The so called physical evidence collected by the crime scene investigator at the crime scene in the form f physical evidence that it May prove that a crime has been committed, they can Establish any key elements of a crime, Link a suspect with a crime scene or a so called victim, Establishing the identity or individuality of a victim or suspect, Corroborate verbal witness testimony and Exonerate the innocent this is the role and importance of crime scene investigator in the crime scene investigation at scene of crime. This evidence collected by the investigator will give the important clues to the investigating authority i.e. police officer to lead the
Because of this, any police officer can be put into the position of first responding officer to a crime scene. This first officer should approach the scene in a slow pace and methodically. But sometimes this may act impractical. The officer may be busy in any other works of the case such as rescuing the victim. But the officer should make mental or written notes about the condition of the scene.
However, investigations have to go beyond brothels, which are the most obvious sites of crime to reach the source of trafficking and to expose trafficking routes, crime syndicates and gangs involved etc. This calls for multi-disciplinary and in-depth approach. Efforts also have to be made to unearth illegal assets of the traffickers and to confiscate and forfeit these
In many countries, an issue of serial killers has always been scrutinized and considered as extremely serious. The United States is not an exception. Recently, a number of serial killers on the US territory has been increasing remarkably (Criminology: The Essentials 2013, 115). There are many traditional methods aimed to identify this criminals such as examination of witnesses, search for suspect with a motive; however, these methods provide a limited success in comparison with other, new and nonconventional, method called ‘criminal profiling’. The criminal profiling is based on the deduction of specific evidentiary patterns, observation of physical evidence, and the extrapolation of those patterns into a detailed description of the behavioral and psychological features of a possible perpetrator.
The boundaries of the crime scene need to be defined and controlled. In other words it is important to establish the perimeter and decide what is inside the crime scene and what is outside the crime scene. It is much better to over define the crime area rather than under define it. Traffic cones, tapes are usually used to define the boundaries or the perimeter. Multilevel containment (Dutelle, 2013) can be used at times.
A crime scene is s place where a crime has occurred and has within its purview, any area where evidence can be found. The use of deductive and inductive reasoning to gain knowledge of the events surrounding the crime. Crime scene investigation is multidisciplinary and involves a systematic search of the crime scene; meticulous observation and documentation of the scene; photography and sketching of the scene; the identification, processing and collection of physical evidence such as fingerprints, footwear impressions, hair, fibers, biological fluids, and materials for DNA analysis; and. perhaps most important, the application of careful
FORENSIC SCIENCE can be defined as the application of science to civil and criminal law. It is a field that is grounded in applied ethics. The identification, collection, and preservation of any piece of forensic evidence will ultimately involve numerous individuals. At any step within the process, evidence can be deliberately or accidentally mishandled. This risk begins at the scene of the crime, where there is the possibility of evidence planting, destruction, or mishandling.
Abstract Reconstruction of crime is very much essential to solve any mystery for police and investigative agencies. Correlation of victim, accused, weapon of offence, scene of crime, human behaviour, environmental evidences etc. are very important for the same. A crime reconstruction must require keen observation, understanding of science, recognition of evidences, and application of critical thinking with logic. Key words Crime, Reconstruction, Scientific method, Evidence, Ethics.
APPLICATIONS CBIR is growing interest in many fields. Application areas of CBIR are as follows: A. Crime Prevention Records of criminals like photograph, fingerprint with other information is maintained by the police and investigating teams. These records are then used for face recognition and fingerprint matching. To identify any person or to find if person is having the criminal record in past or not, these records are very useful and helpful.
The search of the crime scene and its capacity is considered the most significant stage of the investigation. The Investigator should keep in mind that physical evidence is the most credible kind of evidence and according to the Locard Exchange Principle “every contact leaves a trace”. It is because of this reason that the investigator’s obligation is to see to it that the crime scene is instantaneously conserved. Precaution must be taken so that the people within the vicinity of the crime scene do not contaminate the scene by leaving footprints or fingerprints or by disturbing the crime scene. Prior to the walk-through, the investigator must stop and scrutinize the area as a whole, making notes of everything possible before going into the actual crime scene to conduct a more detailed assessment.
