Criminal profiling is defined as an investigative and behavioral tool that is aimed at assisting those in the investigative field in profiling criminal offenders who are in most cases unknown. Criminal profiling goes by many names, such as: offender profiling, criminological profiling, criminal investigative analysis, criminal personality profiling and behavioral profiling. Criminal profilers are agents that study and analyze the behavior of an unknown criminal based on information that is gathered by his or her kills. The Federal Bareau of Investigation, or the Behavioral Analysis Unit rely on criminal profilers to provide psychological profiles of the offender. Technically, there is no official job title in the F.B.I called “criminal profiler.”
