ABSTRACT
This chapter provides a comprehensive account of how behavioural analysis for criminal profiling evolved over the past century, how the Federal Bureau of Investigation (FBI's) Behavioural Science Unit (BSU) formed, who its founding personnel were. The BSU had a distinct set of goals: crime scene analysis, criminal profiling, and the analysis of threatening letters. Although behavioural profiling is not exclusive to serial crimes or to murder, it is used more often for linkage analysis than any other aspect of behavioural interpretation of a crime scene. With the growing sophistication of scientific inventions, industrial technology, and medical discoveries occurring parallel to the waning dominance of religion, physicians needed cadavers to advance their knowledge about disease and to teach human anatomy to medical students, so they encouraged grave robbing. The BSU eventually became the Behavioral Analysis Unit (BAU), spreading out into an investigative or field unit that could actively assist local jurisdictions.
