In this course, offered by the Institute for Public Health Genetics and the Department of Biostatistics, we will be learning and discussing how advances in genetic profiling have affected forensic science. Although DNA profiling has had an enormous impact on forensic science over the past 25 years, by determining whether a person either matches or does not match biological evidence associated with a crime, the use of genetic information in parentage testing goes back much further. Those activities, along with the identification of remains and settling of immigration disputes, rest on the principles of genetics and statistics. There is parallel activity in wildlife forensics and plant variety protection. As genomic technology develops, the possibility of implicating or excluding a person, or their relatives, with a crime has increased. This increases the need for care in interpreting results and it raises issues of privacy. The course will develop students ability to perform calculations for ...
The projects main objective was to achieve a cost-effective genotyping of SNPs at high density in DNA samples with concentrations and fragmentation levels common in a forensic settings, and to do so at accuracies above and beyond those necessary for ERSA relationship detection. ERSA is a computational method that uses high-density SNP genotypes to link relatives at 6th-degree relationships with high confidence. This method has proven effective on pristine DNA. The main obstacle to the application of ERSA to forensic DNA is that it requires high-density, high-quality SNP genotype data, which cannot currently be generated from many forensic DNA samples. Such samples are often too fragmented, chemically damaged, inhibited, or limited in quantity. The current project identified and quantified the error patterns in the genotyped high-density SNP data from limited and fragmented DNA samples. Error patterns were compared with those observed from genotyping laboratory-grade, high-quality samples. A ...
Due to the Corona virus/Covid-19 situation we have decided to cancel this years ESWG scientific meeting in Oslo, Norway. This is sad of course, but we could not see how the meeting would be successful given the circumstances. We have chosen not to postpone the meeting but instead plan for a new scientific meeting in 2022. We will have an ESWG member meeting at the ISFG congress in Washington, 2021, where we will discuss and decide the host of the 2022 meeting. We are grateful for all the work that our colleagues in Oslo have done on the planning. We would also like to thank all planned workshop leaders, keynote speakers and participants that have registered, and hope that you will join our 2022 meeting! Furthermore, we aim for a webinar in the autumn to present and discuss the results from the ESWG proficiency testing program. More information will follow! (Andreas Tillmar ...

DNA analysis of ancient skeletal remains is invaluable in evolutionary biology for exploring the history of species, including humans. Contemporary human bones and teeth, however, are relevant in forensic DNA analyses that deal with the identification of perpetrators, missing persons, disaster victims or family relationships. They may also provide useful information towards unravelling controversies that surround famous historical individuals. Retrieving information about a deceased persons externally visible characteristics can be informative in both types of DNA analyses. Recently, we demonstrated that human eye and hair colour can be reliably predicted from DNA using the HIrisPlex system. Here we test the feasibility of the novel HIrisPlex system at establishing eye and hair colour of deceased individuals from skeletal remains of various post-mortem time ranges and storage conditions. Twenty-one teeth between 1 and approximately 800 years of age and 5 contemporary bones were subjected to DNA

Forensic samples are particularly prone to such damage due to their prolonged exposure after deposition at crime scenes or mass disasters. Current methods for typing such samples rely heavily on the intact DNA template, and can be adversely affected by damage that is present. Proposed solutions center around increased access to the smaller remaining fragments and/or increased sensitivity. However, all rely on the polymerase chain reaction to copy the starting material; the required polymerase can be impeded by certain types of damage such as dimer-formation after ultraviolet light ...

BACKGROUND: Persons whose identifying DNA profile (STR profile) is not yet known to the ingvestigating authorities cannot be identified by standard forensic DNA analysis (STR profiling) as it is now practiced. In view of the current public debate, particularly in Germany, on the legalization of so-called forensic DNA phenotyping, we present its scientific basis, societal aspects, and forensic applications and describe the analytic techniques that are now available. METHODS: This review is based on pertinent publications that were retrieved by a selective search in PubMed and in public media, and on the authors own research. RESULTS: Forensically validated DNA test systems are available for the categorization of eye, hair, and skin color and the inference of continental biogeographic ancestry. As for statistical measures of test accuracy, the AUC (area under the curve) values lie in the range 0.74-0.99 for eye color, 0.64-0.94 for hair color, and 0.72-0.99 for skin color, depending on the ...

