Douglas and his colleagues faced transformed the field, shaping it into what we know as modern-day criminal profiling. Find out the role Douglas played, some of the different ways you can become a criminal profiler , and what the job entails. John E. Douglas and his partner Robert Ressler were supervisory FBI agents who interviewed incarcerated serial killers with the hope of obtaining detailed information on crimes to better understand motives and to create a centralized database of serial offenders in the nation.
Detailed crime scene information like this could match serial killers to their crimes across states, making it easier to arrest offenders and share data with law enforcement. The s saw a rise of serial crimes across the US, and specialists set out to stop the rising tide of violence. Between the years and , Douglas, Ressler, and their colleagues interviewed 36 serial killers and collected a well of information. Then, they set out to create the database that would allow open case information and behavioral characteristics or patterns to be cross-referenced nationwide, called the Violent Criminal Apprehension Program ViCAP.
Using ViCAP, investigators could finally search for an unknown subject and match case details to those from other open or closed cases to find patterns. Police officers in the US or Canada can now submit a request to the NCAVC if they have a series of unsolved murders, suspicious cases, or unidentified bodies, and the ViCAP computer software runs through the if-then scenarios a human profiler would be based on the idea that behavior reflects personality.
Although the criminal profiling field was not officially founded by Douglas, he did give us a quicker way to profile criminals nationwide. Without his ability to gain the trust of some of the most notorious serial killers Charles Manson and Ted Bundy, for example , this untapped knowledge and insight may have gone unnoticed. He would mutilate their abdomens after killing them and would then slit their throats.
The then police surgeon, Thomas Bond, was finally asked to examine the case and give his inferences. He studied the case of the most mutilated victim and the post mortem notes of the past canonical murders.
The profile indicated that the murderer must be a physically strong man who was quite cool and daring. He was believed to be prone to periodic attacks of erotic and homicidal mania. Additionally, Bond could also conclude that the murderer may be suffering from an abnormal sexual condition similar to Satyriasis. The process of profiling started when forensically-inclined psychologists and psychiatrists interested in understanding the criminal mind started publishing psychological profiling and criminal case-study descriptions.
This was usually aimed at analyzing the psyche of individuals for strategic gains, such as the psychological assessment of Adolf Hitler during World War II. Early profiling assessments were mostly distributed to mental-health professionals for the purpose of research and theoretical discussions. Some say that the first modern-day application of criminal profiling was done by Dr.
James A. Brussel, a New York-based psychiatrist, in the s. Being totally frustrated with their vain attempts to capture Metesky, the police finally resorted to taking Dr. On examining the crime scene photos and the notes left by the bomber, Dr. Brussels could draw some ground-breaking inferences. He was able to deduce that the bomber was in his 50s, was unmarried, self-educated, foreign-born, paranoid, and was staying in Connecticut with his sibling!
He used a combination of logical reasoning and psychology to gain these insights. For instance, he was able to deduce the approximate age of the bomber knowing that paranoia tends to peak when an individual is around Thus, 16 years after the first incident, the bomber was likely to be in his 50s. When in , Metesky was finally located and arrested by the police, most of Dr.
Even his uncanny prediction that Metesky would be wearing a buttoned double-breasted suit when the police locate him was spot-on!!! A criminal profiler is adept at identifying suspects by analyzing the mental, psychological and emotional characteristics of an individual. Behavioral consistency is often used to link a crime having little evidence, to a particular suspect by analyzing the similarities with past incidents.
Homology forms the foundation of the idea that similar crimes are committed by similar criminals who possess common characteristics. So what do forensic experts do when there are no eyewitnesses or forensic evidence? That is when forensic profiling comes into the application. Linkage analysis is one of the profiling techniques used for offender profiling. Gerard N. Labuschagne has defined this profiling technique as a method of behavioral analysis to evaluate the possibility of a series of crimes as being associated with one offender.
It has often played a crucial role in the trial of serial offenders. This helps determine his modus operandi. Additionally, it also examines the routine and fantasy-based behaviors and the unique resemblances in each incident as exhibited by the offender. Criminal profiling techniques are based on 4 main approaches — geographical, clinical profiling, investigative psychology and typological. Thus, criminal profiling techniques involve an in-depth analysis of the crime scene and finding common patterns with previous incidents.
Eventually, criminal profilers are able to draw some conclusions on the possible motives of the crime. However, one must not confuse criminal profiling as a tool that helps identify the specific offender linked to a crime. Psychology, Public Policy and Law, — Douglas , J. Douglas, J.

Concerns The methodological concerns about bias in these studies, and the relatively small sample sizes in some research should be considered. Contradictory In conclusion, much of the literature in the area is contradictory, which in its own way is a positive and healthy way for the discipline and the methods used in evaluating it to develop and evolve.
