detected offenders in a given year in an English police agency, and how consistent is the list of highest-harm “felonious few” offenders from one year to the next?DataCharacteristics of 327,566 crimes and 39,545 unique offenders as recorded by Northamptonshire Police in 7 years from 2010 to 2016 provide the basis for this analysis.MethodsCrime and offender records were matched to harm weightings derived from the Cambridge Crime Harm Index (Sherman et al. 2016a; Sherman et al., Policing, 10(3), 171–183, 2016b). Descriptive statistics summarize a concentration of harm identifying the felonious few, changes over time in membership of the “few”, offender typologies and tests for escalation of severity, frequency and intermittency across repeated offences.FindingsCrime harm is much more concentrated among offenders than crime volume: 80% of crime harm that is identified to an offender is linked to a felonious few of just 7% of all detected offenders. While chronic repeat offenders are the majority contributors to harm totals of this group, those with the most general range of offence types contribute the most harm. Individual members of the felonious few rarely maintain that position year on year; over 95% of each year’s list is composed of individuals not present in previous years. Within individual crime histories, we observe a pattern of de-escalation in crime harm per offence over time. “One-time” offenders, those with just one crime record, typically made up a third of the felonious few in both number and harm contribution.ConclusionsThese findings demonstrate the potential to target a small number of repeat offenders for harm reduction strategies using a metric of total crime severity, not just volume, despite a substantial portion of crime harm caused by one-time offenders that may be largely unpredictable.

Adolescent Violence Towards Parents: A Case of Specialisation?

Adolescent violence towards parents (AVTP) is a form of family violence that tests family relationships and the role of parents and can have lasting impacts on all members of families. This study aimed to explore typologies of AVTP offenders based on their criminal justice system involvement, as well as explore differences between groups of AVTP based on their offending. Data were collated by the South Australian Office of Crime, Statistics and Research (OCSAR) in 2017 and included young people who had been apprehended by the South Australian Police between 2008 and 2012 for violence against a parent or step parent. There were a total of 305 young people included in the study, ranging in age from 10 to 17 years. The study found that there were three different groups of AVTP offenders: AVTP offenders, AVTP non-violent offenders who have committed other non-violent crimes and AVTP violent offender who have committed other violent crimes outside of their AVTP offence. Findings suggested that an AVTP offence in isolation is a rarity, and most AVTP offenders commit other non-violent or violent offending. The study concluded that AVTP may be a function of general anti-sociality and occur within the context of a pattern of violent or deviant behaviour, as opposed to a specialist, targeted, isolated incidence of violence.

Investigating homicide offender typologies based on their clinical histories and crime scene behaviour patterns

PurposeThe purpose of this paper is to identify offender typologies based on aspects of the offenders’ psychopathology and their associations with crime scene behaviours using data derived from the National Confidential Enquiry into Suicide and Safety in Mental Health concerning homicides in England and Wales committed by offenders in contact with mental health services in the year preceding the offence (n=759).Design/methodology/approachThe authors used multiple correspondence analysis to investigate the interrelationships between the variables and hierarchical agglomerative clustering to identify offender typologies. Variables describing: the offenders’ mental health histories; the offenders’ mental state at the time of offence; characteristics useful for police investigations; and patterns of crime scene behaviours were included.FindingsResults showed differences in the offenders’ histories in relation to their crime scene behaviours. Further, analyses revealed three homicide typologies: externalising, psychosis and depression.Practical implicationsThese typologies may assist the police during homicide investigations by: furthering their understanding of the crime or likely suspect; offering insights into crime patterns; provide advice as to what an offender’s offence behaviour might signify about his/her mental health background. Findings suggest information concerning offender psychopathology may be useful for offender profiling purposes in cases of homicide offenders with schizophrenia, depression and comorbid diagnosis of personality disorder and alcohol/drug dependence.Originality/valueEmpirical studies with an emphasis on offender profiling have almost exclusively focussed on the inference of offender demographic characteristics. This study provides a first step in the exploration of offender psychopathology and its integration to the multivariate analysis of offence information for the purposes of investigative profiling of homicide by identifying the dominant patterns of mental illness within homicidal behaviour.

