Forensic Sci Int 2019 Feb 1;297:27-34. Epub 2019 Feb 1.

WMG, International Manufacturing Centre, University of Warwick Coventry, CV4 7AL, UK.

Forensic imaging technology has rapidly advanced over the past several decades and is gaining increasing significance in medico-legal death investigations. Medical-grade computed tomography (CT) is now routinely used in post-mortem examinations at numerous institutions across the globe. However, the resolution of medical-grade CT is limited and unsuitable when used to depict some smaller anatomical structures or micro-trauma. Read More

Department of Veterinary Medicine, Università degli Studi di Milano, Italy. Electronic address:

Age estimation in growing dogs is crucial not only in clinical practice but increasingly so in forensic practice as well. In the last few years, it has assumed great importance for correctly identifying the age of puppies illegally imported to Italy as well as to other European countries. Puppies are, in fact, transported when they are too young to be moved, which can cause both animal/public health and animal welfare issues. Read More

Rapid visual detection of nitroaromatic explosives using a luminescent europium-organic framework material.

Forensic Sci Int 2019 Jan 29;297:1-7. Epub 2019 Jan 29.

Department of Forensic Chemistry, Criminal Investigation Police University of China, Shenyang 110035, China. Electronic address:

Rapid field screening is enormously important in forensic analysis of explosives. In this article, we used a methodology based on a strong red-fluorescent europium-organic framework (Eu-MOF) material for sensitive and selective detection of picric acid, TNT, and tetryl using the fluorescence quenching effect. Results indicate that Eu-MOF can be used for the visual detection of these three explosives with low detection limits (20-140 μg/mL) and high quenching efficiency (Ksv > 10 M). Read More

Automation and developmental validation of the ForenSeq DNA Signature Preparation kit for high-throughput analysis in forensic laboratories.

Forensic Sci Int Genet 2019 Jan 31;40:37-45. Epub 2019 Jan 31.

Institut National de Police Scientifique, Laboratoire de Police Scientifique de Lyon, 31 Avenue Franklin Roosevelt, 69134, Ecully Cedex, France. Electronic address:

Massively parallel sequencing (MPS) applications in forensic science highlight the advantages of this technique compared to capillary electrophoresis (CE). The multiplexing of a wide range of genetic markers and access to the full amplicon sequence, allowing the detection of isoalleles, make it a very promising tool which could be applied to the most challenging casework DNA samples. However, the complexity of the manual library preparation protocol, potential DNA contamination and sample tracking issues are the main reasons why forensic scientists still hesitate to implement MPS analytical workflows in their laboratory.

Institute of Forensic Medicine, University Hospital of Schleswig-Holstein, Arnold-Heller-Strasse 12, 24105 Kiel, Germany. Electronic address:

Since DNA from touched items and surfaces ("touch DNA") can successfully and reliably be analyzed, the question as to how a particular DNA containing sample came to be from where it was recovered is of increasing forensic interest and expert witnesses in court are increasingly challenged to assess for instance whether an incriminatory DNA sample matching to a suspect could have been transferred to the crime scene in an innocent manner and to guess at the probability of such an occurrence. The latter however will frequently entail expressing a subjective probability i.e. Read More

Forensic Advisors, at the Belgian National Institute for Criminalistics and Criminology, occupy a centralising role in regards to analytical information and forensic questions in the judicial cases. Magistrates can request their advice but remain formally responsible for all decisions regarding trace processing. Nevertheless, magistrates' decisions are guided by the fact that a trace is recommended for analysis by a Forensic Advisor in all three types of cases studied (homicide, robbery, burglary).

Forensic Sci Int 2019 Jan 21;296:91-100. Epub 2019 Jan 21.

Institute of Chemistry, University of Brasília, Distrito Federal, Brazil. Electronic address:

Determining the chronological order of crossed lines is a recurrent problem in forensic analysis of documents. One of the most important requirement of these analyses is the use of non-destructive techniques to maintain the integrity of the documents for further analysis as judicial evidences. Thus, this work proposes an objective, non-destructive, easy-to-execute analysis protocol for forensic analysis, using the hyperspectral mode of the VSC6000®, which is an equipment found in most laboratories of questioned documents.

Forensic gait analysis - Morphometric assessment from surveillance footage.

Forensic Sci Int 2019 Jan 19;296:57-66. Epub 2019 Jan 19.

