Understanding (Mis)classification Trends of Latin Americans in Fordisc 3.1: Incorporating Cranial Morphology,Microgeographic Origin,and Admixture Proportions for Interpretation

Assigning correct population affinity to a skeleton can contribute important information to an investigation—yet recent work highlights high error rates when classifying Latinos with a traditional tool, Fordisc 3.1 (FD3). Our study examines whether misclassification trends exist, and whether these can be used to infer population affinity. We examine the relationships among ancestry, geography, and FD3 misclassifications of Latinos using canonical variate analysis and unsupervised model‐based clustering of craniometrics. Northern Mexicans appear more strongly associated with FD3 references samples with elevated amounts of European ancestry (e.g., American Blacks and Whites), while Southern Mexicans are more strongly associated with FD3 reference samples with reduced amounts of European ancestry (e.g., Guatemalans and Native Americans). FD3 classifications revealed that Latinos exhibited lower posterior probabilities when compared to other common case demographics (Whites and African Americas), even when the classification was “correct.” We make recommendations for practitioner interpretation of FD3 reports for casework.     

Competency for Chinese Handwriting and Signature Examination

Chinese characters had their root some 4000 years ago and, with the growth in population, are used by over 1.3 billion people worldwide today; it is inevitable that document examiners would encounter cases involving the examination of Chinese handwriting regardless of their location. Although there are extensive studies on the examination of English handwriting in the literature, similar studies on Chinese handwriting are relatively limited. We are seeking to explore the obstacles and challenges for a document examiner who is unfamiliar with Chinese characters to apply the principles of identification and elimination of authorship described in the literature to examine Chinese handwriting, and how can these document examiners demonstrate their competency for conducting Chinese handwriting examination. This study provides a review of the literature, compares the methodology and key features in English and Chinese handwriting examination, and describes various workshops and proficiency testing programs organized to assist document examiners seeking development in Chinese handwriting and signature examination.     

Atypical Suicide by Submachine Gun

In case of suicide, the presence of multiple entrance wounds is always suspicious. We report the case of a man who committed suicide by shooting himself three times in the chest and the skull with a submachine gun. The weapon seems to have been initially pointed in the precordium area with a lethal lesion of the proximal aorta. Two other projectiles were fired by the weapon and hit the neck and the skull of the deceased. The presence of three entrance wounds despite a first fatal wound could finally be explained by the characteristics of the weapon and wounds. Most suicides related to multiple gunshot wounds are explained by a first nonlethal shot but the use of an automatic weapon can also be found. In these last cases, medicolegal and criminalistics aspects become important in differentiating suicide and homicide.     

Comparison of Different Swabs for Sampling Inorganic Gunshot Residue from Gunshot Wounds: Applicability and Reliability for the Determination of Firing Distance

This study concentrates on samples of bare pork skin, with and without bristles, and dried bovine ribs shot with a semi‐automatic pistol to find the best methodology and sampling surface in the search for inorganic gunshot residues (IGSR). Four quadrants of known surface areas were sampled at different distances from the bullet's hole with different swabs: tapes in graphite, Leukosilk® white tape, 3M® transparent tape, and a cotton swab to assess the technique able to collect the highest amounts of IGSR with the lowest contribution of the blank. The cotton swab wet in 10% HNO₃ gave the best results. The highest amounts of IGSR, measured by ICP‐OES and MS, were detected on a surface of 3‐cm radius from the bullet's edge. The amount of metals collected decreased with the firing distance between 20 and 60 cm. The procedure was efficient for sampling different tissues like skin and bones.     