Differences in Psychosexual Development Among Child, Peer, and Mixed Juvenile Sex Offenders.

Researchers have examined a number of typologies of juvenile sex offenders, including victim age. Using data from psychological evaluations and the Multiphasic Sex Inventory-II (MSI-II; [Psychological assessment of sex offenders, 2010]), this study compared child offenders (i.e., victims were more than 4years younger), peer offenders (i.e., victims were 4years younger or less), and mixed offenders (i.e., both child and peer victims) on variables including victim, offender, and offense characteristics, and psychosexual development. Peer offenders had more severe sexual offenses, prior status/nonviolent charges, and issues with sexual functioning. Mixed offenders began offending at a younger age and were indiscriminate in gender and relationship of the victim. Mixed offenders were also more likely than child and peer offenders to have prior sex offender treatment, meaning they had previously failed treatment. As juvenile sex offenders are a heterogeneous group, these research findings suggest that child offenders, peer offenders, and mixed offenders' treatment needs differ from each other.

Homicidal Ideation and Forensic Psychopathology: Evidence From the 2016 Nationwide Emergency Department Sample (NEDS).

Homicide is the most serious and costly criminal offense and better forensic and criminological understanding of homicidal ideation as a potential psychobehavioral precursor to homicidal conduct is critical. Using data from the 2016 Nationwide Emergency Department Sample (NEDS) from the Healthcare Cost and Utilization Project (HCUP) distributed by the Agency for Healthcare Research and Quality (AHRQ), we found 64,910 cases of homicidal ideation among a sample of 25.6+million-a prevalence of 0.25%. Numerous conditions conferred increased substantially the likelihood of homicidal ideation including antisocial personality disorder (2406%), schizoaffective disorder (1821%), borderline personality disorder (1557%), paranoid personality disorder (1,504%), schizophrenia (1,143%), obsessive-compulsive personality disorder (921%), brief psychotic disorder (771%), unspecified psychosis (737%), avoidant personality disorder (596%), and schizoid personality disorder (571%), delusional disorder (546%), and other psychotic disorder (504%). Homicidal ideation is comorbid with serious psychiatric and behavioral problems and has important implications for offender typologies and homicidality.

Victimization Experiences and Executive Dysfunction as Discriminating Risk Indicators for Youth Offender Typologies.

Research is becoming increasingly nuanced in its examination of offenders, and thus typological distinctions according to generalist and/or specialization offense profiles may be notable for targeted intervention efforts within and between classifications of offenders. There is a significant body of evidence identifying early-life victimization and executive function deficits as critical developmental antecedents to sexual and non-sexual offending alike, but they have not been exhaustively evaluated as a discernable experience among criminally versatile offenders (youth who commit both sexual and non-sexual crimes). This study aims to address gaps by examining associations between early-life victimization, other traumatic experiences in the home, and executive functioning deficits and then test how disparate offending groups differentially experience these early risks. Using a sample of juvenile-justice-involved youth (N = 200), who committed sexual only offenses (n = 41), non-sexual only offenses (n = 124), and criminally versatile offenders (n = 27), multivariate analysis of variance tests and bivariate correlations were conducted. Results revealed that there were statistically significant correlations between measures of executive functioning and specific incidents of victimization, particularly sexual, physical, and emotional. There were also significant group differences in measures of sexual abuse, physical and emotional abuse, and executive functioning with criminally versatile offenders showing higher rates of physical and emotional abuse and sexual only offenders showing higher rates of sexual abuse and some executive functioning deficits. Practice and research implications are discussed.

Latent class analysis identified phenotypes in individuals with schizophrenia spectrum disorder who engage in aggressive behaviour towards others

Prior research on Hodgins’ (2008) typology of offenders with schizophrenia spectrum disorders (SSD) has revealed inconsistencies in the number of subgroups and the operationalization of the concept. This study addressed these inconsistencies by applying latent class analysis (LCA) based on the most frequently explored variables in prior research. This novel case-centred methodology identified similarities and differences between the subjects contained in the sample instead of the variables explored. The LCA was performed on 71 variables taken from data on a previously unstudied sample of 370 case histories of offenders with SSD in a centre for inpatient forensic therapies in Switzerland. Results were compared with Hodgins’ theoretically postulated patient typologies and confirm three separate homogeneous classes of schizophrenic delinquents. Previous inconsistencies and differences in operationalizations of the typology of offenders with SDD to be found in the literature are discussed.

