Radiocarbon dating of ivory: Potentialities and limitations in forensics.

Forensic Sci Int 2019 Mar 30;299:114-118. Epub 2019 Mar 30.

CEDAD (CEntre for applied physics, DAting and Diagnostic) Department of Mathematics and Physics "Ennio de Giorgi", University of Salento, Italy.

The determination of the age of elephant ivory is a crucial aspect in the fight against illegal ivory trade which is still a relevant problem having triggered the decline of elephant populations due to poaching in different areas of the globe. Indeed, the absolute dating of the ivory allows, in forensics practice, to establish whether a determined sample or object was obtained and imported illegally, violating the international trade ban. In this frame the use radiocarbon dating has surely a great potential and is widely used. Read More

Genetic genealogy for cold case and active investigations.

Forensic Sci Int 2019 Mar 27;299:103-113. Epub 2019 Mar 27.

Parabon NanoLabs, Inc., 11260 Roger Bacon Dr. Suite 406, Reston, VA, 20190, USA.

Investigative genetic genealogy has rapidly emerged as a highly effective tool for using DNA to determine the identity of unknown individuals (unidentified remains or perpetrators), generating identifications in dozens of law enforcement cases, both cold and active. The amount of press coverage of these cases may have given the impression that the analysis is straightforward and the outcome guaranteed once a sample is uploaded to a database. However, the database query results serve only as clues from which in-depth genealogy and descendancy research must proceed to determine the possible identities of an unknown individual. Read More

The efficacy of DNA mixture to mixture matching.

Forensic Sci Int Genet 2019 Mar 30;41:64-71. Epub 2019 Mar 30.

Institute of Environmental Science and Research Limited, Private Bag 92021, Auckland, 1142, New Zealand.

Standard practice in forensic science is to compare a person of interest's (POI) reference DNA profile with an evidence DNA profile and calculate a likelihood ratio that considers propositions including and excluding the POI as a DNA donor. A method has recently been published that provides the ability to compare two evidence profiles (of any number of contributors and of any level of resolution) comparing propositions that consider the profiles either have a common contributor, or do not have any common contributors. Using this method, forensic analysts can provide intelligence to law enforcement by linking crime scenes when no suspects may be available. Read More

Using tibial fragments to reconstruct the total skeletal height of black South Africans.

Forensic Sci Int 2019 Mar 29. Epub 2019 Mar 29.

Human Variation and Identification Research Unit (HVIRU), School of Anatomical Sciences, Faculty of Health Sciences, University of the Witwatersrand, 7 York Road, Parktown, Johannesburg 2193, South Africa. Electronic address:

Stature is an important component of the biological profile of unknown skeletal remains and regression equations for estimating stature have been derived for a number of bones. However, bones are rarely recovered intact in both forensic and archaeological cases, and regression formulae for fragmentary remains have therefore been developed. These equations are, however, both sex- and population-specific, and while formulae exist for many populations, those using fragmentary tibiae do not exist for black South Africans. Read More

Discrimination of haplotype in mitochondrial DNA mixtures using LNA-mediated PCR clamping.

Forensic Sci Int Genet 2019 Mar 30;41:58-63. Epub 2019 Mar 30.

Department of Legal Medicine, Asahikawa Medical University, Asahikawa 078-8510, Japan.

Locked nucleic acid (LNA) has been widely used for various genetic analyses, and has many benefits, in terms of the specificity or sensitivity of amplification, because LNA-containing primers/probes form more stable duplexes with template DNA than probes lacking LNA. Here, we developed a new method for discriminating HV1 haplotypes from mitochondrial DNA (mtDNA) mixtures by applying PCR clamping using LNA. PCR clamping is based on the selective inhibition of amplification using LNA-containing probes, which can discriminate single-nucleotide differences. Read More

Determining the region of origin of blood spatter patterns considering fluid dynamics and statistical uncertainties.

Forensic Sci Int 2019 Feb 15;298:323-331. Epub 2019 Feb 15.

Department of Statistics, Iowa State University, 50010 Ames, IA, USA; Department of Computer Science, Iowa State University, 50010 Ames, IA, USA.

Trajectory reconstruction in bloodstain pattern analysis is currently performed by assuming that blood drop trajectories are straight along directions inferred from stain inspection. Recently, several attempts have been made at reconstructing ballistic trajectories backwards, considering the effects of gravity and drag forces. Here, we propose a method to reconstruct the region of origin of impact blood spatter patterns that considers fluid dynamics and statistical uncertainties. Read More

Forensic Sci Int Genet 2019 Apr 1;41:50-57. Epub 2019 Apr 1.

College of Policing, Coventry, United Kingdom. Electronic address:

The automatic exchange and comparison of DNA data between national databases to combat terrorism and cross-border crime in the EU area has been facilitated by the 2008 Prüm Decisions. While it was anticipated that all EU Member States would have fulfilled the requirements by August 2011, this has not yet occurred. Once each Member State has implemented the Prüm Decisions, which is expected to occur by spring or summer 2019, the EU Commission is planning on submitting a legislative proposal to amend the Prüm Decisions, possibly broadening its scope both in terms of types of data exchanged and the number of countries involved.

