Police Investigations (police + investigation)
Selected AbstractsSexual abuse at a Swedish daycare centre: allegations, confessions and evaluationsACTA PAEDIATRICA, Issue 8 2000F Lindblad In September 1997, sexual abuse at a Swedish daycare centre was disclosed. The suspect, a male member of the staff, admitted having abused six children. A total of 30 children were included in the police investigation. In this study, these cases were evaluated individually using a child psychiatric method. Information was collected from the police investigation and from interviews with parents. The conclusions,categorized as "abuse likely", "abuse conceivable" or "abuse uncertain",were compared with the children's own reports, the legal evaluations and the confessions of the suspects. Conclusions: The correspondence of child reports with child psychiatric evaluations was fairly high, indicating that child reports may serve as a good screening indicator of abuse. There was little agreement between child psychiatric evaluations and legal decisions, which were based on the reports of suspects. Some differences may be explained by varied methodology, definitions and criteria. Others reflect real differences in opinion. Our study illustrates the need to establish legal criteria for statements from pre-schoolers if such evidence is to constitute the basis of a ruling without a confession. Studies comparing professional psychological assessments of children's statements about sexual abuse with independent data stand out as an important line of research for the future.

Data from 386 solved vehicle thefts committed by 193 offenders were analysed using Jaccard's, regression and Receiver Operating Characteristic analyses to determine whether objectively observable aspects of crime scene behaviour could be used to distinguish crimes committed by the same offender from those committed by different offenders. The findings indicate that spatial behaviour, specifically the distance between theft locations and between dump locations, is a highly consistent and distinctive aspect of vehicle theft behaviour; thus, intercrime and interdump distance represent the most useful aspects of vehicle theft for the purpose of case linkage analysis. The findings have theoretical and practical implications for understanding of criminal behaviour and for the development of decision-support tools to assist police investigation and apprehension of serial vehicle theft offenders.

[source] Characteristics of spousal homicide perpetrators: a study of all cases of spousal homicide in Sweden 1990,1999CRIMINAL BEHAVIOUR AND MENTAL HEALTH, Issue 2 2004Professor Henrik Belfrage PhD Background In Sweden 20 000 cases of assault against women are reported to the police every year. Method All data on the perpetrators of spousal homicide in Sweden between 1990 and 1999 were investigated (n = 164). A control group of all other perpetrators of homicide in Sweden during the same period, i.e. cases of homicide not committed in the context of spouse violence (n = 690) was used. All verdicts, as well as all material in the police investigations, including interviews with all of the police investigators, were analysed. Copies of police examinations of the suspects, and forensic reports from the autopsies, were also examined. Data on all registered criminality were collected from the National Police Register, and in cases where the perpetrators had been subject to forensic psychiatric examinations, those reports were obtained from the Swedish National Board of Forensic Medicine. In addition, the Psychopathy Checklist: Screening Version scores were rated from the forensic psychiatric examinations. Results There was a four times higher suicide rate among the spousal homicide perpetrators (24%, n = 40) compared with the perpetrators in the control-group (6%, n = 39, chi-squared = 55,42df = 1 , p < 0.001). Consequently, suicidal ideation must be considered as an important risk factor for spousal homicide. In 79% of the cases the spousal homicide perpetrators were subject to forensic psychiatric examinations. All except 5% were diagnosed with at least one psychiatric diagnosis, and 34% were sentenced to forensic psychiatric treatment. If it is assumed that the psychiatric morbidity was high in the 24% of the perpetrators who committed suicide, then 80% of all perpetrators of spouse homicide during the study period can be characterized as mentally disordered. ,Psychopathic' perpetrators, who generally are over-represented in most violent criminality, were comparatively uncommon. Only seven (4%) in the study group met the diagnostic criteria for psychopathy as measured with the PCL:SV. Discussion The group of spouse killers studied here fits the dysphoric/borderline group of spouse assaulters. This is a group that may benefit from treatment. Perhaps police officers could help identify this kind of spouse assaulter before a fatality occurs. Copyright © 2004 Whurr Publishers Ltd. [source] Let's find the evidence: an analogue study of confirmation bias in criminal investigationsJOURNAL OF INVESTIGATIVE PSYCHOLOGY AND OFFENDER PROFILING, Issue 3 2010Eric Rassin Abstract People involved in criminal proceedings (e.g. police officers, district attorneys, judges, and jury members) may run the risk of developing confirmation bias, or tunnel vision. That is, these parties may readily become convinced that the suspect is guilty, and may then no longer be open to alternative scenarios in which the suspect is actually innocent. This may be reflected in a preference for guilt-confirming investigation endeavours, as opposed to investigations that are aimed at confirming, or even excluding, alternative scenarios. In three studies, participants read a case file, and were subsequently instructed to select additional police investigations. Some of these additional endeavours were guilt-confirming (i.e. incriminating), whereas others were disconfirming (i.e. exonerating). Results suggest that additional investigation search was guided by an initial assessment of the suspect's guilt (Study 1). Furthermore, participants' tendency to select incriminating investigations increased with increased crime severity, and with the strength of the evidence present in the case file. Finally, the selection of incriminating investigations was associated with conviction rates (Study 3). However, in general, participants did not favour incriminating endeavours. That is, in the three studies, the percentages of selected incriminating endeavours did hardly or not exceed 50%. Copyright © 2010 John Wiley & Sons, Ltd. [source] Facilitating eyewitness memory in adults and children with context reinstatement and focused meditationJOURNAL OF INVESTIGATIVE PSYCHOLOGY AND OFFENDER PROFILING, Issue 2 2006Laura Hammond Abstract 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 closed questions to levels above those achieved by controls, although those in the CR condition produced significantly more correct responses than those in the FM condition. However, only those in the CR group displayed elevated levels of confidence in relation to incorrect responses on closed questions. Implications for the possible use of such procedures are discussed.

[source] Investigating the nature of expressiveness in stranger, acquaintance and intrafamilial homicidesJOURNAL OF INVESTIGATIVE PSYCHOLOGY AND OFFENDER PROFILING, Issue 3 2005Stephanie K. Last Abstract This study explores the role of the victim,offender relationship in the dynamics of homicide, by examining the crime scene behaviour of 25 intrafamilial, 30 acquaintance and 27 stranger homicide offenders (n = 82). Six crime scene variables were examined: ,Weapon from the scene', ,Excessive wounding', ,Facial trauma', ,Multiple wounds to a single area', ,Post-mortem activity' and ,Manual violence'. The first objective was to identify whether these variables could be combined to form a partially ordered scale of expressiveness. The second was to examine whether the nature of this expressive crime scene varied according to the victim and offender relationship. It was hypothesised that the intrafamilial homicides would be characterised by a more expressive crime scene. This was examined by Partial Order Scalogram Analysis which supported the hypothesised link between the level of expressed emotion evident in the crime scene and the nature of the victim,offender relationship. Further analysis on the individual variables revealed that the best single predictor of the relationship between victim and offender was the presence of multiple wounding. These findings are discussed both as contributing to a theoretical understanding of the emotional salience of crime scene actions when killing a family member, and in practical terms in relation to the significance of these variables for both police investigations and clinical interventions with homicide perpetrators.
