The Use of Criminal Profiling in Criminal Investigation
1. Introduction
In the discipline of criminal profiling, the term signature is used in the description of the distinctive conduct committed by a lawbreaker. This term was first used by John Douglas in his work on offender profiling. Douglas’ term is different from John Money’s concept of a probative linkage, which is defined as “any relationship between two or more items of evidence which makes it more probable that a particular proposition is true than if the relationship did not exist” (Money, 1993, p. 4). In contrast, Douglas’ signature refers to those aspects of an offense that are unique to the offender and not essential to the commission of the crime (Douglas, 1980).
The use of criminal profiling in criminal investigation can be traced back to the late 19th century, when police in New York City began using psychological techniques to profile criminals. These early efforts were largely unsuccessful, but they laid the groundwork for modern criminal profiling methods.
In the 1970s, the Federal Bureau of Investigation (FBI) established a unit to develop and apply behavioral science techniques to crimes. The unit was led by John Douglas, who is widely considered to be the father of modern criminal profiling. Douglas and his team developed a method for analyzing crimes based on the assumption that criminals reveal their personality and motives through their actions.
This approach has been criticized by some psychologists who argue that it is based on unsupported assumptions about human behavior. However, criminal profiling has been used successfully in a number of investigations, and it continues to be an important tool in law enforcement.
2. What is criminal profiling?
Criminal profiling is a method of identifying unknown offenders by analyzing their crimes and comparing them to known offenders. The goal of criminal profiling is to narrow down the pool of potential suspects so that investigators can focus their efforts on those who are more likely to be responsible for the crime.
Criminal profilers use both qualitative and quantitative methods to analyze crimes. Qualitative methods involve interviews with witnesses and victims, analysis of crime scene evidence, and offender Behavior analysis–Burglary-Offender Profiling System (BOBOSS)>. Quantitative methods involve statistical analysis of data from large numbers of crimes.
The most important factor in any criminal profile is the type of crime committed. Different types of crimes require different types of profiles. For example, homicides are typically divided into three categories: organized, disorganized, and mixed. Each category requires a different type of profile.
Organized homicides are typically committed by offenders who are calm and controlled. They plan their crimes carefully and take measures to avoid detection. Disorganized homicides are typically committed by offenders who act impulsively and lack planning or forethought. Mixed homicides are committed by offenders who display both organized and disorganized behaviors.
In addition to the type of crime committed, other factors that must be considered when developing a profile include the victimology, geographical location, time period, modus operandi ( MO), and forensic evidence left at the crime scene. All of these factors can provide valuable clues about an offender’s identity and motivation.
3. The use of criminal profiling in criminal investigation
The use of criminal profiling in criminal investigation can be traced back to 1886, when New York City police detective Thomas Byrnes published Professional Criminals of America, a book that included profiles of more than 600 known criminals.
Byrnes’ work was based on the psychological principle of association, which posits that people tend to associate with others who are like them. Byrnes applied this principle to criminal behavior, arguing that criminals are more likely to associate with other criminals. Based on this reasoning, he developed a method for classifying criminals based on their physical appearance, biographical information, and criminal history.
Byrnes’ work was largely unsuccessful, but it laid the groundwork for modern criminal profiling methods. In the 1970s, the FBI established a unit to develop and apply behavioral science techniques to crimes. The unit was led by John Douglas, who is widely considered to be the father of modern criminal profiling.
Douglas and his team developed a method for analyzing crimes based on the assumption that criminals reveal their personality and motives through their actions. This approach has been criticized by some psychologists who argue that it is based on unsupported assumptions about human behavior. However, criminal profiling has been used successfully in a number of investigations, and it continues to be an important tool in law enforcement.
4. The advantages and disadvantages of criminal profiling
Criminal profiling can be a valuable tool in criminal investigation, but it also has its limitations. One of the main advantages of criminal profiles is that they can help investigators focus their efforts on suspects who are more likely to be responsible for the crime. In addition, profiles can provide valuable insights into an offender’s personality and motivation.
However, criminal profiles are not always accurate, and they can sometimes lead investigators down the wrong path. In addition, developing a profile can be time-consuming and expensive. For these reasons, criminal profiling is often used as a last resort when other investigative methods have failed.
5. The different types of criminal profiling
There are three main types of criminal profiles: geographical, psychological, and sociological. Geographical profiles are based on the location of the crime scene and the victim’s body. They are typically used in homicide investigations. Psychological profiles are based on an analysis of the offender’s behavior. They are typically used in sex crimes investigations. Sociological profiles are based on an analysis of the offender’s social background and relationships. They are typically used in organized crime investigations. All three types of profiles have their advantages and disadvantages, and they should be used in combination to maximize their accuracy. For example, if a homicide occurs in a rural area, a geographical profile would be most useful; if the victim was sexually assaulted, a psychological profile would be most useful; if the homicide appears to be related to organized crime, a sociological profile would be most useful.