DNA methylation is a stable epigenetic modification which displays significant promise in forensic applications. The aim of this research was to assess the performance of DNA methylation markers in two of these: the differentiation of identical twins and the chronological age estimation of a biological sample donor. Candidate CpG sites were identified from the literature for each application and analysed using targeted multiplex amplification of bisulfite converted DNA in combination with massive parallel sequencing. Thirty-one CpG sites from three amplicons were examined in buccal samples collected from five pairs of identical twins. The results of this study confirmed that identical twins can be differentiated at the Alu-Sp and IGF2-shore loci, with all twin pairs displaying significantly different methylation patterns at Alu-Sp. A total of 84 CpG markers from seven loci were investigated in 28 blood samples collected from males and females aged from 22-62 years for the age estimation study. ...

Up until recently, DNA forensics labratories would only use DNA samples larger than a few hundred picograms. A picogram is one trillionth of a gram. Smaller quantities of DNA are more difficult to test, especially with older DNA analysis methodologies.. Since 1999, the UK Forensic Science Service has used a DNA profiling technique called Low Copy Number, which can analyze DNA samples as small as 100 picograms.. The DNA laboratory in the office of New York Citys chief medical examiner has introduced two DNA profiling techniques designed to analyze even smaller DNA samples.. The labs Dr Theresa A Caragine, a forensic scientist, developed the high-sensitivity testing method, and implemented it in 2006. After several years of experience with that method, Caragine and Dr.Adele A Mitchell invented the Forensic Statistical Tool, which is specialized forensic DNA analysis software. Both methods are still being used to test really tiny DNA samples, as well as DNA samples which might contain genetic ...

Forensic samples that contain too little template DNA or are too degraded require alternate genetic marker analyses or approaches to what is currently used for routine casework. Single nucleotide polymorphisms (SNPs) offer promise to support forensic DNA analyses because of an abundance of potential markers, amenability to automation, and potential reduction in required fragment length to only 60-80 bp. The SNP markers will serve an important role in analyzing challenging forensic samples, such as those that are very degraded, for augmenting the power of kinship analyses and family reconstructions for missing persons and unidentified human remains, as well as for providing investigative lead value in some cases without a suspect (and no genetic profile match in CODIS). The SNPs for forensic analyses can be divided into four categories: identity-testing SNPs; lineage informative SNPs; ancestry informative SNPs; and phenotype informative SNPs. In addition to discussing the applications of these different

Y chromosomal short tandem repeats (Y-STRs) are widely used in forensic genetics. The current application is mainly to detect non-matches, and subsequently release wrongly accused suspects. For matches the situation is different. For now, most analysts will just say that the haplotypes matched but they will not assess the evidential value of this match. This is understandable given the fact that a consensus of estimating the evidential value has not yet been reached. However, work on getting there is in progress. In this talk, the aim is to review some of the current methods for assessing the evidential value of a Y-STR match. This includes proposal for a new way to compare methods estimating match probabilities and a discussion of correcting for population substructure through the so-called θ (theta) method.. ...

The second lawsuit was filed in the Central District of California, and involves another patent asserted in the AmpFLSTR litigation, Re37,984. According to the complaint, this patent was exclusively licensed by Max-Planck-Gesellschaft to a company called Research Genetics pursuant to a 1993 license agreement. In 1996, Research Genetics granted Promega exclusive and nonexclusive rights under the patent in certain fields. According to the complaint, Research Genetics retained rights under the patent in other fields, including uses in cell line authentication/identification. Research Genetics was subsequently acquired by Life Technologies, and Life Technologies alleges that under the 1996 agreement the company retains the right to use the patented technology in the AuthentiFiler products. Promega evidently disputes this interpretation of the import of the license agreement ...

