Questioned document examiners also determine if the documents are forgeries, and they analyze paper, ink, and writing instruments for possible evidence. Education, experience, and licensing requirements for forensic technicians and forensic scientists vary greatly depending on the exact position. Entry-level technicians should
Forensic Pathology Paper Forensic pathologists are interesting to me because they are commonly used when the cause of death of an individual is considered to be suspicious. The role of a forensic pathologist is to establish the cause of death in an individual. They perform autopsies, study and analyze physical evidence that is used in criminal court cases. First, forensic pathologists are physicians, but they must also have knowledge of several other forensic disciplines or sub-disciplines. For instance, forensic pathologists must be able to apply areas of toxicology, firearms examination, trace evidence, forensic serology and DNA technology to their investigations to determine the cause of death of each individual case.
Research Process and Terminology Paper Rachael Gammill CJA 433/Research Methods in Criminal Justice October 3, 2011 Michael Walker Research Process and Terminology Paper Terminology and the Criminal Justice System hold a key to the basic understanding of concepts and prosecution of words. What this means is simply put to be able to transcribe knowledge with his or her words to the case at hand can make the difference whether the case is won or lost. Without being able to translate in the proper terminology the point taken can be lost in a simple mathematical formula given the Hypothesis based on the Criminal Justice System. The Hypothesis will be analyzed throughout the text and will be visited from a statistical point of view in how it determines how a case is handled. Including new terminology learned from the readings begins with the basics from the chapter discussions.
Fingerprints show ridge ending, enclosures, bifurcations, and trifurcations. Shoe impressions, the investigator looks at the heel design and sole design and the manufacturer’s name. Tool impressions is another type of evidence. Tool impressions are nicks, dents, broken edges, and striations on tools. Investigators or criminalistics need to know a few things in order to make the determination that glass was broken from the inside or the outside.
Long after the crime scene is gone, investigators can virtually return to the scene of the crime to test out theories and compare evidence results to an investigation that leads to a confession. The video also shows you a new tool that scans the room and makes a 3D computer model of the scene so that investigators can see the scene later on as well as show a jury what the scene looked like. Forensic science is considered an essential component in the solving of crimes and law enforcement as a whole.
Once the vehicle was secured, the forensics investigators began doing an investigation to determine what type of evidence could be found in the vehicle which could lead to naming a certain individual that had contact with the vehicle. They began doing blood swabs on the gear shift, and fingerprints all over the vehicle. Nothing was found. They then sprayed the vehicle and then used an ultra violet light which made blood and a fingerprint become visible to where investigators could get the evidence for possessing. They found blood on the steering wheel, and a fingerprint on the passenger side door window.
On Ron Goldman's (one of the victims) shirt and inside the knit cap, hairs were also found. The hairs were matched to O. J. Simpson's hair. On the glove found at O. J. Simpson's estate, hairs were found matching the hair of both victims. Usually, hair analysis involves microscopic observation which determines whether the hair samples were human and compares the known hair with the samples observed (Deedrick, 2000). In O. J. Simpson's case, due to the racial factor, investigators also compared the racial characteristics displayed in the known and unknown hair samples.
The technician collects physical evidence such as bullet casings, footprints, hairs, guns, fibers, fingerprints, DNA and clothing fibers. It is the forensic technician's duty to ensure the evidence is collected properly using strict chain-of-evidence procedures such as placing items in separate bags and sealing them tightly. A technician correctly documents all the physical evidence collected by location, nature and type of evidence. One of the duties that a forensic technician does at a crime scene is document the evidence. Documentation of the crime scene involves a variety of activities including photography, videography, and crime scene sketching.
Evidence of the crime scene is obtained, this would include photographs or an in person examining of the scene, a profile of the victim (including their pathology reports), witness statements and DNA analyses of the victim and the offender. The FBI profiler then draws up a classification for the offender based on the evidence obtained. The offender is categorised as either an “organised” or “disorganised” criminal. An organised criminal would is more methodical, feeling more in control of the situation than a disorganised criminal. For an organised criminal, there would be signs that the crime committed was pre-meditated and planned with minimal evidence left behind, they likely would have known the victim and if sexual assault did occur, it would have been while they were still alive.
Several tests may need to be run to figure out what exactly is mixed in. There are several test that police do on scene using reagents that will react with a color if a particular drug is found, but I think that further test need to be done to be sure the full spectrum of what drugs are being dealt with need to be found. * Collecting
