Lessons from serial murder in South Africa

The systematic study of serial murder in South Africa is a newly developed field. This research demonstrates the similarities and differences between South African serial murderers and those found elsewhere. The most marked difference is the higher incidence of cross‐ethnic offending, the lower rate of ‘team killers’, and the lack of female serial murderers in South Africa. South African offenders display similar geographical behaviours to foreign serial murderers. Overall, South African offenders display more behaviour in common with their non‐European counterparts than serial murderers from the USA. South African serial murderers display certain diagnostic and developmental features that are different from those reported in North American serial murderers. Of these, the most notable is the seeming lack of sexually violent conscious fantasy. There are also fundamental similarities in experience: exposure to traumatic experiences, and profound interpersonal isolation and distance. This ambivalence is also noted in discussions of the evolution of behaviour in the offences, and in the discussion of motives in serial murder. This demonstrates areas that previous studies of serial murder need to explore further. This study also highlights the need for research into the ways in which offence behaviours are affected by the social environment. Finally, the analysis of serial murderers in South Africa suggests ways in which serial murder can be tackled. Copyright © 2004 John Wiley & Sons, Ltd.     

Temperament and character inventory in homicidal, nonaddicted paranoid schizophrenic patients: a preliminary study

This study assessed the personalities of 13 murderer schizophrenics using Cloninger's Temperament and Character Inventory, controlling different factors such as institution, treatment, detention or loss of liberty, and can discriminate between schizophrenic patients involved in homicide, schizophrenics with no past violent behavior, paranoiac murderers, and imprisoned murderers with no psychiatric history. Results show significantly that murderer schizophrenics had significantly higher scores on the subscale, Self-transcendence, than other groups, which suggests that Self-transcendence as measured may be an aggravating factor for schizophrenia and may be found in the personality of schizophrenic subjects who performed homicidal acts. This dimension constitutes a way and an additional element for diagnosis not available with the DSM-IV criteria. It may help understanding and predicting violent behavior among schizophrenic patients.     

An investigation of some hypotheses concerning rape and murder

The study compared three groups of incarcerated criminals, including 40 men convicted of rape, 40 convicted of murder (of another male) and 40 sentenced for property offenses. A number of personality and attitude scales, behavioral records and a binocular rivalry test were used to test various hypotheses concerning rape and murder. Rapists and murderers did not differ on general control of aggressive behavior but both showed more control than convicted felons. In the binocular rivalry task rapists and murderers were less prone to perceive sexuality than property felons, but the three groups did not differ on perceived aggression toward women. Rapists and murderers were more prone to deny feminine traits than property felons. Rapists had heterosexual experience with more partners than property felons. The three groups did not differ on attitudes toward women or on disinhibition as a mode of sensation seeking. In general, rapists resemble murderers more than ordinary felons and the evidence does not support hypotheses that characterize them as significantly more hostile toward women than are other types of criminals.     

Testing Existing Classifications of Serial Murder Considering Gender: An Exploratory Analysis of Solo Female Serial Murderers

Serial murder is a genre of crime that has received a great deal of media and academic attention, yet, serial murder committed by women has only begun to garner a portion of this attention within the last 15 years. This study examines the reliability of Kelleher and Kelleher's classification rubric, the only classification system developed for female serial murderers, as well as considering Hickey's classification of serial offenders by location. Other variables associated with homicide research have also been examined to determine their roles in both these crimes and classifying offenders. The current research will demonstrate that offender motivation is not an ideal basis for the classification of female serial murderers, who tend to defy simple or singular classification within existing typologies. The other variables analysed indicate that victim–offender relationship and victim approach are important to understanding these female offenders and their crimes, as well as the possible development of more accurate classification systems.

The Inter-Domain Among Personality and Cognition Variables in People Who Commit Murder

The inter-domain among personality (MMPI) and cognition (intelligence) variables in a sample of 137 males charged with first degree or capital murder was examined through canonical analysis. Race was included as a control variable. Two significant canonical correlations were found which contribute to an understanding of the relationship between personality and cognition in violent people. These variates were identified as Problem-solving Focus and Introspective Self-focus. Results also suggest that these inter-domain variates explain the relationship between personality and cognition variables to a greater degree for black murderers than for white murderers.     

