Adolescent homicides in Finland: offence and offender characteristics

Approximately 9% of the homicides in Finland are committed by adolescents under 20 years of age. The purpose of this study was to investigate the offence and offender characteristics in homicidal adolescents. Forensic psychiatric evaluation statements of adolescent offenders accused of a homicide during 1990-2001 were reviewed retrospectively (n=57). In 38% of the cases, there were multiple offenders. In 58% of the cases, the victim was an acquaintance, in 25% a stranger, in 12% a family member and in 5% of the cases an (ex)intimate partner. Sixty-nine percent of the offenders were intoxicated and 21% under the influence of drugs at the time of the killing. The most frequent motives were an argument (25%) and a robbery (25%). Sixty-four percent of the offenders had developmental problems and 42% had a crime history. Approximately half were diagnosed as having a conduct or a personality disorder, but 32% of the offenders were considered not to suffer from a mental illness or substance abuse. For 63%, the level of intellectual functioning was average or above average. There were signs of more than one form of violence in 54% of the cases and 28% of the cases contained excessive violence. The use of multiple and excessive violence was significantly related to the offender age, multiple offenders, offender-victim relationship and substance abuse, but not related to having developmental problems, crime history or mental illness.     

A 24-Year Follow-up Study on Recidivism in Male Mentally Disordered Sexual Offenders With and Without Psychotic Disorders

There is a lack of knowledge on mentally disordered sex offenders (MDSOs) targeting adult victims, especially regarding recidivism patterns and the specific subgroup with psychiatric disorders. This paper presents index offense data, clinical data, and recidivism patterns over up to 24 years in a cohort of 146 MDSOs, with and without psychotic disorders, sentenced in Sweden between 1993 and 1997. At the time of the offense, all offenders were affected by clinical, developmental, and criminal history factors. MDSOs with psychotic disorders only marginally differed from those without, the former being less likely to have been institutionalized during childhood, intoxicated during the index offense, or diagnosed with a personality disorder, substance use disorder, or paraphilic disorder. In the cohort, 3.4% of the MDSOs were reconvicted for a new sex offense over 2 years, 9.6% over 5 years, 13.0% over 10 years, and 17.1% over the entire follow-up period of 24 years. In MDSOs with psychotic disorders, no subjects were reconvicted during the first 2 years, while 2.6% were reconvicted over 5 years, 5.3% over 10 years, and 7.9% over 24 years. Recidivism rates for violent and general reoffenses were 39.0% and 37.7%, respectively, for the cohort of MDSOs, and subjects with psychotic disorders reoffended significantly later in general offenses. In conclusion, MDSOs with psychotic disorders showed the same recidivism pattern as MDSOs without psychotic disorders. Furthermore, recidivism research may preferably focus on follow-up periods of 5–10 years since most offenders appear to recidivate within this timeframe.     

Psychosocial characteristics of criminals committing incest and other sex offenses: a survey in a Taiwanese prison

The purpose of this study was to investigate the psychosocial characteristics of criminals who had committed incest or other sexual offenses. The participants, 240 criminals serving sentences for sex offenses in a Taiwanese prison, were divided into two groups: incest offenders (20.4%) and other sex offenders (79.6%). The psychosocial characteristics taken into consideration included age, parental survival, education, marital status, previous crime records, drug and alcohol abuse, diagnosed mental disorders, and victim abuse at the time of the offense. After an analysis of the data, the authors concluded that even though incest offenders showed fewer mental disorders, they needed psychiatric treatment and that this treatment should be focused not only on their mental disorder and related symptoms but especially to correct their abnormal behavior. Also, attention should be given to their psychosocial characteristics.     