This study analyzes data sharing regarding mitochondrial, Y chromosomal and autosomal polymorphisms in a total of 162 papers on ancient human DNA published between 1988 and 2013. The estimated sharing rate was not far from totality (97.6% ± 2.1%) and substantially higher than observed in other fields of genetic research (evolutionary, medical and forensic genetics). Both a questionnaire-based survey and the examination of Journals editorial policies suggest that this high sharing rate cannot be simply explained by the need to comply with stakeholders requests. Most data were made available through body text, but the use of primary databases increased in coincidence with the introduction of complete mitochondrial and next-generation sequencing methods. Our study highlights three important aspects. First, our results imply that researchers awareness of the importance of openness and transparency for scientific progress may complement stakeholders policies in achieving very high sharing rates. ...

Now the caviar grader comes to taste the caviar. There are three factors that the caviar is graded on. Each element is worth a point. First is the size of the eggs. Eggs between 3.2 -2.4 mm in diameter are given a point. Next are the pop and the taste. If the eggs pop well between your tongue and the roof of your mouth, they get a point. Then the taste will also receive a point - or not. The caviar now should have a grade of 0-3, which will determine the grade it receives: Classic, Royal, and if it is a Royal grade and is light in color, is graded as an Imperial,. Each tin will get a color dot that indicates what grade of caviar is in the tin. Even though color can vary from golden to black, it has nothing to do with quality and taste. Color is purely a preference of the individual, explains Struffenegger. ...

In the late 19th century, Americas waters were abundant with sturgeon and the German immigrant Henry Schacht was the first who took advantage. In 1873, he set up a business exporting caviar to Europe for the seemingly high price of one dollar per pound.[2] Other entrepreneurs soon followed, and by the end of the century, the United States consolidated their position as the largest exporter of caviar in the world.. The deceit become clearer when much of the harvest shipped to Europe was imported then back to the USA, labelled as Russian caviar, as the product that came from the Russian rivers had always been considered premium. In 1900, the state of Pennsylvania issued a report estimating that 90% of the Russian caviar sold in Europe was in fact produced and encased in the United States. This caviar boom brought sturgeon nearly to the point of extinction, on account of overfishing. By the 1960s, the prices were so high that new sources of domestic caviar had to be sought.. Contrary to popular ...

In the absence of any other conclusive forensic evidence, DNA profiling is the method of choice for body identification. This study focuses on the case of a carbonized corpse whose complete autosomal short tandem repeat (STR) profile could not lead to direct identification by the investigators. To assist in the progress of investigation, we endeavoured to determine the biogeographical origin and eye colour of the deceased individual. Along with Y chromosome and mitochondrial DNA analyses, we applied a next-generation sequencing (NGS) approach to the study of ancestry informative markers (AIMs) using the HID-Ion AmpliSeq™ Ancestry Panel launched by Thermo Fisher Scientific. This work gave us the opportunity to test this new technology in a real forensic case. Although this study highlights the benefits of such a combined approach, as it markedly improves the specificity of the biogeographical profile, it also underlines the need for the accurate characterization of a larger collection of reference

London: British Museum Press; 2014. 1 Introduction In various fields of medical biological criminology, there has been continuous progress in scientific methodology over the last century, accompanied by improvements in the forensic evidential value of the findings obtained. Examples of this progress are the new methods of chemical analysis in the field of toxicology with their highly specific and highly sensitive results, and the methodologic shift in forensic genetics - often seen as revolutionary - from blood groups to accurate identification by DNA analysis. It is quite remarkable that Hounsfield went in one jump from the primitive lathe bed apparatus to the prototype CT scanner. K. The first patient scanned was a 41-year-old woman with a possible frontal lobe tumor. The data were acquired, and the tapes were sent to EMI. The results were returned after 2 days. The cystic tumor in the left frontal lobe was clearly shown, and Ambrose said the result caused he and Hounsfield to jump up and ...

