Mighty Morphin’ age progression: how artist,age range,and morphing influences the similarity of forensic age progressions to target individuals

When children go missing, authorities sometimes release age progressed images that are intended to approximate the person's current appearance. The current studies measured the influence of the range between the time when the child went missing and the age portrayed in the age progression on the similarity between the progressions and current images of the targets. Experiment 1 examined whole face images and Experiment 2 examined internal features only. Eight artists were recruited to produce progressions at three age ranges. Also included were averaged (morphed) images made of progressions of the same individual at a given range by different artists. Progressions across shorter ranges produced images more similar than those across longer ranges, and target comparisons yielded higher similarity ratings than foil comparisons. Although there was much variability among artists, the morphed images performed better than the average rating given to all age progressions.     

Reuniting families: an online database to aid in the identification of undocumented immigrant remains

The Reuniting Families project attempts to aid federal, state and local agencies currently working towards the identification of deceased undocumented immigrants. This initiative has created a distributed on-line database, accessible by public officials and private citizens interested in searching for missing individuals based on both phenotypic and genotypic characteristics. This broad effort includes the exhumation of individuals from geographically disparate pauper graves, the classification of their physical characteristics, and the cataloging of observed metric traits in a local relational database, to include associated articles of possession and related metadata. Concurrent with the documentation of physical forensic evidence is the analysis of mitochondrial DNA sequences. Computational techniques and scoring parameters are applied to automate the process of discovery and identification as well at to preserve information on the missing. The result is a prototype knowledge base that may serve as a model for future efforts in international forensic science collaborations.     

AMBER Alerts: Are School-Type Photographs the Best Choice for Identifying Missing Children?

We investigated how well adults could recognize the faces of children when they differed in appearance from photographs shown in an alert. College students in three studies saw a mock AMBER Alert while watching a television show. The children appeared either well-groomed with positive affect (as in a school photograph) or disheveled with poor affect (as abducted children might appear). Recognition accuracy and confidence were significantly lower when the faces differed in appearance from the alert displayed during the television show. Thus, AMBER Alerts may be more effective if they are accompanied by more than one type of photograph of a missing child, particularly if a photograph is shown in which the child does not appear well-groomed and happy.     

Development of a methodology for the standardisation and improvement of ‘Smartphone’ photography of patterned bruises and other cutaneous injuries

Human bite-mark analyses can play a prominent role in forensic case investigations, including those involving sexual assault. High-quality photographs routinely secure a link between a bite-mark and an individual's dentition. Access to around the clock forensic photography, however, is often limited, resulting in delay and/or missed opportunities to record valuable evidence. The emergence of Smartphone high-quality photographic technology now provides a previously unimagined opportunity to gather timely forensic photographic evidence. Problems can arise, however, due to the relatively poor quality of the photographs, as a result of many of those taking photographs having received little or no forensic photography training. This study compares unassisted photography with assisted photography, by a specifically developed camera application (App), to provide a standardised method for taking forensic photographs. An App, written in Java, was hosted on the Google Android Operating System, on a Samsung Galaxy SII Smartphone. Twenty-four volunteers participated in a study to photograph a pseudo bite-mark using three methods, (1) unassisted (as a control), (2) assisted by an ABFO No.2 right-angled photographic reference scale and (3) assisted by the App. The App, method (3), was shown to consistently outperform methods (1) and (2), demonstrating greater standardisation and precision (p < 0.001). Analysis of the data showed the extent to which acquiring an accurate photograph depends on the image being orthogonal to the camera. It appears likely that the relatively inaccurate photographs acquired by methods (1) and (2), were as a result of deviation from the plane, orthogonal to the bite-mark. Therefore, the App was successful in ensuring that the camera was both orthogonal and at an appropriate distance, relative to the bite-mark. Thus, the App enhanced the abilities of non-experts to acquire more accurate photographs and created the potential to significantly improve the quality of forensic photographs.

The Bite Mark Standard Reference Scale--ABFO No. 2

A scale of spatial reference for bite mark photography has been developed and evaluated. The scale incorporates both linear and circular graduations to meet the diverse needs of practicing forensic odontologists in the rectification and measurement of photographically recorded bite marks. Its unique L-shaped configuration ensures accurate scaling in both the vertical and horizontal directions and facilitates the gridding of photographs to correct for distortional errors created by oblique camera angles. This paper describes the design and constructional features of the scale and offers guidelines for its effective application to bite mark photography.     

