Forensic techniques have been developed based on biased race determination methods that do not work. Problems are then created when discussing the topic of race because race can mean many different things to any one individual, especially to anthropologists who cannot find a common methodology to determine “race” within these police investigations. Due to this, the computer software accuracy of AncesTrees and Fordisc used be forensic anthropologists in these investigations has come into question. This thesis explores the use of race within forensic anthropology and criminology (specifically police forces). The results from this thesis show that race is a social construct and promotes racialization for investigators and forensic anthropologists and does not prove to be beneficial in identification investigations. iv DEDICATION To my loving and supportive mother and father – thank you for being there for me throughout my academic journey. Everything that I have accomplished is because of the love and belief that you had in me and for that, I am truly grateful. Without the two of you, none of this would have been possible. To my amazing brother and sister – thank you for always being an inspiration, even if you were not aware of it. I will forever have two best friends who I will love unconditionally and continue to guide and assist in all your life’s adventures. To my incredible grandparents – thank you for your prayers and wise words to help me realize that I can achieve anything I put my mind to. Your stories and lives have continued to provide me wisdom and guidance and I will always cherish all the lessons you have taught me. To all those who have been there for me throughout this chapter – thank you for always supporting and encouraging me to get where I am today. v ACKNOWLEDGEMENTS First, I’d like to thank my advisor, Dr. John Albanese, for all of his support and confidence in me. Your interest and valuable guidance has allowed for me to do this research with confidence and hope that this could be the beginning of a great topic trend within forensics and anthropology. Your input and encouragement was and is always appreciated. I would also like to thank the other members of my committee, Dr. Jane Ku and Dr Catherine Hundleby for their interest in and their commitment to my research. Both of their input and suggestions were greatly appreciated. Finally, to all of my peers and colleagues in the graduate program, thank you for the support and encouragement throughout this process. vi TABLE OF CONTENTS DECLARATION OF ORIGINALITY .......................................................................... iii ABSTRACT ...................................................................................................................... iv DEDICATION ...................................................................................................................v ACKNOWLEDGEMENTS ............................................................................................ vi LIST OF TABLES ......................................................................................................... viii LIST OF FIGURES ......................................................................................................... ix Introduction ........................................................................................................................1 Background and Literature Review .................................................................................4 Methodology .....................................................................................................................15 Results ...............................................................................................................................19 Discussion .........................................................................................................................20 Conclusion ........................................................................................................................24 References .........................................................................................................................25 Appendix A: Table of Cranial Measurements Used .....................................................37 Appendix B: Excel Spreadsheet with Specimen ID and Cranial Measurements ......38 Appendix C: AncesTrees Computer Program ..............................................................39 Appendix D: Fordisc Computer Program .....................................................................40 Appendix E: Results ........................................................................................................41 Appendix F: Tables of Populations in Fordisc ..............................................................43 Vita Auctoris .....................................................................................................................45 vii LIST OF TABLES Table 1: Accuracy of AncesTrees for Group One and Two 41 Table 2:Accuracy of Fordisc using Howell's Data for the Top Two Groups 41 Table 3:Accuracy of Fordisc using FDB for the Top Group 41 Table 4: Maximum number of cases in Forensic Data Bank Groups 43 Table 5: Table of Howell's Groups in Fordisc 44 viii LIST OF FIGURES Figure 1: AncesTrees Number of Possible and Not Possible Race Prediction 19 Figure 2: Fordisc using Howell's Data of Possible and Not Possible Race Prediction 19 Figure 3: Description of standard osteological measurements 37 Figure 4: Excel spreadsheet provided by Dr. John Albanese 38 Figure 5: Howell's 30 Measurements used in AncesTrees 39 Figure 6: Fordisc – Howell’s Databank 40 Figure 7: Fordisc – FDB 40 Figure 8: AncesTrees Results page 42 Figure 9: Fordisc – Howell’s Databank Results page 42 Figure 10: Fordisc – FDB Results page 42 ix Introduction Forensic anthropology
