Recommended: Essay on the history of forensic science
Forensic medicine was recognized in the early 19th century and is still being used today. Forensic medicine deals with the application of scientific medical knowledge to the administration of law, to the furthering of justice, and to the legal relations of the medical practitioner. Forensic medicine addresses the physiology of dying, the cause and time of death, and post death phenomena. Practitioners of this branch of medicine assist the law in assessing the liability of medical practitioners in issues including consent to treatment, therapeutic intervention, emergency treatment, legal procedures, tissue and organ removal and transplantation, unnecessary surgery, cosmetic surgery, scientific experimentation, and sexual procedures as well …show more content…
Forensic medicine has come a long way since its inception. Contemporary postmortem examination is an integral part of criminal investigations and involves both gross and microscopic analysis of organs and tissues for the development of legal records and, if indicated, testimony in a court of law. The most common type that is still being used is the autopsy and this could be used to find the identification of the dead and also the cause of death. If the death was caused by a weapon the Forensic Pathologist can figure out detailed information about the type of weapon and other important information. If the death was caused by a bullet the Pathologist can find the angle of fire and also the accuracy. Forensic Medicine is a major factor of the identification of victims found in disaster. In the 19th century two other forensic specialties arose; forensic psychiatry, and forensic toxicology. Forensic Psychiatry is used to determine the mental health of an individual before standing trial. A Forensic Toxicologist gives evidence on topics such as intentional poisoning and drug …show more content…
Autopsies are used to determine the cause and manner of any death that is violent, unusual or untimely. The pathologist will examine the dead body remains and consider death scene findings. They will look at the medical records to see if the death was actually caused by a crime or from another reason like natural death. They might find something during the autopsy such as a bullet and this can help determine the cause of death and the manner at which it happened. They look at the bond pattern to see if they can find the type of weapon that was used and try and match it to a weapon.
Forensic medicine was discovered in the 19th century and has been used since it was discovered until today. The autopsy is one of the most commonly used types .An autopsy is a thorough medical exam of a body after death. It may be done to learn about a disease or injury. Or it may be done to find out how or why a person has died. An autopsy is done by a doctor called a pathologist. This type of doctor is an expert in examining body tissues and fluids. Family members may ask for an autopsy to be done after a loved one has died. This is called a requested autopsy. Sometimes an autopsy is required by law. This is called a required
The pattern that the blood gives off gives forensic scientists the tools that they need to help solve cases. Investigators can find clues to a murder in a number of different ways. Typically they find out how many times someone has been stabbed or how many blows they received. Through the count of the times the action had been performed, they can come to an understanding of whatever hand the suspect was using. Other information can tell how the suspect was standing over their victim during the time of death.
A psychological autopsy is an investigative technique, usually employed by psychologists, which is used to determine how death had occurred in equivocal death cases (Fulero & Wrightsman, 2009). This technique is used to try and understand the mindset of the deceased person to help answer certain questions like why did the individual do what they did and why did it occur at that time? The investigator will collect data about the individual, like written correspondence and journ...
Forensic pathologists are the people who determine the cause and time of death if the deceased person died under suspicious circumstances, whether they be violent or not. They determine if the death was accidental, a homicide, natural, a suicide, or even if the cause of death was unknown. They do this by studying said victim’s medical history, evaluating the crime scene for evidence, studying the body for any clues, and performing an autopsy. After determining the cause, time, and the manner in which the victim died, forensic pathologists make a written report on the victim and sometimes testify in court to report their findings.
When a death occurs suddenly, unexpectedly and from unnatural or unknown causes, a forensic scientist has the duty to gather and analyze evidence to determine whether the victim died from a previously undiagnosed disease or infection or from a homicide, suicide or accident (Lurigio, 2009). When considering suicide as the probable cause of death, we are looking at the act of intentionally killing oneself through one’s own effort or with the assistance of another (Sever, 2009). The resolution of the manner of death by a forensic pathologist as suicide is based on a series of factors which eliminate natural causes of death, homicide and accident (Geberth, 2013, p.55). The cause of death is also determined by the medical examiner in conjunction with the crime scene investigator; however, it can only be determined after a thorough investigation is concluded. Therefore, in the complicated process of doing a death investigation there are several mistakes that should be avoided, which are discussed in Geberth’s article, Seven Mistakes in Suicide Investigation (2013). Mistakes in doing any death investigation affect the integrity of the evidence in determining the cause of death and in its admissibility in court.
The sudden or unexplained death of a person has a huge impact on families and friends of the deceased, and it places a huge role of responsibility on the medical examiner to answer questions which may provide closure. Interaction with the loved ones of the deceased is a delicate matter that must be dealt with calmly and professionally. Generally, medical examiners are overachievers, objective, analytical, and optimistic. “I can’t do anything for the deceased, they’re gone. But if I can do anything for the family, I will.” (www.voxmagazine.com)
In all cases in which the cause of death cannot be determined, a medico-legal autopsy is done. In a nutshell, a medico-legal autopsy serves to help explain a legal question surrounding the death in question e.g. is the manner of death natural, unnatural or undetermined? Was someone else involved? What were the circumstances leading to death? Therefore, in addition to the results and findings of the autopsy, other findings such as those from the crime scene also play big role in helping to determine what really happened.