The diversity of adult dental patterns in the United States and the implications for personal identification

Few would argue about the individuality of dental radiographs for forensic identification, but when an antemortem/postmortem comparison is based strictly on dental treatment notes and/or charts it becomes less certain. In the past, attempts to validate the high diversity of dental patterns created by combinations of missing, filled, and unrestored teeth have been based on unfounded statistical assumptions. The goal of this research is to present a statistically valid method of assessing dental pattern diversity for the identification of missing individuals. Empirical observation of large reference datasets was found to be the best technique for assessing dental diversity. This technique is nearly identical to the procedure used for mitochondrial DNA casework. For the research presented in this paper, two large datasets were used, one composed of U.S. military personnel and one composed of U.S. civilians. Dental patterns were found to be very diverse on a scale that is comparable to mtDNA. In addition, it was found that the diversity values remain very consistent regardless of the level of detail present in the treatment records. Overall, combinations of missing, filled, and unrestored teeth were found to be very individualistic and an excellent source for forensic identification.     

Application of mtDNA sequence analysis in forensic casework for the identification of human remains

In four forensic cases of unidentified skeletal remains investigated in the last year, we were able to attach three to missing persons. In one case we could show that the discovered bone sample did not fit to a missing child. The method for mitochondrial DNA analysis for the routine identification of skeletal remains was established in our institute by typing bone samples of defined age obtained from Frankfurt's cemetery. Reproducible results were obtained for bones up to 75 years old. For analysis the bone samples were pulverised to fine powder, decalcified and DNA was extracted. From the DNA we amplified a 404-bp fragment from HV-1 and a 379-bp fragment from HV-2 of the mtDNA control region. After sequencing of the PCR products, the results were compared to the Anderson reference sequence and to putative maternal relatives.     

The foster family in Poland,a custodial and educational environment (XX – the early XXI centuries)

ABSTRACT

A thorough study of the sources made it possible to conduct a retrospective analysis as well as outline normative and legal principles of the foster family in Poland as one of the main forms of child custody in the XX – early XXI centuries rooted in national traditions and social legacy. Foster family formation and early functioning indicate that its value depends on who is entrusted with a child to care for, what child is to be placed in foster care, what kind of support a foster family could expect, what control is exercised over it. The second half of the XX – the early XXI centuries mark the evolution of the legal and regulatory framework underlying foster care, one of the main institutional forms of child custody in Poland. It appears that the foster family provides a child with proper living conditions and a favourable environment for its education and socialisation, closest possible to those in a natural family. To this end, the state is to make sure that potential foster parents are properly trained. The development of foster care speeds up in the 1970’s and 1990’s. We have discovered that at the turn of the century, foster family functioning, provision of care and adequate conditions for a child’s development and upbringing etc. are defined by the social policy of the state. Of great significance for the international community is the Polish experience regarding the requirements for foster family candidates, children’s placement in such families, material assistance, foster parent salary calculations; the amount of money biological parents must pay for their child’s placement in a foster family. In modern Poland the foster family is an important social institution which promotes the development of a child deprived of parental care and is prioritized over other institutional forms of care.     

A multifaceted,multijurisdictional, multiagency,and multidisciplinary approach to investigating unidentified and missing persons cases in Australia

Currently, there are approximately 750 unidentified human remains and 2500 long-term missing persons in Australia. The Australian Federal Police National DNA Program for Unidentified and Missing Persons (Program) is using a multifaceted, multijurisdictional, multiagency, and multidisciplinary approach in a dedicated effort to identify these unknown deceased persons, scientifically link them to known missing persons, and provide answers to their families. The nationally coordinated Program provides its police, forensic, and coronial stakeholders with a suite of contemporary forensic technologies, databases, and experts to forensically examine the skeletonised remains and recover post-mortem data for comparison to the available ante-mortem data for each missing person. Through a number of physical and virtual public outreach activities, families with missing relatives have been encouraged to provide vital ante-mortem forensic information, records, and samples to aid the identification process. To date, this unique Program has assisted to resolve a number of unidentified and missing persons cases from both historical and contemporary contexts, using a combination of genetic and non-genetic techniques, and local and national databases. The centralisation of Program capabilities, expertise, and resources to conduct this type of unique and challenging casework is proving to be the most effective and efficient way to generate investigative leads, identify human remains, and resolve long-term missing persons cases in Australia.     