DOES VIOLENCE INVOLVING WOMEN AND INTIMATE PARTNERS HAVE A SPECIAL ETIOLOGY?*

We used data from a survey of inmates who have committed homicide or assault to examine whether men and women who have killed or assaulted their intimate partners are different from other violent offenders. A “gender perspective” implies that intimate partner violence and violence between the sexes have different etiologies than other types of violence, whereas a “violence perspective” implies that they have similar etiologies. Our evidence supports a violence perspective. In general, offenders who attack their partners are similar to other offenders in terms of their prior records, alcohol and drug use, and experiences of abuse. We observed some differences between men who attack women (including their female partners) and other male offenders, but the differences were opposite those predicted by a gender perspective. For example, men who attacked their partners were particularly likely to have been abused by their partners. In addition, men who attacked women were particularly likely to have experienced sexual abuse during childhood and to have been intoxicated at the time of the incident. These results suggest that some well-known predictors of violence are particularly strong predictors of male violence against women and female partners.     

Medico-Legal Evaluation of Adolescent Parricide Offenders: Thirty Nine Cases from Turkey

Parricide which is defined as the murder of one’s parents is a rare event. We describe a consecutive series of adolescent parricide offenders referred to the Council of Forensic Medicine for medico-legal evaluation. Majority of the adolescent parricide offenders were male with a frequency of 79.5%. Age of the offenders ranged from 12 to 18 years old with a median age of 15.13. The majority of the victims were the fathers of the offenders (27; 69.2%). Firearms and cutting devices were the most frequently used weapons. The history of abuse in the family as a motive for the murder was detected in 51.2% of the offenders. The major abuse type was physical abuse. There was no history of psychiatric disorders in the majority of the offenders (37; 94.9%). After the medico-legal evaluation of the adolescent parricide offenders in the Council of Forensic Medicine, psychiatric disorder was diagnosed only in 4 offenders. Schizophrenia was the final diagnosis in 3 cases and paranoid disorder (otherwise unclassified) in only 1 offender. Our study confirmed the frequency of mental illness among adolescent parricide offenders to be very low when compared to adult offenders. Adolescent parricide offenders differ from the other perpetrators particularly in terms of motives of the murder and psychiatric illnesses. Abuse in the family seems to play an important role in these murders. Therefore, it is extremely important that individuals in the legal, criminal justice, social work, psychology, educational and other professional communities be more conscious and informed of child maltreatment and family violence and more research is essential in understanding and preventing adolescent parricide offenders.     

Factor Structure and Reliability of the Revised Conflict Tactics Scales for Incarcerated Female Substance Abusers

Incarcerated women with a history of substance abuse often experience intimate partner violence (IPV), both as victims and as perpetrators. The issues surrounding partner violence and substance abuse are complex, and accurate assessment of this population's experience is critical to ensure proper treatment planning and program development. One of the most common instruments with which to measure IPV is the Conflict Tactics Scales (CTS). Unfortunately, very little published data exist on the revised version of the Conflict Tactics Scales (CTS2), and no data could be located in the literature using this scale with incarcerated women. The purpose of this investigation was to examine the underlying factor structure and reliability of the CTS2 for 359 incarcerated women who had voluntarily participated in a 1–year long substance abuse treatment program. Item analysis revealed a high level of reliability for the overall scale as well as for the individual subscales. Additionally, results from the confirmatory multiple group factor analysis support the 5 underlying subscales, and taken together indicate that the scale is acceptable to use with this population.     

A study of the psychosexual characteristics of sex killers: can we identify them before it is too late?

Thirty-three sex killers were compared to 80 sexual aggressives, 23 sadists, and 611 general sex offenders on sexual history and preferences, substance abuse crime, violence, mental illness, personality, neurological and endocrine abnormalities. Compared to other groups, sex killers started their criminal careers earlier, more often had been to reform school, were members of criminal gangs, set fires, and were cruel to animals. They tended so show more sadism, fetishism, and voyeurism. They more often collected pornography, but they did not use it in their offenses. They more often abused drugs and some suffered from drug induced psychoses. Their most common diagnosis was antisocial personality disorder, but only 15.2% met criteria for psychopathy. Sex killers showed most signs of neuropsychological impairment, grades failure, and learning disabilities. Results suggest that greater emphasis be placed on studying adolescent sex offenders and conduct disordered children which may help identify potential sex killers.     