When a person's body decomposes after death, it goes through a series of stages involving different chemical changes that cause it to change its appareance. Observing these changes can help forensic scientists determine the post-mortem interval (or time since death), which is very important when it comes to investigating unnatural deaths.
The word “Death” has connotation meaning to it. Many are afraid of the unknown, but others are fascinated. If there's death there must be a body to claim. The career of a Medical Examiner focuses on dead people. This is the next step of my journey I would like to accomplish. Due to the career research project I was capable to expand my knowledge and reflect about my future career. In this research I was able to acquire more information a about what a Medical Examiner is, the requirements and it's income.
Forensic science plays a vital role in the criminal justice system by aiding an investigator’s case with scientific information based on the analysis of the evidence. Each crime scene is unique in its own way and using the evidence collected, forensic experts try to piece it together. An expert is someone who has had enough education, training, and experience to testify to the matter at hand (Harmon 2010). Unlike other witnesses in a case who testify based on first hand knowledge, the expert witness is not required to have firsthand knowledge of a particular case, and in fact, often does not. Rather, the expert witness testifies to the meaning of the facts (Whitcomb et al. 2005). Each forensic expert typically has a background in another scientific discipline, such as biology, physics, chemistry, etc. An expert with a biology background may work with DNA; chemistry may work in toxicology; and physics in blood spatter trajectories. Working separately on their own respected evidence, an investigator is able to collect all their data and set up a case (National Institute of Justice 2013). Usually, these experts will be hired by either the prosecution or defense in a criminal trial, or by a plaintiff or defendant in a civil litigation. The role of the expert witness exists in variants: between criminal and civil courts as well as the prosecution and defense.
The term forensic toxicology is defined as examination of all aspects of toxicity that may have legal implications (James & Nordby, 2009 p. 61). In the past, poisoning was one of the most popular forms of murder. There are countless natural substances in the world that when ingested into the body in high doses, can become lethal to the human body. What made this form of murder so famous is that most poisons mimic common medical diseases, leading physicians to believe a victim died of natural causes (Ramsland, n.d.). Aside from murder, this forensic discipline is also essential for determining accidental deaths and suicides.
When a suspicious body appears in the morgue, the forensics team goes to work. The body, if still covered in tissue goes to the forensic pathologist who will study the tissue extensively. If a conclusion is unable to be reached through this process, the pathologist will remove the tissue from the bone and send the skeleton to the forensic anthropologist. In other cases, the victim is found with no to little tissue on the bone, making it nearly impossible for a layman to discover any identifying characteristics about the person. The forensic anthropologist’s first job is to determine the sex, age and race of the victim (Sauer, 1998).

Blood stains are one type of evidence that can be found at a crime scene. Blood that is still in the liquid form should be picked up on a gauze pad. Once the blood is dried thoroughly it should be refrigerated and sent to the Laboratory (Andrus et al., n.d., para. 1). If the blood stain is found dried on clothing, the officer should wrap the piece of clothing in clean paper and place it in a sealed and labeled container. An object with dried blood stains needs to be sent to the Laboratory if it is small enough. If the object is too large to send, then using a clean knife the stain needs to be scraped onto a clean piece of paper, which then can be folded and placed in an envelope (Andrus et al., n.d., para. 2). When collecting autopsy blood samples, the officer should request that the pathologist obtain the sample directly from the heart and place it in a yellow or purple stoppered vacutainer. If the victim is still alive but in serious need of a blood transfusion, then the pre-transfusion blood sample needs to be obtained promptly before the hospital discards it (Andrus et al., n.d., para. 4). It is important for the Laboratory to receive all blood samples within 48 ho...
Forensic toxicologists employ a large number of analytical techniques to determine the drugs or poisons relevant to an investigation; the capacity of a laboratory to conduct routine toxicological analysis varies depending upon equipment, technical capability and analyst experience. When needed, there are specialty toxicology labs that can test for almost any potential toxin or metabolite in almost every kind of post-mortem sample. A laboratory should be accredited to perform the analytical work and must be subject to regular inspections. This will ensure that laboratories can reproduce accurate and reliable results for investigations. All laboratory tests conform to standard operating procedures, results are confirmed to meet standards, and reported results are peer reviewed by a second toxicologist before being released. Even so, we still use methods that Gettler used in his
As far back as 1832, James Marsh was the first to use forensics at trial to give evidence as a chemist in 1832. Since that time forensic science and evidence has come a long way in various ways and technology to help in determine if the suspect is guilt or not, through such things as DNA testing, blood, and fingerprints. The first forensic police crime lab was created in 1910. The contributions of Dr. Edmond Locard, a French scientist and criminologist, proposed that “everything leaves a trace”. This principle is still valid today as it was so many years ago. No matter how small, the specialized trained technicians and investigators can take these methods and go to a crime scene to get evidence. “Forensic science is the application of sciences such as physics, chemistry, biology, computer science and engineering to matters of law.” (Office of Justice, 2017) These different sciences can help achieve and assist in solving a case. Forensic science has also the ability to prove that a crime was committed, it can find the elements of the crime, it can help place the suspect at the scene and whether the suspect had any contact with the victim. However, in the last several years the techniques and with the use of technology the evidence that forensic science uncovers can also exonerate an innocent individual who has been falsely accused of the
