Psychopathy among condemned capital murderers

Psychopathy is an important forensic mental health construct. Despite this importance, the research base of psychopathy among individuals convicted of capital murder is limited. Archival data were collected from a sample of 636 persons convicted of capital murder and sentenced to death in the State of California. Psychopathy was assessed using the Psychopathy Checklist – Revised (PCL-R) instrument. Data on criminal careers and other behavioral disorders were also extracted. The sample mean PCL-R total score was 23.31 (SD = 9.92) and one-third of individuals in this sample were considered clinically psychopathic with PCL-R total scores of 30 or greater. Factor analytic examination yielded support for four facets: affective, interpersonal, lifestyle, and antisocial. Criterion validity findings revealed positive correlations of psychopathy scores with Antisocial Personality Disorder (ρ = 0.72), Conduct Disorder (ρ = 0.46), sexual sadism (ρ = 0.24), Oppositional Defiant Disorder (ρ = 0.20), ADHD (ρ = 0.15), arrest charges (r = 0.56), prison sentences (r = 0.53), and age of arrest onset (r = −0.57). Individuals convicted of capital murder and sentenced to death reflect heterogeneity in psychopathy with some individuals exhibiting pronounced psychopathic features.     

Women murderers and victims of abuse in a southern state

We consider the hypothesis that abused women who kill their abusers are not socially different from other abused women. Comparing two groups of women from a Deep South state, one group incarcerated for killing their partners (n=21) and the other served by a shelter for battered women (n=273), we find mixed support for the conclusion that the two groups represent a homogeneous general population of abused women. The women incarcerated for killing their male partners appear to be more isolated from the social mainstream and in greater perceived danger than the women who used the shelter. An earlier version of this paper was presented at the 1990 Southern Sociological Society Annual Meetings. Invaluable comments on earlier versions of the paper were received from Judith Stitzel, Shirley Dowdy, Ann Paterson, Sally Maggard, Janet Curry, Jon Conte, Mary Jo Ullom, and Lorrie Hardy.     

Profiles in the offending process of nonserial sexual murderers

The aim of this study was to investigate specific pathways in the offending processes of nonserial sexual murderers and to examine possible relationships with different precrime, per-crime, and postcrime factors. Included in this study were 36 offenders who have committed at least one sexual murder against a female victim and they were classified using cluster analysis. Participants using the sadistic pathway planned their offenses and used physical restraints during the offenses. Furthermore, they mutilated and humiliated their victims. Finally, they hid the bodies of the victims. Participants using the anger pathway had not premeditated the homicide. Mutilation, humiliation, and physical restraints were less predominant with these participants than with those using the sadistic pathway. Moreover, these offenders were more likely to leave the bodies at the crime scenes after the killings occurred. These two profiles are compared with empirical studies addressing sexual homicide.     

Posttraumatic stress disorder in murderers

Three case histories of men who suffered posttraumatic stress disorders after committing homicides are presented. These men were relatively young and had chaotic childhoods and minimal criminal histories. Each had killed a woman with whom he had a significant but intensely turbulent emotional relationship. The killings all occurred during altered mental states that were unrelated to the use of drugs or alcohol. The clinical significance and some of the medicolegal implications of this phenomenon are discussed.     

A survey of the psycho-social aspects of murderers in Iran

The psycho-social aspects of 72 murderers (one female, 71 males) were studied. The murderers came from the Khoozestan and the Lorestan provinces of Iran. One of them had been transferred from the north of Iran (probably on exile).The murderers were mostly from lower social classes and crowded homes. The majority of them had worked as unskilled labourers or farmers. A great number of them regretted their action but a few were proud of what they had done. They believed that they had saved the chastity of their family which is very important in Islam.None of them were epileptic nor had any history of it. Four claimed to be nervous. Eight were alcoholics and three were addicted to drugs. One of them was suspected of having manic-depressive psychosis and only one had paranoid schizophrenia. The female and four of the males were psychopaths.     

Mass murderers in the United States: predictors of offender deaths

Objective: many mass murderers appear to care more about harming others than they do about protecting themselves, and they often commit suicide or refuse to surrender and are killed by police. The present study offers the first in-depth investigation of differences between mass murderers who live and die as a direct result of their offenses. Method: data on 308 offenders in the United States from January 2006 to May 2014 are subjected to quantitative analysis, including logistic regression. Results: findings suggest that those who die are older, less likely to have co-offenders, and more likely to commit public mass killings or family killings, which corresponds with Durkheim’s theories of suicide in numerous ways. Conclusion: ultimately, several specific improvements in suicide prevention strategies could potentially help to reduce the prevalence of these high-fatality crimes.     

