This presentation will address challenges encountered while documenting motor vehicle crashes. We will review the kinds of technology that can be applied to correct commonly observed misapplications, mistakes, and incorrect processing to ensure your agency doesn’t waste its budget on the wrong equipment. How to make a better investigator through understanding the science behind the different measurement methodologies – Cartesian, trilateration, and photogrammetry using modern robotic total stations, GPS, laser scanners terrestrial photography and aerial imagery – will also be discussed.

A Case in Review: Vehicular Homicide Cases (Dale Drummond)

He'll explore the data available on today’s vehicles and how crash investigators can rely on this information to corroborate traditional methods or use as a stand-alone resource when other evidence is absent. He’ll demonstrate how the Berla iVe system can be used to identify supported vehicles, perform data acquisitions, and conduct data analysis, including historical vehicle locations and speed, phone calls and text messages, and vehicle events (doors opening/closing, gear shifts, voice commands, and etc.).

Video Analysis for Collision Reconstruction (Bobby Mullinax)

- Bobby J. Mullinax, Instructor, South Carolina Criminal Justice Academy

Bobby Mullinax will introduce you to a simple, user-friendly method of analyzing video sources using photogrammetry software and multiple video frames. The process, which works on most video sources, will allow for key pieces of evidence to be quickly extracted from crashes, including vehicle position and velocity, post-crash videos for diagramming purposes, and video of officer-involved incidents to extract evidence or suspect information such as height.

2019 EDR

Case Studies Using EDR Information (Richard Ruth)
