Sexual sadism, psychopathy, and recidivism in juvenile sexual murderersEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Juvenile sexual homicide is rare, occurring just 10-15 times a year in the United States. No study addressing how convicted juvenile sexual murderers adjust upon reentering the community exists. A safety concern, given this research gap, is the social movement afoot to abolish life sentences for juvenile offenders. If successful, then more of these offenders will be released back into society. This descriptive study examined: (1) the clinical findings and legal outcomes of 22 sexually homicidal juveniles following arrest; and (2) the relationship between post-incarceration community adjustment and the variables of sexual s...

Finding a serial burglar's home using distance decay and conditional origin-destination patterns: a test of empirical Bayes journey-to-crime estimation in the HagueEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Can we tell where an offender lives from where he or she commits crimes? Journey-to-crime estimation is a tool that uses crime locations to tell us where to search for a serial offender's home. In this paper, we test a new method: empirical Bayes journey-to-crime estimation. It differs from previous methods because it utilises an 'origin-destination' rule in addition to the 'distance decay' rule that prior methods have used. In the new method, the profiler not only asks 'what distances did previous offenders travel between their home and the crime scenes?' but also 'where did previous offenders live who offended at the loc...

Bomb threats and offender characteristics in JapanEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
This study examined telephone bomb threats and offender characteristics in Japan (N = 101). The results showed that the most frequent offenders were middle-aged men (mean 42.6 years), motivated by desire for money (46%), resentment (26%), or diversion (24%). In the case of female offenders, most were connected with the targets (83%). Categorical principle component analysis and hierarchical cluster analysis differentiated the offenders into three themes. 'Instrumental' offenders telephoned the target directly (e.g. a bank or department store), demanding money by public phone. 'Expressive/affective' offenders motivated by r...

Bayesian journey-to-crime modelling of juvenile and adult offenders by gender in ManchesterEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
This study tested the Bayesian journey-to-crime (JTC) model by gender and age for serial offenders from Manchester, England. The data were 4056 crimes committed by 171 serial offenders between 2003 and 2006. The data were subdivided by gender and age group to examine whether accuracy and precision varied by these subgroups. In general, the centre of minimum distance was found to be the most accurate measure, but the Bayesian risk and product measures were found to be the most precise measurements. The traditional 'distance decay' type of JTC function did not produce estimates that are as accurate nor as precise as the Baye...

The mathematics of geographic profilingEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
We begin by describing some of the mathematical foundations of the geographic profiling problem. We then present a new mathematical framework for the geographic profiling problem based on Bayesian statistical methods that makes explicit connections between assumptions on offender behaviour and the components of the mathematical model. It also can take into account local geographic features that either influence the selection of a crime site or influence the selection of an offender's anchor point.

Statistical modelling in the investigation of stranger rapeEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
A sample of stranger rape offences (n = 271) registered in the Dutch Violence Crime Linkage Analysis System database in the Netherlands between 1997 and 2007 was studied with the objective of developing statistical models, which give an indication of the probability of basic offender characteristics. Observable crime characteristics concerning the modus operandi, interaction between the offender and the victim, violence, precautionary measures, and sexual behaviours were selected in the dataset. Offender characteristics were selected based on their usefulness for the police organisation in narrowing the scope of a criminal...

Uniforms affect the accuracy of children's eyewitness identification decisionsEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
This study examined the possibility that wearing a uniform constitutes an authority cue that adversely affects a child's ability to make accurate eyewitness identifications. Sixty participants aged 9-10 years old witnessed a staged crime and were later asked to identify a 'burglar' from a simultaneous line-up using a 2 (uniform: present vs. absent) × 2 (target: present vs. absent) design. Children in the uniform present conditions made significantly more choices than children in the uniform absent conditions. More importantly, in the presence of a uniform, children made significantly more false identifications in target-a...

The usual and the unusual suspects: level of suspicion and counter-interrogation tacticsEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The present study investigated guilty mock-suspects' counter-interrogation tactics with respect to the disclosure of possibly self-incriminating information, specifically, to what extent the disclosure of this information was moderated by (1) the suspects' criminal experience (naïve versus experienced) and (2) the degree of suspicion directed towards the suspects (low versus high). We found that experienced (versus naïve) suspects volunteered less self-incriminating information in an initial free recall phase. In a similar vein, when asked crime-specific questions, naïve (versus experienced) suspects admitted having com...