Using the PAI-A to Classify Juvenile Offenders by Adjudicated Offenses.

To improve understanding and treatment of criminal behavior, researchers have developed typologies of juvenile offenders, primarily focusing on personality traits and criminal history to classify according to type of offense committed. Existing literature has examined underlying personality characteristics found in different subcategories of criminal offenses in juveniles; however, few studies have employed the Personality Assessment Inventory-Adolescent (PAI-A), instead choosing the MMPI-A. A typical classification model of juvenile offenses categorizes offenses into: Interpersonal, Property, and Drug/Alcohol-related charges, to further study within-group differences. The current study examines how personality profiles, examined by the PAI-A, can classify offenders into these offense-type groups. Personality profiles of participants were obtained through pre-sentencing psychological evaluations of 142 juvenile offenders ages 14 to 17. Binary logistic regressions were conducted using PAI-A Clinical, Treatment Consideration, and Interpersonal scales to predict offense-type group classifications. Results yielded statistically significant full models for all offense-type groups, with an average overall accuracy rate of 76.3%. Overall, results suggest that the PAI-A has good predictive power to classify juvenile offender types, and may be more effective in classifying certain types of offenders than the MMPI-A. Notably, Interpersonal and Treatment consideration scales were stronger predictors of offense-type than Clinical scales. This model of juvenile offender classification holds promise for more effective treatment, management, and prediction of behavior for juvenile offenders.

Perfil Sociodemográfico y Delictivo de los Menores Infractores en Medio Abierto en Granada de 2014 a 2017. Análisis Descriptivo y Evolución

The social concern about offenses committed by minors has been reflected in the Organic Law 8/2006, which modifies the Organic Law 5/2000 that regulates criminal responsibility of minors in Spain. However, this group of delinquent minors is heterogeneous and diverse variables have been described in different levels of individual development that would explain emergence and relapse of such behaviors. The aim of the study is to analyse the socio-demographic profile and the criminal typology of juvenile offenders in a probation in Granada province from 2014 to 2017. Methodologically, data were ed from the annual reports of the Integral Service of Open Resources, which d a sample of 2,691 minors. The profile describes a male, 16-18 years old and of Spanish origin. A low academic level and inadequate parenting practices would be relevant risk factors. The main offences are injuries and damages to property.

Transnational Child Sexual Abuse: Outcomes from a Roundtable Discussion.

The phenomenon of men who travel across international borders to engage in child sexual abuse presents significant public health, legal, diplomatic, cultural, and research challenges. Briefed in the current scope of this issue by relevant stakeholders across legislation, research, and social policy, a roundtable discussion held in London aimed to synthesise plenary discussions from multidisciplinary attendees across law enforcement, academia, non-profit, and industry sectors with direct relevance to the UK. Specifically, the roundtable discussions aimed to gather the central themes relating to attendee discussions on the key challenges, affected countries, response strategies, and knowledge gaps. Four key themes were identified from the data, relating to the definition of Transnational Child Sexual Abuse (TCSA), criminal justice, geographical considerations, and issues surrounding tourism/hospitality. The data highlighted four priorities for future development and research, namely developing offender typologies, victim-centric investigative practice, prevalence and definitions, and collaborations. These themes provide insight into the issue of transnational child sexual abuse from the perspective of different disciplines and offer a strategy to prioritise, and collaborate, in the efforts against transnational child sexual abuse.

