The fallibility of forensic science consultation is an ongoing and major justice concern. Prospective peer‐reviewed forensic consultation has over 10 years of application in American criminal and civil courts, adapting from the traditional oversight of teaching hospitals, rules of evidence and discovery, conventions of testimony of expert witnesses, and attorneys' overall trial strategy. In systematizing heightened oversight, this process ensures greater accountability in forensic science consultation. The integration of peer reviewers' complementary expertise and experience enhances the sophistication and overall quality of assessment. Forensic examination frequently involves the interface of different specialties. Multidisciplinary peer review augments expert proficiency with that of professional peers having different vantage points from relevant scientific disciplines. This approach ensures greater sophistication of a case inquiry, built‐in accountability, and streamlined processes when multiple experts are necessitated. Here, the authors present examples of several cases and the primary and secondary benefits of this collaborative, rigorous, cross‐disciplinary exercise.  相似文献

Previous research has demonstrated significant sexual dimorphism in friction ridge skin characteristics. This study uses a novel method for measuring sexual dimorphism in finger ridge breadths to evaluate its utility as a sex estimation method from an unknown fingerprint. Beginning and ending in a valley, the width of ten parallel ridges with no obstructions or minutia was measured in a sample of 250 males and females (N = 500). The results demonstrate statistically significant differences in ridge breadth between males and females (p < 0.001), with classification accuracy for each digit varying from 83.2% to 89.3%. Classification accuracy for the pooled finger samples was 83.9% for the right hand and 86.2% for the left hand, which is applicable for cases where the digit number cannot be determined. Weight, stature, and to a lesser degree body mass index also significantly correlate with ridge breadth and account for the degree of overlap between males and females.  相似文献

Illegal alcoholic beverages are often introduced into market using cheap technical alcohol, which is contaminated by denatonium benzoate (Bitrex) of very small concentration. Bitrex is the most bitter chemical compound and has to be removed before alcohol consumption. The home‐made methods utilize sodium hypochlorite to disintegrate particles of denatonium benzoate in alcohol and to remove bitter taste before trading. In this experimental studies, we propose a novel method that detects in a fast way the remnants of denatonium benzoate in dubious alcohol samples by Raman spectroscopy. This method applies a portable Raman spectrometer of excitation wavelength 785 nm and utilizes the effect of surface‐enhanced Raman spectroscopy (SERS) to recognize the suspected alcoholic beverages. High effectiveness (over 98%) of YES/NO classification of the investigated samples was observed when the nonlinear algorithm support vector machine (SVM) was exploited at carefully adjusted detection parameters. The method can identify illicit alcohol within minutes.  相似文献

Forensic practitioners and crime laboratories regularly collect and analyze fingernail evidence; however, the best techniques for processing such evidence have not been established. In this study, numerous aspects of fingernail evidence processing—collection of exogenous cells, transportation, purification of DNA, and STR analysis—were analyzed using fingernails harboring applied blood or epithelial cells from scratchings. Autosomal STR mixtures resulted when fingernails were soaked or swabbed, while scrapings rarely generated mixtures but exhibited allelic dropout. Y‐STRs yielded single source profiles, with scrapings again showing dropout. A silica‐based kit extraction recovered significantly more exogenous DNA than did organic extraction, neither of which was affected by nail polish. Swabbing nails in succession resulted in some cross‐contamination from exogenous material, while transporting nails together did not, although there was loss of exogenous cells. Optimized nail processing produced complete Y‐STR profiles of male volunteers from female fingernails following scratchings.  相似文献

Research on traumatic brain injury among inmates has focused on comparing the rate of traumatic brain injury among offenders to the general population, but also how best to screen for traumatic brain injury among this population. This study administered the short version of the Ohio State University Traumatic Brain Injury Identification Method to all male inmates admitted into Indiana state prisons were screened for a month (N = 831). Results indicate that 35.7% of the inmates reported experiencing a traumatic brain injury during their lifetime and that these inmates were more likely to have a psychiatric disorder and a prior period of incarceration than those without. Logistic regression analysis finds that a traumatic brain injury predicts the likelihood of prior incarceration net of age, race, education, and psychiatric disorder. This study suggests that brief instruments can be successfully implemented into prison screenings to help divert inmates into needed treatment.  相似文献

