Every crime scene in Crime Scene Investigation tells a story, different from other scenes. The crime scene is always thoroughly investigated. One of the many reasons for this is that the crime scene and the victim show some important attributes about the way the crime was committed. This is especially true in case of homicide cases in which murderers have some kind of a pattern. Guessing the pattern is entirely up to the team carrying out the CSI Crime Scene Investigation. Criminal profiling is a popular and widely successful technique employed by Crime Scene Investigators.
The clues left behind by the criminal at the crime scene offer important insight into the crime and somewhat into the psyche of the criminal. It also goes for the way the crime is committed. In homicide cases, while all cases have murder as highlight, each of these murders is committed differently and hence, representing different criminals and different motivations behind the crime. The process of criminal profiling basically employs psychology by applying them to criminals, understanding their motives and then catching those criminals.
When it comes to criminal profiling through crime scene analysis, there are two aspects of great significance. One is the layout of the crime scene and the physical evidence left behind. The other is the way the crime was staged, that is, the way the murder was executed. These are the factors that offer the Crime Scene Investigator insight into the workings of the criminal’s minds. In case of serial killers, there are some patterns that are identifiable such that the crime can be linked to a specific criminal. This becomes possible by comparing the crime scenes, what was left behind, the way the crime was stages and the way the victim was left after the murder. In the crimes of a serial killer, commonalities can be found in these.
By combining the data from the crime scene and that from the autopsy report, Crime Scene Investigators along with expert forensic psychologists can come up with a criminal profile. In making this profile, some of the questions of interest to the forensic psychologist include the way the killer had access to victim, what the attraction of the victim was to the killer, how the criminal killed the victim, and how well the killer covered the tracks or traces of the crime. Answering these questions can allow the CSI Crime Scene Investigation team and the forensic psychologist to come up with answers regarding the motives of the criminal. In addition, through the profiling technique, the forensic psychologist can also make a guess about what kind of fantasies of the criminal are being fulfilled upon committing the crime.
Other than all these aspects, the profilers gain an outlook into the mind of the criminal and how it functions. Studying the victims of the same killer is another important activity. This is done in order to find what’s common in all the victims. Chances are that the very commonality of these victims is what is attracting the killer to them. In studying the victim ology, crime scene evidence collected by Crime Scene Technicians and photos captured by Crime Scene Photographer provide valuable record to all the crime scenes and the victims. Studying the victims has another advantage. Profilers can guess some of the attributes of any future victims that may fall prey to the criminal’s brutality.
Looking into the way the criminal carries out and executes the act of killing is one of the most important aspects of criminal profiling. The Modus Operandi of the criminal includes the tools used for killing, the way the victim is treated before and after death. These aspects will give the profiler and Crime Scene Investigator an insight into the personality of the suspect. This includes any mental conditions or physical conditions that the suspect may have.
According to the profiles created by Forensic psychologists, there are three different kinds of offenders. There is the organized offender who is meticulous and plans the crime. This offender brings the tools for killing and then takes them away. The crime scene of such a criminal is devoid of any tools. Such a crime scene is not full of physical evidence. An organized offender also disposes off the body or hides it. He does everything to cover his tracks and not leave any evidence behind.
The crime scene where a disorganized offender has killed is going to be messy. The killing is done with any tool that first comes into sight at the scene. Such an offender mostly has a history of suffering from mental illness. Such a crime scene reeks of evidence collected at the crime scene because of the killing done in a disorganized haphazard manner. The victim of this offender suffers extensive violence, which shows on the body.
The third kind of offender is the mixed offender. Such an offender possesses a combination of characteristics of 1st and 2nd type of offenders. The crime scene and victim of such offender portray signs of lack of control and urges and fantasies rooted in deep.
Following criminal profiling, suspects can be narrowed down and called in for interrogation, hence progressing in Crime Scene Investigation.