Centre for Forensic Science, University of Technology Sydney, 15 Broadway, Ultimo, New South Wales, 2007, Australia.

Following the technological rise of surveillance cameras and their subsequent proliferation in public places, the use of information gathered by such means for investigative and evaluative purposes sparked a large interest in the forensic community and within policing scenarios. In particular, it is suggested that analysis of the body, especially the assessment of gait characteristics, can provide useful information to aid the investigation. This paper discusses the influences upon gait to mitigate some of the limitations of surveillance footage, including those due to the varying anatomical differences between individuals. Read More

Mitigating the effects of reference sequence bias in single-multiplex massively parallel sequencing of the mitochondrial DNA control region.

Forensic Sci Int Genet 2019 Jan 16;40:9-17. Epub 2019 Jan 16.

Department of Genetics & Genome Biology, University of Leicester, University Road, Leicester LE1 7RH UK. Electronic address:

Sequence analysis of the mitochondrial DNA (mtDNA) control region can provide forensically useful information, particularly in challenging samples where autosomal DNA profiling fails. Sub-division of the 1122-bp region into shorter PCR fragments improves data recovery, and such fragments can be analysed together via massively parallel sequencing (MPS). Here, we generate mtDNA data using the prototype PowerSeq™ Auto/Mito/Y System (Promega) MPS assay, in which a single PCR reaction amplifies ten overlapping amplicons of the control region, in a set of 101 highly diverse samples representing most major clades of the mtDNA phylogeny.

School of Forensic Science, People's Public Security University of China, No. 1 Muxidi Nanli, Xicheng District, Beijing 100038, China.

In the investigation of criminal cases involving metallic weapons such as firearms and knives, the trace metal detection test (TMDT) and the transfer detection technique are two effective and on-the-spot methods to link a suspect and a suspected metallic weapon. In general, these tests need to be conducted on suspects' hands or done by lifting trace metals from their hands within 3 days of the crime being committed. However, if no suspects are arrested within this period, neither of these two techniques is applicable. Read More

Application of differential scanning calorimetry in the analysis of apprehended formulations of anabolic androgenic steroids.

Forensic Sci Int 2019 Jan 10;296:15-21. Epub 2019 Jan 10.

Center of Chemical, Pharmaceutical and Food Sciences, Laboratory of Lipidomics and Bioorganic, Federal University of Pelotas, Campus Universitário Capão do Leão s/n, 96900-010, Brazil. Electronic address:

Over the past ten years, there has been a significant increase in the amount of formulations containing anabolic androgenic steroids apprehended worldwide. A considerable amount of these illicit preparations is falsified imposing a series of challenges for the analytical identification of alleged active ingredients due to the presence of interferers. In this sense, the aim of this work was to identify and quantify the active ingredient using cholesterol as internal standard in eight apprehended formulations of anabolic androgenic steroids in either tablet, capsule or injectable forms employing visual inspection and instrumental analysis of Fourier Transform Infrared Spectroscopy, Gas Chromatography - Mass Spectrometry and Differential Scanning Calorimetry.

The potential use of Piwi-interacting RNA biomarkers in forensic body fluid identification: A proof-of-principle study.

Forensic Sci Int Genet 2019 Mar 8;39:129-135. Epub 2019 Jan 8.

Institute of Forensic Medicine, West China School of Basic Medical Sciences & Forensic Medicine, Sichuan University, Chengdu, 610041, China. Electronic address:

In the forensic community, RNA profiling has been investigated as a potential method to identify body fluids. Several RNA molecules, including messenger RNA (mRNA), microRNA (miRNA) and circular RNA (circRNA), have been explored as biomarkers to distinguish different body fluids and have led to considerable interest in the development of RNA biomarkers for forensic purposes. Piwi-interacting RNA (piRNA), a class of noncoding RNAs, is a potential biomarker for body fluid identification because of its short length (˜24-32 nt) and specific expression pattern in human tissues.

A comparative study for the isolation of exogenous trace DNA from fingernails.

Forensic Sci Int Genet 2019 Mar 4;39:119-128. Epub 2019 Jan 4.

State of California, Department of Justice, Bureau of Forensic Services, 1001 West Cutting Boulevard, Richmond, CA 94804, United States.