An algorithm incorporating multidetector computed tomography (MDCT), digital radiographs, and external examination was used to triage cases for noninvasive or complete autopsy after a natural disaster. The algorithm was applied to 27 individuals who died during or soon after the earthquake that struck the Republic of Haiti on January 12, 2010. Of the 27 cases reviewed, 7 (26%) required a complete autopsy to determine cause and manner of death. In the remaining 20 (74%), cause and manner of death were determined with a reasonable degree of medical certainty after review of circumstances, an external examination, and postmortem imaging by MDCT and digital radiography (noninvasive autopsy). MDCT was particularly useful in detecting skeletal fractures caused by blunt force injury which were not evident on digital radiographs. The algorithm incorporating postmortem MDCT can be useful in the triage of human remains for autopsy after a natural disaster.  相似文献

Sequencing mitochondrial DNA hypervariable regions I and II (HVI and HVII) is useful in forensic missing person and unidentified remains cases. Improvements in ease and sensitivity of testing will yield results from more samples in a timely fashion. Routinely, amplification of HVI and HVII is followed by Sanger sequencing using the BigDye^® Terminator v3.1 Cycle Sequencing kit (Applied Biosystems) using 4 μL of ready reaction mix (RRM). Each sequencing reaction is then purified through column filtration before capillary electrophoresis. Using lower amounts of RRM (2 μL or 1 μL) and purification using BigDye^® XTerminator^? (Applied Biosystems) instead of columns showed no loss of sequence length and increased the quality and the sensitivity of testing, allowing HVI and HVII typing from mitochondrial genome equivalent to 125 fg of nuclear DNA, or 100 pg of HVI/HVII amplicons. Using this methodology, testing can be completed in 1 day, and the cost of testing is reduced.  相似文献

While forensic studies have reported higher than community rates of mental disorders in imprisoned populations, few studies have focused on attention‐deficit/hyperactivity disorder (ADHD) in these subjects. The aim of this study was to investigate ADHD prevalence among young French male prisoners. A specific diagnostic interview (Conners' Adult ADHD Diagnostic Interview for DSM‐IV, CAADID) was used. Correlations between ADHD, subsyndromal ADHD, and criminal features were investigated. 11% of young male prisoners among 93 male subjects aged 18–35 years met the criteria for actual ADHD, and 17% met those for childhood ADHD. Considering ADHD and subsyndromal ADHD, prevalence was about 43% in adulthood. ADHD and subsyndromal ADHD in adulthood were significantly associated with a higher number of imprisonments and a younger age at first arrest. It could be advisable to better identify subjects with ADHD symptoms among prison populations.  相似文献

This paper examines Louisiana’s habitual offender statute and the role of a sociologist as a mitigation expert/criminologist in a specific case. The paper includes a summary of the habitual offender statute; the literature/theories used by the sociologist in his testimony; the trial judge’s decision; and the decision of the three-judge panel of the appellant court, particularly the minority opinion. The case has been returned to the district court for re-sentencing and the trial judge is under no obligation to accept the panel’s decision; but in practice must justify any lenient sentence. The use of sociology as mitigation in criminal cases generally is discussed. The author has worked in over 300 criminal cases since 1988, most of which were capital murder, but also include second-degree murder, manslaughter, armed robbery, rape, and habitual offender hearings.  相似文献

The rich body of prison literature suggests that imprisonment is a painful experience, even though imprisonment does not appear to uniformly cause psychological deterioration. However, psychological adjustment and its variations remain poorly defined in the literature. The aim of this study is to provide a framework for understanding psychological adjustment and describe patterns of adjustment of prisoners who are close to their release. Thirty semi‐structured interviews were conducted with male and female prisoners. Even in the same prison environment, prisoners showed a wide variety of patterns of psychological adjustment, characterised by differences in coping ability and functioning, mental health, subjective well‐being and outlook on the future.  相似文献
