ABSTRACT
This chapter discusses the specific types of evidence that will enable first unit responders to be more specific in their description of evidence. Evidence can be categorized by its composition or type, and further subdivided into specific types. All evidence will belong to one of four general categories. Any evidence transferred from the suspect to the victim, the suspect to the scene, the victim to the suspect, or the victim to the scene. Transfer evidence is quite common in crimes of violence where a struggle has taken place and evidence was left behind. An object that has made an indentation or impression on another surface. Examples of this type of evidence would be tire or footwear impressions in mud or dirt; impressions left in snow; and/or fingerprints in paint or a clay-like substance. Marks left on objects scraping together, where one object is harder than the other.
