While in the area of Psychological Profiling it provides specific way of guiding the direction of the investigation although it cannot supply concrete evidence during the process of investigation. This area also deals mostly on the behavior, motives and background of the offenders to further lead the investigation process.
This method was discovered in 1950’s in America. Later it was discovered through research that intriguing patterns of behavior leading to a serial killer. Based on forensic science some of the patterns discovered include the killers having suffered from child abuse as youngsters, whether it is sexual or physical and that this kind of abuse led to abnormal behaviors later on. As children and teenagers, they started fires, were cruel to animals or children and then in the late teenage years to early twenties, were engaging in petty crime and defying authority.
Two approaches had been used in using psychological profiling one is the induction which involves assuming that when a criminal commits a crime, he or she will have a similar background and motive to others who have committed a similar crime. While deductive involves a process that avoids generalizations and averages. This method involves intently studying suspects in extreme detail and adapting findings in which new evidence surfaces. A deductive profile is set up based on the offender's actions before, during and after committing the crime (http://library.thinkquest.org/04oct/00206/nts_psychological_profiling.htm).
On this process psychological profiling is much applicable to the serial type of crime which is called “serial killer”. But somehow there are instances that these two methods or process of investigation would somehow applicable to a certain crime.
