Describe what duty a law enforcement investigator has to share information with forensic specialists and psychological profiling.

In line with Forensic Specialist the law enforcement investigator will share scientific findings and procedures of the case being handled. It deals with interpreting the scene evidence, interpret and prove how the crime committed and who did it and who are involved in the crime. Forensic Specialist also coordinate and work with the law enforcers, investigators, police, medical, government line agency, and other possible institutions that could help and contribute in resolving the crime. It will also deal with laboratory findings regarding physical evidence, visit and work in the crime scene, conduct investigation, analyze, interpret findings and tries to prove it.

According to FabJob.com Forensic specialists may test for levels of poison, or use the principles of mathematics and engineering to interpret crime scene events. They gather fingerprint evidence and collect DNA samples from crime scenes to see how they match up with databases. As a forensic specialist you will do some or all of the following (http://career.torotosum.jobboom.com/careerpalnning):

·        Visit crime scenes to gather and preserve evidence for analysis

·        Work in a lab analyzing evidence

·        Catalog evidence using a computer database

·        Theorize about what happened at a crime scene

·        Work in tandem with law enforcement officers

·        Appear in court to give evidence

This area of investigation involves deeply on scientific findings based on actual evidence gathered and analyzed and post investigation process of the crime happened.

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.
