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.