Sexually violent predators and civil commitment: is selection evidence based?

Sexual offenses represent an alarming proportion of crimes committed yearly. To address these concerns, several states, including South Carolina (SC), have enacted laws requiring sexually violent predators (SVPs) to be civilly committed to treatment. To date, no published study has examined sexual offenders recommended for treatment in SC. This study used a specially designed statewide database (SC-SVP research database) to determine which offender and offense characteristics were associated with increased likelihood of being recommended for civil commitment. Factors correlated with being more likely to be recommended included: being of a younger age at time of evaluation, prior sex convictions, having related and unrelated victims, a higher number of victims, frequent substance use, and a history of suicide attempts. Prior sex convictions, having both related and non-related victims, and a higher total number of victims align with characteristics associated with sexual recidivism. Frequent substance abuse and a history of suicide attempts do not mirror previous findings regarding sexual recidivism. These findings present new information regarding the civil commitment process of offenders being committed to the SC-SVP treatment program, characterize types of offenders committed to SC-SVP treatment program, and provide a foundation for using a computerized database in conducting sex offender research.     

Intimate partner violence against women. Does violence decrease after the entry of the alleged offender into the criminal justice system?

Intimate partner violence(IPV)is simultaneously assumed as a serious crime and a major public health issue,having recurrences as one of its main characteristics and,consequently,re-entries of some alleged offenders in the criminal justice system(CJS).The main goal of this study is to assess if in cases of female victims of IPV,violence decreases after the first entry of the alleged offender in the CJS.A retrospective study was performed based on the analysis of police reports of alleged cases of IPV during a 4-year period.The final sample(n=1488)was divided into two groups according to the number of entries in the CJS(single or multiple)followed by a comparative approach.Results suggest that violence decreases after the first entry of alleged offenders in the CJS.Re-entries were found in only 15.5%of the cases but they were accountable for 3.3 times more crimes on average.Besides,victims of recidivism presented more injuries and required more medical care.Thus,a small group of alleged offenders seems to be more violent and accountable for most of the IPV crimes registered in the CJS suggesting that regardless of legal sanctions aiming to deter violence,these measures may not be enough for a certain group of offenders.This study sustains the need for a predictive model to quantify the risk of repeated IPV cases within the Portuguese population.     

Behavioral and Attitudinal Factors Differentiating Male Intimate Partner Violence Perpetrators With and Without a History of Childhood Family Violence

This study utilized a sample of men (N?=?340) charged with assault against a female partner to assess differences among IPV perpetrators with and without a history of childhood family violence on factors such as angry, controlling and violent behaviors, substance use related behaviors, and attitudes towards women. Over two-thirds of the sample reported childhood exposure to maltreatment or witnessing IPV. Chi-square analyses and t-tests indicated significant differences between perpetrators with and without a history of family violence on eight of eleven measures. Findings suggest perpetrators with a family violence history more strongly endorse ideas that present women and feminine attributes in a negative light. This research demonstrates that while exposure to family violence during childhood is not necessary for IPV to occur, its presence may be a marker for more severe attitudinal and behavioral problems. Findings highlight the need for primary prevention efforts and can inform secondary prevention strategies.     

Consistency in crime site selection: An investigation of crime sites used by serial sex offenders across crime series

PurposeKnowing sites used by serial sex offenders to commit their crimes is highly beneficial for criminal investigations. However, environmental choices of serial sex offenders remain unclear to this date. Considering the challenges these offenders pose to law enforcement, the study aims to identify sites serial sex offenders use to encounter and release their victims and investigate their stability across crime series.MethodsThe study uses latent class analysis (LCA) to identify victim encounter and release sites used by 72 serial sex offenders having committed 361 sex offenses. Additional LCA are performed to investigate the stability of these offense environments across offenders' crimes series.ResultsDistinct profiles of crime sites that are recurrent across crime series are found, suggesting that serial sex offenders present a limited diversity of victim encounter and victim release sites. Encounter sites representative of longer crime series are also identified. Specifically, the use of sites known to "attract" potential victims decreases over series and offenders become more risk-taking in regard of sites used to encounter their victims.ConclusionsThe study identifies patterns of site- selection for the victim encounter and release in cases of serial crimes. Implications for crime linkage and police investigations strategies are discussed.     