DNA testing in sexual assault cases: When do the benefits outweigh the costs?

Forensic Sci Int 2019 Mar 23;299:44-48. Epub 2019 Mar 23.

Sam Houston State University, United States.

Objectives: We examined 1200 sexual assault cold cases from Denver, Colorado to ascertain the rate of successful prosecution in which there was a DNA suspect match and the cost per conviction.

Results: Nearly 40% of the cases in which there was a DNA match failed to result in an arrest or prosecution primarily because victims were uncooperative or their testimony was judged to be unreliable. Other factors affecting conviction included crime context, victim availability, and the ability of the defendant to mount a consensual sex defense. Read More

Identification of closely related new psychoactive substances (NPS) using solid deposition gas-chromatography infra-red detection (GC-IRD) spectroscopy.

Forensic Sci Int 2019 Mar 23;299:21-33. Epub 2019 Mar 23.

Illicit Drugs Laboratory, Applied Sciences Group, Health Sciences Authority, 11, Outram Road, 169078, Singapore.

The challenges associated with the identification of new NPS have become more apparent with the increasing number of new drugs in the market and the need to identify the specific isomer due to legislation concomitant with the lack of reference standards for comparison. A recent new tandem technique, solid deposition gas chromatography-infra red detection spectroscopy (GC-IRD), which incorporates the GC for the separation of the different components in the sample matrix and infrared red (IR) spectroscopy which provides unique IR spectra of each component, has provided the necessary discrimination for the identification of isomers. This paper presents the identification and the application of an algorithm-based criteria (ABC) for the evaluation of the quality match factor (QMF) as an objective critical criteria in determining the correctness of an identification of close analogues in four classes of compounds; namely the JWH-018 and its structural isomers, AM-2201 and its fluoro positional isomers in the pentyl group, methylmethcathinone (MMC) and its methyl positional isomers in the phenyl ring, and dibutylone and its close analogues.

A multidisciplinary approach in overkill: Analysis of 13 cases and review of the literature.

Forensic Sci Int 2019 Mar 22;298:402-407. Epub 2019 Mar 22.

Department of Interdisciplinary Medicine, Section of Forensic Psychiatry, Policlinico di Bari Hospital, University of Bari, Italy.

The term overkill usually indicates the infliction of massive injuries by far exceeding the extent necessary to kill the victim. Only few articles or textbooks report this term that is mostly associated with sex-motivated homicides where injuries, generally stabbing, are directed to significant sexual parts of the body. The aim of this study is to shed light on the phenomenon of overkill by reviewing some cases personally analyzed by the authors from both a forensic pathology rather than forensic psychiatry views.

We investigate the ability of the 31 SNP loci in the Global AIMs Nano set to distinguish self-declared Australian Aboriginal individuals from European, Oceanic, African, Native American and East Asian populations. Human evolution suggests that Australian Aboriginal individuals came to Australia approximately 50 000 years ago, during the time it made up part of Sahul. Since then the colonisation of Australia by Europeans has meant significant admixture within the Australian Aboriginal population. Read More

Polymorphisms and microvariant sequences in the Japanese population for 25 Y-STR markers and their relationships to Y-chromosome haplogroups.

Forensic Sci Int Genet 2019 Mar 17. Epub 2019 Mar 17.

National Research Institute of Police Science, 6-3-1, Kashiwanoha, Kashiwa, Chiba 277-0882, Japan.

Y-chromosomal short tandem repeat (Y-STR) markers have been used for forensic purposes such as kinship analysis of male-linage and detection of a male DNA component in a mixture of male and female DNA. Recently, rapidly mutating Y-STR (RM Y-STR) markers were reported that are expected to help distinguish close male relatives. This study provides data of Y-chromosomal haplotypes for 25 Y-STR markers, including six RM Y-STR markers (DYS576, DYS627, DYS518, DYS570, DYS449 and DYF387S1) typed with the Yfiler™ Plus kit in 1299 males of the Japanese population.

DNA mixture interpretation can produce opposing conclusions by qualified forensic analysts, even within the same laboratory. The long-delayed publication of the National Institutes of Standards and Technology (NIST) study of 109 North American crime laboratories in this journal demonstrates this most clearly. This latest study supports earlier work that shows common methods such as the Combined Probability of Inclusion (CPI) have wrongly included innocent people as contributors to DNA mixtures. Read More

Probabilistic genotyping approaches are increasingly used for the interpretation of DNA mixtures. To explore the specificity of one of these systems (STRmix), we conducted an extensive study using 24 complex mixtures: all were known or apparent 4-person mixtures with at least one contributor representing less than 20% of total DNA, and all mixtures had at least one contributor with suboptimal DNA quantity. Those mixtures were either generated in-house or from casework. Read More

Comparison of protein expression levels and proteomically-inferred genotypes using human hair from different body sites.

Forensic Sci Int Genet 2019 Mar 11;41:19-23. Epub 2019 Mar 11.

