Have you ever wondered how police officers know who to arrest for a crime? Well in order to catch criminals, evidence and witnesses must be gathered. Those who perform these tasks are known as detectives. Detectives are also known as criminal investigators. I have always liked solving mysteries and, that is exactly what detectives or criminal investigators do.
In addition, a detective questions victims, witnesses, and suspects. They record all statements and observations in their notes. All aspects of the preliminary investigation are done to preserve the crime scene, and there is an attempt to determine the time that the crime was committed and the mod-us operandi. Detectives realize that a criminal always makes mistakes, and leaves some type of evidence behind. Most times the evidence left behind is less visible, such as fingerprints, blood stains, and small particles.
Criminal profilers study every behavioral aspect and the details of unsolved crimes in which certain evidence has been left at the scene. FBI profilers often solve murders by observing the offender's behavior. By examining this the profiler can identify as a physical, erotic, verbal and interactions they had with the victims. Crimes are often solved by the offender’s psychopathology. Crimes that FBI profilers might be acquainted include sexual assaults, homicides, kidnappings, bombings, threats, battery, and manslaughter are just some of the main points of what FBI profilers deal with on a normal basis.
Being a criminal profiler is a tough job but with hard work and dedication it is a great career choice. A criminal profiler gives a description of what they think the suspect looks like and acts like. They do this by examining the scenes of where the victims were murdered and looking for clues on why the suspect did it, how they did it, what kinds of victims are being targeted, and why they chose a certain location. They find all this out by using evidence from the nature and surroundings of the crime scene (Wachtel). By doing all of this they may be able to find a motive on why the suspect did this.
Andreana Bowins Forensic Science Technicians “It is a forensic science technician’s job to help investigate crimes by collecting and analyzing physical evidence. Forensic science technicians may either be generalists who perform all or many of the duties listed above, or they may specialize in certain techniques and sciences. Generalist forensic science technicians, sometimes called criminalists, perform the duties of crime scene investigators and laboratory analysts. They collect evidence at the scene of a crime and perform scientific and technical analysis in laboratories or offices.” (BLS.2012). “At crime scenes, forensic science technicians analyze crime scenes to determine what and how evidence should be collected, take photographs of
The suspects then enter the criminal justice system where they are tried using the evidence collected at the crime scene. Forensic investigations require skills of specially trained scientists, police, engineers, doctors and others. “These investigators observe all types of evidence, from weapons to bloodstains and from computers to bugs” (Erzinclioglu 5). The greater the evidence against a person, the greater the chance of conviction. Homicide detectives usually work in pairs and approach a crime scene with five basic questions: Did the death take place at the crime scene or elsewhere?
They are the initial result in clearing out most crimes, why? Since they are the first to arrive at the crime scene, the officer’s conduct a preliminary investigation. This includes “in determining whether the offender is at the crime scene or in the area, responding to the victim’s needs, and ensuring the general safety of anyone in the immediate vicinity” (Grant and Terry). The initial crime scene processing and the recordings of relevant evidence and information are critical for a patrol officer to document, since the report will pass on to the detectives/investigators (Grant and Terry). According to Osterburg, an investigation is a reconstruction of the past (5); it gives... ... middle of paper ... ...on and its connection to evidence are seen through TV shows, but the procedure an investigation goes through and its guideline are not shown.
Forensic tech work primarily for local governments and state in police departments, coroner offices, and crime laboratories. This field is a combination of lab and field work the best of both worlds (Career guide for forensic science technician (n.d). This is what makes Forensic Science Technician the field of interest; the customary duties of a forensic science technician consist of gathering evidence, investigation of evidence collected, and reporting their discoveries in writing and may also be called into a court of law (criminal or civil laws) to present their finding before a judge (Career guide for forensic science technician (n.d).. There are several different areas of expertise in the field of a forensic technicians are often responsible or specialize in particular types of evidence such as biochemistry, ballistics, fingerprinting, and handwriting analysis. It has been said that forensic science technicians are mostly call upon to assist in two places on crime scenes and in crime labs (Dillon .H, 1999).
Investigators must always keep in mind the fact that normal human behavior, traits, and patterns usually remain consistent, regardless of the activity being performed. Whether a serial killer knows it or not, every murder they commit, they leave their distinguishable mark in some way or another, and that is the key lead that criminal profilers use to catch the correct person (Munn and Douglas Violent Crime Scene Analysis: Modus Operandi, Signature, and Staging 1). Criminal profiling is an effective way to identify and find a criminal. The term “serial” applied to the word murder or killer can raise problems and questions. Serial implies that several murders have taken place at different times.
A Crime Scene Investigator must first approach the crime scene as if it is their only opportunity to protect and retrieve physical evidence. There are special technics and tools that crime scene investigators use to retrieve, preserve, and label all types of evidence (for lists of Crime Scene Equipment see Appendix A). The general protocol for crime scene investigation, processing, and analysis involves five basic steps: interview, examine, photograph, sketch and process (Berg, 2008). When looking at the crime scene it needs to be looked at with fresh eyes and without a prejudiced opinion of what happened, how it happened, or who might have done it. A conclusion may be based solely on the evidence and so an investigators integrity and judgment, gathering the evidence, maybe what stands between a conviction and a dis... ... middle of paper ... ...
