ABSTRACT
Tires leave their impressions over a multitude of surfaces such as snow, dirt roads and shoulders, and other unpaved areas. A tire may also leave a grazing mark of its sidewall or tread against the shirt of a hit-and-run victim or produce a blunt force injury that leaves a contusion that replicates its tread pattern on the skin of the victim’s body. At some scenes, tire impressions may be short and isolated. Other scenes may include long impressions of all four tires. The examination of these impressions can place the perpetrator’s vehicle at the scene of the crime but, in order to benefit from the full potential of this evidence, these impressions need to be recovered properly and their location and relationship to the crime scene must be properly documented.
