The Homicide unit assisted both the investigators and the Forensic Identification unit to gather enough evidence to determine what happened at the crime scene (Huff Post News, 2013). The Forensic identification unit assisted the investigators in determining if the remains that were found in the incinerator, was in fact of Tim Bosma. The forensic scientists evaluated a tooth that they had found, to see if they could gather enough DNA from it to positively identify the human (Adam Carter,
Toxicology and blood analysis is very close but in a way very different in this case of murders. What the toxicology unit does, is test the bodies for anything unusual or stuff that shouldn’t be happening within the human body. Once all the bodies were found buried under Gacy’s yard, every one of them was tested. The reporting officers found out that along with Gacy’s clown costume he was drugging kids when he was alone with them. The drugs were heavy sedatives and heroin which caused the kids to black out.
First off, the main and most commonly known use of forensic anthropology is to catch criminals and protect the living. It can be referred to as giving a voice to those who cannot speak- the dead. As stated in the documentary Secrets of the Body Farm, forensic anthropology was originally
Dead Men Do Tell Tales by William R. Maples chronicles Dr. Maples a forensic anthropology at the University of Florida. The book starts by talking about William maples before he found his career path and love for forensic anthropology. He started by working on an ambulance while in college. One of the most interesting things Maples says in this section is that he learned quickly he was capable of dealing with gruesome scenes this stuck out to me because he made an analysis that had never dawned on me, the people who work these accident scenes see the more gruesome parts of these accidents, by the time these people reach the Emergency Room they are often a much prettier picture, by then the victims often more cleaned up than they are at the
Forensic science has been an aid to the law enforcement community for years now. It has solved cases that were unsolved years before DNA and science started to play a role with cases and law enforcement. The case of Samuel Reeves and James Layne was unsolved in the year 1989, this was considered a cold case because it had been years since they found who the murderer was. This case was considered a crime of passion, where it first started off by kissing and having the same attraction towards each other, but when James Layne started to get aggressive and not respecting Reeves decision to not have sex, that was when things got hectic. Forensic science helped this case by the use of fingerprints, they found the fingerprints in a bottle, and when
A positive aspect of this is that forensic scientists only need a small amount of a sample to get the results they need (“Forensic Science” 12). These samples can come from many other forms of identification other than fingerprints and bloodstains. A few moderate examples include strands of hair, tiny beads of sweat, and a saliva specimen (“Forensic Science” 12). Forensic Science Technicians stated that “crime scene investigators may use tweezers, black lights, and specialized kits to identify and collect evidence.” They also stated that examining autopsies prove to be beneficial in a crime investigation (“Forensic Science Technicians”
There are many important factors in crime scene investigation, one of those involves serology and observing the blood spatters at a crime scene. Many steps are taken when dealing with blood at a crime scene, some of which are if the substance is actually blood, blood typing, discerning the origin of the blood, the direction of travel of the bloodstain, what weapon would have caused the bloodstain, etc. Serology and dealing with bloodstains can be a very difficult task for criminalists because blood also deals with DNA, what type of blood it is, identifying who the blood belongs to, what caused the bloodstain, and what direction it originated from. To understand serology, it is probably best for one to understand the nature of blood first.
Forensic Science is the career field I am interested in. I would enjoy being a forensic science technician because of my interest in mysteries and figuring things out. This career choice is the right choice for me because I would only need a Bachelor’s degree, it would be work I enjoy doing, and I would make an exceptional salary. Forensic science technicians aid investigations by collecting and testing evidence. Many technicians spend time either in a laboratory or on the field in crime scene investigation.
I took all the sciences I could, eventually majoring in Biochemistry in college to understand the workings of the body. I always thought I wanted to be a pathologist. I was aware of pathology assistants but was unaware of what their job entailed. In my junior year of undergrad, I was fortunate enough to find out that my college worked with a teaching hospital, Montefiore Medical Center. Through them, I was able to obtain an internship in the Surgical
Hi, my name’s Donovan. I’m 17 years old and graduated this year with honors. I was raised with Christian values in mind, and attended a Methodist school. I was raised in the Christian faith yet I find myself, as with some of my friends who were raised in the same conditions, we seem to be growing farther away from our upbringing as we age. I find myself simply not understanding as time goes by, a complete polar opposite from the song ‘Farther Along’.
● It can be used to determine if a person is guilty or not. The evidence from forensic can be enough to put a person into prison. ● It can be used to solve old unsolved cases if there is still DNA available from that case. ● Help identify victims in big disasters where the body of the person can not physically be easily
“Forensic anthropologist usually works in three broad categories,” said Texas State professor Jerry Melbye.” A Forensic Anthropologist help examine a human skeletal or decomposed remains in a legal setting to establish the identity of an unknown individual and to help determine the cause of death. A Forensic Anthropology work to find the individual that was murdered or was a homicide. They need to find the biological profile of that person.
Getting a job in forensics takes the ability to incorporate all of the scientific strengths learned and the love for solving crimes. Giving expertise on legal activities also plays a major role in investigating and solving misdemeanors(“Discover Careers in Forensic Science”). Many occupations in forensics can be sometimes labeled as morbid or gruesome. Some of these careers may include, forensic crime scene investigators, coroners, anthropologists, and pathologists(forensic medical examiners)(Palmer). These professions salaries can range anywhere from 50,000 to over 200,000 a year(Kaelin).
DNA in Forensic Science DNA is the carrier of genetic information in humans and other living organisms. It has become a very useful tool in forensic science since it was discovered. In forensic science, DNA testing is used to compare the genetic structure of two individuals to establish whether there is a genetic relationship between them. One example of the use of DNA in forensic science that is important in biology today is comparing a suspect’s DNA profile to DNA that was discovered at a crime scene.
DNA in forensic science The majority of cells making up the human body are diploid cells carrying identical DNA, with the exception of haploid gametes and red blood cells. Several types of biological evidence such as blood and hair are commonly used in forensic science, which is the scientific study of evidence for crime scene investigations and other legal matters. Forensic science is used for the purpose of DNA analysis, this is the analysis of DNA samples to determine if it came from a particular individual. DNA analysis is done by obtaining DNA samples from an individual; next, a large sample of DNA is produced from amplified selected sequences from the DNA collected.