The paraphilia-related disorders: an investigation of the relevance of the concept in sexual murderers

Paraphilic disorders (PAs) and sexual preoccupation are known risk factors for recidivism in sexual offenders. Nonparaphilic sexual excessive behaviors-so-called paraphilia-related disorders (PRDs), like paraphilias, are also characterized by sexual preoccupation and volitional impairment and can be diagnosed in paraphilic men. The prevalence and clinical significance of PRDs in sexual homicide perpetrators, however, is unknown. We investigated the relationship between PAs and PRDs retrospectively in a sample of 161 sexual murderers. Four groups were compared: men without a PA or a PRD diagnosis, men with at least one PRD but no PA, men with at least one PA but no PRD, and finally, those with a combination of both (PA+PRD). The PA+PRD group had the most lifetime cumulative sexual impulsivity disorders, more developmental problems, the highest persistent frequency of sexual activity, the highest number of previous sexual offences, more sexual sadism, and compulsive masturbation. Men of the PRD subsample had suffered more from childhood sexual abuse, showed more promiscuity, psychopathy, and alcohol problems. The use of the PRD concept in this special offender group should be further investigated with prospectively designed studies.     

Female murderers in a southern city, 1975–1992

A study of a population of 36 females arrested for homicide in a southern, nonurban city from 1975 to 1992 was conducted using both qualitative and quantitative data. The study explored the demographic, social, legal, and offense characteristics of female homicide offenders as well as events leading to the murder. The profile of female homicide offenders in a southern, non-urban setting that emerged from this study is supportive of earlier studies focusing on female homicide offenders in large urban areas.     

Case histories in forensic medicine

Case histories make up a great part of publications in forensic medicine, especially forensic pathology, although considered low on the hierarchy of evidence based medicine because of its inherent anecdotal nature. Meanwhile some journals exclude case histories categorically from publication. The boom of case histories in forensic medicine has not only opportunity reasons (easily [even mental] and cheap to do) but also structural reasons: due to its tasks in case work many items of forensic medicine can not be simulated experimentally for ethical reasons (violent death, traumatic injuries, sexual assault, poisonings, influence of alcohol and drugs on driving ability and legal responsibility, medical malpractice, adverse events during medical care). In these fields the role of case histories is mainly the augmentation of experience based knowledge. However, quality aspects have to be considered and case histories should be the basis for systematic or hypothesis based research.     

A comparison of rapists and sexual murderers on demographic and selected psychometric measures

This study compared 58 sexual murderers and 112 rapists who were about to undergo treatment in prison for their sexual offending behavior. The two groups were compared on background, personality, offense, and victim characteristics. The sexual murderer group were less likely to have been involved in a relationship at the time of their index offense, generally attacked older victims, and had higher self-esteem. The rapist sample were found to have more violent previous convictions and scored higher on measures of historical deviance (nonsexual), paranoid suspicion, and resentment. No differences were found on the personality or clinical syndrome scales of the Millon Clinical Multiaxial Inventory-III. However, the rapist sample had significantly higher mean scores on the Paranoid Suspicion, Resentment, and Self-Esteem subscales of the Antisocial Personality Questionnaire. Future research should compare the two groups on dynamic or changeable factors to determine differential treatment needs.     

The influence of brain abnormalities on psychosocial development, criminal history and paraphilias in sexual murderers

The aim of this study was to investigate the number and type of brain abnormalities and their influence on psychosocial development, criminal history and paraphilias in sexual murderers. We analyzed psychiatric court reports of 166 sexual murderers and compared a group with notable signs of brain abnormalities (N = 50) with those without any signs (N = 116). Sexual murderers with brain abnormalities suffered more from early behavior problems. They were less likely to cohabitate with the victim at the time of the homicide and had more victims at the age of six years or younger. Psychiatric diagnoses revealed a higher total number of paraphilias: Transvestic fetishism and paraphilias not otherwise specified were more frequent in offenders with brain abnormalities. A binary logistic regression identified five predictors that accounted for 46.8% of the variance explaining the presence of brain abnormalities. Our results suggest the importance of a comprehensive neurological and psychological examination of this special offender group.     

Sexual murderers of children: developmental, precrime, crime, and postcrime factors

The amount of empirical research on men who commit sexual murders is scarce, and no distinction has been made between those who have victimized adults and those who have victimized children. Therefore, to better understand specifically sexual murderers of children (n = 11), comparisons were performed with a group of sexual murderers of adult women (n = 66) on developmental, precrime, crime, and postcrime factors. It appears that sexual murderers of children are more often victims of sexual abuse during childhood and present more often deviant sexual fantasies as compared to sexual murderers of women. The results show also that sexual murderers of children more often use pornography prior to crime, have contact with the victim prior to crime, and commit a crime more often characterized by premeditation, strangulation, the hiding of the body, and its dismemberment than the sexual murderers of women.     

Exploring the criminal histories of stranger sexual killers

Although sexual homicide is receiving increasing research attention, few studies have examined the criminal histories of sexual killers in any detail. This study examined the criminal histories of 81 British stranger sexual killers to determine whether they were generalist, specialists or both and whether their criminal histories reflected violent, sexual, marginality and over control pathways. Results found most stranger sexual killers were generalist offenders and sexual homicide was part of a varied criminal repertoire and non-sexual crimes predominate. This ‘antisocial orientation’ means future offending may not be limited to sexual violence. Criminal histories reflected the violent, sexual, marginality and over control pathways, but offenders in the violent pathway were more criminally orientated. The clinical and investigative implications of these findings were considered as they suggest knowledge of the criminal histories of stranger sexual killers is an important consideration for criminal justice professionals.
