ABSTRACT
One of the primary functions of the analyst is to define or categorize the specific stains and patterns found. Once these are categorized, the analyst then attempts to identify the underlying nature of the event causing the pattern. An important pattern found at many crime scenes is the spatter pattern. As defined in Chapter 3, spatter is a stain resulting from some application of force or energy to a blood source. As definitive as this is, unfortunately there is little agreement on how to differentiate spatter. What is generally agreed is that spatter patterns often help us identify the nature of the force involved in the event.
