Fatal penetrating abdominal injury by a metallic projectile

Penetrating abdominal injury is often a life-threatening condition, which is mainly associated with inflicted injuries. Fatal self-inflicted sharp force abdominal injuries too have been reported in the literature. Inadvertent penetrating abdominal injuries are a rarity and are caused by sharp objects of low-velocity and often nonmissile-type. A 27-year-old male factory worker was brought dead to the emergency department with an alleged history of sustaining abdominal injury by a sharp metal projectile while working on a metal cutting grinder. Autopsy observations were consistent with the history of inadvertent penetrating injury. Our case reports a fatal missile-type inadvertent sharp force trauma over the abdomen with intestinal perforation, a relatively uncommon scenario in occupational/workplace settings. The present case report describes the significance of the death scene visit and corroborating the medical findings with investigating agencies. This case further emphasizes on the need for adopting proper safety measures at the workplace.     

A novel method for cyanide quantification in human whole blood using ion chromatography with amperometric detection and its application to cyanide intoxication cases

Cyanide is a highly toxic agent that has been frequently used for suicide in South Korea. It is also used in various industrial fields, such as metal plating, in which many accidental cyanide intoxications have occurred. To overcome the disadvantages of conventional cyanide analysis methods, a simple and fast method for the analysis of cyanide in whole blood using ion chromatography (IC) with amperometric detection was developed in this study. Whole blood samples were deproteinized, diluted, and analyzed using an IC–amperometric detection system. The limits of detection and quantitation were 0.1 and 0.2 mg/L, respectively. The method showed good linearity in the range of 0.2 to 50 mg/L with R² > 0.99. The intra- and inter-assay precision and accuracy values were <10%. The established method was successfully applied to analyze whole blood samples from three cyanide intoxication cases.

A mixed DNA profile controversy revisited

Semaan et al. (J Forensic Res, 2020, 11, 453) discuss a mock case “where eight different individuals [P₁ through P₈] could not be excluded in a mixed DNA analysis. Even though … expert DNA mixture analysis software was used.” Two of these are the true donors. The LRs reported are incorrect due to the incorrect entry of propositions into LRmix Studio. This forced the software to account for most of the alleles as drop-in, resulting in LRs 60–70 orders of magnitude larger than expected. P₁, P₂, P₄, P₅, and P₈ can be manually excluded using peak heights. This has relevance when using LRmix which does not use peak heights. We extend the work using the same two reference genotypes who were the true contributors as Semaan et al. (J Forensic Res, 2020, 11, 453). We simulate three two-donor mixtures with peak heights using these two genotypes and analyze using STRmix?. For the simulated 1:1 mixture, one of the non-donors’ LRs supported him being a contributor when no conditioning was used. When considered in combination with any other potential donors (i.e., with conditioning), this non-donor was correctly eliminated. For the 3:1 mixture, all results correctly supported that the non-donors were not contributors. The low-template 4:1 mixture LRs with no conditioning showed support for all eight profiles as donors. However, the results from pair-wise conditioning showed that only the two ground truth donors had LRs supporting that they were contributors to the mixture. We recommend the use of peak heights and conditioning profiles, as this allows better sensitivity and specificity even when the persons share many alleles.     

Metric forensic anthropology decisions: Reliability and biasability of sectioning-point-based sex estimates

Subjective decisions make human cognitive processes more susceptible to bias and error. Specifically, research indicates that additional context biases forensic anthropologists’ morphological analyses. To address whether metric analyses are also subject to bias, we conducted a pilot study in which 52 experienced osteologists measured a difficult-to-classify human femur, with or without additional contextual information. Using a metric sectioning-point sex-estimation method, participants provided a sex estimate for individual skeletal element(s) and, when given multiple elements, the combined skeletal assemblage. Control group participants (n = 24) measured only the femur. In addition to the femur, bias group participants (n = 28) either measured a female humerus and viewed a female-biasing photograph (n = 14) or measured a male humerus and viewed a male-biasing photograph (n = 14). We explored whether the experts in the different groups would differ in: (1) femoral measurements; (2) femoral sex-estimation conclusions; and (3) final sex-estimation conclusions for the skeletal assemblage. Although the femoral measurements and femoral sex estimates were comparable across groups, the overall sex estimates in the female-biased group were impacted by contextual information—differing from both the control and male-biased groups (p < 0.001). Our results demonstrate that cognitive bias can occur even in metric sex-estimation conclusions. Specifically, this occurred when the metric data and single-element sex estimates were synthesized into an overall estimate. Thus, our results suggest that metric methods are most vulnerable to bias when data are synthesized into an overall conclusion, highlighting the need for bias countermeasures and comprehensive statistical frameworks for synthesizing metric data to mitigate the effects of cognitive bias.     

论税收法定原则的司法化

税收法定原则的司法化是“全面落实税收法定原则”的必然要求,而传统理论疏漏了其中的司法内涵,导致税收法定原则出现了作为基本原则却难以直接指导和适用于税收司法的悖论。鉴于税收法定原则与罪刑法定原则的亲缘性,发展相对成熟的罪刑法定原则可以为完善税收法定原则的内涵构成提供三点启示。同时,结合税收法定原则的固有内容,税收法定原则的司法化应当在适用范畴上向司法原则扩围,价值层次上向实质正义升华,法定程度上向相对法定适当松动。据此,三路并进,税收法定原则的司法内涵得以全面、系统的补漏。税收法定原则司法内涵的完善将有助于打破税收法定原则司法化的理论困局,助推“全面落实税收法定原则”法治图景的实现。     

Lethal small bowel obstruction due to pica

Up to 25% of institutionalized patients with cognitive deficiencies display pica-like behavior, with an estimated annual incidence of small bowel obstruction of 2%. We present a case based on the forensic autopsy of a 41-year-old woman who died as a result of a missed diagnosis of small bowel obstruction after ingesting a foreign body. The case underlines the importance of precaution when treating patients with cognitive deficiency and/or language deficits and gastrointestinal symptoms. In such cases, it is important to employ a liberal threshold for radiological investigations and, if possible, obtain a medical history from a person close to the patient.     

Psychopathy and Female Gender: Phenotypic Expression and Comorbidity; A Study Comparing a Sample of Women Hospitalized in Italy's Maximum Security Facility with Women Who were Criminally Sentenced and Imprisoned,

Various studies have shown that women with psychopathy tend to commit crimes that are less violent than those of psychopathic men. The present study was designed to address the influence of psychopathy on the crimes committed by female offenders. A national sample of female offenders found NGRI or of diminished responsibility and at risk for criminal recidivism (OPG patients) was compared with a sample of female offenders who were convicted and imprisoned. Results of this comparison between the two groups of female offenders indicate that psychopathy is a transversal psychopathological dimension which may or may not be associated with other mental disorders. In both samples, the most commonly reported offenses among women with high PCL‐R scores were minor offenses, not particularly violent, but they appear to be related to typical psychopathic features such as superficial charm, pathological lying, and manipulation.