Forensic Science Graduate Program and Department of Environmental Toxicology, University of California, Davis, CA, USA. Electronic address:

The microanatomy of human hair differs as a function of the site of origin on the body. This was a major consideration when anatomical features of hair were used as a means of comparison and human identification. Recent advances have demonstrated that proteomics of the hair shaft can be used to develop profiles of protein abundance and genetically variant peptides, the latter in turn being used to infer genotypes of SNP alleles.

Applications and challenges of forensic proteomics.

Forensic Sci Int 2019 Apr 22;297:350-363. Epub 2019 Jan 22.

Statistical Modeling and Experimental Design Group, Pacific Northwest National Laboratory, Richland, Washington, USA.

Mass spectrometry-based proteomics has been a useful tool for addressing numerous questions in basic biology research for many years. This success, combined with the maturity of mass spectrometric instrumentation, the ever-increasing availability of protein sequence databases derived from genome sequencing, and the growing sophistication of data analysis methods, places proteomics in a position to have an important role in biological forensics. Because proteins contain information about genotype (sequence) and phenotype (expression levels), proteomics methods can both identify biological samples and characterize the conditions that produced them.

Latent fingermark detection using functionalised silicon oxide nanoparticles: Method optimisation and evaluation.

Forensic Sci Int 2019 Mar 14;298:372-383. Epub 2019 Mar 14.

University of Technology Sydney, Centre for Forensic Science, Broadway, NSW, 2007, Australia.

The application of nanoparticles for latent fingermark detection has been reported in the literature over the past two decades. One of the nanoparticles that shows promise to become a routine technique is functionalised silicon oxide nanoparticles (SiO NPs). In a recent optimisation of the technique, the use of carboxyl-functionalised SiO NPs doped with luminescent ruthenium complex was proposed as a breakthrough for latent fingermark detection.

Methods for analysis of glass in glass-containing gunshot residue (gGSR) particles.

Forensic Sci Int 2019 Mar 16;298:359-371. Epub 2019 Mar 16.

Flinders University, Sturt Road, Bedford Park, South Australia 5042, Australia. Electronic address:

When lead, barium and antimony, or lead, barium, calcium, silicon and tin are found together in particles associated with a shooting investigation they are considered characteristic of gunshot residue (GSR). Antimony and tin are often absent from the primer of many low calibre rimfire ammunitions, which are the type most commonly used in Australia. Therefore, the likelihood of characteristic particles forming during the firing process of such rimfire ammunition is significantly less than the likelihood of these particles arising from higher calibre ammunition.

In forensic anthropology, the estimation of age at death is mainly required to establish a biological profile and facilitate individual identification. The Suchey-Brooks (SB) system represents one of the most commonly used and tested methods of assessment based on the morphological characteristics of the pubic symphysis. However, this method has certain drawbacks, including frequently inaccurate estimation for older individuals. Read More

Applicability of Demirjian's method for age estimation in a sample of Italian children with Down syndrome: A case-control retrospective study.

Forensic Sci Int 2019 Mar 15;298:336-340. Epub 2019 Mar 15.

Department of Biomedical and Neuromotor Sciences (DiBiNeM), Unit of Dental Care for Special Needs Patients and Pediatric Dentistry, University of Bologna, Bologna, Italy.

Age estimation is widely applied in several clinical and forensic fields. The radiographic evaluation of dental development is one of the most accepted tools for this purpose. Among the different methods proposed, Demirjian's method was the most extensively used and tested in the medical literature revealing that the original standards for the French-Canadian population tends to over-estimate the age of different population groups.

Forensic Sci Int Genet 2019 Mar 25;41:11-18. Epub 2019 Mar 25.

Institute of Forensic Medicine, West China School of Basic Sciences and Forensic Medicine, Sichuan University, Chengdu, China. Electronic address:

The Hui group is the second largest ethnic minority and one of the most widespread ethnic groups in China. However, the genetic architecture of the Hui population remains largely unexplored, particularly with respect to the male-specific region of the Y chromosome. Here, we studied nine Hui populations (Xinjiang, Qinghai, Gansu, Ningxia, Shaanxi, Henan, Shandong, Sichuan, Yunnan) using 157 Y-chromosome single nucleotide polymorphisms (Y-SNPs) and 27 short tandem repeats (Y-STRs) to unravel their genetic substructure and forensic characteristics.

The quality of developmental reference data in forensic entomology: Detrimental effects of multiple, in vivo measurements in Creophilus maxillosus L. (Coleoptera: Staphylinidae).

Forensic Sci Int 2019 Mar 9;298:316-322. Epub 2019 Mar 9.

Laboratory of Criminalistics, Adam Mickiewicz University, Św. Marcin 90, 61-809 Poznań, Poland; Centre for Advanced Technologies, Adam Mickiewicz University, Umultowska 89C, 61-614 Poznań, Poland.

Although in vivo measurements of larval insects are often performed during developmental studies of necrophilous beetles, their impact on development has not been studied. During measurements insects are taken out of the incubator for a few minutes at room temperature, which may affect the development and eventually the quality of the developmental reference data. Additionally, while being measured larvae are under stress which may have an effect on their development. Read More
