Webinar Synposis:

ACE-V has been called many things over the years, the least as a way to explain the steps or phases used by Latent Print Examiners when conducting latent print comparisons.

This presentation explains these steps in detail. With the bulk of time being spent on the “A” analysis as it is the most important part of the process. The least amount of time will be spent on the “E” evaluation phase as conclusions change from different agencies as well as different countries.

Topics covered:

  • Orientation clues for finger and feet
  • False ridge detail
  • Detection of forged or fabricated prints
  • Suitability
  • Distortion
  • Simultaneous Impressions
  • Rarity / weight / tolerance

Sandra Siegel started her fingerprint career with the Texas Department of Public Safety in the Crime Records Ten-Print Section. She started teaching in 1997 and was responsible for training the technical aspects of pattern interpretation, classification, identification, and AFIS operations. In December 2002 she took a position as a Latent Print Examiner with the Austin Police Department conducting AFIS searches, bench work in latent prints. In 2014 she accepted a position with the newly formed Houston Forensic Science Center as a senior latent print examiner. Sandy continues to train all aspects friction ridge skin identification and comparison.

Sandra is a member of the International Association for Identification, the Texas and Chesapeake Bay Divisions of the IAI. She is a Distinguished Member with the IAI and has served on the science and practice committees for processing and ten-prints. With the TDIAI, she served on the Program, Education, Resolution and Membership committees. Sandy obtained her IAI certification for latent prints in 1997. She is also the coordinator for the QUIP section for the Journal of Forensic Identification and moderator for an informal email group called FIGS (Fingerprint Interest Group by Sandy) which is dedicated to sharing all aspects of forensics related information.

Webinar: An introduction to Human Gait, its analysis and use as evidence

When: 25 Apr 2018 12:00 PM, UTC+01:00





An introduction to Human Gait, its analysis and use as evidence (2 hour webinar)

Professor Ivan Birch, Sheffield Teaching Hospitals NHS Foundation Trust


Gait analysis is now an established contributory option in the process of identification as part of criminal investigations. As the number of CCTV cameras in operation, and widespread use of video facilities on hand held devices, continue to increase, the use of gait analysis as an aid to identification is also likely to increase. Fundamental to the use of gait as evidence is a thorough understanding of the human locomotor process and gait.


This workshop will give consideration to the basic principles of human movement, locomotion and gait, and the mechanisms and processes by which they are initiated and controlled. Participants will be guided through the human gait cycle and develop an understanding of the events and phases that provide the basic spatial and temporal landmarks for gait analysis. Consideration will be given to how and why human gait varies from step to step and from person to person, and how it can therefore be utilised as a contributor to identification.


When: April 25th, Noon-2pm GMT or 8am - 10am EST 




Professor Ivan Birch is Consultant Expert Witness in forensic gait analysis with Sheffield Teaching Hospitals NHS Foundation Trustand Emeritus Professor of Human Sciences.Ivan graduated in 1978 with a BSc Joint Honours in Science from the University of Salford, gained an MSc in Human Biology from the University of Loughborough in 1980, and was awarded a PhD in Biomechanics by the University of Brighton in 2007. He has extensive experience of teaching biomechanics, anatomy, physiology and research methods, and is a Professional Member of the Chartered Society of Forensic Sciences. In 2015 he was awarded the status of the Chartered Scientist by the Science Council and College of Podiatry in the UK for his work in gait analysis as evidence. Ivanis included on the National Crime Agency Specialist Operations Centre Expert Witness Advisers Database in the UK, and has more than 35 years’ experience of gait analysis.
