In 2010 the St. Landry Sheriff’s Department welcomed a traffic accident reconstruction expert among its team as Captain Brian Hundley successfully completed a course on accident investigation and reconstruction. Especially in fatal accidents or in cases where there are no eye-witnesses, car crash experts can play a pivotal role in determining the most probable explanation for how the accident occurred.
In an investigation, a crash reconstruction expert must rely heavily on evidence gathered by the police at the accident scene. Although the expert can consider a variety of physical evidence, including the road layout and traffic markings, tire skid marks, and the damaged vehicles themselves that remain after the occurrence of the crash, much of the expert’s analysis must be based on observations made after the event. For this reason, it is critical that police officers who respond to an accident scene are extremely diligent in preserving and recording evidence once the medical needs of the victims are addressed.
The reconstruction expert will review photographs of the roadway and vehicles and obtain detailed measurements of the site in order to create a diagram of the situation. This diagram is important for establishing the vehicles’ positions both before and after the impact.
