Position Effect on Facial Soft Tissue Depths: A Sonographic Investigation

The head is positioned erect for an approximation; yet most facial soft tissue depths (FSTD) used are measured from supine subjects. Depth difference might be significant, but there is a paucity of data to verify. This study compared erect and supine values for 17 landmarks from 30 healthy New Zealand (European population affinity) women (18–30 or 40–55 years) in erect then supine positions. Height, weight, and sonographic FSTD data, totaling 1020 measurements, were obtained. Three midline and seven averaged bilateral values were compared using ANOVA, p values, and Pearson's correlations. Correlative strength of age and body mass index, BMI (kg/m²), was determined by values. Results showed averaged erect and supine differences were significant for four of ten FSTDs. Between individuals, difference was various and not unidirectional. In conclusion, depth differences were observed but not all significant or unidirectional, BMI significantly influenced nine FSTD values, but age group did not.     

Nondestructive Biological Evidence Collection with Alternative Swabs and Adhesive Lifters

In forensic science, biological material is typically collected from evidence via wet/dry double swabbing with cotton swabs, which is effective but can visibly damage an item's surface. When an item's appearance must be maintained, dry swabbing and tape‐lifting may be employed as collection techniques that are visually nondestructive to substrates' surfaces. This study examined the efficacy of alternative swab matrices and adhesive lifters when collecting blood and fingerprints from glass, painted drywall, 100% cotton, and copy paper. Data were evaluated by determining the percent profile and quality score for each STR profile generated. Hydraflock^® swabs, BVDA Gellifters^®, and Scenesafe FAST? tape performed as well as or better than cotton swabs when collecting fingerprints from painted drywall and 100% cotton. Collection success was also dependent on the type of biological material sampled and the substrate on which it was deposited. These results demonstrated that alternative swabs and adhesive lifters can be effective for nondestructive DNA collection from various substrates.     

The Influence of Wood Grain on the Bullet's Ricochet Behavior

When a bullet ricochets from wood, various parameters will influence its behavior. In this study, the influence of the wood grain on the ricochet angle (β) and deflection angle (γ) is assessed. Series of five .32 Auto bullets were fired at different angles of incidence (α) on boards of six wood types. The results confirm the previously shown effect that the mean β‐angles usually exceed α and increase when α increases. Overall, the maximum mean γ occurs when the angle of wood grain (ζ), in relation to the plane of impact, lies between 30° and 75° but differs per combination of wood and α. The results show the inclination of γ toward the left or right, depending on the bullets left or right rotation while also showing that the direction of ζ can enhance or counteract this effect considerably, especially when α is close to the critical ricochet angle.     

Taphonomic Patterning of Cemetery Remains Received at the Office of the Chief Medical Examiner,Boston, Massachusetts

A sample of 49 cases of cemetery remains received at the Office of the Chief Medical Examiner, Massachusetts (OCME‐MA), in Boston was compared with published taphonomic profiles of cemetery remains. The present sample is composed of a cross section of typical cases in this region that ultimately are derived from modern to historical coffin burials and get turned over to or seized by law enforcement. The present sample was composed of a large portion of isolated remains, and most were completely skeletonized. The most prevalent taphonomic characteristics included uniform staining (77.6%), coffin wear (46.9%), and cortical Exfoliation (49.0%). Other taphonomic changes occurring due to later surface exposure of cemetery remains included subaerial weathering, animal gnawing, algae formation, and excavation marks. A case of one set of skeletal remains associated with coffin artifacts and cemetery offerings that was recovered from transported cemetery fill is also presented.     

Suicide by Shotgun in Southeastern Minnesota

Suicide by shotgun is a common method of suicide with high regional variation. We sought to describe their distinct, challenging features and provide demographic and risk characteristics. We reviewed 228 gunshot wounds autopsied at Mayo Clinic from 1994 to 2014; of these, 75 (32.9%) were shotgun wounds. All were suicides and contact range. Ages ranged from 14 to 92 years old; of these, 97% were men. The majority involved the head (70.9%), were intraoral (48.2%), and had upward (73.2%) and backward (73.2%) directionality. Next most common was the chest (21.5%), with backward (94.1%) and downward (64.7%) directionality. Four involved multiple wounds. Wadding was recovered in 16 (21.3%) cases. Six (8.0%) had a survival period. Most (66.7%) took place at home. Seventy‐one percent had a known psychiatric history; 32.4% had positive toxicology. Although contact range shotgun wounds cause severe destruction, entrance wound and other characteristic are identifiable with thorough scene, autopsy, and radiographic documentation.     