Spatial and environmental consistency in serial sexual assaultEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
This study examines the crime patterns of 76 New Zealand serial sexual offenders in order to determine the extent to which offenders display locational consistency in their choice of crime locations. More specifically, the hypothesis was that there would be intraseries consistency in the distances travelled (spatial consistency) and the characteristics of the crime sites selected (environmental consistency) by serial sexual offenders.For spatial consistency to be tested, the distances travelled from home to offend and the criminal range for each offence series were analysed. Support was found for spatial consistency, and, ...

A position of influence: variation in offender identification rates by location in a lineupEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Researchers have identified several threats to the validity of the use of the lineup as a test of true recognition. One concern is related to the structure of the simultaneous lineup. It is argued here that a simultaneous presentation of an array nonetheless requires the viewer to undertake sequential processing of the items in the array. This sequential pattern is unlikely to be random and therefore the position of a culprit in a lineup may have a significant effect on the accuracy of witness selection. A simulated crime (snatching of a handbag) was shown to a convenience sample of 84 undergraduates aged between 18-23 yea...

When should evidence be disclosed in an interview with a suspect? An experiment with mock-suspectsEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The question of whether to disclose evidence to a suspect early on, or later, in an interview is often of critical importance for police officers' interviewing strategies. To shed light on this issue, an experiment was conducted in which 95 participants each committed a mock-theft as a hidden 'witness' observed them. A statement from the witness was presented to them during a subsequent interview in which they were 'suspects'. The time at which this evidence was disclosed to participants, and the evidence strength, was manipulated. Each participant was randomly assigned to one of four conditions; Early Weak, Early Strong, ...

The child verbal competence effect in court: a comparative study of field investigative interviews of children in child sexual abuse casesEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The purpose of this study is to compare field investigative interviews of children (FIIC) with three different legal outcomes in child sexual abuse cases: (i) insufficient evidence to proceed (IEP); (ii) convictions; or (iii) acquittals by the court. One hundred FIIC were divided into one of the three outcome possibilities. Amongst the female interviewees older than 10 years, there were no cases of acquittals and the convicted cases were over-represented. The children's response to open questions was found to be the main difference between the three FIIC outcomes. The responses to these open questions were 1.9 and 2.3 time...

The paper summarises the main findings obtained in a wide study on the construction of deviant actions' narratives. In this paper, we focused on two topics: both topics are crucial to suggest new directions in investigative psychology. Narratives provide investigative psychologists with new sets of tools to define criminal profiles, such as narrative profiling. This paper deals with a qualitative investigation undertaken by collecting narrative interviews. These interviews were conducted with 34 prisoners held in two penal institutes in Rome and their goal was to reveal the typical form of constructing accounts taken in a ...

'The witness who saw, /he left little doubt': a comparative consideration of expert testimony in mental disability law cases in common and civil law systemsEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The question of how courts assess expert evidence - especially when mental disability is an issue - raises the corollary question of whether courts adequately evaluate the content of the expert testimony or whether judicial decision making may be influenced by teleology ('cherry picking' evidence), pretextuality (accepting experts who distort evidence to achieve socially desirable aims), and/or sanism (allowing prejudicial and stereotyped evidence). Such threats occur despite professional standards in forensic psychology and other mental health disciplines that require ethical expert testimony. The result is expert testimo...

Is there a future for investigative hypnosis?Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Since its heyday in the 1970s and 1980s, hypnosis as an investigative procedure has declined in popularity such that many experts now consider it to be more a liability than a useful forensic tool. Indeed, in the US, a majority of the states follow a per se exclusion rule, prohibiting any memories retrieved during or after hypnosis from being introduced into evidence. In this paper, factors contributing to the demise of investigative hypnosis are re-examined. It is concluded that a per se exclusion rule is overly inclusive, but it is advisable for investigators to avoid using hypnosis when other, less contentious alternati...

The effects of labelling, expert testimony, and information processing mode on juror decisions in SVP civil commitment trialsEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Expert witnesses offering testimony in sexually violent predator civil commitment trials may use diagnostic labels that are either familiar (e.g. 'psychopath') or unfamiliar (e.g. 'paraphilia') to jurors. Using predictions based on cognitive experiential self-theory, we explored the influence of testimony type (clinical versus actuarial) and diagnostic label (psychopath versus paraphilia) on jurors motivated to adopt either an experiential processing mode (PM; in which heuristic cues may be strongly relied upon) or an analytic rational PM. Consistent with previous research, our results indicated that when given a psychopat...

