Forensic anthropology in the 1990s.

Forensic anthropology has undergone considerable change over the past 10 years. Today it is utilized by most law enforcement, coroner, and medical examiner systems. The techniques for determination of age at death, sex, race, and stature from skeletal remains have been modified and greatly expanded. The role of the forensic anthropologist within a medicolegal context is much broader than in previous years. In addition to establishing individual identity, forensic anthropologists are now consulted for trauma analysis, facial reconstruction, photographic superimposition, determination of time interval since death, and crime-scene recovery. Not all physical anthropologists are forensic anthropologists. Qualified individuals are certified, through rigorous examination, by the American Board of Forensic Anthropology. A list of board-certified forensic anthropologists may be obtained through the American Academy of Forensic Sciences.     

Forensic age diagnostics of living people undergoing criminal proceedings

In the German-speaking area, recent years have seen a rapid growth of the need for forensic age estimations. Such need arises, for example, if no verified information on the age of a person suspected of a criminal offence is available; the issue at question in terms of criminal law is whether the person concerned has reached the age of criminal responsibility and whether general criminal law in force for adults is to be applied. The relevant age tresholds in criminal proceedings are 14, 18 and 21 years of age. According to recommendations of the Study Group on Forensic Age Diagnostics, a forensic age estimate should consist of a physical examination, an X-ray of the hand, and a dental examination which records dentition status and evaluates an orthopantomogram. In addition, a radiological or CT examination of the clavicles is recommended to establish whether a person has attained 21 years of age. The present article addresses the influence of ethnic origin on the examined developmental systems.     

Contributions of Ellis R. Kerley to forensic anthropology.

Ellis R. Kerley (1924 to 1998) represents an important figure in the history of American forensic anthropology. In research, he is best known for pioneering the microscopic approach to the estimation of age at death from human bone. A university professor for 22 years. Kerley also served as Scientific Director of the Army identification laboratory in Hawaii and worked on many forensic cases. He was a leader in the formation of the Physical Anthropology section of the AAFS and the American Board of Forensic Anthropology and held many offices within the AAFS, including President from 1990 to 1991.     

The forensic examination of structural fires in Victoria,Australia: Decision-making processes and impact on judicial outcomes

There is a body of published research that has evaluated the contribution of forensic science to the criminal justice system, but many disciplines of forensic science remain unexplored in this regard. The aim of this study was to examine the contribution that forensic fire examination services provide to criminal investigations and court processes in arson cases. Forensic fire examination services differ in a number of ways to the disciplines covered in previous research on the impact of forensic evidence on justice outcomes. Forensic fire examinations involve a combination of scene examination and laboratory analyses, and the results can provide critical evidence of whether an incident that has occurred is a criminal offence (i.e. whether a fire has occurred as the result of an act of arson). Forensic fire examination is also a discipline that has faced challenges and undergone development in recent decades regarding its scientific basis and the issue of contextual bias. In this study, data were collated for 273 structural fires that were examined by the forensic fire services in Victoria, Australia. In this jurisdiction, scene and laboratory forensic services are delivered within short time frames with a focus on providing impartial scientific and investigative services to assist criminal investigations conducted by police. The current dataset was highly skewed in terms of criminal justice outcomes and was not suitable for conducting the planned statistical analyses. Nonetheless, the pattern of findings obtained suggested that the inclusion of forensic evidence which supported the prosecution of arson may be associated with an increased likelihood of suspects being charged and defendants found guilty. Examination of the decision-making process of the forensic fire examiners has provided insight into the variety of evidence that is considered by forensic experts in reaching the important conclusion about the origin and cause of structural fires.

