Inductive Criminal Profiling
The process of profiling criminal behavior, crime scenes, and victims from the known behaviors and emotions suggested by other criminals, crime scenes, and/or victims.
In essence, as the term suggests, this is reasoning from initial statistical data to specific criminal offender behavior. In any event, Inductive Criminal Profiling is generally the result of some kind of statistical analysis, or finds it's reasoning in cases outside of the case at hand.
Example
80% of known serial killers that attack college students in parking lots are white males age 20-35 who live with their mothers and drive Volkswagen Bugs-- Our offender has attacked at least three female college students on separate occasions; our offender has attacked all three victims in parking lots.
Therefore, our offender, who is part of this large group who fit this "profile" called "serial killers" is a white male age 20-35, lives with his mother, and drives a VW Bug.
Deductive Criminal Profiling
The Behavioral Evidence Analysis a specific criminal, crime scene(s), and victim(s) exclusively from forensic evidence relating to the crime scene(s) and victim(s) of that offender alone.
Example
The body of a female victim is found nude in a remote forest location with 4 shallow, careful incisions on the chest, cutting across the nipples. The victim's genital areas have all been removed with a sharp instrument. Petechiae are evident in the eyes, neck and face above pattern compression on the neck. No blood is found at the crime scene. No clothes are found at the crime scene. The victim bears ligature furrows around her wrists with abraded contusions but no ligature is present. Fresh tire impressions are found in the mud approximately 20 yards from where the body is located.
Therefore the offender in this particular offense bound the victim to restrain her while she was still alive indicated by the abrasions around the wrists associated with struggling. Our offender removed the ligature before disposing of the body, indicated by the fact that we didn't find it at the scene. The victim was likely asphyxiated with a material ligature about the neck, indicated by the pattern compression and the petechiae. The location where the body was found is a disposal site and not the actual location of the offense indicated by the fact that no blood was present at this location. The offender has a vehicle consistent with the tire impressions and is mobile. All of these details together indicate a competent, intelligent offender whom is likely able to sustain employment, and is very likely a sexual sadist. This is deductively suggested by the vehicle, the use of a secondary scene to dispose of the body to avoid transfer evidence, the removal of the victim's genitals, and the deliberate cutting to the victim's nipples intended to cause pain but not seriously injure.