Typology of substance using offenders of IPV: violence and substance use outcomes

PurposeThe purpose of this paper is to investigate whether aggression and substance use assessed during treatment differ based on risk level for substance-using male offenders of intimate partner violence (IPV).Design/methodology/approachSecondary analyses were conducted using data from Easton et al.’s (2017) study on substance-dependent IPV offenders. A cluster analysis was utilized in order to classify participants into typology groups. Analyses of covariance were conducted in order to determine group differences in aggression and substance use during treatment.FindingsThe paper provides results-related response to treatment based on offender typology. Results appear to reflect two typology groups with significant differences in psychopathy among groups. High-risk offenders demonstrated higher rates of violence throughout treatment compared to moderate- and low-risk offenders; however, no differences in substance use outcomes were found.Research limitations/implicationsA limitation of the study is the extent to which the results can be generalized beyond substance using IPV offenders. Further investigation of treatment outcomes including alternate measures is needed in order to better translate theoretical typologies to clinical settings.Practical implicationsResults provide support for differentiating treatment for substance-using male offenders of IPV based on typology as those with low/moderate risk level appear to be distinctly different and have different treatment outcomes compared to high risk level offenders.Originality/valueAlthough the relationship between risk level and treatment outcomes has been researched with Drug Court Offenders, treatment outcomes based on typology has not been evaluated among substance using male offenders of IPV.

Comparing Solo- and Co-Offending Female Sex Offenders on Variables of Pathology, Offense Characteristics, and Recidivism.

Due to the smaller proportion of female sex offenders (2%-12% of all sexual offenses) compared with male sex offenders, we know much less about these women to aid in the assessment, treatment, and prevention of their offending behavior compared with men. One promising distinction in female sex offender typology is solo-offending females versus females who offend with a male co-offender. The current study uses a sample of 225 incarcerated female sex offenders to compare solo and co-offending women on variables of psychopathology, criminal history, victim and offender information, and recidivism rates. Results indicate that solo offenders are more likely to have male, unrelated victims, score higher on dominance and aggression, and are more likely to generally recidivate. Solo versus co-offending status was not a significant predictor for sexual recidivism. Implications for assessment and treatment are discussed.

Women’s Pathways to Crime: A Heuristic Typology of Offenders

The current study proposes a heuristic model for classification of female offenders into groups based on key variables relevant to women’s backgrounds and programming needs. We utilize a mixed-methods approach with a sample of 60 women incarcerated in a maximum-security prison. We develop qualitative, person-centered groupings of female offenders, and then use quantitative analyses to provide more detailed data on each group. Findings demonstrate five distinct groupings: aggressive career offenders, women who killed or assaulted persons in retaliation or self-defense, women who maltreated children, substance-dependent women experiencing intimate partner violence (IPV), and social capital offenders. These findings lend support to prior research on pathways and typologies of women’s offending, and decision rules effectively “triage” cases according to most pressing needs. The model offers unique utility for researchers, practitioners, and policy makers working with women in the criminal legal system.

Revitalizing Profiles of Runaways: A Latent Class Analysis of Delinquent Runaway Youth

Many runaway youth experience an overabundance of negative life events before, during, and after running away from caregivers. In order to better understand, prevent, and treat adolescent runaways based upon the unique experiences they endure, researchers have created typologies of runaway youth. Building on previous research, this study developed a statistical typology of runaway youth offenders using a sample of 29,204 runaway youth referred to the Florida Department of Juvenile Justice. Based upon key predictors and features of adolescent runaways including abuse, trauma, antisocial peers, delinquency, mental illness, school problems, and more, a series of latent class analysis models indicate that five sub-types of runaways exist within three larger behavioral/feature domains. These results suggest that runaways are a heterogeneous group with highly unique experiences and risk factors that occur before and after the runaway experience. In addition, grouping of runaways based solely upon motivation, individual characteristics, victimization, or offending is too narrow of a perspective.

“Otis”: A Case Study of an Online Attempt to Purchase Children for Sex

ABSTRACTThe researchers analyzed court documents to develop a case study of an individual convicted of buying sexual services from exploited children. Findings indicate that the subject deviates from preexisting victim selection processes and demonstrates characteristics inconsistent with existing sexual offender typologies that likens offender behaviors to the hunting techniques and behaviors of predatory animals. As evidenced in the case study, the individual perceived the victims solely as a means of deviant sexual satiation and did not participate in traditionally established victim acquisition techniques. In addition, the researchers propose adopting terminology that adheres to the term consumer rather than buyer as it better represents some offenders’ disconnect and lack of empathy in the victim acquisition process.

