American Academy of Forensic Sciences 410 North 21st Street Colorado Springs, Colorado 80904 Phone: (719) 636-1100 Email: [email protected] Website: www.aafs.org @ AAFS Publication 20-2 Copyright © 2020 American Academy of Forensic Sciences Printed in the United States of America Publication Printers, Inc., Denver, CO Typography by Kathy Howard Cover Art by My Creative Condition, Colorado Springs, CO WELCOME LETTER Dear Attendees, It is my high honor and distinct privilege to welcome you to the 72nd AAFS Annual Scientific Meeting in Anaheim, California. I would like to thank the AAFS staff, the many volunteers, and everyone else who have worked together to create an excellent program for this meeting with the theme Crossing Borders. You will have many opportunities to meet your colleagues and discuss new challenges in the field. There are many workshops and special sessions that will be presented. The Interdisciplinary and Plenary Sessions will provide different views in forensic science—past, present, and future. The Young Forensic Scientists Forum will celebrate its 25th Anniversary and is conducting a workshop related to the meeting theme. More than 1,000 presentations are scheduled that will provide you with more insight into the developments in forensic science. The exhibit hall, always interesting to explore, is where you will see the latest forensic science equipment, technology, and literature. The theme Crossing Borders was chosen by me and my colleagues at the Netherlands Forensic Institute (NFI). We see many definitions of crossing borders in forensic science today. For the 2020 meeting, six words starting with the letters “IN” are included in the theme. We start with International, since it is linked to crossing borders. Next, Interdisciplinary, because so many different disciplines are now working together. We include Intelligence, as we see that the combination of different fields, such as criminalistics and artificial intelligence, may provide new opportunities. Inclusiveness is also one of the topics that is addressed very well by the AAFS, and additionally looks to diversity within the organization. We should include different opinions on a scientific basis, keeping in mind Integrity and Independence. I value our members very much, and I believe we should be inclusive regarding different opinions; we should foster our international members, young and old, and all members, maintaining high standards of integrity in forensic science as well as being respectful to each other, even if opinions diverge. Last, but not least, Crossing Borders means finding new solutions that are often interdisciplinary, combining different fields, and finding new methods to solutions—for example, thinking of artificial intelligence as well as forensic intelligence. Currently, we see great progress in artificial intelligence, as computing power is faster and cheaper; however, one of the issues in this instance is explainability in court. Safe travels and I look forward to seeing you in Anaheim. Warmest regards, Zeno Geradts, PhD 2019-2020 President 2 TABLE OF CONTENTS About the AAFS . 4 General Information ........................................................................... 5 Officers & Officials ............................................................................. 6 Program Committee ............................................................................ 8 Past Award Recipients........................................................................... 9 2020 Distinguished Fellows ..................................................................... 10 Awards ...................................................................................... 12 Section Business Meetings ..................................................................... 14 Receptions ................................................................................... 14 Continuing Education ......................................................................... 15 Financial Contributors ........................................................................ 18 Guidebook Mobile App ........................................................................ 19 Student Academy ............................................................................. 20 Interdisciplinary Symposium ................................................................... 21 Young Forensic Scientists Forum Special Session .................................................. 24 Forensic Science Education Programs Accreditation Commission Session ............................ 27 Evening Session .............................................................................. 29 Academy Cup ................................................................................ 30 Plenary Session ............................................................................... 31 Breakfast Seminars ............................................................................ 33 Luncheon Seminars ........................................................................... 40 Workshops ................................................................................... 42 American Society of Forensic Odontology ........................................................ 94 National Institute of Justice ..................................................................... 95 National Association of Medical Examiners ....................................................... 97 Humanitarian and Human Rights Resource Center Poster Session ................................... 98 Scientific Sessions Anthropology ............................................................................... 103 Criminalistics ............................................................................... 120 Digital & Multimedia Sciences ................................................................. 144 Engineering & Applied Sciences ............................................................... 150 General ..................................................................................... 156 Jurisprudence ............................................................................... 167 Odontology ................................................................................. 171 Pathology/Biology ........................................................................... 177 Psychiatry & Behavioral Science ............................................................... 195 Questioned Documents ....................................................................... 200 Toxicology .................................................................................. 204 Last Word Society ............................................................................ 213 Young Forensic Scientists Forum Poster Sessions ................................................. 214 Program Committee Financial Disclosure ....................................................... 217 Presenting Author Financial Disclosure ......................................................... 220 Key Word Index ............................................................................. 234 Presenting Author Index ...................................................................... 249 Notes ....................................................................................... 257 3 ABOUT THE AAFS For 72 years, the American Academy of Forensic Sciences (AAFS) has served a distinguished and diverse membership. Its 6,600+ members are divided into 11 sections spanning the forensic enterprise. Included among the Academy’s members are physicians, attorneys, dentists, toxicologists, anthropologists, document examiners, digital evidence experts, psychiatrists, engineers, physicists, chemists, criminalists, educators, and others. Representing all 50 United States, Canada, and 60 other countries worldwide, they actively practice forensic science and, in many cases, teach and conduct research in the field as well. Each section provides opportunities for professional development, personal contacts, awards, and recognition. Many sections publish AAFS Newsfeed articles that keep their members abreast of activities and developments in their fields. As a professional society dedicated to the application of science to the law, the AAFS is committed to the promotion of education and the elevation of accuracy, precision, and specificity in the forensic sciences. It does so via the Journal of Forensic Sciences (its internationally recognized scientific journal), the AAFS Newsfeed, its annual scientific meeting, the conduct of seminars and meetings, and the initiation of actions and reactions to various issues of concern. For its members and affiliates, AAFSprovides expert witness referrals, job opportunity listings, as well as scientific reference studies. As the world’s most prestigious forensic science organization, the AAFS represents its membership to the public and serves as the focal point for public information concerning the forensic science profession. Founded in 1948, the AAFS is headquartered in Colorado Springs, CO. AAFS Annual Scientific Meeting Each February, the AAFS scientific meeting gathers together approximately 5,000 world-renowned professionals to present the most current information, research, and updates in their fields. More than 1,000 scientific papers, seminars, workshops, and other special sessions are presented. In addition, approximately 150 exhibitors showcase the cutting-edge technology and services of this ever- changing profession.
