![]() FoCoSS Forensics can also evaluate the crime scene processing techniques used for developing, documenting and preserving questioned tire tracks. Questioned tire tracks may also provide additional information such as what direction the vehicle was moving and how many vehicles may have been in that area.įoCoSS Forensics has court-qualified tire track examiners who can conduct independent tire track examinations or conduct re-examinations of prior comparisons for accurate findings. A conclusion of the resulting comparison can be rendered that associates a questioned tire track as having been made by a particular known tire. ![]() The book explains and illustrates the necessary information on obtaining known exemplars tire manufacturing, and retreading. They will also take photographs later be used to prove a match. For both the crime scene technician and the forensic examiner, the author addresses information on both how to recover tire track evidence and how to photograph and cast the individual tread detail from those impressions. Investigators may make ink prints of a tire or track. Tracks help investigators identify the type of vehicle that left them. At a crime scene, a questioned tire track can be documented, collected and subsequently compared to known tires. Tire Tracks Tire tracks are usually found in road scenes or in the access and escape crime scenes. As a tire travels across a surface, it is possible that a tire track can be left in that area. These random occurrences in the tread design are referred to as individual characteristics and are unique to each tire. A tire may also acquire random damage such as cuts and nicks in specific elements of the tread design. There are four main methods of collecting evidence of shoeprint, footprint, or tire track: 1. When vehicle tires are driven on, they can accumulate material such as glass and/or small stones randomly embedded in the tread design. Tires that share the same tread design are referred to as having the same class characteristics. The tread design encircles the entire circumference of the tire and is the part of the tire that contacts the surface on which the vehicle is traveling. Tire Track Impression Examination, Comparison, Identification, Expert Witness In an ever-changing field, FoCoSS Forensics strives to stay ahead of the curve. Part of the tire manufacturing process involves the making of a tread design. Tire tracks have the potential to provide solid forensic associations to a vehicle, however, this type of evidence is often underutilized. Tire Impressions reflect the tread design and dimensional features of individual tires on a vehicle Tire Tracks are relational dimensions between two or.
