International Association of Forensic Sciences • Book Ofabstracts 2008 International Association of Forensic Sciences International Association of Forensic Sciences • Book of Abstracts 2008 International Association of Forensic Sciences International Association of Forensic Sciences 18th Triennial Meeting New Orleans, Louisiana, USA July 21-25, 2008 Book of Abstracts International Association of Forensic Sciences 18th Triennial Meeting BOOK OF ABSTRACTS The Book of Abstracts of the International Association of Forensic Sciences (IAFS) is devoted to the publication of the abstracts of technical oral papers and posters presented at the IAFS triennial meeting. These include various branches of the forensic sciences such as computer forensics, criminalistics, engineering, pathology, physical anthro- pology, psychiatry, odontology, toxicology, questioned documents. Similar submissions dealing with forensic oriented aspects of the social sciences are also included. Please note that some of the abstracts deal with topics, results, and/or conclusions which are controversial. The publication of abstracts does not necessarily imply that the IAFS or the individual program chairs/committee have verified or agree with the studies, results, and/or conclusions of each abstract. During the process of planning a sci- entific program, it is impossible to “peer-review” each abstract and presentation to the degree that is accomplished dur- ing manuscript review. Abstracts and presentations are accepted, in part, so that they can be critiqued and reviewed by other scientists, and so that a forum is available to discuss controversial issues. The views expressed in this publication are not those of the IAFS. The data and opinions appearing in the published material were prepared by and are the responsibility of the contributor(s), not the IAFS or its respective officers and agents. The IAFS does not supply copies of meeting papers and it is suggested that you write directly to individual au- thors to obtain copies of specific papers. Presentation of some abstracts may have been scheduled or canceled after the publication of this document. Unless stated otherwise, noncommercial photocopying of editorial material published in this periodical is permitted by IAFS. Permission to reprint, publish, or otherwise reproduce such material in any form other than photocopying must be obtained by IAFS.

Goldberger, PhD*, University of Florida, Department of Pathology, College of Medicine, 4800 Southwest 35th Drive, Gainesville, FL 32608; Robert D. Blackledge, MS*, Retired Forensic Chemist, 8365 Sunview Drive, El Cajon, CA 92021 Floyd Landis, a professional bicycle racer from Murrieta, California, won the 2006 Tour de France. However, not many days after the race’s conclusion, the Laboratoire National de Dépistage du Dopage (LNDD) “announced” (actually the information was leaked to the press) that a urine sample obtained from Floyd after stage 17 had been found to be positive for a form of synthetic testosterone. If this finding were to be upheld, Landis would be stripped of his title and also banned from participation in the sport. Landis denied any sports doping and his strategy in fighting these charges has been to try to generate public support and to make all of the documentation of the LNDD tests available to the public. GC/MS is used by LNDD for preliminary sample screening, and carbon stable isotope ratio mass spectrometry is used for final confirmation. From the standpoint of a forensic analytical chemist with experience in forensic laboratory accreditation standards, this presentation will examine the analytical data and correspondence from the Landis case in terms of chain of custody requirements, World Anti-Doping Association (WADA) guidelines and LNDD SOP, and reasonable standards of good laboratory practice.

Nevertheless, it’s highly worthy to investigate the genetic information of these populations with molecular genetics approaches in order to preserve the genetic resource and polymorphism within this region. To characterize the genetic differentiation and evolution of 16 different populations and 12 independent minorities, nine autosomal STRs, which are widely applied in forensic science, were selected; then several statistical methods, such as principal component analysis, phylogenetic trees, R matrix analysis, and Mantel tests were processed in parallel with allele and genotype frequency data. The results of principal component analysis showed that five minority populations living in Xinjiang were clearly separated from other populations. Topologically, the branch of phylogenetic trees was in coordinate with linguistic affiliation. Regression plot of R matrix model suggested most populations had the similar patterns of gene flow at an average level, with the exception of Hui in Qinghai, which received more gene flow from outside. Unexpectedly, results of Mantel test showed that the correlation between genetic distance and linguistic distance (r=0.5040, p=0.0054) was more dominant than genetic distance and geographic distance (r=0.0022, p=0.4950), which represents that linguistic difference contributed more to genetic differentiation than geographical isolation.