Multi-agent scavenging patterns in Hawai‘i: A forensic archaeological and skeletal case study

Knowledge of the behavior of local fauna can aid forensic investigators in developing awareness of site formation processes. In Hawai‘i, little has been published on the effects of feral domestic pig (Sus scrofa) and feral domestic dog (Canis familiaris) scavenging and bone dispersal on field recovery and laboratory observations. In this Pacific tropical setting, the most consequential terrestrial taphonomic agents are pigs and dogs, both in terms of hard tissue modification and dispersal of remains across the landscape. In 2017, an archaeologist discovered the remains of an unidentified decedent on the island of Kauaʻi, State of Hawai‘i during a cultural resource management survey. Subsequently, a forensic recovery team in conjunction with Kaua‘i police and crime scene investigators used archaeological techniques, including pedestrian survey, tape-and-compass, and GPS mapping, to map and recover the remains. A feral pig trail transected various areas of the recovery site and corresponded with the distribution pattern of recovered skeletal material, including both the main concentration more broadly dispersed skeletal elements. While much of the skeleton was present, missing or unrecovered skeletal elements are consistent with expectations based on existing literature. Much of the postmortem bone deformations were characteristic of marks related to feral dog and/or feral pig scavenging. These results assisted local investigators in deciding the manner of death, as well as providing the family with an accounting of the decedent’s remains for burial. Thus, forensic anthropologists and archaeologists need to understand and develop knowledge of local animal behavior to recover and interpret human remains of medicolegal significance.     

Bayesian networks for DNA-based kinship analysis: Functionality and validation of the GENis missing person identification module

GENis is a recently published open-source multi-tier information system developed to run forensic DNA databases. It relies on a Bayesian Networks framework and it is particularly well suited to efficiently perform large-size queries against databases of missing individuals. In this contribution we present a validation of the missing person identification capabilities of GENis. To that end we introduce fbnet, a free-software package written in the R statistical language that implements the complete GENis functionality to perform kinship analysis based on DNA profiles. With the aid of fbnet, we could validate likelihood ratios against estimations draw with Familias and forrel (two well-recognized R packages for kinship quantification) for complex pedigrees provided by the Argentinian reference databank (Banco Nacional de Datos Geneticos, BNDG). We found that our methodological approach presented an excellent performance in terms of accuracy and computation times.     

Expert Testimony Regarding Child Witnesses: Does It Sensitize Jurors to Forensic Interview Quality?

Does expert testimony on forensic interviews with children help adults distinguish between poorly conducted and well-conducted interviews? This study evaluates the effects of social framework expert testimony regarding child witnesses in a case involving allegations of child sexual abuse. A 2 (Expert Testimony: present or absent) × 3 (Child Forensic Interview Quality: poor, typical, or good) × 2 (Child’s Age: 4- or 10-year-old) factorial design was used to examine whether expert testimony is prejudicial or beneficial to jurors (N = 463). The results revealed that, without expert testimony, mock jurors did not consider the forensic interview quality when reaching a verdict. However, with expert testimony, mock jurors were more likely to render guilty verdicts if the interview quality was good versus poor. Further expert testimony increased mock jurors’ knowledge about child witnesses. These findings suggest that expert testimony related to the impact of interview techniques on the reliability of children’s reports may assist fact-finders in evaluating child abuse cases.     

Failure of anthropometry as a facial identification technique using high-quality photographs

Anthropometry can be used in certain circumstances to facilitate comparison of a photograph of a suspect with that of the potential offender from surveillance footage. Experimental research was conducted to determine whether anthropometry has a place in forensic practice in confirming the identity of a suspect from a surveillance video. We examined an existing database of photographic lineups, where one video image was compared against 10 photographs, which has previously been used in psychological research. Target (1) and test (10) photos were of high quality, although taken with a different camera. The anthropometric landmarks of right and left ectocanthions, nasion, and stomion were chosen, and proportions and angle values between these landmarks were measured to compare target with test photos. Results indicate that these measurements failed to accurately identify targets. There was also no indication that any of the landmarks made a better comparison than another. It was concluded that, for these landmarks, this method does not generate the consistent results necessary for use as evidence in a court of law.     

Biology, childhood trauma, and murder: rethinking justice

This article reviews recent findings in the developmental neurophysiology of children subjected to psychological trauma. Studies link extreme neglect and abuse with long-term changes in the nervous and endocrine systems. A growing body of research literature indicates that individuals with severe trauma histories are at higher risk of behaving violently than those without such histories. This article links these two research areas by discussing how severe and protracted child abuse and/or neglect can lead to biological changes, putting these individuals at greater risk for committing homicide and other forms of violence than those without child maltreatment histories. The implications of these biological findings for forensic evaluations are discussed. Based on new understanding of the effects of child maltreatment, the authors invite law and mental health professionals to rethink their notions of justice and offender accountability, and they challenge policymakers to allocate funds for research into effective treatment and for service delivery.     