Digital forensics (sometimes known as digital forensic science) is a branch of forensic science encompassing the recovery and investigation of material found in digital devices, often in relation to computer crime. The term digital forensics was originally used as a synonym for computer forensics but has expanded to cover investigation of all devices capable of storing digital data. With roots in the personal computing revolution of the late 1970s and early 1980s, the discipline evolved in a haphazard manner during the 1990s, and it was not until the early 21st century that national policies emerged. Digital forensics investigations have a variety of applications. The most common is to support or refute a hypothesis before criminal or civil (as part of the electronic discovery process) courts. Forensics may also feature in the private sector; such as during internal corporate investigations or intrusion investigation (a specialist probe into the nature and extent of an unauthorized network ...

Identification of the population origin of an individual is very useful for crime investigators who need to narrow down a suspect based on specimens left at a crime scene. Single nucleotide polymorphisms of the Y chromosome (Y-SNPs) are a class of markers of interest to forensic investigators because many of the markers indicate regional specificity, thus providing useful information about the geographic origin of a subject. We selected seven informative Y-SNPs (M168, M130, JST021355, M96, P126, P196, and P234) to differentiate the three major population groups (East Asian, European, and African) and used them to develop forensic application.

The Y-DNA STR test is a useful technique used in ancestry, relationship and forensic applications. The test analyzes markers in the Y chromosome known as STRs or short tandem repeats. STR markers are short segments of DNA (2-13 nucleotides in length), which are repeated multiple times. STR analyses measure the exact number of repeat units. The number of repeats differs between individuals because STRs change frequently. The more closely related two individuals are along their direct paternal line, the more similar their Y-DNA STR profiles will be. Y-DNA STR tests can be used for forensic applications, investigating relationships, tracing distant male relatives who may have descended from the same paternal lineage and identifying links to famous people. It is a simple test that can provide you with rich information about your paternal lineage ...

Computer forensics (also known as computer forensic science) is a branch of digital forensic science pertaining to evidence found in computers and digital storage media. The goal of computer forensics is to examine digital media in a forensically sound manner with the aim of identifying, preserving, recovering, analyzing and presenting facts and opinions about the digital information. Although it is most often associated with the investigation of a wide variety of computer crime, computer forensics may also be used in civil proceedings. The discipline involves similar techniques and principles to data recovery, but with additional guidelines and practices designed to create a legal audit trail. Evidence from computer forensics investigations is usually subjected to the same guidelines and practices of other digital evidence. It has been used in a number of high-profile cases and is becoming widely accepted as reliable within U.S. and European court systems. In the early 1980s personal computers ...

Phylogenetic analysis may serve as a valuable tool in assessing the epidemiological relation between viral DNA sequences. In order to increase the likelihood of observing phylogenetic separation of sequences as well as to give strong forensic evidence regarding transmission, phylogenetic analysis needs to be performed on appropriate local control sequences and by sequencing of at least two genetic regions of reasonable length, depending on the gene under investigation. The aim of this study was to explore the suspected epidemiological linkage between DNA sequences isolated from three HIV-1 infected patients by means of phylogenetic analyses.. Phylogenetic analysis was performed on investigated sequences together with a number of local controls, that are viral sequences from infected individuals in the same location and diagnosed in a similar time period. Two genetic regions, of 1,6 kb for pol and 800 bp for env, were amplified and sequenced from viral RNA extracted from plasma. Transmission ...

GIST: Jeramie R. Davis continues to serve a nearly 40-year sentence for murder despite DNA evidence that raises questions about his guilt on the charge. A judge today granted the request for a new trial of a man convicted four years ago of the 2007 beating death of an adult bookstore owner in Spokane following the conviction two weeks ago of another man for the same crime. Superior Court Judge Greg Sypolt granted the request to hold a new trial for Jeramie R. Davis, 41, who was sentenced in 2008 to 40 years in prison for the first-degree murder of 74-year-old John G. Jack Allen, who was bludgeoned to death with a baseball bat inside his store on East Sprague Avenue. What remains unclear is whether Sypolt will vacate Davis conviction, Deputy Spokane County Prosecutor Dale Nagy said.........When a jury convicted Davis in 2008, Nagy told the jury to disregard the fact that DNA on baseball bat used to bludgeon Allen to death did not come back to Davis. Last year, that DNA evidence was again ...

