Answer: Role and importance of Investigator in crime scene investigation, Forensic Investigator in Crime scene investigation plays a very important role in crime scene investigation, whenever there is a crime first the Police officer reaches the scene of crime and investigate the case and as on requirement the various subspecialties related to that offence concerned Forensic Investigator is called upon to the scene of crime to investigate the case and scene. The goals and objectives of the Crime Scene Investigators at the scene of crime is to collection, preservation, packaging, transportation, and documentation related with physical evidence left behind at the crime scene so as to reach the case to its conclusion. The crime scene is being
Number of suspects can be narrowed and finally solve the cases by analyzing the crime scene features. Muller (2000) describes the information which the criminal profile uses is often taken from the scene of crime, profilers will take into consideration with
These profiles fall between psychology and law enforcement, some call it “investigative psychology” while another refers to it as “crime action profiling”. The main connection, the common goal they all share; help investigators examine evidence, narrow down a suspect pool, or give helpful tips on how to interrogate a suspect already in custody. Psychology is used to investigate behavioral patterns, personality traits, and psychopathologies. Demographic variables including age, race, and geographical locations are also used in the profiles. Recently criminologists, law enforcement officials, and psychologists have all teamed together to take criminal profiling, which started out as an art and transform it into a reliable science.
Who Are They? A Forensic science technician is a person that aids criminal investigators by reviewing crime scenes. They collect evidence from a scene and process it to figure out what led up to cause it. With said evidence, they can reconstruct crime scenes to help push a case further and, hopefully, solve them. However, not all forensic scientists are the same.
Criminal Investigative Analysis, also known as criminal (offender) profiling, is an investigative tool which is used within the law enforcement community to help solve violent crimes. According to Canter (2005), an investigative psychology describes a framework that integrates several range of aspects in to all contexts of criminal and civil investigation.The analysis is based on a review of evidence from the crime scene and from witnesses and victims. The analysis is done from both an investigative and a behavioural perspective. The contributions that psychologists can make to police investigations are most widely known and understood as this offender profiling. Offender profiling, as typically practised, is the process by which individuals,
One of the reasons why criminal profiling can be useful in criminal investigations is that it helps investigators to apprehend the suspect without having to waste time. Since psychological and behavioral patterns can be traced, the suspect list can be narrowed, making the whole investigation process much shorter and simpler. A psychological picture can be formed by the profiler showing the type of offenders. Formation of profiles can direct and lead the whole investigation in finding the suspect by providing the investigators with the required information. This mainly works for large crimes like serial killings, serial rapes, arson and so on.
Gottfredson and Hirschi (1990) acknowledged within their self-control theory that the opportunities for crime are readily accessible and crime is typically not difficult to perform. Yet, Gottfredson and Hirshi focused on the lack of self-control as the cause of crime rather than the opportunities for crime. Cohen and Felson (1979) in describing the routine activity theory, later stated that motivated offenders must find suitable targets that lack guardians in order for crime to occur. Situational crime prevention strategies were the first to focus on specific crimes, the environment and the reduction of crime opportunities. The situational crime prevention theory originated in the Home Office Research Unit of the British Government in the 1970’s (Clarke, 2018).
They make sure all the evidence is packaged correctly to be sent to a forensic laboratory. Being a Crime Scene Investigator requires specific education and training. Having a four year degree is common for crime scene investigators. Post-graduate work and master’s programs are also often pursued by crime scene investigators as to achieve crime Scene Investigation jobs that require specialized knowledge, such as DNA (DeoxyRiboNucleic Acid), latent print, and firearms (“CSI Job Description”). The job description may vary for a crime scene investigation depending on the geographic location, size of the law enforcement agency, or the size and scope of the crime scene.
On the other hand, system variables are controlled by people within the criminal justice system when collecting information from eyewitnesses. In this case, errors are preventable. I will be discussing three estimator variables and three system variables and
This is because it is applied as police carry out their daily routine activities such as preventing crimes, searching, arresting and charging suspects. Given the ambiguous nature of the existing criminal laws concerning the scope and dealings of conflict and disorder situations, alongside the limited resources allocated to the police departments, and variations in nature of offences; police discretion becomes a principle part for officers to give weight to law enforcement (Griffiths, 2013: 122). First of all, individual officers in streets and fast areas has to decide whether an incident they are coming across fits into the definition of an offence as stipulated by the law and to what extend are they to be subjected to judgement. For instance, in a case of an assault, the law does not give further definitions on whether it is simple or aggravated assault. So it is the mandate of the officer to what kind it fits
