My name is Daniel Holmes and I am retired from the Minnesota State Patrol with nearly 27 years of experience. While working for the Minnesota State Patrol I reconstructed over 170 serious or fatal crashes. I have also investigated over 1,500 motor vehicle crashes that did not rise to the level of requiring a crash reconstruction. In 2015, I was awarded the Minnesota State Patrol Award of Excellence in Crash Reconstruction for my work. I am A.C.T.A.R. ( National Accreditation Commission for Traffic Accident Reconstruction) certified. I am trained as a C.D.R. ( Crash Data Recorder) analyst-technician and have the ability to image and analyze the airbag data from supported vehicles. I am a Forensic Mapper and drone operator. I have the ability to generate scaled diagrams from a crash scene or use mapping data obtained from Law Enforcement. I am also trained in Occupant Kinematics, and have reconstructed several pedestrian/bicycle accidents along with commercial vehicle crashes....