Reduced prefrontal and increased subcortical brain functioning assessed using positron emission tomography in predatory and affective murderers

There appear to be no brain imaging studies investigating which brain mechanisms subserve affective, impulsive violence versus planned, predatory violence. It was hypothesized that affectively violent offenders would have lower prefrontal activity, higher subcortical activity, and reduced prefrontal/subcortical ratios relative to controls, while predatory violent offenders would show relatively normal brain functioning. Glucose metabolism was assessed using positron emission tomography in 41 comparisons, 15 predatory murderers, and nine affective murderers in left and right hemisphere prefrontal (medial and lateral) and subcortical (amygdala, midbrain, hippocampus, and thalamus) regions. Affective murderers relative to comparisons had lower left and right prefrontal functioning, higher right hemisphere subcortical functioning, and lower right hemisphere prefrontal/subcortical ratios. In contrast, predatory murderers had prefrontal functioning that was more equivalent to comparisons, while also having excessively high right subcortical activity. Results support the hypothesis that emotional, unplanned impulsive murderers are less able to regulate and control aggressive impulses generated from subcortical structures due to deficient prefrontal regulation. It is hypothesized that excessive subcortical activity predisposes to aggressive behaviour, but that while predatory murderers have sufficiently good prefrontal functioning to regulate these aggressive impulses, the affective murderers lack such prefrontal control over emotion regulation. © 1998 John Wiley & Sons, Ltd.

The nature and dynamics of sexual homicide: An integrative review

The author reviews the definitions, epidemiology, evolving research, offender, and offense characteristics of sexual homicide, a form of intentional killing that occurs in less than 1% of homicides in the United States. Although the extant research is limited by very few comparative studies, repetitive use of small, nonrandom samples, retrospective data, no prospective studies, and the absence of any predictive statistical analyses, the yield over the past 100 years is impressive. The author advances a clinical typology of sexual murderers. The first group of compulsive sexual murderers leaves behind organized crime scenes and are usually diagnosed with sexual sadism and antisocial/narcissistic personality disorders. They are chronically emotionally detached, often primary psychopaths, are autonomically hyporeactive, and the majority experience no early trauma. The second group of catathymic sexual murderers leave behind disorganized crime scenes and are usually diagnosed with a mood disorder and various personality disorders that may include schizoid and avoidant traits. They are hungry for attachment, only moderately psychopathic, are autonomically hyperreactive, and have a history of physical and/or sexual trauma.     

Sex hormones in murderers and assaulters

A study of hormonal levels of violent and nonviolent offenders failed to establish any significant differences among murderers, assaulters, and controls. While the results do not suggest a contributory role for random blood hormone levels in facilitating aggressive behavior, further study of complex interactions is necessary to rule out endocrinological factors.     

Predatory violence aiming at relief in a case of mass murder: Meloy's criteria for applied forensic practice

Mass murder is the result of the complex interaction of several factors. What seems ubiquitous within mass murder are extreme feelings of anger and revenge. Yet despite these intense affective states, mass murders are, as a rule, not behaviorally impulsive, but rather prepared. The presence of extreme hate and anger evokes an impulsive outburst of rage, whereas planning and premeditation point in the direction of a cognitive, rather unemotional deed. This inconsistency is also reflected in reports of offenders' emotional states during the execution of their crimes: while some mass murderers have been described as calm, focused and emotionless during the events, others have shown signs of hostility, confusion, and distress. Considering mass murder from the perspective of its violence mode might shed some light on its nature and dynamics. With respect to the differentiation between affective and predatory violence, Meloy (1988) developed a model for applied forensic practice. The fully documented case of mass murder discussed in this study contains nine indices of predatory violence and one of affective violence. Furious affects of hate and anger were present but appeared to precede the cold-blooded killings. As a matter of fact, it is argued that the offender carried out the predatory murder in order to alleviate the psychological tension and symptoms generated by these severe ego-dystonic affects. The offender thus didn't seem to strive for narcissistic gratification of omnipotence, but rather seemed to aim to solve a problem.     

Firearms and Their Role in Homicide and Suicide*

ABSTRACT: Various arguments against firearms from the standpoint of their role in homicide and suicide are discussed. It is contended by some that murderers are law-abiding citizens who get into trouble because of the availability of firearms. A study in Detroit indicated that both murderers and suicidal persons are prone to misuse the firearm as they would misuse any potential instrument of destruction, independent of gun control measures. If the Second Amendment to the Constitution is to be used by those favoring the right to bear arms, the argument must involve an incorporation of an inherent responsibility toward the use of the firearm; that people wanting to use them should be able to accept reasonable rules and personality qualification as a factor in having the right to obtain them. More effective education and screening of the overly aggressive person or the self-destructive individual are suggested, in terms of school mental health programs, screening at the police precinct level, gun permit application level, and through effective suicide prevention and crisis centers.     

