These techniques are presented in the context of how they are used to solve crimes. The authors explain how to use bloodstain patterns to understand events that occurred at a crime scene, which includes a discussion of the role of logic in analysis. The book includes practical information on documenting and collecting bloodstain pattern evidence, presenting evidence in court, and contending with bloodborne pathogens. The book includes a specific methodology for crime-scene reconstruction and provides an in-depth discussion of how investigators can use bloodstain patterns to define events associated with a given crime scene. It defines terms used in bloodstain analysis and includes many photographs to depict the terms discussed. Historical examples show the use of bloodstain pattern analysis in solving crimes. Appendixes contain a weight/measure conversion table and discussions of trigonometric functions and their application in bloodstain pattern analysis, as well as stop- motion photography techniques.
