The testimony of Daniel Schumaker, accident and crime scene reconstructionist, began with information on his background and exactly what he does for a living. Schumaker explained that his job is to take facts from crimes and turn them into graphics in order to help explain certain occurrences. He uses various types of software to reconstruct these scenes into diagrams, such as a Sokkia Mobile Station and a laser surveying device.
Schumaker also uses a motion capture suit in order to help recreate these crime scenes. The suit contains 16 sensors that link up and communicate with a crash-test dummy on a computer screen. Every time a person in the suit moves, the exact actions are mimicked by the dummy on the screen in real time.
