In the early 2000s, the book author, Dr. Janet Oliva, and her colleague, Keith Howard, (then) Special Agents of the Georgia Bureau of Investigation (GBI), were contacted by a local district attorney’s office about a series of sexual assaults that had occurred in the Atlanta, Georgia area. Both agents were assigned to the GBI’s Crime Analysis Unit, which housed the Behavioral Science Section of criminal profilers. In addition to serving as special agents for the GBI, Dr. Oliva and Mr. Howard were both criminal profilers with the International Criminal Investigative Analysis Fellowship (ICIAF). The criminal prosecutor requested assistance from the agents in conducting a linkage analysis of eight criminal cases to determine whether one or more of the crimes had been committed by the same offender.