Tests of one Brazilian facial reconstruction method using three soft tissue depth sets and familiar assessors

Facial reconstruction is a method that seeks to recreate a person's facial appearance from his/her skull. This technique can be the last resource used in a forensic investigation, when identification techniques such as DNA analysis, dental records, fingerprints and radiographic comparison cannot be used to identify a body or skeletal remains. To perform facial reconstruction, the data of facial soft tissue thickness are necessary. Scientific literature has described differences in the thickness of facial soft tissue between ethnic groups. There are different databases of soft tissue thickness published in the scientific literature. There are no literature records of facial reconstruction works carried out with data of soft tissues obtained from samples of Brazilian subjects. There are also no reports of digital forensic facial reconstruction performed in Brazil. There are two databases of soft tissue thickness published for the Brazilian population: one obtained from measurements performed in fresh cadavers (fresh cadavers' pattern), and another from measurements using magnetic resonance imaging (Magnetic Resonance pattern). This study aims to perform three different characterized digital forensic facial reconstructions (with hair, eyelashes and eyebrows) of a Brazilian subject (based on an international pattern and two Brazilian patterns for soft facial tissue thickness), and evaluate the digital forensic facial reconstructions comparing them to photos of the individual and other nine subjects. The DICOM data of the Computed Tomography (CT) donated by a volunteer were converted into stereolitography (STL) files and used for the creation of the digital facial reconstructions. Once the three reconstructions were performed, they were compared to photographs of the subject who had the face reconstructed and nine other subjects. Thirty examiners participated in this recognition process. The target subject was recognized by 26.67% of the examiners in the reconstruction performed with the Brazilian Magnetic Resonance Pattern, 23.33% in the reconstruction performed with the Brazilian Fresh Cadavers Pattern and 20.00% in the reconstruction performed with the International Pattern, in which the target-subject was the most recognized subject in the first two patterns. The rate of correct recognitions of the target subject indicate that the digital forensic facial reconstruction, conducted with parameters used in this study, may be a useful tool.     

DNA identification of skeletal remains by investigator’s intuition

In June 2006 a decapitated woman was found in a parking area of the motorway in the area of Prato (Florence). Since the body was beheaded and no victim’s documents or objects were present at the crime scene, identification at that time was impossible. However, DNA profile from woman’s bones were collected. In the same year (2003), a mother had reported her daughter's disappearance but the two events were not related at that time. About ten years later the mother’s DNA profile was finally acquired for a genetic identification of another girl’s body found in the Ferrara area. These genetic profiles were completely discordant. All these genetic comparisons were carried out on behalf of the prosecutors of the cities involved in the findings of the bodies and in the disappearance complaints, but due to the lack of a database the events remained disconnected. In January 2017, the head of the scientific police of Prato who had followed the investigation and questioned the mother of the missing girl found about ten years later, suggested to the magistrate to order the comparison of the mother's DNA with the genetic profile of the bones found in 2006. This comparison finally allowed the identification of the missing daughter.This story highlights the importance of having forensic DNA database to search for missing persons and how the investigator's intuition can play a key role in resolving criminal cases. In fact, databases of unknown bodies and relatives of missing persons were created in Italy as a part of national DNA database just at the beginning of 2018.     

The garcia de la paz

According to the famous economist and Nobel prize winner Amartya Sen women have a significant biological advantage over men. Despite this fact women do not always live longer. In today's third world, but also in some areas in Europe at the end of the 19th and the beginning of the 20th century we find so-called excess female mortality. In this paper we examine child mortality in The Netherlands in general and gendered patterns of child mortality in particular. The focus is on differential mortality patterns by gender for infants, older children, and young adults up to age 20 in the second half of the 19th century. The analysis takes place at three levels. We start off with an exploration of sex differentials in mortality at the national level, based on the existing literature. We next examine gender differentials in mortality at the level of several Dutch communities, in the region called Twente, focussing on the differences between the city and the countryside. The final part of the analysis focuses on the micro level of the individual and his or her family in the rural community of Lonneker located in the Twente region. In this part of our study we make use of longitudinal individual level data which are analysed with event history methodologies. Our analysis clearly demonstrates that young women and girls in The Netherlands were not always in a position to fully capitalise upon their greater biological advantage and suffered instead considerable excess mortality. Especially in the rural parts of the country girls had lower survival chances. The individual level analysis confirms the importance of sex in explaining child and adolescent mortality. These gendered mortality risks can however not be attributed to social and economic household characteristics. The analysis also shows that, when death came, it literally affected the entire family. This phenomenon, better known under the label ‘death clustering’, may have been an effect of parental incompetence.
