Classifying serial killers

We attempted to match the appearance and demeanor of 27 serial killers to the postmortem 'signatures' found on their victims' bodies. Our results suggest that a link may exist between postmortem signatures and two complementary appearance-demeanor types.     

The utilization of forensic science and criminal profiling for capturing serial killers

Movies and nightly television shows appear to emphasize highly efficient regimens in forensic science and criminal investigative analysis (profiling) that result in capturing serial killers and other perpetrators of homicide. Although some of the shows are apocryphal and unrealistic, they reflect major advancements that have been made in the fields of forensic science and criminal psychology during the past two decades that have helped police capture serial killers. Some of the advancements are outlined in this paper. In a study of 200 serial killers, we examined the variables that led to police focusing their attention on specific suspects. We developed 12 categories that describe how serial killers come to the attention of the police. The results of the present study indicate that most serial killers are captured as a result of citizens and surviving victims contributing information that resulted in police investigations that led to an arrest. The role of forensic science appears to be important in convicting the perpetrator, but not necessarily in identifying the perpetrator.     

Theoretical consideration of female sexual predator serial killers in the United States

Sexual predators represent the embodiment of the cultural definition of serial killing. In considering the female sexual predator serial killer, a review of the limited literature found a clear distinction between women acting alone versus in partnership. Several theories offered to explain the behavior of women in teams include shared psychotic disorder, Stockholm syndrome, posttraumatic stress disorder (PTSD), battered woman syndrome, and gender role socialization. Analysis of each with specific case examples found that gender role socialization appeared to be the most inclusive, explaining the participation of women in teams, as well as providing insight into both the criminal justice system and overall societal responses to female serial killers, as well as violent women more generally. The analysis concludes by describing the implications of the above speculations within the realms of prevention, treatment, and research, specifically concluding that women can commit willful violence and that low base rates should not impede attempts to understand and prevent such violence.     

The associations between abuse characteristics in child sexual abuse: a meta-analysis

Child sexual abuse (CSA) is a general term describing a wide range of events that vary in characteristics such as the victim’s age of onset, relationship to the perpetrator, abuse quantity, degree of contact, and use of force. To investigate correlations and provide information on the clustering of these characteristics, the present meta-analysis included data from 14,494 sexually abused individuals from 62 empirical peer-reviewed studies and doctoral theses. The results showed that victims of intrafamilial abuse were younger than victims of extrafamilial abuse. More force was used in abuse including higher degrees of physical contact. Intrafamilial abuse and early onset of abuse showed no statistically significant associations with either use of force or closer physical contact. Abuse was more frequent and/or committed over a longer time period when it (a) featured more contact or force, (b) involved a relative as a perpetrator, or (c) commenced when the child was younger. The associations were weak to moderate in strength.     

Paths to destruction: the lives and crimes of two serial killers

Although research into the phenomenon of serial murder has revealed that serial killers frequently do not fit the initially described paradigm in terms of their physical and psychological profiles, backgrounds, and motives to kill, the media continues to sensationalize the figures of such killers and the investigators who attempt to analyze them on the basis of aspects of their crimes. Although the so-called "typical" profile of the serial murderer has proven accurate in some instances, in many other cases the demographics and behaviors of these killers have deviated widely from the generalized assumptions. This report details two unusual cases in which five and eight murders were committed in upstate New York. The lives and crimes of these offenders illustrate the wide spectrum of variations in the backgrounds, demographics, motivations, and actions witnessed among serial murderers, and highlight the limitations and dangers of profiling based on generalities.     

Serial killers with military experience: applying learning theory to serial murder

Scholars have endeavored to study the motivation and causality behind serial murder by researching biological, psychological, and sociological variables. Some of these studies have provided support for the relationship between these variables and serial murder. However, the study of serial murder continues to be an exploratory rather than explanatory research topic. This article examines the possible link between serial killers and military service. Citing previous research using social learning theory for the study of murder, this article explores how potential serial killers learn to reinforce violence, aggression, and murder in military boot camps. As with other variables considered in serial killer research, military experience alone cannot account for all cases of serial murder. Future research should continue to examine this possible link.     

Subgaleal hematoma in child abuse

The mother brought her 31/2-year-old son to a paediatric clinic as his forehead was swollen and bluish in appearance. She was unable to give any explanation for this lesion. Clinically it was noted that a very visible and also palpable, doughy swelling was present both in the forehead as well as the hard skull areas. Some hours later, a massive bilateral periocular haematoma appeared. Whilst X-rays were unable to provide any diagnostic help, the sonographic examination of the skull carried out on the same day revealed an extensive subgaleal haematoma. This phenomenon is described in radiological literature as "scalping" and is caused by the use of considerable, blunt violence against the head (shear stresses, e.g. by pulling at the hair). The mother's boyfriend later confessed forceful pulling of the hair.     

Female serial killers in the United States: means,motives, and makings

Most studies that have focused on female serial killers (FSKs), although informative, have examined limited sample sizes. We consulted mass media reports of demographics, motives, methods, mental health, and victim characteristics of 64 FSKs who committed their crimes in the US from 1821 to 2008. Consistent with other studies, our data showed that FSKs were typically White, educated, have been married, and held a caregiving role (e.g. mother, health care worker). Nearly 40% of FSKs in this sample experienced some form of mental illness. Their most common motive for murder was financial gain, and their most common method of killing was poisoning. FSKs knew all or most of their victims, and most were related to their victims. In all cases, FSKs targeted at least one victim who was a child, elderly, or infirm – those who had little chance of fighting back. We interpret these killers’ behaviors from clinical and evolutionary angles.     

