TYPES OF IMPRESSION EVIDENCE

Remember that the definition of impression evidence involves a donor and a recipient. The donor contains some three-dimensional markings and the recipient is made of a material that can form and hold a negative image of the donor markings. Common donors that occur as evidence in crimes include shoe soles and heels, tire treads, fingerprints and other friction ridges such as footprints and lip prints (discussed in the chapter on Fingerprints), tools that leave markings on the objects on which they are used (discussed in the chapter on Firearms and tool marks), metal dies that are used to make serial numbers, ribbing and texture in fabrics, etc. Common recipients include soft plastics, soil, putty, paint, dust, metals, and some soft plastics. Bite marks are also a type of impression evidence and this will be discussed later in the chapter.
