Crime scene investigators, law enforcement agencies, and prosecuting attorneys have recommended that this form of testing may successfully advance the investigation and prosecution of cases with limited biological evidences, such as bones, hairs and degraded skeletal remains. Defense attorneys are also increasingly requesting testing of samples with advancement of methods that may aid in exonerating their clients. MtDNA an extra nuclear genome, has certain features that make it desirable for forensics; namely, high copy number, lack of recombination, matrilineal inheritance, heteroplasmy, expression variability, and mitotic segregation. MtDNA typing has become routine in forensic biology since mid of 1980 and is a last resort for testing highly degraded biological debris. Further, the high mutation rate of the human mitochondrial

The fact that different people host radically different microbiota highlights forensic perspectives in understanding what leads to this variation and what regulates it, in order to effectively use microbes as forensic evidence. This narrative review provides an overview of some of the main scientific works so far produced, focusing on the potentiality of using skin microbiome profiling for human identification in forensics. This review was performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The examined literature clearly ascertains that skin microbial communities, although personalized, vary systematically across body sites and time, with intrapersonal differences over time smaller than interpersonal ones, showing such a high degree of spatial and temporal variability that the degree and nature of this variability can constitute in itself an important parameter useful in distinguishing individuals from one another.

    Human remains and identification HUMAN REMAINS AND VIOLENCE Human remains and identification Human remains Human remains and identification presents a pioneering investigation into the practices and methodologies used in the search for and and identification exhumation of dead bodies resulting from mass violence. Previously absent from forensic debate, social scientists and historians here Mass violence, genocide, confront historical and contemporary exhumations with the application of social context to create an innovative and interdisciplinary dialogue. and the ‘forensic turn’ Never before has a single volume examined the context of motivations and interests behind these pursuits, each chapter enlightening the Edited by ÉLISABETH ANSTETT political, social, and legal aspects of mass crime and its aftermaths. and JEAN-MARC DREYFUS The book argues that the emergence of new technologies to facilitate the identification of dead bodies has led to a ‘forensic turn’, normalizing exhumations as a method of dealing with human remains en masse. However, are these exhumations always made for legitimate reasons? And what can we learn about societies from the way in which they deal with this consequence of mass violence? Multidisciplinary in scope, this book presents a ground-breaking selection of international case studies, including the identification of corpses by the International Criminal Tribunal for the Former Yugoslavia, the resurfacing ANSTETTand of human remains from the Gulag and the sites of Jewish massacres from the Holocaust.

Carmichael,3 established new guidelines and procedures for determining the evidentiary reliability of expert testimony. Following the Daubert trilogy, the admissibility of expert testimony is presumably based not only on an analysis of the evidence's legal merits and Frye's general acceptance standard,4 but also on the judicial analysis of the qualifications of the expert, the methods by which the expert arrives at his or her 5 conclusions, and even the conclusions themselves.

  • Forensic Methods of Identifying Corpses with Unknown Identity
    Forensic Methods of Identifying Corpses with Unknown Identity Ovidiu Andrei Hamburda Faculty of “Economic Sciences and Public Administration," Law Specialization, University “Ștefan cel Mare,” Romania Master in Criminal Sciences at "Dimitrie Cantemir" Christian University of Bucharest, [email protected] ABSTRACT: Finding the truth is the most difficult process, especially in a society that reveals itself as a high- speed field, whose passengers combine good and evil, honor and dishonesty, respect for the law and crime. Identification of dead bodies is one of the most common but complicated activities that the magistrate, criminal investigation dead bodies, criminalist or forensic doctor encounters, because compared to the living people who appreciate both the static signs, the dynamic signs and the functional features noted by different gestures, attitudes, etc. only the static forms and the personal objects on them or the clothing are appreciated in the case of dead bodies. Most procedures claim certain data and information to be compared, such as DNA, fingerprints, dentition, etc., but if they do not exist, comparison with the rest of the population is impossible. To identify a person, the forensic research bodies also found other methods, such as the over-projection method, the reconstruction of the skull physiognomy, the skeletal identification, dental or dental identification. KEYWORDS: clothes, dead bodies, dentition, DNA, research, skeleton, unknown Introduction In the society where we living, personal and national security is very easy to attack, hence the need for more stringent and trustworthy measures to identify and secure our identity. Although in the book of Alexander Dumas - Martin Guerre, identity was established by cunning and confession, in today's world, a simple comparison of DNA would solve the problem, beyond any reasonable uncertainty (Thompson and Black 2007).

Chesapeake Street, Norman, Oklahoma, OK 73019, USA Received 31 December 2004; received in revised form 2 May 2005; accepted 3 May 2005 Abstract Forensic identification of ‘wild’ versus hatchery-produced (cultured) red drum (Sciaenops ocellatus), an economically important marine fish in the southern United States, was assessed using hypervariable nuclear-encoded microsatellites and sequences of mitochondrial DNA. Both genotype exclusion and likelihood-ratio tests successfully identified ‘wild’ and ‘cultured’ individuals within requisite error bounds and within the context of complete parental sampling. Of the two, genotype exclusion was more effective, producing satisfactory results with fewer microsatellites and larger allowable error rates. Assignment tests proved ineffective, most likely because of the low level of genetic divergence between the sampled populations. An optimal, minimum set of ten markers that will reduce potential genotyping costs is identified. Results of the study should allay concerns regarding identification of ‘wild’-caught fish sold illegally. # 2005 Elsevier Ireland Ltd. All rights reserved.

  • Forensic Face Recognition: a Survey
    Forensic Face Recognition: A Survey Tauseef Ali, Raymond Veldhuis, Luuk Spreeuwers Signals and Systems Group, FEMCS, University of Twente, Enschede, The Netherlands Abstract Beside a few papers which focus on the forensic aspects of automatic face recognition, there is not much published about it in contrast to the literature on developing new techniques and methodologies for biometric face recognition. In this report, we review forensic facial identification which is the forensic experts‟ way of manual facial comparison. Then we review famous works in the domain of forensic face recognition. Some of these papers describe general trends in forensics [1], guidelines for manual forensic facial comparison and training of face examiners who will be required to verify the outcome of automatic forensic face recognition system [2]. Some proposes theoretical framework for application of face recognition technology in forensics [3] and automatic forensic facial comparison [4, 5]. Bayesian framework is discussed in detail and it is elaborated how it can be adapted to forensic face recognition. Several issues related with court admissibility and reliability of system are also discussed. Until now, there is no operational system available which automatically compare image of a suspect with mugshot database and provide result usable in court. The fact that biometric face recognition can in most cases be used for forensic purpose is true but the issues related to integration of technology with legal system of court still remain to be solved. There is a great need for research which is multi- disciplinary in nature and which will integrate the face recognition technology with existing legal systems.

Final Summary Overview Department of Justice, National Institute of Justice Grant Number: 2014-DN-BX-K021 Title: Body fluid analysis by surface enhanced Raman spectroscopy for forensic applications PI: Lawrence D. Ziegler, Professor of Chemistry, Boston University [email protected] Executive summary: Surface enhanced Raman spectroscopy, combined with statistical analyses, provides rapid (~minutes) detection and identification of trace amounts of blood, semen, vaginal fluid and saliva and their mixtures. Donor variability is less than the difference between body fluid signatures. The signatures are robust over time (> months) and the molecular components of the body fluid spectra are identified. Trace blood stains can be identified following luminol based location protocols and distinguished from household agents. Animal blood species can also be identified and blood detection sensitivities exceed existing standard methodologies. This nondestructive, portable platform uses minimal sample material amounts allowing for subsequent additional tests of suspected body fluid stains.