On February 22, 2017, in Life Technologies Corporation v. Promega Corporation, the United States Supreme Court, in a 7-0 decision (with Chief Justice Roberts not participating) reversed the decision of the Federal Circuit, holding that the supply of a single component of a multi-component invention for manufacture abroad does not give rise to § 271(f)(1) liability. Because only a single component of the patented invention at issue here was supplied from the United States, the case was reversed and remanded to the Federal Circuit.. Promega Corporation (Promega) was the exclusive licensee of the Tautz patent, which claims a toolkit for genetic testing primarily used by law enforcement agencies for forensic identification and other clinical and research institutions.

Single nucleotide polymorphisms, frequently called SNPs (pronounced snips), are the most common type of genetic variation among people. Each SNP represents a difference in a single DNA building block, called a nucleotide. For example, a SNP may replace the nucleotide cytosine (C) with the nucleotide thymine (T) in a certain stretch of DNA.. https://isogg.org/wiki/Single-nucleotide_polymorphism. A short tandem repeat (STR) occurs when a pattern of two or more nucleotides are repeated and the repeated sequences are directly adjacent to each other. The pattern can range in length from 2 to 16 base pairs (bp). By identifying repeats of a specific sequence at specific locations in the genome, it is possible to create a genetic profile of an individual. Autosomal STR analysis has become the prevalent analysis method for determining genetic profiles in forensic cases. Y-chromosome STRs (Y-STRs) on the Y chromosome) are used in genealogical DNA testing in surname DNA projects.. Generally, STR loci are ...
The term familial searching has no well-established scientific meaning. As explained in David H. Kaye, The Genealogy Detectives: A Constitutional Analysis of Familial Searching, 51 Am. Crim. L. Rev. 109 (2013), kinship testing of possible parents, children, and siblings can be done with the usual autosomal STR loci used for criminal forensic investigation. When this technique is applied to a database (local, state, or national), it sometimes reveals that the crime-scene DNA matches no one in the database but is a near miss to someone -- a near miss in such a way as to suggest the possibility that the source of the crime-scene sample is a brother, son, or parent of the nearly-matching individual represented in the database. In other words, familial searching is the process of trawling a database for possible matches to people outside of the database -- outer-directed trawling, for short ...

Background The post-mortem interval (PMI) is the time elapsed since the dead of an individual until the body is found, which is relevant for forensic purposes. The miRNAs regulate the expression of some genes; and due to their small size, they can better support degradation, which makes them suitable for forensic analysis. In the present work, we evaluated the gene expression of miR-381-3p, miR-23b-3p, and miR-144-3p in skeletal muscle in a murine model at the early PMI. Methods We designed a rat model to evaluate the early PMI under controlled conditions. This model consisted in 25 rats divided into five groups of rats, that correspond to the 0, 3, 6, 12 and 24 hours of PMI. The 0 h-PMI was considered as the control group. Muscle samples were taken from each rat to analyze the expression of miR-381-3p, miR-23b-3p, and miR-144-3p by quantitative RT-PCR. The gene expression of each miRNA was expressed as Fold Change (FC) and compared among groups. To find the targets of these miRNAs and the pathways
The Korean Embassy passed fingerprint details of Koreans (all South Korean adults have their fingerprints recorded) to the North Yorkshire Police, and these confirmed her identity.. The police linked Hyo Jung Jins death to that of In Hea Song, another Korean student whose almost naked body was found in a cupboard in a house in East London. She had also been suffocated, and forensic scientists identified her body by matching her DNA profile with those of her parents (known as DNA kinship analysis). Money had been taken from both womens bank cards.. The houses where In Hea Songs body was found and the house where Hyo Jung Jin visited both had the same landlord - Kyo Soo Kim. Gilbert and George designed the tape used by the murderer to bind around Hyo Jung Jins face and body. This tape is only available in the four branches of the Tate Gallery in the UK, in London, Liverpool and Cornwall, and by this date, the Tate had only sold 851 rolls. The police found a roll of this tape at Kyo Soo Kims ...
