Serial Domestic Abuse in Wales: An Exploratory Study Into its Definition,Prevalence, Correlates,and Management

Analysis of information held by police, probation, and third-sector organizations in Wales about 100 domestic abuse perpetrators, along with 16 practitioner interviews, provides the empirical context for a discussion of the problem of “serial domestic abuse.” Despite increased concern over the harm caused by serial abusers, different definitions and recording systems prevent a reliable estimation of the problem. This exploratory study suggests that the offending profiles of serial abusers are heterogeneous, and recommends that approaches aimed at reducing the harm caused by the “power few” domestic abusers incorporate information about serial alongside repeat and high-risk offending.     

DNA Recovery From Tape-Lifting Kits: Methodology and Practice

In the case of suspicious deaths, the technique of 1:1 taping is often used in Belgium. It consists of affixing a large number of adhesive tapes to the body of the victim. It is conventionally aimed at obtaining microtraces (e.g., fibers, hair) and is usually not used for DNA analysis. However, in some cases, DNA analysis of certain areas of interest identified on the 1:1 taping material can offer a last resort solution. The four-step method that is described in this article involves the selection of areas of interest on the body (Step 1), the selection of the corresponding tapes (Step 2), the decontamination of the tapes (Step 3), the selection of areas of interest on the tapes, for DNA sampling (Step 4). The method is illustrated by its successful application in four murder cases. In each case, DNA profiles of good quality could be identified, including profiles of persons different from the victim.

Murder, Extramarital Affairs, and the Issue of Probative Value

A paper previously published in Law and Human Behavior by D. Davis and W. C. Follette (2002) argued that certain "profiling" characteristics commonly admitted into court have little or no probative value. They argued that this is especially likely to be true when the characteristic used as evidence (e.g., having an extramarital affair) is rather common in the population whereas the act in question (e.g., a man murdering his wife) is rare. Their analysis has prompted a strong response by Friedman and Park and by Kaye and Koehler with a rejoinder by Davis and Follette (all three follow this paper in this issue of Law and Human Behavior). This paper describes some of the nature of this controversy.     

美国刑法中的重罪谋杀罪规则评析

重罪谋杀罪是英美刑法中比较特殊,并引起很多批评和质疑的罪名。目前,美国大部分州的刑法仍保留有该罪名,但其适用范围和条件受到越来越多的限制,实际上被限于在实施重罪过程中故意或过失造成死亡结果的情形。由于该罪名的设置仍具有一些积极意义且限制了适用范围,尽管存在比较严厉的批评之声,但绝大多数州的刑法仍然保留了重罪谋杀罪规则,短期内没有被废除的迹象。     

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.     

The Homicide–Suicide Phenomenon: Findings of Psychological Autopsies

Homicide–suicide represents a single episode of violence which may decimate an entire family. This study aimed to further describe motives and context of these tragedies. Psychological autopsies were completed for 18 homicide–suicide cases in Dallas, Texas. This included postevent interviews with surviving family members and review of police and coroner records. Two‐thirds of perpetrators had made either verbal or written threats prior to the homicide–suicide. A simplified typology describing victim–perpetrator relationship and motive type is suggested for future studies and clinical ease. Two‐thirds of perpetrators fell into the category of Intimate‐Possessive, most of whom were depressed men who were abusing substances and undergoing separation. Additional categories included Intimate‐Ailing, Filial‐Revenge, Familial‐Psychotic, and Friend‐Psychotic. Further, implications from this psychological autopsy study regarding risk assessment include use of collateral interviews regarding threats and past violence.     

Predicting Serial Killers' Home Base Using a Decision Support System

The effectiveness of a geographical decision support tool (Dragnet) forlocating the base of serial offenders was compared across 570 modelscomprised of a range of negative exponential functions, buffer zonecomponents, and normalization parameters. The models were applied to thebody disposal locations within each series for 70 U.S. serial killers. Twonormalization parameters were compared for all functions. The test ofeffectiveness was a specifically defined measure of search cost. Whenapplied to the Dragnet predictions it was found that the specially developednormalization parameter (QRange) produced the optimal search costs. Theoptimal search cost was also found to be for a function that did not includeany buffer zone. The optimal, average search cost across the whole samplewas 11% of the defined search area. Fifty-one percent of the offendersresided in the first 5% of the search area, with 87% in the first 25%. Allresided in the total defined search area. These results support thepotential for operational tools using such procedures as well ascontributing to our understanding of criminal's geographicalbehavior. The applicability to other forms of serial crime is considered.     

Mass murders in Germany – classification of surviving offenders based on the examination of court files

Personality, psychopathology, and motives of 44 surviving offenders committing mass murder in Germany over 25 years (1984–2009) were analyzed using court files and psychiatric expertises. Initially, 123 mass murders in Germany were detected in the time period 1980–2010 (inclusive deceased offenders). Using a data entry form based on ViCLAS (Violent Crime Linkage Analysis System), we categorized the 44 surviving mass murderers into three prototypes using the ‘TwoStep Cluster’-method (separation of the offenders in different groups depending on their similarity of specific items): 1. Narcissistic or aggressive men suffering from addiction or affective disorder, committing mass murder out of rage/hate when being intoxicated by alcohol, 2. Psychotic offenders with schizophrenia and comorbid substance abuse. 3. Aggressive, narcissistic or anxious adolescents, half of them suffering from affective disorder or ADHD, committing mass murder out of rage/hate. Not included are such events where the offenders died and therefore no court files or psychiatric expertises were available. Classification and subtyping of the offenders’ personalities and psychopathological conditions might help to improve the chances for an early detection of persons at risk.