Psychosocial dynamics of child abuse

The problem of child abuse warrants steadfast social concern and attentive study by social scientists, forensic scientists, and mental health professionals. What moves adults to physically abuse children entrusted to their care? In the present inquiry, an overview of a substantial body of the literature is organized by exploring three dimensions of abuse: the parental relationship, the psychopathology of abusive parents, and the psychodynamics of motivation. None of these dimensions taken alone provides a satisfactory understanding of the phenomenon of abuse. An integrative model is offered wherein child abuse is regarded as a function of three general factors: stresses on the parent, ego weaknesses of the parent, and vectors that direct the parent's violent impulses against the child.     

Pseudoabuse--the misdiagnosis of child abuse

When a patient's problem is judged to be the result of child abuse and it is not, considerable harm may be done to the child, his parents, and the doctor-parent relationship. The case histories of 15 children who were thought to be abused are reviewed and their correct diagnoses are presented. Overdiagnosing the battered child syndrome can be as harmful as failing to consider it.     

Decision-making in child abuse and neglect

Social attachment theory can be of value in examining the wide variety of abuse and neglect situations that come to the attention of authorities. We consider evaluation of the parent-child relationship as a crucial part of the judicial process. We have suggested parameters that can be used to evaluate the relationship. We have outlined some of the more common distortions in this relationship that have, in our experience, been associated with the mistreatment of children. The use of social attachment theory has been of great help in understanding the emotional reactions of the many children we have seen for evaluation and treatment. The theory also serves as a potential guide for improvements in social policy. If we are more sensitive to the psychological world of these children, we will be better able to truly protect them.     

Childhood history of abuse and adult child abuse potential

The experience of aversive interactions within the family of origin is believed to increase the probability of parental physical child abuse. To test this hypothesis, 375 subjects were given a Childhood History Questionnaire (CHQ) and the Child Abuse Potential (CAP) Inventory. The CHQ contained a series of questions about the presence and frequency of various abusive behaviors and associated sequelae that were received and/or observed before and/or after puberty. The CAP Inventory was used to measure adult physical child abuse potential. As expected, a childhood history of physical abuse was significantly related to adult physical child abuse potential; and, as chronicity increased, so did abuse potential. The experience of physical abuse prior to puberty produced higher abuse scores than the experience of physical abuse after puberty. The study provides preliminary data indicating the childhood experience of a caring adult and / or caring friend moderates adult child abuse potential.     

The incidence of alleged sexual abuse in 603 family court cases

The conflict and animosity that sometimes accompanies child custody disputes can give rise to the propagation of allegations of child sexual abuse. To characterize the magnitude of the problem, the present study attempted to determine whether and to what extent child sexual abuse allegations predominate in family court litigation. The entire one-year caseload of a county family court docket was systematically reviewed and coded. Methodical evaluation of 603 family court files yielded base rates of pertinent allegations and other information profiling the cases. The findings did not support the contention that sexual abuse allegations are commonplace in child custody disputes. Sexual abuse allegations were made in 2% of cases in which custody or access was contested and in only 0.8% of the cases overal. Implications of the findings for future research were discussed.The authors gratefully acknowledge the assistance of the Honorable William R. Campbell and Barbara Scott, Clerk of Court for the South Carolina Fifth Judicial Circuit, as well as the contributions of Angie Newton, Frank Robinson, and Kimberly Ellis in the data collection process.     

The use of random sampling in investigations involving child abuse material

This paper presents a methodology which has been used to address two ubiquitous problems of practising digital forensics in law enforcement, the ever increasing data volume and staff exposure to disturbing material. It discusses how the New South Wales Police Force, State Electronic Evidence Branch (SEEB) has implemented a “Discovery Process”. Using random sampling of files and applying statistical estimation to the results, the branch has been able to reduce backlogs from three months to 24 h. The process has the added advantage of reducing staff exposure to child abuse material and providing the courts with an easily interpreted report. The software portion of the Discovery process is contained within the framework of Guidance software's forensic tool, EnCase^©. This is then further customised for the Discovery process by using the EnCase EnScript^© language.     

The influence of personal history of abuse and gender on clinicians' judgments of child abuse

Two extra-legal factors were examined for their influence on professionals' decisions to report child abuse: having been abused as a child oneself, and the gender of the child, the parent, and the professional. One hundred and one men and women who worked regularly with children in mental health settings rated a series of scenarios presented as cases from a protective service agency. Participants made several judgments regarding the case including the severity of the parent's behavior, the likely effect on the child, whether the situation was abusive, and whether the case should be reported to a social service agency. Despite some interpretive limitations, the results generally support the hypothesis that extra-legal factors influence the perceptions of professionals who are mandated to report a suspected incident of abuse.     

Intergenerational child abuse and coping

Many studies have investigated the consequences of child sexual abuse (CSA) but few have examined the intergenerational effects of poly- victimization and maladaptive coping. The purpose of this investigation was to examine patterns of maltreatment and maladaptive coping among second-generation CSA survivors. It is hypothesized that: (a) maternal CSA history would be associated with a higher incidence of poly-victimization and maladaptive coping and (b) experiencing more forms of abuse would mediate the relation between maternal CSA history and maladaptive coping behaviors. The method used was a chart review of 139 sexually abused females aged 12 to 17, examining maternal abuse history, maladaptive coping behaviors, and child maltreatment. The results showed that poly-victimization differed as a function of maternal CSA history but maladaptive coping did not. Experiencing more types of abuse was associated with both self-injurious behaviors and substance use. In conclusion, results support the hypothesis that second generation CSA survivors are more likely to experience poly-victimization. Future research should address how intergenerational patterns of abuse might affect presenting symptomatology and treatment outcome.
