This is a pocket-sized key to a guide which classifies the three major felonies - murder, arson and sexual assault, based upon the motivation of the offender. The guide attempts to standardize the language and terminology used throughout the criminal justice system. It should provide police officers, detectives, homicide investigators, and other law enforcement personnel, in any size community, access to the same information as used by the FBI to coordinate their investigations. The guide forms the basis of contemporary investigative profiling, the acclaimed strategy enebling law enforcement personnel to solve a crime by generating a profile of the suspect. Drawing from such disciplines as nursing, psychiatry, and psychology, each of the three crime classification groups reflect current relevant research on actual criminal cases. Each classification includes an in-depth case study, which analyses an actual crime, giving users examples of specific crime scene characteristics to look for. The CCM will facilitate communication within criminal justice and mental health professionals. Furthermore, it develops a database for investigative research.
