Accident reconstruction is a well known science where experts still disagree when it comes to the details. Subtle changes in your assumptions can produce significantly different results in your analysis. Mr. Hille has reconstructed over one thousand accidents during the last twenty plus years. Many of these reconstructions were performed strictly to check the work of the reconstruction people for both sides in pending cases, and as such were done in a simplified manner. Trained by the Institute of Police Technology and Management (IPTM) based out of the University of North Florida in 1990, he has continued to keep his hand in the methods and practices used. His work with the relatively new crash data recorders is enhanced by his years of reconstruction experience.
