Evidence preservation is a crucial step in any accident investigation. Shortly after an accident, the quality of the physical evidence will begin to degrade with time. In automobile accidents tire marks can start to disappear within hours. Quickly preserving the evidence will allow the investigator to provide accurate answers in a timely manner. Our team of forensic specialists have extensive training in evidence preservation. This includes imaging data from event data recorders (EDRs), surveying the physical evidence at the scene, surveying the geometry of the roadway, measuring vehicle dimensions, and more.