Age estimation of unaccompanied minors. Part II. Dental aspects

Recent years have brought a worldwide increase in cross-border migration due to a globalized economy and ongoing belligerent conflicts. As a result, the percentage of foreigners among the general population has steadily increased not only in Germany, but also in other countries. This trend has triggered a growing demand for forensic medicine to assess the age of adolescents and young adults. The individuals examined here are unaccompanied minors without valid identification documents who do not know their age or else are suspected of not giving their correct age. The mineralization of third molars is the main criterion for dental age estimation of living subjects in the relevant age group. To date insufficient knowledge has been obtained about how ethnic origin can influence tooth mineralization. This, however, constitutes a restraint on the reliability of age estimates and hence on the forensic value of information essential to legal security. A comparative study was conducted to present comparative data on third molar mineralization in a Caucasoid, Mongoloid and African sample. In conclusion, forensic age estimates of living subjects would be more powerful tools if population-specific standards were applied to evaluations of wisdom tooth mineralization. Since the mineralization of third molars is usually completed by the age of 19 or 20 years, this feature cannot be used to ascertain whether a person has attained the forensically relevant age of 21 years. The question was whether determination based on an orthopantomogram of a combination of features relevant to dental age estimation of adults supplies forensically useful information for ascertaining whether a person has attained 21 years of age. The features considered include the DMFT index of all permanent teeth, the DMFT index of all permanent teeth excluding third molars and the DFT index of third molars projecting beyond the occlusal plane. It can be concluded that an evaluation of the variations of the DMFT index does not by itself yield sufficient data to determine with the accuracy required in criminal proceedings whether a person has attained 21 years of age. An additional X-ray examination of the medial clavicular epiphyseal cartilage is, therefore, strongly recommended when assessing whether a person is over 21.     

Forensic anthropology in the global investigation of humanitarian and human rights abuse: Perspective from the published record

Forensic anthropologists have played key roles in the historical development of forensic science applications to global humanitarian and human rights issues. These anthropological initiatives can be traced back to the Smithsonian seminar organized by T. D. Stewart in 1968 and published in 1970. Key developments include the 1984 delegation sent by the American Association for the Advancement of Science to Argentina and the formation of the Argentine Forensic Anthropology Team. Subsequent highlights include major anthropological involvement in support of investigations by international criminal tribunals, formation of forensic anthropology teams in different countries and activities of the International Commission of Missing Persons and the forensic unit of the International Committee of the Red Cross. Recent developments feature the formation of the Humanitarian and Human Rights Resource Center of the American Academy of Forensic Sciences and its support of worthwhile projects in many countries. The published record provides historical perspective on these developments.

Forensic laboratory backlog: The impact of inconclusive results of marijuana analysis and the implication on analytical routine

Forensic laboratories worldwide are struggling to keep up with the increasing number of cases submitted for analysis, regardless of the reasons, backlog of controlled substances cases is a reality in many countries. In this paper we analyse the number of petitioned examinations (from 2016 to 2020) and the data from 11,655 marijuana TLC results from the Forensic Laboratory in the Federal District Civil Police in Brazil. Data demonstrates that backlog increases inconclusive results, with storage and light playing a crucial role in the process. Additionally we explored the repercussions of delayed forensic results for controlled substances and propose an approach to overcome waiting time in this context.     

A Test of the Passalacqua Age at Death Estimation Method Using the Sacrum

A test of the accuracy of the Passalacqua (J Forensic Sci, 5, 2009, 255) sacrum method in a forensic context was performed on a sample of 153 individuals from the J.C.B. Grant Skeletal Collection. The Passalacqua (J Forensic Sci, 5, 2009, 255) method assesses seven traits of the sacrum using a 7‐digit coding system. An accuracy of 97.3% was achieved using the Passalacqua (J Forensic Sci, 5, 2009, 255) method to estimate adult skeletal age. On average each age estimate differed by 12.87 years from the known age. The method underestimated the age of individuals by an average of 4.3 years. An intra‐observer error of 6.6% suggests that the method can be performed with precision. Correlation and regression analysis found that the sacral traits used in the Passalacqua (J Forensic Sci, 5, 2009, 255) method did not have a strong relationship with age or an ability to strongly predict age. Overall, the method was not practical for use in a forensic context due to the broad age ranges, despite the high accuracy and low intra‐observer error.     

Collection of post mortem data: DVI protocols and quality assurance

In many countries forensic odontologists are members of the Disaster Victim Identification (DVI) team. As part of their post mortem (PM) tasks work on the incident site may include securing and preserving the dental material and evidence before transport to the mortuary. In the autopsy room the main aim is to register the PM dental status. Photographs and radiographs are essential documentations in addition to a conventional registration of the dental status. Abbreviations in the registration may be used if agreed with the ante mortem (AM) team. Dental age estimation may be an aid in the sorting process and especially in victims without previous dental treatment. Interpol has a form set as part of their DVI manual. Forensic odontologists working in pairs and checking each other will act as quality assurance (QA) as suggested by International Organization for Forensic Odonto-Stomatology (IOFOS). Direct entry into the computer program as part of the registration in the autopsy room may save time and manpower.     

