CHAPTER 7 Pre-Test Introduction I n this and following chapters, we will discuss pattern evidence. Many of the topics concern patterns for individualization, including physical patterns, fingerprints, foot- prints, footwear and tire impressions, handwriting, firearms and tool mark identifica- tion, bitemarks, and bloodstain patterns. This chapter looks closely at physical patterns (broken or torn objects) and fingerprints (a major category of individualization pattern). Pattern evidence can be very important in an investigation, because it includes many types of evidence familiar to most people. Some types of patterns can potentially be individualized—that is, attributed to a specific source. In this way, people can be asso- ciated with or dissociated from specific places, like scenes, or from other people. Con- clusions from pattern evidence comparisons are usually more definitive than those from trace or chemical evidence, and correspondingly more useful to juries and judges. Pat- tern evidence is examined by the eye, for the most part. No complicated instruments, other than the occasional use of microscopes, are required. Sometimes, a pattern evidence match can be obvious to anyone, such as in a physical pattern match (jigsaw fit), making the evidence easier to present to a court. Pre-Test 1.
