THE CRIME SCENE PROCEDURE
One of the most important parts of crime solving is to identify all of the unknown victims, if they are unknown. When police have enough evidence they check the National Crime Information Center for possible victims (Jackson #). Part of this evidence they find might be the victim's body; when police find a body the first thing they do is have it sent to the lab to have an autopsy (Owen #). When the body is older and only has left-over bones, the first thing the forensic anthropologist will do when they are looking at the skeleton is identify if they are human—this is because human bones look very similar to, and may be mistaken as animal bones. After the forensic anthropologists receive bones; they have to use what

An autopsy or postmortem is an after death examination. This is conducted by a forensic pathologist looking for signs of injury (Cooper #). First, firearm examiners examine ammunition components through a microscope to see if they can be pinned to specific weapon (Jackson #). Because of the imperfections of every gun, bullets have a set of marks left imprinted in them that no other gun can produce (Owen #). Another weapon the murderer may have used is poison the types of poison are usually different when committing suicide when compared to a murder. Acontine, Aropine, Strychnine, Thallium, Arsenic, Cyanide, fungi poisons, and Ricin are all common poisons used by murderers. Poison from the victim’s death shows up in the blood, urine, and tissue samples taken during an autopsy. Knives and hammers are often used in murders, these weapons are used to produce blows to the victim that show up usually during the examination of the head (Owen …show more content…
Forensic Pathologists complete the autopsy by examining the body and sending in biological materials such as: hair, threads, fingernail scrapings, blood samples, and urine samples (Jackson #). After the body is washed the hair sample is removed from the body and it is stored for examination. Other bodily fluids that are removed during an autopsy are cerebrospinal fluid and stomach contents which are taken set aside for later tests. Determining the cause of death requires pathologists to look at wounds such as close range gunshot wounds that have burning around the edges, and sometimes fibers from the criminal’s or victim’s clothing (Owen #). Once the pathologist has completed their part of the autopsy, forensic toxicologists make an examination and determine if any chemicals were involved in the victim’s death. Finally the body is given back to the forensic pathologist who determines the cause of death after thoroughly examining the body (Jackson

    Most remains depart for burial within a few days. For the rest, it gets complicated. The easiest resolution is furnished by fingerprints; otherwise by dental and medical records or, as a last resort, by DNA. The medical examiner can also do a so-called contextual ID; when all elements are considered, none of which by themselves bring certainty, a sort of circumstantial identification can be…

    The BTK was a very good but sloppy serial killer and it’s only because the lack of modern forensic technology that he was able to kill so many people. He knew not to leave finger prints but left DNA at almost every crime scene. DNA testing in the 1980s was relatively new and took a large sample to create a DNA profile and unlike today where the tests can be done within a day, there weren’t as many crime labs that could process the DNA. The Crime Scene investigators had a lot of evidence to process because the killing spread across the entire house.…

    The study of forensic sciences is a huge part in applied anthropology as the anthropologist will use the facts they know to figure out the facts of the bones. In the video “FAFG English” the narrator says “Today in the 21st century, the scientists can make the bones speak” (1:03-1:08). This statement shows us how important the discovery of remains is to these scientists as they can tell everything about the past by the remains of a human. Discovering the remains of a human and figuring out who that person is, how that person died, when that person died, and who the person was connected to is applying academic anthropology to fill in the missing knowledge. Being able to tell a person exactly how their loved one died is what these anthropologists are all about as it helps people with the grieving process.…

    To help make the case go along smooth they will need to pay immense attention to the crime scene. They cannot compromise the crime scene; they will need to look over everything twice or more, just to make sure them and their team didn’t miss anything (“Coroners”). Determining the blood splatter, post mortem “before death” and antemortem “after death” injuries will help in the discovery of the killer (“Coroners”). Getting glasses to see things better will be a great idea to…

    About 300 feet away from the football field at the University of Tennessee, lay the offices of many forensic anthropologists. These anthropologists study dead bodies at the Body Farm. Dr. William Bass established the Body Farm in 1987 in order to research the decomposition of human remains. Human decomposition (HD) has helped in many forensic investigation cases to help determine cause of death and most importantly Time of Death (TOD). The interest in HD research has increased over the years since Dr. Bass established the Body Farm and many law enforcement agencies, including the Federal Bureau of Investigation (FBI), have used the Bass research to aid in criminal investigations; utilizing every aspect of the growing field.…

    While x-rays are regarded as accommodating tools to complement forensic investigations, there are also limitations present. CT imaging provides optimal views of anatomical structures with elaborate reconstructions to view the images in innumerable ways. The remarkable features of CT scanners are associated with expensive costs of the construction and maintenance of the scanner. Though the payoff is extraordinary, facilities would need a great amount of funding before the installation of a CT scanner takes place. Post mortem CT scanning is limited by the absence of intravenous contrast techniques to the study as the cadaver lacks the circulation needed to highlight vascular structures.…

    The first thing I would do in processing the crime scene is interview the first officer that arrived at the crime scene to establish a theory of the case. Second I would examine the crime scene to see if the theory of the case is substantiated by what I observed. During this time I would start identifying possible items of evidence, identifying entry and exit points and getting a general outline of the homicide scene. Third, I would take some pictures. Photographing the scene would allow me to record a pictorial view of what the scene looked like undisturbed and to record items that is possible evidence.…