Methodological considerations of determining dominance in multidimensional analyses of crime scene behaviours and offender characteristicsEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Aimed at critically examining how offenders and offences are conceptualised, Investigative Psychology has seen a substantial increase in studies of crime scene behaviours and offender characteristics using multidimensional scaling (MDS) analyses that build thematic models of crime scene behaviours based on the co-occurrence variables and then testing the frameworks by determining if cases are dominant in a single thematic region. Although methods have been developed, issues that arise from using different methods and the effect on the results obtained have never been thoroughly discussed. Framed in the context of the evolu...

Entrepreneurship, police leadership, and the investigation of crime in changing timesEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Entrepreneurship, or more importantly, entrepreneurial behaviour, is not a subject one normally associates with policing per se. By considering this slippery subject in relation to police leadership styles and how they influence the investigation of crime, this essay opens up considerations of organisational theory within the rubric of investigative psychology. The tying of the meaning of being an entrepreneur into the dominant narrative of police leadership opens up fruitful lines for empirical enquiry. This is achieved via an auto-ethnographic focus. This is important because such work is currently lacking in the fields ...

Weapons used by juveniles and adult offenders in sexual homicides: An empirical analysis of 29 years of US dataEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
This study underscores the importance of analyses of specific types of murderers. In comparison with homicide arrestees, those arrested for sexual murder were more likely to be male, less likely to be black, and about as likely to be under 18. Consistent with previous literature, sexual murderers in this study were more likely to use personal and close contact weapons than firearms and other more distant methods of killing. Several significant differences emerged in weapons selected to kill different victim types between juvenile and adult offenders. Findings with respect to weapon selection by offender age groups are cons...

Post-offence characteristics of 19th-century American parricides: An archival explorationEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Using archival records from the New York Times and the Chicago Tribune, 1851-1899, the current project examines the post-offence characteristics of 19th-century American parricides. Post-offence behaviours of 100 parricide offenders were gathered. Results indicate that post-offence behaviours of parricide offenders can be thematically classified into those that reflect a continuity of violence, attempts to cover up the crime, and unusual behaviours. The implications of post-offence behaviours of parricide offenders in the context of law, mental illness, and criminological theory are discussed. Copyright © 2009 John Wiley ...

Geographical profiling obscene phone calls - a case studyEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
This study focused on crimes with no physical crimes sites (i.e. no physical contact occurred between the victim and the offender). A single offender made obscene phone calls to 86 children during the years 1999-2000 in the south of Sweden. The locations in which obscene phone calls were received were analysed in a geographical profiling system (Dragnet) to see whether it could provide a map that showed the most likely area the offender would reside in. The purpose of this study was to explore whether geographical software such as Dragnet can be used by investigators of crimes with no physical crime locations. The result s...

Psychopathy is a personality disorder characterised by affective, interpersonal, antisocial, and lifestyle elements. Studies of the association between psychopathy (e.g. as operationalised in the Psychopathy Checklist - Revised) and criminal behaviour suggest that police interviewers and interview advisors would benefit from an understanding of how psychopathic suspects are likely to behave during investigative interviews. Approaches to the identification of psychopathic characteristics in suspects are considered with reference to the P-Scan screening tool and possible indicators of psychopathic characteristics in serious ...

Predicting the behaviour of offenders with personality disorder: issues for investigative psychologyEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
This paper explores the extent to which the diagnosis of personality disorder is valid and reliable, whether such a diagnosis conveys useful information of predictive value to forensic psychology, and thus, the extent to which such a diagnosis may be of use in investigative psychology. It argues that the diagnostic criteria are of questionable reliability, validity, and utility. Using a recently developed model of the psychological underpinnings of the problematic thoughts, emotions, and behaviours encompassed by the term 'personality disorder', it argues that such problems emerge from psychological processes that are part...

A cognitive load approach to lie detectionEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
We present two lie detection approaches based on cognitive theory. The first approach, 'measuring cognitive load', assumes that the mere act of lying generates observable signs of cognitive load. This is the traditional cognitive lie detection approach formulated by Zuckerman, DePaulo, & Rosenthal (1981). The second approach, 'imposing cognitive load', was developed by us (Vrij, Fisher, Mann, & Leal, 2006) and goes one step further. Here, the lie detector attempts to actively increase the differences between lying and truth telling by introducing mentally taxing interventions. We assume that people require more cognitive r...

The school shooting/violent video game link: causal relationship or moral panic?Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
In the last 10 years, following the incidence of serious acts of school violence - particularly multiple homicides on school campuses - much attention has focused on the potential causal role of violent video game exposure.

This paper argues that such claims are faulty and fail to acknowledge the significant methodological and constructional divides between existing video game research and acts of serious aggression and violence.

