Postmortem interval

Dr. Leon Higley’s work to characterize blow-fly species indicates that there is variation within a single population--the bell curve is wide. Dr. Higley will share his research and discuss how the science is challenging some notions about PMI analysis.

Insect evidence can provide valuable information during death investigations. Forensic entomologists estimate the ages of the immature insects like blow flies, which can provide useful information regarding timelines in death investigations.

Part I: GeoFOR is a free web-based collaborative forensic taphonomic application and database that utilizes geospatial technology and machine learning to deliver data-driven postmortem interval estimations to better facilitate identification and reconstruct events around the time of death. This presentation describes the geoFOR application and its potential for advancing the field of forensic science.  

The Transition Analysis 3 (TA3) age-at-death estimation method was developed as part of an international research project supported by National Institute of Justice (NIJ) award #2014-DN-BX-K007. This presentation provides a brief history of the TA3 project from its beginnings in the late 1990s to its current status two decades later. Participants learn about the iterative process used to identify traits and develop definitions and are introduced to the TA3 trait manual and generic data collection form.