Beyond Taphonomy: Exploring Craniometric Variation Among Anatomical Material

Anatomical crania are occasionally encountered in forensic anthropology laboratories when that material is mistaken for forensically significant human remains. Using craniometric analyses and statistical measures of sample homogeneity, we determine whether anatomical material can be described as a single, homogenous group or as a diverse mix of populations. Twenty‐one interlandmark distances were collected from 85 anatomical preparations. Distance measures were calculated between all pairs using a pooled within‐sample variance/covariance matrix and then subjected to a Defrise‐Gussenhoven test between each paired distance to test whether each pair was drawn randomly from the same population. In the Defrise‐Gussenhoven analysis, twenty‐two percent (n = 66) of the 300 pairwise combinations were significant at the 0.05 level or below. The level of homogeneity suggests a majority of that material originated from the subcontinent of India or West Asia. Therefore, anatomical material can be viewed as a moderately homogenous group, but with a shared taphonomic history.     

Ricochet Behavior on Glass—Critical Ricochet Angles,Ricochet Angles,and Deflection Angles

For shooting scene reconstruction purposes, knowledge about the ricochet behavior of bullets provides valuable information. In this study, the critical ricochet angles of four cartridge types were established on plain float glass. The estimates of the critical ricochet angles varied between cartridge types and were 21.0° for .32 Auto FMJ bullets, 15.8° for 9 mm Luger FMJ bullets, 17.6° for .45 Auto FMJ bullets, and 21.3° for 9 mm Luger, Action NP bullets. The corresponding ricochet and deflection angles per incidence angle varied depending on the state of the ricocheted bullets. The mean ricochet angles are always lower than the corresponding angles of incidence, and the mean ricochet angles for the FMJ bullets with undamaged jackets are lower than those of bullets where the jacket is either damaged or the bullet partially ricocheted and partially perforated. Mean ricochet angles are lower for undamaged FMJ bullets than for undamaged Action NP bullets.     

The state of the nation: diversity and the British legal academy

In this short piece, I set out briefly what we know about the challenge of diversity in the legal academy from existing scholarship. That field, in the UK at least, is sparse. I then go on to present a snapshot of the legal academy using data from the Higher Education Statistics Agency (HESA). I do this as the start of a much larger project on diversity and the legal academy that I plan to undertake over the next year. My argument is rather simple. The diversity of the legal academy reflects neither the diversity of our law student bodies nor the diversity of the wider population. Such diversity is vital for a number of reasons. My hope is that this piece can be the start of a dialogue on an important and largely ignored topic, and that further research will be done in this area.     

On the Social Foundations for Crimmigration: Latino Threat and Support for Expanded Police Powers

Objectives

Because of the merging of immigration control and criminal justice, or “crimmigration,” state and local police increasingly drive interior immigration enforcement through the routine policing of crime. At the same time, growing evidence indicates that immigration is an ethnicity-coded issue that allows for the veiled expression of broader anti-Latino sentiments. Yet little research has examined whether public perceptions of either immigrants or Latinos influence support for police policies and practices that, in the context of crimmigration, may significantly shape immigration enforcement and, more broadly, may contribute to the subordination of Latinos. The current study addresses this research question.

Methods

The study draws on data from a recent nationally representative telephone survey and employs multivariate regression methods to evaluate whether perceptions of Latino economic and political threat are associated with support for granting police greater latitude in stopping, searching, and using force against suspects.

Results

This study provides the first evidence that, at least among Whites, perceived Latino threat is positively associated with support for expanding police investigative powers, especially the power to stop suspects based only on the way they look.

Conclusions

The results suggest that by increasing public support for aggressive policing, or, at minimum, by reducing opposition to discriminatory social controls such as police profiling, Latino threat perceptions may increase the political attractiveness and viability of crimmigration as a “solution” to the “Latino problem.”

     

An Exploratory Study of Honor Crimes in the United States

There is a lack of research on honor crimes within the United States. We used an open source search methodology to identify the victim-offender relationship and motivations for this crime within the United States. Using data collected based on the protocol for the United States Extremist Crime Database (ECDB), we identified a total of 16 honor crimes with 40 victims that occurred between January 1st 1990 and December 31st 2014 in the United States. Based on our findings, the overarching motivations for honor crimes in the United States were the perpetrator’s former partner beginning the process of separation and the westernized behavior of the victim, typically the offender’s daughter or step-daughter. Honor crimes were not limited to current/former intimate partners or daughters, as they also included the death of extended family members (e.g. in-laws, nieces, and cousins). Policy implications and directions for future research on honor crimes are discussed.