Attitudes,Perceptions, and Preferences of Individuals from Temuco (Chile) About Denture Marking

Denture marking (DM) helps identify edentulous people with different methods. Analyzing perceptions and attitudes of denture wearers would enable understanding of the practical aspects, an analysis still absent in South America. Fifty‐three individual candidates for removable dentures were instructed on disaster victim identification (DVI) and the usefulness of DM for this purpose. They were physically shown eight DM systems and a questionnaire to which they responded by highlighting preferences in those systems. Although 98.11% did not know that dentures could be marked, only 9.43% denied interest in some type of DM. The 90.57% would mark their dentures with some system, preferring the inclusion of QR codes or a micro SIM card. The proven weaknesses of DVI and propensity for disaster mean this community in Chile is an opportunity to implement DM systems. Obstacles may come not from patients but from their dentists, educational institutions, or a lack of public policies.     

A Retrospective Study of Intentional Body Dismemberment in New York City: 1996–2017

A review of New York City dismemberment cases occurring between 1996 and 2017 was conducted, which resulted in a total of 55 dismembered decedents in a 22‐year period. Annual trends indicate an average of 2.5 dismembered decedents. Additional results show that 53% of cases involved transection only, 35% involved disarticulation only, and 13% involved a combination of both. When the entire body could be accounted for, the average number of body portions per case was 5.5. Frequent locations for dismemberment were the neck, shoulders, hips, and knees. Dismemberment locations showed a general trend of anatomical symmetry. Seventy‐eight percent of the dismemberments involve disposal of body parts in an outside location. Eighty‐four percent were concealed from view with some type of covering. The findings from New York City are compared with other studies.     

The commemoration of death,organizational memory,and police culture

Police scholars document that although there is fragmentation of the so‐called “monolithic” police culture, historically consistent features of the occupational culture of police exist. By drawing on ethnographic observations in three U.S. police departments, I describe how one consistent feature of police culture—the preoccupation with danger and potential death—is maintained by the commemoration of officers killed in the line of duty. Through the use of commemorative cultural artifacts, officers and departments construct an organizational memory that locally reflects and reifies the salience of danger and potential death in policing. Furthermore, commemoration of fallen officers is not restricted to a department's own; the dead of other departments are commemorated by distant police organizations and their officers, maintaining broad, occupational assumptions of dangerous and deadly police work that transcend a single department and its localized organizational memory. Implications for the study of police culture, inequalities in policing, and police reform are considered.     

The Making and Unmaking of Feminicidio/Femicidio Laws in Mexico and Nicaragua

This article examines the contested process of law‐making related to the killing of women which resulted in the criminalization of feminicide (feminicidio) and femicide (femicidio) in Mexico and Nicaragua, two countries in which feminists engaged in legal activism to increase state accountability for gendered violence. Through comparative analysis, we demonstrate the importance of (1) the interaction between shifting local political conditions and supranational opportunities and (2) the position of feminist actors vis‐à‐vis the state and its gender regime in shaping regional variation in the making of laws concerning gendered violence. In Mexico, the criminalization of feminicidio resulted from a successful naming and shaming campaign by local feminist actors linked to litigation in various supranational arenas, and the intervention of feminist federal legislators. In Nicaragua, the codification of femicidio resulted from the state's selective responsiveness to feminist demands in a moment of narrow political opportunity within an otherwise highly consolidated regime. We also examine the unmaking of these laws through their perversion in practice (Mexico) and their intentional undermining (Nicaragua) at the hands of the state. Our analysis demonstrates how states' decisions to enact legislation against gendered violence does not occur solely because they are invested in international legitimacy, but also in response to states' shifting acceptance of the legitimacy of supranational authority itself.     

Stability and Specificity of Counterfeit Protection System Code

In this study, the stability and specificity of a counterfeit protection system (CPS) code were determined. This research involved an analysis of a counterfeit protection system code unit over time using the pattern location measurement method. We collected 379 sample sheets from 196 printers or photocopiers, covering 14 original brands, including 129 models. There was an interval of at least two months between the collections of samples from each machine. Four types of characteristics were established: CPS pattern unit, distance of the CPS unit, position of dots, size and shape of the dot. Except for the partial changes in the Xerox brand, no other brand exhibited changes over time. This implies that the CPS characteristics are stable. Meanwhile, no correlation was noted between the combinations of the characteristic systems in the collected samples, which implied strong specificity.