Diagnostic profiles of civilly committed sexual offenders in Illinois and other reporting jurisdictions: what we know so far

The records of 377 men civilly committed under Illinois' Sexually Violent Persons Act were compared with similar published samples from seven other states. Civilly committed sexual offenders in Illinois were more likely to be diagnosed with any personality disorder and more likely to exceed the cutoff score for psychopathy than similar offenders in other states. The authors then present a national composite of demographic, victim, and diagnostic information on men referred or pursued for civil commitment in eight states to better understand how these individuals differ from sex offender populations in correctional settings. Results suggest that there may be less victim specificity in sexually violent person (SVP) populations, as although nearly 50% of SVPs are diagnosed with pedophilia, 80% had committed at least one sexual offense against a child or adolescent victim. Across all samples, 72.7% of SVPs were diagnosed with a personality disorder, with antisocial personality disorder the most prevalent.     

Psychopathology in women arrested for domestic violence

This study examined the prevalence of psychopathology among women arrested for violence and whether the experience of intimate partner violence (IPV) was associated with Axis I psychopathology. Women who were arrested for domestic violence perpetration and court referred to violence intervention programs (N= 103) completed measures of IPV victimization, perpetration, and psychopathology. Results revealed high rates of posttraumatic stress disorder (PTSD), depression, generalized anxiety disorder (GAD), panic disorder, substance use disorders, borderline personality disorder, and antisocial personality disorder. Violence victimization was significantly associated with symptoms of psychopathology. Logistic regression analyses showed that sexual and psychological abuse by partners were associated with the presence of PTSD, depression, and GAD diagnoses. Results highlight the potential importance of the role of violence victimization in psychopathology. Results suggest that Axis I and Axis II psychopathology should routinely be assessed as part of violence intervention programs for women and that intervention programs could be improved by offering adjunct or integrated mental health treatment.     

The relationship between substance use, drug selling, and lethal violence in 25 juvenile murderers

The goal of the present study was to determine the relationship between substance use, drug selling, and lethal violence in adolescent male homicide offenders and their victims. The study employed a retrospective review of criminal justice databases and medical examiner records for murders committed by 25 adolescent males incarcerated in the Commonwealth of Virginia juvenile correctional centers from February 1992 to July 1996. The perpetrator sample was 84% African American and 16% white. The average age at the time of the offense was 15.0 years (range = 13.0 to 17.7 years). The victims were 84% male, 60% African American and 32% white. The median victim age was 28.0 years (mean = 34.8, range = 17 months to 75 years). The results indicated that 52% of the murders were committed by juveniles with identified involvement in drug selling, and 28% of the murders were drug-related. Toxicology results indicated recent drug or alcohol use in 27% of the victims; while 74% of the perpetrators reported substance use, 35% indicating daily use. Using discriminant analysis, it was possible to accurately classify 86% of the drug-related murders with the variables of recent victim drug use and perpetrator substance use history. The results indicated that adolescent males involved in the sale and distribution of illegal drugs comprised a significant percentage of those incarcerated for murder. Recent victim drug use and perpetrator substance use may be important variables in identifying drug-related juvenile homicides. These results underscore the link between substance use, drug selling, and lethal violence.     

