The Use of Laser Microdissection in Forensic Sexual Assault Casework: Pros and Cons Compared to Standard Methods 下载免费PDF全文

Sexual assault samples are among the most frequently analyzed in a forensic laboratory. These account for almost half of all samples processed routinely, and a large portion of these cases remain unsolved. These samples often pose problems to traditional analytic methods of identification because they consist most frequently of cell mixtures from at least two contributors: the victim (usually female) and the perpetrator (usually male). In this study, we propose the use of current preliminary testing for sperm detection in order to determine the chances of success when faced with samples which can be good candidates to undergo analysis with the laser microdissection technology. Also, we used laser microdissection technology to capture fluorescently stained cells of interest differentiated by gender. Collected materials were then used for DNA genotyping with commercially available amplification kits such as Minifiler, Identifiler Plus, NGM, and Y‐Filer. Both the methodology and the quality of the results were evaluated to assess the pros and cons of laser microdissection compared with standard methods. Overall, the combination of fluorescent staining combined with the Minifiler amplification kit provided the best results for autosomal markers, whereas the Y‐Filer kit returned the expected results regardless of the used method. 相似文献

Experiencing child sexual abuse (CSA) can have enormous consequences for the victims. However, reporting rates are comparably low. Thus, it is essential to consider the wishes and needs of disclosing CSA victims in order to develop measures that can improve the disclosure and reporting of CSA. We analysed data of a subsample of n?=?394 victims of contact CSA from a representative victim survey (N?=?11,428) conducted by the Criminological Research Institute of Lower Saxony, Germany, in 2011. Overall, 76% of the victims disclosed their CSA experience to somebody. However, only 14% of the cases were made known to law enforcement agencies. Of the disclosing victims, only one-third was believed and 43% reported that the disclosure led to no further consequences. Overall, being believed as well as supported by the victims’ family proved to be crucial. Implications are discussed against the background of previous research. 相似文献

Little is known about overall psychological distress in paedophiles who are not formally involved with the criminal justice system. Since knowledge in this context could help to optimise intervention efforts, this study aimed to examine the association between distress as measured with the Brief Symptom Inventory (BSI) and preference- and offence-related variables in a sample of N?=?455 men self-reporting sexual interest in children, of whom 402 were diagnosed as paedophiles. Results showed that 59% reported clinically relevant levels of distress, with paedophiles being significantly more distressed than teleiophiles. A regression analysis revealed that a paedophilic preference and prior detection were relevant predictors for distress. However, past offending behaviour had no impact and the major part of variance could not be explained. The results suggest that paedophilia is associated with distress, but other factors influence whether a paedophilic man is distressed on a clinically significant level. 相似文献

Although the Sexual Violence Risk-20 (SVR-20) is widely used, its psychometric properties have only been investigated in a limited number of studies. This study explored the factor structure of the SVR-20 and examined its psychometric properties. Confirmatory factor analysis (CFA) was used to examine the fit of the original three-domain model of the SVR-20. The CFA showed that the original structure was not satisfactory. Exploratory principal components analysis (PCA) was conducted in search of a more optimal factor structure. Psychometric properties (i.e., internal consistency, predictive value, and convergent validity) of both the original domains and alternative factors were investigated. The PCA and subsequent CFAs pointed in the direction of an alternative, more optimal three-factor solution. The three alternative factors were labeled as Antisociality, Sexual deviance, and Problematic thinking and produced better internal consistency coefficients than the original domains. However, the validity of the SVR-20 was modest and no evidence was found indicating that the alternative factors were better in this regard as compared to the original domains. Despite the overall superiority of actuarial measures in predicting recidivism, the structured professional judgment of the SVR-20 proved to be more predictive of sexual, violent, and general recidivism than its actuarial scoring method. 相似文献

Despite important progress in knowledge about interview ‘best practice’ with child victims, few studies had yet evaluated the impact of interviewers’ personal characteristics on adherence to these ‘best practice’. This study was designed to determine whether interviewers’ personal characteristics are associated with adherence to a structured interview protocol (National Institute of Child and Human Development), the use of open-ended questions and the amount of details provided in children’s responses during investigative interviews with alleged victims of child sexual abuse. 114 interviews were scored from 13 police investigators after they followed a one-week training program. Results showed that experience, emotional intelligence, Extraversion, Agreeableness, Conscientiousness and Neuroticism were related with adherence to the protocol and ratio of open-ended questions. Cognitive abilities were related to the amount of details obtained from the child. Generalized estimating equations were used to compare relative contribution of each variable. These findings raise questions about how investigative interviewers are selected and trained. 相似文献

Coarctation of the aorta (CA) is diagnosed mainly in pediatric patients, and therapy is conservative if asymptomatic, but surgical treatment is required if advanced arterial hypertension is present. Moderate to severe forms contraindicate any type of physical activity requiring cardiac effort. Here, we describe the first documented death of an apparently healthy 35-year-old woman because of cardiac tamponade by rupture of an aortic aneurysm, possibly related to congenital CA, prolonged use of oxymetazoline hydrochloride, and physical and/or emotional stress during sexual activity. Our patient was asymptomatic for classical CA symptoms. The patient's breathing difficulties likely in hindsight were due not so much to nasal congestion, but rather to an ineffective oxygenation of the blood from the abnormal heart. In an attempt to treat the "nasal disease," the patient ingested chronic and excessive doses of decongestants, aggravating her fatal disease. The danger of inhaling large doses of nasal decongestants without an appropriate medical indication is highlighted here. 相似文献

The male-specific, human Y-chromosomal short tandem repeats (Y-STRs) are very useful in forensic analysis and human evolution studies. The authors report two sexual crime cases in which the perpetrators were successfully traced using Y-haplotype screening of local patrilineages followed by autosomal STR typing. First, several main local patrilineages from local cases were investigated using Y-STR haplotyping, aimed to find the pedigrees whose haplotypes were identical or similar to those of the crime scene samples. Then, several key suspects were defined from the screened pedigrees, and autosomal STR typing was performed to identify the perpetrator of the crime. The application of Y-haplotype screening of local patrilineages followed by autosomal STR typing in these two cases demonstrates its usefulness for solving sexually related crimes in certain populations. 相似文献

The note considers the decision of the Court of Appeal in Maga v The Trustees of the Birmingham Archdiocese of the Roman Catholic Church and analyses the application of the status based risk approach to vicarious liability in that case. It considers its application outside of the area of clerical sexual abuse, and also the role in vicarious liability of job conferred status which materially increases the risk of the commission of a tort, or helps to facilitate a tort. 相似文献