Often fingernails from a victim or suspect involved in a physical assault, such as murder or sexual assault, are submitted to crime laboratories for DNA testing of foreign/exogenous biological material; however, very few studies have been conducted comparing the effectiveness of different sampling methods on the removal of foreign/exogenous DNA while minimizing the fingernail endogenous DNA. In this study three different sampling methods (swabbing, PBS soak, and PrepFiler® lysis buffer soak) were compared in order to identify one that minimizes the amount of endogenous DNA removed and maximizes the amount of foreign/exogenous male DNA removed. The samples were processed using the Tecan HIDEVO150 robot in order to reduce analyst time and the DNA mixtures were interpreted using the probabilistic genotyping software STRmix™. Read More

True colors: A literature review on the spatial distribution of eye and hair pigmentation.

Forensic Sci Int Genet 2019 Mar 2;39:109-118. Epub 2019 Jan 2.

Cologne Center for Genomics, University of Cologne, Cologne, Germany. Electronic address:

DNA-based prediction of externally visible characteristics has become an established approach in forensic genetics, with the aim of tracing individuals who are potentially unknown to the investigating authorities but without using this prediction as evidence in court. While a number of prediction models have been proposed, use of prior probabilities in those models has largely been absent. Here, we aim at compiling information on the spatial distribution of eye and hair coloration in order to use this as prior knowledge to improve prediction accuracy. Read More

School of Forensic Sciences, Center for Health Sciences, Oklahoma State University, Tulsa, OK, United States. Electronic address:

The value of RNA analysis in the forensic laboratory as one means of identifying the nature of biological evidence of forensic relevance has been well established. The degradation of RNA in dried body fluid stains has also been an area of forensic interest because of the potential to estimate the age of a stain recovered from a crime scene. Here we describe a qPCR assay that demonstrates it is possible to estimate the age of bloodstains with reasonable accuracy. Read More

A preliminary investigation of lung availability of cannabinoids by smoking marijuana or dabbing BHO and decarboxylation rate of THC- and CBD-acids.

Forensic Sci Int 2019 Feb 6;295:207-212. Epub 2019 Jan 6.

Landeskriminalamt Nordrhein-Westfalen, KTI - Teildezernat 51.2 Betäubungsmittel, Völklinger Strasse 49, 40221, Düsseldorf, Germany.

Highly potent cannabis concentrates obtained by butane or by supercritical carbon dioxide-extraction are gaining popularity. These extracts called butane hash oil (BHO) with Δ-tetrahydrocannabinolic acid A (THCA) contents above 60% are consumed by flash vaporization on a glowing titanium nail, followed by inhalation of the resulting vapor through a water pipe in a single puff - a technique referred to as "dabbing". We herein investigated the decarboxylation rate of THCA during artificial smoking of cannabis plant material and simulated dabbing, and the lung availability of Δ-tetrahydrocannabinol (THC) which we define as the recovery of THC in the smoke and vapor condensates.

Surface coatings including fingerprint residues can significantly alter the size and shape of bloodstains.

Forensic Sci Int 2019 Feb 19;295:189-198. Epub 2018 Dec 19.

Department of Mechanical Engineering, Boston University, Boston, MA 02215, USA. Electronic address:

When conducting a blood pattern analysis (BPA) the size, shape, distribution, and location of bloodstains found at a crime scene may be critical in forming a hypothesis as to what transpired during a bloody event. Prior studies have demonstrated that the size and shape of a bloodstain on a smooth surface are determined from impact dynamics and to a lesser degree by the target material itself. Yet, these studies have relied on clean surfaces, and it is unclear whether the presence of microscopic coatings and residues could significantly alter the size or shape of the dried stain.

Analysis of 21 autosomal STRs in Saudi Arabia reveals population structure and the influence of consanguinity.

Forensic Sci Int Genet 2019 Mar 21;39:97-102. Epub 2018 Dec 21.

Department of Genetics & Genome Biology, University of Leicester, University Road, Leicester, United Kingdom. Electronic address:

Variation in the 21 autosomal STRs detected by the GlobalFiler multiplex was investigated in a sample of 523 indigenous male Arabs from five geographic regions of Saudi Arabia. Although allele frequencies for the entire dataset were found to be broadly similar to those determined in previous studies of Saudi citizens, significant differences were found among regions. Heterozygote deficiency was observed at nearly all loci in all regions, probably as a consequence of high levels of consanguineous marriage; in the case of D2S1338, which showed the largest deviation from Hardy-Weinberg equilibrium, the presence of a null allele also played a part.
