There are also specific photographs that need to be taken at the crime scene to ensure a couple different things. One that the crime scene can be reconstructed and two that the crimes can be linked back to a suspect. Once this has been done it is important to know if the computer is on a linked network or not and whether you should shut down the computer. There are also certain circumstances that make forensic evidence inadmissible in court and this is important to know so that procedure is followed to ensure all evidence will stick to a suspect. When it comes to a crime scene investigator there are certain things they can and can not do in regards to a body at the crime scene.
The crime scene technician must interview the first officer at the scene or the victim to ascertain the "theory" of the case. Basically what allegedly happened, what crime took place, and how was the crime committed. This information may not be factual information but it will give the crime scene technician a base from which to start. Examine the crime scene as the second step in the protocol. Examine the scene for what?
Official statistics is the name given to the numbers of crimes reported to or unveiled by the police themselves, which lead to a conviction, caution or are dealt with in some formal way by the law. Only offences which are dealt with by one of the above are actually recorded in official statistics. These offences can vary from minor incidents such as a window being broken to, an offence of a more serious nature such as rape or murder. These are social problems that are constructed by society, something that goes against the 'normal' runnings of society. The statistics can give us an understanding as to the levels of these crimes and as to why or where they are most likely to occur.
Holmes & Holmes (2009, p290) stated “To appraise a crime without some knowledge of the victim is certainly remiss.” The victim constitutes half of the crime therefore victimology should be heavily looked at in order to connect them to the offender (Douglas, Burgess, Burgess, & Ressler, 1992).Victimology is important to an investigation process in that, it is not just learning about the victim’s personal history and personality, but it also why the victim was chosen (Petherick, 2010). Holmes and Holmes (2009,p 291) created a list of elements which should be important to victim profiling it includes: "Physical traits, marital status, personal lifestyle, occupation, education, personal demographics, medical history, psychosexual history, court history, and last activities." A victim’s lifestyle, preferences, family, relationships, and routines, can give investigators clues about potential suspects who had access to the victim (Brown & Davenport, 2012). Other concepts that should be considered when victim profiling are the method of approach, method of attack and risk assessment (Turvey, 1999). Con, surprise, and blitz are three methods of approach that an offender will use to capture his victim.
Crime Scene Investigation CRJ 320 Crime Scene Investigation One of the most important aspects of being trained in Law Enforcement is the ability to conduct a crime scene investigation. The ability to contain and not contaminate the crime scene while also gathering information is a daunting task for any individual. Taking steps to insure the scene is secure, wounded are cared for and that evidence remains intact are just a few of the necessary tasks. Attorney General Janet Reno once stated that “Actions taken in these first few hours of investigation at a crime scene can play a pivotal role in the resolution of a case. Careful, thorough investigation is key to ensuring+ the potential physical evidence is not tainted or destroyed or potential witnesses overlooked.
Senior Capstone in Criminal Justice: CRJS400-1303B-02 Unit 2 Group Project Individual Portion Margaret Burnett Pro. Ferguson Tire Tread Analysis Unknown tire tracks are pretty much treated the same way as footwear impressions when found at a crime scene. But, the focal point is to preserve any impressions to be later examined by forensic experts. Before they are moved or handled at a crime scene, they have to be photographed, and taken from various angles showing the visible details of the impression and its position in relation to the remainder of the crime scene. These photographs are a backup procedure because they provide a point of comparison only when analyzing the actual preserved impression.
Some were later asked to describe the speed of the cars before they smashed into each other, others were asked the same question, but using the term hit instead of smash. In their responses, those questioned using the term smash were more likely to state that they saw broken glass, though that was false (Born, Colleen 1997). Most often, eyewitnesses are unwilling to reconsider their initial understanding once they state facts in a particular way or identify a particular individual as the perpetrator of a crime. This is basically due to memory reconstruction. In a study conducted by Barbara Tversky and Elizabeth Marsh on the vulnerability of human memory to bias, showed that participants recalled a story
The investigation consists of many aspects, starting with an inspection of the accident site. Measurements are taken from evidence left at the scene, such as skid marks, point of impact, gouge marks, and final resting position. These measurements are then used to create a diagram to reconstruct the accident. The police will also do individual vehicle inspections to check things like amount of damage along with inspecting brakes, tires, steering, and lights to see if they were a causing factor (Glennon, 2001). Once the investigation is complete they can begin to reconstruct the accident.
The criminal profiler creates a psychological profile or picture of a suspect based on what he/she knows about motivation, mental illness, and also human behavior. The best place to begin getting an idea of a criminal's mind is often at the scene of a crime. Investigators pay particular attention to the things done at the scene or to the victim and also to the things not done. These observations can lead to a behavioral profile of the yet unknown suspect. Once the behavioral profile is done, the profiler can then compare this to other criminals or mental patients with the same basic characteristics.
Jasmin Finnie Sep 6, 2010 White Collar Crimes Professor . Kellam When it comes to criminal justice, the term "White Collar Crime" is brought up very often. What exactly is a White Collar Crime?