Informing the Understudied R: Exploring and Advancing Typological Research

Creating offender typologies has become a growing interest and a potential method of improving understanding of programming needs and potential placements. Most typological research has only explored and described potential offender types. Relatively few studies have attempted to confirm the existence of created typologies or examine how offenders in each type predict important outcomes. Utilizing a large sample (N = 37,111) of reentering male offenders from Washington State Department of Corrections, we computed both an exploratory and confirmatory latent class analysis. After the confirmation of six offender types, we examined each type’s likelihood of several recidivistic outcomes. We anticipate that the described typology will assist case management, prioritizing offender needs, optimizing treatment services, and determining sequencing of multiple treatment types.

Internet sexual solicitation of children: a proposed typology of offenders based on their chats, e-mails, and social network posts

ABSTRACTAlthough researchers have examined sexual solicitation of minors online, there is limited research on the content and patterns of victim-offender chats. These chats have potential use in investigations for triaging and prioritising cases, enhancing understanding of offenders, developing treatments, and crafting education and policy to prevent sexual solicitation of minors online. As part of a broader effort on Internet crimes against children (ICAC), we examine offender chat logs, email threads, and social network posts from state and local task forces on ICAC for a sample of 200 offenders in communications with undercover officers. We use mixed-methods analyses to identify key elements in these cases and propose a typology of online solicitation offenders: cybersex-only offenders, schedulers, cybersex/schedulers, and buyers. These findings provide support and expansion of existing research on offender types using a larger and more geographically diverse sample. Implications for research, practice, and policy are discussed.

A Thematic Analysis of the Motivation Behind Sexual Homicide From the Perspective of the Killer.

Using thematic analysis, this study explores the motivation to commit sexual homicide from the perspective of the perpetrator. In the process, it revisits motivational models and offender typologies that have been put forward to explain such offenses. From the homicide narratives of eight sexual homicide offenders detained in a high security hospital in the United Kingdom, four themes were found which appeared significant in terms of understanding the offenses committed. These themes were labeled as follows: (a) avenging sexual abuse, (b) events leading to a catathymic reaction, (c) homicidal impulse, and (d) emotional loneliness. Although these findings are not inconsistent with previous research, we argue that the current literature fails to capture the complexity associated with these offenses. We also argue that the context or situation in which sexual homicide occurs is a crucial feature of the offense, and one which has not been adequately taken into account by motivational models.

Characteristics of survivors of juvenile sex trafficking: Implications for treatment and intervention initiatives

Abstract The Behavioral Analysis Unit (BAU) III of the FBI conducted a study that expands upon a typology of offenders engaging in the sex trafficking of juveniles (STJ) ( Hargreaves-Cormany, Patterson and Muirhead, 2016 ) by developing a STJ Survivor Spectrum of Characteristics. All 179 STJ survivors were included in the latent class analyses (LCAs). Further, a binary logistic regression (BLR) analysis was conducted to examine potential for increase in substance use. Data utilized for the study was derived from protocols developed to obtain demographic information on the offenders and survivors and various aspects of the nature of the criminal act(s) perpetrated by the offender. The second author's expertise and practical knowledge from the field regarding STJ offenders and survivors as well as their interviews were utilized to substantiate the empirical findings. The STJ survivors' age, known increases in substance use, motivation to cooperate/testify and family structure were used as indicators within the LCAs. Three latent classes emerged comprised of different STJ survivor age groups. Results suggested that differences between classes are likely attributed to developmental considerations/maturation. The BLR suggested that age of the STJ survivor was predictive of increase in alcohol use. Qualitative analysis of interviews provided in depth data and a lens into the perspectives of STJ survivors. Results enhance understanding of STJ survivors and inform treatment/intervention initiatives which may result in prevention/reduction of harm to juveniles.
