Crime Scene Investigation Essays

Forensic Science is the process of finding evidence or material connected to the crime. When a crime is committed, police officers take over and secure the scene so if needed, special investigators can search the area to collect and transport evidence to the crime lab. In addition, forensic scientists work in laboratories, courtrooms, etc. But forensic scientists do not carry a weapon or have the authority to arrest someone, even if proven guilty. They research evidence connected to a crime scene to figure out and uncover who committed the crime. It is often used in cases like airplane crashes, natural disasters, terrorist attacks, crimes committed during the war and cause of sudden death (Funkhouser). Forensic science can

Why is it important to secure the crime scene? What do you think would be the most difficult part of doing this?

This examination is one of the initial steps to enable specialists to sort out a Crime. For instance, where the blood is (showered drops of fluid) or where projectile pieces are found can enable specialists to make sense of how a Crime happened. Crime scene investigation can likewise help reply (more than two, yet not a great deal of) different inquiries regarding the Crime, for example, time of death. It might give (event(s) or object(s) that demonstrate something) that can be utilized as a part of a criminal trial. Although Crime scene examination may begin with the main cops at the scene, extraordinarily prepared Crime scene specialists for the most part process the Crime scene. One of the initial steps is to secure the scene, which implies restricting access to non-critical work force. This keeps the Crime scene from getting to be plainly tainted. Examiners may than stroll through the Crime scene, to get a general picture of what happened. This is only a rundown, with significantly more depicted/clarified investigation happening. Photographs are frequently taken and examiners take notes on subtle elements of the Crime scene, for example,

A Crime Scene Investigator, also called a Forensic Scientist, supports polices detectives and other law enforcement investigative teams. They help by locating, collecting, and processing evidence, such as evidence tagging, sketching, photographing and print gathering for laboratory processing. They also preform and document autopsies and describe the levels of decomposition and other post-mortem procedural steps. They write reports that can be used as evidence, and investigators could testify as a witness.

For the lecture on Crime Scene Investigation and Criminal Investigation we were assigned a cold case reading. This cold case reading entitled “Cold Case Models for Evaluating Unresolved Homicides” written by James Adcock PhD and Sarah Stein PhD outlines cold cases and their nature as well as providing possible protocol for cold case scenarios. Within these cold cases, the main goal is to ultimately solve the investigation. However, it is never that simple. Where Crime Scene and Criminal Investigators come into play is in the fact that they are involved with any ongoing investigation; whether it be a cold case or hot one. In most cases these two positions are equally important, these two work hand in hand to paint the entire picture of the crime that took place and the criminal that is to be apprehended. Cold case investigations are similar and different at the same time to any standard investigation. The main difference rests in the fact that these cases have been unsolved for so long and therefore, the dynamic of the investigation must change.

A CSI will collect the evidence, documenting everything to help convict the criminal, while a forensic scientist will analyze the evidence that a CSI bring to them. A crime scene investigation is the meeting point of science, logic and law. "Processing a crime scene" is a long, tedious process that involves purposeful documentation of the conditions at a scene and the collection of any physical evidence that could possibly illuminate what happened and to point to who did it (3). There are no typical crime scene, so there is not typical investigation process. Many CSI will approach a crime scene from all different angles because what they see and what someone else see may be different, since one cannot view

Then the lead officer will need to determine the boundaries of the scene starting at the central point and extending outward, safeguarding the crime scene with yellow police tape noting possible paths of entry and exits of suspects and witnesses. It's better to close off a larger area at first and then make smaller if needed. The precautions that are taken are very important to safeguarding evidence and minimizing contamination.

From day to day it may be different but typical the homicide detective will be called to a investigation scene. First off when you get to the scene I will assess and manage the scene. This means examining the victim for clues. Next I will document the scene I would complete a walk through, making sure I do not disturb any evidence. Also making permanent record of the scene, it is important to do this before moving anything. After that I will photography or videotape the scene conducting a thorough search; make a rough sketch; dust for fingerprints; identify, document, and collect all fluids and fibers: and control evidence to maintain its integrity. Then canvass the area to locate witnesses. This step is critical because more homicides are solved by canvassing than any other method. Finally identify suspects, proper handling suspects leads to a successful prosecution. But remember that all suspects are still entitled to their rights C. The excitement of going to work each day and not knowing what is in store for you is very interesting. This job may be asking a lot even in an investigation but the adrenaline is very

What is crime scene investigation? Crime scene investigation is the use of physical evidence at the scene of the crime and the use of of the deductive and inductive reasoning to gain knowledge of the events and of the surrounding crime. Crime scene investigating is a big combination of Science, logic and law.

While entering the crime scene, the first responding officer should look out for any evidence which is present on the ground. There have some cases in which the first responding officer stepped on the evidence such as blood or

to see if the suspect is anywhere around then they checked to determine the two

The purpose of crime scene reconstruction is to help determine what actually occurred or eliminating actions, events, or suspects through a methodical analysis of identification and examination of physical evidence. By recognizing and identifying the location, impressions, patterns and positions of physical evidence, as well as the scene presentation, an examiner or investigator can apply scientific methods, logic and past experiences to develop a theory in conjunction with information collected from a victim and witnesses (University of Split, n.d.).

Crime scene preservation should be the most important step to any first responder. This protocol should continue to be followed by anyone who processes the scene. From the moment the first responder arrives at the scene, he/she should exercise a pertinacious attitude to insure that curious onlookers and personnel who are not involved in a task related to the scene, remain outside the cordoned

Crimes are committed every day. Ranging from small crimes like theft to major crimes like murder. In “Forensic science: Evidence, Clues and Investigation” by Andrea Campbell. You will learn about forensic science and how it is used.

The photographer that is present at the crime scene is responsible for making one picture worth a thousand words. Photography plays an integral role in the documentation of physical evidence found at crime and accident scenes as well as during forensic autopsies. Forensic Photographers are among the first crime scene technicians to arrive at crime and accident scenes. They walk through a scene to obtain an overview before they begin taking photographs. Forensic Photographers apply their technical skills and their knowledge of anatomy and forensic requirements to take photographs that convey the information that crime scene, criminal, medico legal, or forensic investigators need documented. These
