Homicide Offenders (homicide + offender)
Selected AbstractsExcessive violence and psychotic symptomatology among homicide offenders with schizophreniaCRIMINAL BEHAVIOUR AND MENTAL HEALTH, Issue 4 2006Taina Laajasalo Background,It is not currently known how psychotic symptoms are associated with the nature of violence among homicide offenders with schizophrenia, or, more specifically, whether different psychotic symptoms are differentially linked with excessive violence. Aim,To identify factors associated with the use of excessive violence among homicide offenders with schizophrenia. Methods,Forensic psychiatric examination statements and Criminal Index File data of 125 consecutive Finnish homicide offenders with a diagnosis of schizophrenia were analysed. Results,Nearly one-third of the cases in this sample involved extreme violence, including features such as sadism, mutilation, sexual components or multiple stabbings. Excessive violence was a feature of acts when the offender was not the sole perpetrator or when there was a previous homicidal history. Positive psychotic symptoms, including delusions, were not associated with the use of excessive violence. Conclusions,These results highlight the importance of variables other than clinical state when examining qualitative aspects of homicidal acts, such as the degree and nature of violence, by offenders with schizophrenia. Further study is needed with a more specific focus on the qualities of the violence among different subgroups of offenders, but inclusive of those with psychosis.

Putkonen Objective: To study if later risk of violent offending and criminality among high-risk children can be estimated quantitatively on the basis of parental crimes. Method:, The criminal and prison records of the offspring (N=11) of homicide recidivists (N=36) were compared with data from controls (N=220) who were matched for sex, domicile of birth and date of birth and death. Results:, The risk (odds ratio) was increased up to 24-fold for violent crimes (P=0.01), and up to 17-fold for criminality (P=0.0008) among the offspring of homicide recidivists. Conclusion:, The quantitative risk of a child for later violent offending and criminality can be estimated on the basis of parental homicide recidivism. This kind of method could be used to choose target groups for early preventive interventions, and to study the effectiveness of prevention.

This study examined race and age influences on victim,offender relationship for juvenile and adult SHOs. A large sample (N = 3868) from the Supplemental Homicide Reports (1976,2005) was used. Analyses of victim,offender patterns included examining victim age effects (child, adolescent, adult, and elderly). The findings revealed several race- and age-based differences. Black offenders were significantly overrepresented in the SHO population. This finding held for juveniles and adults independently. White SHOs were highly likely to kill within their race, "intra-racially" (range 91,100%) across four victim age categories, whereas Black SHOs killed both intra-racially (range 24,82%) and inter-racially (18,76%), with the likelihood of their killing inter-racially increasing as the age of the victim increased. This study underscores the importance of considering victim,offender racial patterns in sexual murder investigations, and it offers practical implications for offender profiling.

We investigated if psychopathy among homicidal offenders is associated with criminal offending among the offenders' offspring. The basic sample consisted of consecutive Finnish homicide offenders (during 1995,2004) who had been subjected to a forensic psychiatric examination and rated for a file-based PCL-R, and their offspring. Criminal behavior among both genders of the offspring was more common than in the general population. In general, the offspring's crimes against others (e.g., threat, intimidation, deprivation of freedom, breach of domicile) were associated with their parent's psychopathy. A grandfather's major mental disorder was associated with a high rate of crime committed by the offspring. Especially, the sons of male psychopathic homicidal offenders had the highest rate of committing crimes, which was often expressed as vandalism. However, both genders of offspring seem to require special preventive programs to ameliorate these problems. [source] The Motivation Behind Serial Sexual Homicide: Is It Sex, Power, and Control, or Anger?,JOURNAL OF FORENSIC SCIENCES, Issue 4 2006Wade C. Myers M.D. ABSTRACT: Controversy exists in the literature and society regarding what motivates serial sexual killers to commit their crimes. Hypotheses range from the seeking of sexual gratification to the achievement of power and control to the expression of anger. The authors provide theoretical, empirical, evolutionary, and physiological support for the argument that serial sexual murderers above all commit their crimes in pursuit of sadistic pleasure. The seeking of power and control over victims is believed to serve the two secondary purposes of heightening sexual arousal and ensuring victim presence for the crime. Anger is not considered a key component of these offenders' motivation due to its inhibitory physiological effect on sexual functioning. On the contrary, criminal investigations into serial sexual killings consistently reveal erotically charged crimes, with sexual motivation expressed either overtly or symbolically. Although anger may be correlated with serial sexual homicide offenders, as it is with criminal offenders in general, it is not causative. The authors further believe serial sexual murderers should be considered sex offenders. A significant proportion of them appear to have paraphilic disorders within the spectrum of sexual sadism. "sexual sadism, homicidal type" is proposed as a diagnostic subtype of sexual sadism applicable to many of these offenders, and a suggested modification of DSM criteria is presented. [source] Investigating the nature of expressiveness in stranger, acquaintance and intrafamilial homicidesJOURNAL OF INVESTIGATIVE PSYCHOLOGY AND OFFENDER PROFILING, Issue 3 2005Stephanie K. Last Abstract This study explores the role of the victim,offender relationship in the dynamics of homicide, by examining the crime scene behaviour of 25 intrafamilial, 30 acquaintance and 27 stranger homicide offenders (n = 82). Six crime scene variables were examined: ,Weapon from the scene', ,Excessive wounding', ,Facial trauma', ,Multiple wounds to a single area', ,Post-mortem activity' and ,Manual violence'. The first objective was to identify whether these variables could be combined to form a partially ordered scale of expressiveness. The second was to examine whether the nature of this expressive crime scene varied according to the victim and offender relationship. It was hypothesised that the intrafamilial homicides would be characterised by a more expressive crime scene. This was examined by Partial Order Scalogram Analysis which supported the hypothesised link between the level of expressed emotion evident in the crime scene and the nature of the victim,offender relationship. Further analysis on the individual variables revealed that the best single predictor of the relationship between victim and offender was the presence of multiple wounding. These findings are discussed both as contributing to a theoretical understanding of the emotional salience of crime scene actions when killing a family member, and in practical terms in relation to the significance of these variables for both police investigations and clinical interventions with homicide perpetrators.

Gabrielle Salfati Abstract To examine if serial homicide offenders are consistent across their crimes, a model was developed empirically that could be used to distinguish between crimes that were instrumental and those that were expressive. The first known three offences in each series of 69 US serial homicides committed by 23 offenders, were examined and the instrumental and expressive themes determined. Three models were then explored that test for consistency across these themes. The most liberal model was found to classify all of the offences effectively and to reveal complete consistency across the three crimes for all offenders. The implications of these results for offender profiling and further study of serial homicide are discussed. Copyright © 2005 John Wiley & Sons, Ltd. [source] Comparing single and serial homicide offenses,BEHAVIORAL SCIENCES & THE LAW, Issue 3 2004Gretchen W. Kraemer J.D., Ph.D. 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.
