The postmortem interval (PMI) of skeletal remains is a crucial piece of information that can help establish the time dimension in criminal cases. Unfortunately, the accurate and reliable determination of PMI from bone continues to evade forensic investigators despite concerted efforts over the past decades to develop suitable qualitative and quantitative methods. A relatively new PMI method based on the analysis of citrate content of bone was developed by Schwarcz et al. The main objective of our research was to determine whether this work could be externally validated. Thirty‐one bone samples were obtained from the Forensic Anthropology Center, University of Tennessee, Knoxville, and the Onondaga County Medical Examiner's Office. Results from analyzing samples with PMI greater than 2 years suggest that the hypothetical relationship between the citrate content of bone and PMI is much weaker than reported. It was also observed that the average absolute error between the PMI value estimated using the equation proposed by Schwarcz et al. and the actual (“true”) PMI of the sample was negative indicating an underestimation in PMI. These findings are identical to those reported by Kanz et al. Despite these results this method may still serve as a technique to sort ancient from more recent skeletal cases, after further, similar validation studies have been conducted.  相似文献

In jurisdictions throughout United States, thousands of sexual assault kits (SAKs) (also termed “rape kits”) have not been submitted by the police for forensic DNA testing. DNA evidence may be helpful to sexual assault investigations and prosecutions by identifying offenders, revealing serial offenders through DNA matches across cases, and exonerating those who have been wrongly accused, so it is important to understand why police are not utilizing this evidence. In this study, we applied focal concerns theory to understand discretionary practices in rape kit testing. We conducted a three‐year ethnography in one city that had large numbers of untested SAKs—Detroit, Michigan—to understand why thousands of SAKs collected between 1980 and 2009 were never submitted by the police for forensic DNA testing. Drawing upon observational, interview, and archival data, we found that while practical concerns regarding resources available for forensic analysis were clearly a factor, as Detroit did not have the funding or staffing to test all SAKs and investigate all reported rapes, focal concerns regarding victim credibility and victim cooperation were more influential in explaining why rape kits were not tested. Implications for the criminal justice system response to sexual assault and rape kit testing legislation are examined.  相似文献

The Bills of Sale Acts were enacted in Victorian times as a form of secured credit whereby ‘goods’ owned by a borrower could be assigned under the bill of sale to a lender who would have title to the goods transferred to him. The lender would then allow the borrower to retain possession of the goods in exchange for instalment payments with interest. In the twenty‐first century these bills are most commonly used as ‘logbook loans’ for vehicles with extortionate interest rates and very little protection for individual consumers. This article examines the operational background to the Bill of Sale Acts. It focuses upon particular concerns for consumers and businesses and provides critique of the registration process before examining the proposals and consultations for reform currently before the Law Commission.  相似文献

Certain family factors, including dynamics, interactions and communication patterns, experiences of intra-familial victimisation, overall functioning and attachment can increase propensities for the commission of a sexual crime and may even be linked to recidivism. However, there is an absence of research that examines factors that contribute to problematic family relationships and how youth and caregivers vary in perceptions of family relationships. The current cross-sectional research study delivered the same validated instruments to youth (n?=?46) and their caregivers (n?=?46) to determine relative perceptions of family relationships and stress. Two multiple regression models were conducted to determine factors that contribute to problematic family relationships. Youth reported greater stress scores and more problems in family relationships relative to caregivers. Stress contributed to family relationship problems for youth and caregivers, but protective factors were associated with less family relationship problems for caregivers. Treatment and research implications are discussed.  相似文献

This study examines how sex and gender are measured and operationalized in studies on criminology and criminal justice (CCJ) through content analysis of peer-reviewed journals. Despite that they are distinct and not always parallel, the terms sex and gender are often used interchangeably in CCJ research. Moreover, despite increasing recognition that gender-responsive practices are important at every stage of the criminal justice process, gender is almost exclusively measured as a male-female binary, miscategorizing and failing to properly account for those who do not fit in one of those gender identities. There are important implications for the safety of such individuals, as both victims and offenders throughout the criminal justice process, therefore it is essential that we more accurately measure gender in this field. Recommendations for improvement are addressed.  相似文献