Chapter 2: The Legal Position and Organizational Forms of Forensic Psychiatric Expert Examination

The practical task of forensic psychiatry, which is one of the subdivisions of psychiatry, is to give an expert evaluation, on assignment from investigatory agencies and courts, and to devise and recommend measures for the prevention of socially dangerous acts by the mentally ill. Forensic psychiatric expert examination, like forensic medical, criminal, or any other type of expert examination, aids agencies of justice in establishing the facts in a case. Forensic psychiatric expert examination is called upon to assist the investigator and the court in determining whether an individual is a criminal or a legally irresponsible, mentally ill person; whether a person sentenced to a prison term should, because of mental illness, be released before his time is served; whether the investigator and the court may pursue the interrogation of a witness or victim with mental disorders, and whether the testimony of such persons may be used as court evidence. Such an expert examination is necessary in a civil suit in deciding the question of an individual's competence.     

Sidney Kaye, Ph.D. Internationally renowned forensic toxicologist

The importance of Dr. Sidney Kaye's contributions in the field of forensic science cannot be over-emphasized. He can be called a pioneer in the field of forensic science and forensic toxicology because of the many contributions he has made to analysis, the literature and poison control, as well as activities in alcohol and drug analysis. He has been fortunate in being a part of history through his relationship, as a student, to Dr. Alexander Gettler, the founder of modern-day forensic toxicology, and by working with Dr. Gradwohl in Saint Louis, Missouri in the 1950s, when the American forensic sciences were being organized. Dr. Kaye is one of the founders of the American Academy of Forensic Sciences, the foremost and largest forensic science organization in the World. It is for these reasons that he received the Alexander O. Gettler Award by the Toxicology Section of the American Academy of Forensic Sciences, for outstanding analytical achievements in forensic toxicology, at the annual meeting of the American Academy of Forensic Sciences, in Las Vegas, Nevada, on February 14, 1985.

Characteristics of Forensic Imaging Performance—An Analysis of Forensic Imaging Bottlenecks

Disk imaging involves copying all of the data from a source disk drive to a target. Typically, the target for the copy is another disk drive. Forensic processes developed years ago do not appear to be adequate for current storage technology. For example, with disk drive capacities now exceeding 1 Terabyte, a typical disk imaging can take over 8 hours at typical rates. With disk drive capacities increasing, forensic copying is expected to take even longer. Along with increase in disk capacity, the industry has also seen an increase in data transfer rates. In many cases, forensic imaging is taking longer than necessary. To identify the bottlenecks, an examination of different methods used to transfer data from a source disk was performed. Factors considered were differing disk access technologies. One finding is that the USB disk access technology (version 2.0 and earlier) is a significant bottleneck for data transfer rates, especially when the USB device is a write‐blocker. Other factors that contribute to the efficiency of a forensic copy are the file system used to write a forensic image and the data transfer size used when reading from a disk drive. Optimal parameters for performing a forensic acquisition from a disk drive are identified.

Forensic entomology: application, education and research in Western Australia.

Forensic entomology as a science and a tool for investigation has had slow beginnings in Australia. A number of small animal decomposition trials have been recorded in the literature but mostly from an ecological rather than a forensic entomology perspective. In the last 20 years, a number of more forensically orientated field trials on small pigs and some fly developmental trials in the laboratory have been conducted but lack any replication. The following article was presented at an international seminar to detail the current research in forensic entomology, the applications of forensic entomology in scene of crime (SOC) and homicide investigations and the education of police and judiciary in the discipline of forensic entomology in Western Australia over the last 10 years.     

法证科学领域的决策

随着法证DNA证据以及它所适用的概率模型日益凸显,反映了传统法证科学的局限性,并使人们对法证科学领域的决策产生了越来越多的质疑,焦点集中在对结论的解读方式和实际运用。分析表明,科学证据的本质不是绝对性或确定性的,而是概率性的;同时,事实审判者需要基于这些概率性的证据对事实作出明确的决定。因此,对于法证科学领域的决策,应当是专家在一系列归纳得出的特定假设基础上,就研究结果的概率进行恰当的报告,由事实审判者承担对概率作出决断的任务。