Commercial Sexual Exploitation of Children: an Assessment of Offender Characteristics

The commercial sexual exploitation of children (CSEC), specifically child trafficking, producers or consumers of child sex trafficking (i.e., prostitution), sexual abuse images, and enticement, has become a growing area of concern. The increasing profitability of CSEC, combined with the clandestine nature of the offenses, calls for immediate attention from international law enforcement and the mental health community. Paramount to the resolution of this global crisis is the identification of the perpetrators of various CSEC crimes. The research pertaining to these offenders is most frequently aggregated and limited to basic demographic data, providing a larger, more generalized picture of CSEC. The purpose of this study is to determine characteristics, within a sample of known CSEC offenders, that differentiate among offenders who engage in sex trafficking as trafficker; engage in sex trafficking as a producer or consumer; produce, distribute, or possess child sexual abuse images; and travel or use enticements to engage in illicit sexual contact with a minor. This observational, survey design includes a record review of 98 offenders who were processed through the FBI Miami Field Office. Results showed that males are more likely to engage in CSEC offenses compared to females. Offenders who collect child sexual abuse images tended to be employed, had no history of prior arrests, and were older than other CSEC offenders. Additionally, engaging in befriending strategies in order to gain access to a victim was also predictive of involvement in child sexual abuse images. Unemployment was the only statistically significant predictor of engaging in child sex trafficking as either a sex buyer or a producer. Finally, perpetrators who engaged in the traveling/enticement of victims were found to be younger, unemployed, single, and without a known history of contact offending. Implications of the findings are discussed.     

Differences in self-report measures by adolescent sex offender risk group

Differences in self-reports among three groups of juvenile sex offenders (N = 162) were examined. Risk was defined as the sum of the following static variables based on interviews with juveniles and others and from written records: type of offense (violent or predatory = 1, not = 0), prior sex offense (any = 1, none = 0), history of sexual abuse (self or family = 1, none = 0), history of substance abuse (self or family = 1, none = 0), history of behavior problems (yes = 1, no = 0), and unstable home life (yes = 1, stable = 0). Low-risk (0 to 2 risk factors), medium-risk (3 factors), and high-risk (4 to 6 factors) groups of offenders were formed. Univariate ANCOVAs indicated that the high-risk group reported less family cohesion, more aggression, lower self-esteem, more social discomfort, and more frequent and extreme sexual fantasies. The implications of these findings for differential identification of and interventions with adolescent sex offenders are discussed.     

Relationship of Substance Use/Abuse with Psychological and Physical Intimate Partner Violence: Variations Across Living Situations

This study addresses whether the relationship between illicit drug use/abuse measures and intimate partner violence (IPV) varies across socioeconomic status, racial status, and environmental indictors of a drug supportive culture. Data from 19,131 respondents who were living with intimate partners and had not been treated for a substance abuse problem in the last year and participated in the National Household Survey on Drug Abuse were analyzed. Marijuana use/abuse was a stronger predictor of IPV and psychological abuse for minorities, but was not a significant predictor of Caucasians’ IPV. Marijuana use/abuse also was a stronger predictor of IPV for those having a low socioeconomic status, but indicators of a drug supportive culture did not moderate the relationship. Minorities’ marijuana use/abuse increased their yelling and insulting behavior toward each other, and this psychological abuse mediated the effect of marijuana use/abuse on IPV. By contrast, stimulant use, sedative use, and alcohol abuse or dependence had independent direct effects on IPV after controlling for psychological abuse. Implications for research and policy are discussed.     

Sociodemographic and diagnostic characteristics of homicidal and nonhomicidal sexual offenders

The aims of this study were to compare the prevalence of psychiatric disorders and "psychopathy" in homicidal and nonhomicidal sexual offenders and to investigate the specificity of previous studies on psychiatric morbidity of a sample of sexual murderers. Information from court reports of 166 homicidal and 56 nonhomicidal sex offenders was evaluated using standardized instruments (SCID-II, PCL-R) and classification systems (DSM-IV). Sexual murderers were diagnosed more often with a personality disorder (80.1% vs. 50%; p < 0.001), especially schizoid personality disorder (16.3% vs. 5.4%; p < 0.05), as well as with sexual sadism (36.7% vs. 8.9%; p < 0.001) and sexual dysfunctions (21.7% vs. 7.1%; p < 0.05). Additionally, they had more often used alcohol during the offense (63.2% vs. 41%; p < 0.05). The results indicate that sexual murderers have more and a greater variety of psychiatric disorders when compared to nonhomicidal sex offenders.