  • Voices of Forensic Science
    Chapter 3 The Contamination and Misuse of DNA Evidence Vanessa Toncic, Alexandra Silva "Genes are like the story, and DNA is the language that the story is written in." (Kean, 2012) To understand how potentially mishandled or contaminated DNA evidence could be manipulated or presented in court, (under false pretenses), as an evidentiary ‘gold standard,’ it is important to first explain why, and under what circumstances, DNA evidence is in fact a gold standard. DNA evidence may be disguised as a gold standard when either the techniques used, or the representation of the data has been skewed and is no longer reflective of DNA as a gold standard. This chapter will explore the use of mixed DNA profiles as well as low copy number (LCN) techniques of DNA analysis, and how these methods may not be deserving of the ‘gold standard’ seal associated with DNA evidence. We will explore the biological aspect of issues with these methods and how they may reflect a contaminated DNA sample. Notably, DNA evidence that has been appropriately collected and analyzed may still be purposely misrepresented to a judge and/or jury. DNA as an evidentiary gold standard requires proper handling from the onset of collection, throughout analysis and storage, as well as during presentation in court to ensure that the quality of evidence is upheld. DNA evidence and its associated challenges are multi-faceted areas of study. These studies include issues surrounding the collection as well as the analysis of evidence leading to subsequent contamination and root cause analysis. There also exists debate on the ethics and privatization of DNA given the popularization of online DNA databases.

    UNIVERSITY OF LAUSANNE FACULTY OF LAW AND CRIMINAL JUSTICE SCHOOL OF CRIMINAL JUSTICE FORENSIC SCIENCE INSTITUTE The Relationship between Forensic Science and Judicial Error: A Study Covering Error Sources, Bias, and Remedies PhD thesis submitted to obtain the doctoral degree in forensic science Beatrice SCHIFFER Lausanne, 2009 To my family, especially my parents Summary Forensic science - both as a source of and as a remedy for error potentially leading to judicial error - has been studied empirically in this research. A comprehensive literature review, experimental tests on the influence of observational biases in fingermark comparison, and semi- structured interviews with heads of forensic science laboratories/units in Switzerland and abroad were the tools used. For the literature review , some of the areas studied are: the quality of forensic science work in general, the complex interaction between science and law, and specific propositions as to error sources not directly related to the interaction between law and science. A list of potential error sources all the way from the crime scene to the writing of the report has been established as well. For the empirical tests , the ACE-V (Analysis, Comparison, Evaluation, and Verification) process of fingermark comparison was selected as an area of special interest for the study of observational biases, due to its heavy reliance on visual observation and recent cases of misidentifications. Results of the tests performed with forensic science students tend to show that decision-making stages are the most vulnerable to stimuli inducing observational biases. For the semi-structured interviews, eleven senior forensic scientists answered questions on several subjects, for example on potential and existing error sources in their work, of the limitations of what can be done with forensic science, and of the possibilities and tools to minimise errors.

Since the end of the 18th century footwear impression comparison has been applied to assist in crime investigations. By examining the characteristics of a footwear impression the forensic scientist may provide the investigator with valuable information about the footwear and sometimes even about the wearer. Ultimately, the footwear impression is so unique that it can be individualized and identified to a specific shoe. In order to facilitate and improve the forensic evidence evaluation it is of great interest to statistically establish the prevalence of evidence. By collecting data of outsole patterns and then recording it in a database the strength of a specific footwear impression can be determined.

GIANNELLI.PTD 12/17/2007 2:47:57 PM WRONGFUL CONVICTIONS AND FORENSIC SCIENCE: THE NEED TO REGULATE CRIME LABS* PAUL C. GIANNELLI** DNA testing has exonerated over 200 convicts, some of whom were on death row. Studies show that a substantial number of these miscarriages of justice involved scientific fraud or junk science. This Article documents the failures of crime labs and some forensic techniques, such as microscopic hair comparison and bullet lead analysis. Some cases involved incompetence and sloppy procedures, while others entailed deceit, but the extent of the derelictions—the number of episodes and the duration of some of the abuses, covering decades in several instances—demonstrates that the problems are systemic. Paradoxically, the most scientifically sound procedure—DNA analysis—is the most extensively regulated, while many forensic techniques with questionable scientific pedigrees go completely unregulated.
