Evidence preservation is a crucial part of any investigation. Shortly after an accident, the quality of the physical evidence begins to degrade — in automobile accidents, tire marks can disappear within hours. Quickly preserving the evidence allows the investigator to provide accurate answers in a timely manner. Our forensic specialists have extensive training in evidence preservation, including imaging data from event data recorders (EDRs), surveying the physical evidence at the scene, surveying roadway geometry, and measuring vehicle dimensions.