Despite the popular perception that criminal investigations are often solved through the collection of objective or scientific evidence, most cases submitted for prosecution rely on confessions by suspects. Surprisingly, very little is known about which techniques are effective at eliciting admissions from guilty suspects, and in turn, which might be considered to be coercive. In the current study, 200 mock jurors (in Australia) were asked to rate the acceptability of 13 common police interviewing techniques (such as pointing out contradictions, minimisation, silence, etc.).

From marine ecology to crime analysis: Improving the detection of serial sexual offences using a taxonomic similarity measureEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Jaccard has been the choice similarity metric in ecology and forensic psychology for comparison of sites or offences, by species or behaviour. This paper applies a more powerful hierarchical measure - taxonomic similarity ([Dgr]s), recently developed in marine ecology - to the task of behaviourally linking serial crime. Forensic case linkage attempts to identify behaviourally similar offences committed by the same unknown perpetrator (called linked offences). [Dgr]s considers progressively higher-level taxa, such that two sites show some similarity even without shared species. We apply this index by analysing 55 specific o...

The use of a linkage analysis as evidence in the conviction of the Newcastle serial murderer, South AfricaEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The linking of a series of crimes to one individual has always been problematic, especially in the absence of eyewitness or forensic evidence.

This paper examines the use of a linkage analysis report as evidence during the trial of the Newcastle serial murderer in South Africa. The linkage analysis examined the circumstances of the crime, modus operandi, and signature behaviour of the offender, to come to the conclusion that all the offences were co...

Fifty children, aged between 4 and 7 years, underwent a sequential photo line-up procedure in order to identify a man they had met the previous day. Half of the participants engaged in a pre-procedure gameplay with the female interviewer. It was hypothesised that the game would stimulate rapport building and would ultimately result in an increased performance during the line-up procedure. The beneficial effect was indeed observed, but only for the male participants. This finding suggests that gameplay may be a fruitful strategy to decrease child witness discomfort and to increase participation. Copyright © 2006 John Wiley...

Co-offending and the choice of target areas in burglaryEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Using data on residential burglaries and residential burglars in The Hague, this study addresses the issue of whether solitary offenders choose their target areas differently from the way offender groups do. It is hypothesised that, in general, burglars are attracted to neighbourhoods that are nearby their homes, nearby the city centre, affluent, physically accessible, and characterised by social disorganisation. In addition, differences between solitary burglars and co-offending burglar groups regarding the strength of these criteria are assessed. The results support the postulated relevance of physical accessibility and ...

Facilitating eyewitness memory in adults and children with context reinstatement and focused meditationEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
This study examined the comparative efficacy of two brief techniques for facilitating eyewitness memory in police investigations. Adult and child participants (N = 126; 64 children and 62 adults) who had viewed a videotape of a crime were subsequently tested for their memory of the event following either a focused meditation procedure (FM, derived from hypnotic interviewing techniques), a context reinstatement procedure (CR, a component of the cognitive interview), or a control procedure (no memory facilitation instructions). For both adults and children, the FM and CR procedures enhanced performance on both open-ended and...

Spatial patterns of Indian serial burglars with relevance to geographical profilingEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Earlier studies in Western countries have shown remarkably consistent spatial patterns in serial offenders, mainly for serious crimes notably serial killing and rape, but also (although with less clear patterns) for burglary. The universality of such spatial patterns are of theoretical interest in contributing to our understanding of criminal spatial behaviour and have practical significance for the possibility of using geographic profiling in developing countries. As such, burglars in India provide a particularly interesting test of the generality of the observed spatial consistencies. Information was therefore obtained o...

A comparison of the efficacy of different decay functions in geographical profiling for a sample of US serial killersEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Many studies have shown that distributions of the distances that offenders travel in the commission of their offences are typically characterised by a decay function. However, there are few empirical comparisons of the different mathematical functions which may characterise such distributions. Further, there has been little consideration of what different forms of function may reflect about the underlying factors and psychological processes governing this aspect of the journey to crime. With the increasing use of geographical profiling systems which incorporate decay functions into their calculations, it is particularly of...

Human versus machine: a comparison of the accuracy of geographic profiling methodsEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The current article addresses the continuing debate as to the accuracy of geographic profiling methods in predicting the location of serial crime offenders. In particular, the research addresses whether spatial distribution methods and humans using simple heuristics are as accurate at predicting home locations of offenders as more complex algorithm-based methods such as RIGEL, DRAGNET, and Crimestat. Using a random sample of solved serial crimes, the research found that predictions by human judges and spatial distribution methods performed equally as well as more complex algorithm-based methods. In addition to a discussion...