Paranoid thinking in mass shooters

Mass murderers, particularly school shooters, are depicted in the literature as either reacting with rage to taunts and bullying or as being psychopathic. However, examination of diaries and Web sites left by a subset of mass shooters (e.g., Eric Harris, Kimveer Gil, Seung-Hui Cho, Anders Breivik) reveals a different phenomenology than that typically proposed. This group greatly exaggerates the negativity of their treatment as reported by third-party school peers. They become and remain fixated and obsessed with rejection by what they see as an elite in-group whom they see as having unfairly achieved success. Instead of transcending the rejection, they formulate plans to annihilate the transgressors, which they justify as vengeance for the transgressions made against them. The self-exacerbating and obsessive qualities of these perceptions are more consistent with paranoid thinking than with psychopathy. The perceptions feed on themselves and, being part of a closed belief system, expand with time. In the rare cases where the perpetrator survives the mass shooting, they are diagnosed as paranoid schizophrenic. We focus on the pre-psychotic deterioration of their thinking.     

Serial murderers' spatial decisions: factors that influence crime location choice

The outcome of German serial murderer spatial decision making was measured as the straight‐line distance (km) between murderer home locations and each crime location (i.e. body recovery location). Geographic and series development data, as well as information on age, intelligence, motive, marital status, employment status, and mode of transportation of 53 German serial murderers was collected from police and prosecution service files and judicial verdict records. Potential effects of the aforementioned factors on spatial decisions were assessed. Results showed that 63% of the murderers lived within 10 km of their crime locations. Home‐to‐crime distance was negatively correlated with murderer age and positively correlated with murderer IQ score. Results also showed that the mode of transportation used by murderers had an effect on their spatial decisions. Results are discussed in terms of understanding serial murderer spatial decision‐making and implications for police investigations. Copyright © 2005 John Wiley & Sons, Ltd.     

Police/law enforcement and psychology

The number of areas of interface between psychology and law enforcement has grown sharply in the past few decades. At the same time the field of law enforcement-related psychology has acquired increased knowledge and sophistication based on extensive research and practical experience. Areas of interface between law enforcement and psychology include selection of police officer candidates; fitness-for-duty evaluations; prevention and treatment of stress-related disorders; hostage negotiation; psychological profiling of terrorists and mass murderers; and eyewitness testimony. Trends and developments in these areas are surveyed in this article.     

Depictions of Murder in Maine: The Dominant Ideology Thesis

Recent research suggests that popular depictions of crime reflect and reinforce a dominant ideology in which criminals are viewed as rational actors who bear individual responsibility for crime. The research reported here employed a content analysis approach to examine depictions of 108 assailants found in media reports of murders that occurred in Maine from 2008 through 2012. While most of the depictions examined here describe crime as a matter of individual responsibility, this analysis found that many media depictions of Maine’s murderers include content that is sympathetic to the offender and some accounts raise questions about the effectiveness of police services, mental healthcare, and related social services.     

A new Method for Determining Reliability Coefficient: The Consistency Index

It was predicted that murderers would differ in their body-image boundary dimensions from attempted suicides. It was found that the murderers obtained lower barrier scores, which was in opposition to the prediction, and lower penetration scores, which was in agreement with the prediction. Overall, therefore, the prediction was not supported.     

Juvenile homicide in America: how can we stop the killing?

Juvenile homicide remains a serious problem in the U.S., despite recent decreases in the juvenile arresr rate for murder. Reflecting on her clinical experiences evaluating 90 adolescent murderers, the author identifies 15 factors that appear to have contributed to the escalation in juvenile homicide beginning in the mid-198os. These factors can be grouped into five categories: situational factors (child abuse and neglect, and the absence of positive male role models), societal influences (the crisis in leadership and lack of heroes, and witnessing violence), resource availability (access to guns, involvement in alcohol and drugs, and poverty and lack of resources), personality characteristics (low self-esteem, the inability to deal with strong feelings, boredom, poor judgement, and prejuduce and hatred), and their cumulative effects (little or nothing to lose and the biological connection). Strategies to reduce juvenile violence are addressing using parents, schools, communities, government leaders, the media and individuals. ©1997 John Wiley & Sons, Ltd.
