Why Forensic Biology is Required in Particular Cases (Essay Sample)
the particular case will require forensic biology because it involves murder, which is a serious crime. forensic biology will also be necessary because no human eyewitnesses are present to help solve the mysterious murders. forensic biology will provide critical leads concerning the people who committed the murder. thus, forensic biology requires in particular murder cases.source..
1 Why will this particular case require the use of forensic biology? Explain in detail.
Forensic biology is the use of biological science principles and methods, usually in a legal setting. During a legal inquiry, forensic biologists examine cellular and tissue samples, as well as physiological fluids. These methods are also effective in determining paternity and familial connections. In a legal or humanitarian setting, forensic biology also includes applying archaeology and biological anthropology expertise to retrieve and identify human remains. Excavation, provenience, and chain of custody are all aided by archaeology—biological anthropology aids in the diagnosis and determination of trauma (Gunn, 2019). In most situations, forensic anthropologists are brought in to assist with cases involving primarily bone and little soft tissue. War crimes, mass deaths such as aircraft disasters or earthquakes, mass graves, and genocide are examples of possible causes.
The scenario involves the identification of five skeletons that have been found in a ground opening. Forensic biology is involved in the identification of human remains and establishing any family ties to the remains. When human remains or a possible burial are discovered, forensic anthropologists are called in to collect information from the bones and their retrieval environment to figure out who died, how they died, and when they died. Forensic anthropologists are experts at examining hard tissues like bones. In assisting in identifying victims and supporting criminal investigations, forensic biologists study blood and other body fluids, animal, plant, insects, bones, hair, other body fluids, and remnants (Trail, 2021). Forensic biologists gather and examine biological evidence discovered on weapons, clothes, and other surfaces using technologies in the lab and field to identify the time and cause of death. They keep meticulous records and make reports on what they discover. Because a single blunder might lead to the evidence being thrown out of court, meticulous attention to detail is essential. Senior forensic biologists may be called to give testimony in court regarding their results. This case involves a police case, and therefore, the need to acquire enough evidence from the remains is required for court litigations (Butler & Willis, 2020). Forensic biology is required to assist in identifying and laying any links to the families or relativeness of the deceased.
2 When you arrive on the scene, what is your first course of action? Describe your process, and be specific.
When cops recognize a crime location, it is their obligation to set up a border around it to forestall tainting the scene, which may risk the proof. The anthropologist then, at that point, shows up on the site to distinguish the human remains. The presence of an anthropologist is basic since they are fit for recognizing body stays, paying little mind to the age of the crime location (Gunn, 2019). The person would then be able to embrace extra examinations on the spot by utilizing unearthing to find any covered remaining parts minus any additional harming them.
An anthropologist's first course of action is to take pictures and videos of the condition. Gather proof materials, especially from conceivable passage destinations. Swab areas of conceivable contact to gather low-level DNA proof. Different items that might convey hereditary proof ought to be accumulated (Trail, 2021).
1 How will you avoid contamination at this stage of the investigation? Explain.
Any foreign substance brought to a crime location after the wrongdoing has been carried out is alluded to as defiled proof. Examiners, cops, firefighters, crisis responders, casualties, suspects, and Witnesses, would all be able to carry tainted proof into the examination. To avoid any form of contamination to the evidence, anthropologists must observe several sett precautions (Toncic & Silva, 2021). These may include;
* Put on your gloves. They ought to be changed regularly.
* Before and after dealing with each example, utilize expendable instruments or completely clean them.
* Avoid contacting where you figure DNA could be available.
* Coughing, wheezing, and talking overproof is not a smart thought.
* When assembling and pressing proof, try not to contact your face, nose, and mouth.
* Allow proof to air dry totally before pressing.
* Do not place proof in plastic packs; all things considered, place it in new paper sacks or envelopes. Staples ought not to be utilized.
2 How will you control the other first responders or law enforcement officers? What challenges do they pose to a forensic investigator? Explain.
Law enforcement officers and the first responders need to be notified that they should keep off the crime area as they may interfere with the evidence. For instance, any action by the first responders and the law enforcement officers has the potential of contaminating the evidence. Forensic biology relies on the DNA and other examinations on the specimen to analyze the case. In this case, coming into contact with the bones might interfere with the DNA results. This is because the investigation aims to establish any contact points by the last person (Basset & Castella, 2019). Their information might be detected in the crime evidence, thus complicating the matter further.
Before notifying the police of the scene, the first responders might have interfered with the evidence. When one of the men fell at the hole, he might have interfered with the original setting of the evidence. The rule of thumb in forensic investigation is that the evidence should never be interfered with and should remain at its initial position. The police to ascertain the crime scene might have touched several areas in the scene. This may lead to interference with the evidence in the case (Toncic & Silva, 2021). Interference with the original nature of the evidence is the main challenge that anthropologists face in conducting forensic investigations.
3 What will you do to identify the remains at this crime scene? Explain.
The confirmation of whether the bones are undoubtedly human bones is a significant stage in the criminological examination. Numerous creature bones are remarkably like human bones. From that point forward, the scientific anthropologist will look at the unresolved issues and organic profile. The remaining parts found at the underground opening may be stirred up with those of different creatures, debris, and jetsam, or creepy crawlies. The solitary individual who can recognize the distinction between human and non-human bones is an anthropologist (Osborn-Gustavson et al., 2018). Following the distinguishing proof of bones, the anthropologist examines extra remaining parts, for example, delicate tissues, to decide how long they have been in the scene by assessing the pace of decay utilizing taphonomic investigation. The assessment depends on a logical idea that shows that the more a bone is presented to air, the quicker it decays. Subsequently, taphonomic assessment can be utilized to appraise the period an individual has been expired. It likewise distinguishes any activities that affect the body, regardless of whether physiological from general climate. This is cultivated by natural rebuilding and the partition of components that happened before, after the fact passing. The master then, at that point, inspects any remaining delicate tissues, like filaments, which may be a wellspring of data (Turingan et al., 2020). Regularly, the anthropologist will complete the assessment by similarly adjusting the bones as a human body.
After the human remains have been recognized from different things, there is the need to distinguish the people. At the point when remaining human parts are found, there are three essential logical methodologies for figuring out who they have a place with (1) Fingerprint investigation, which analyzes the examples of skin on the tips of the fingers, (2) A dental assessment that inspects the teeth just as any dental treatment, like crowns and fillings and (3) DNA assessment, which looks at DNA profiles found in delicate and hard substantial tissues (Osborn-Gustavson et al., 2018). This information results would then be coordinated against a data set of DNA, dental, or unique mark records.
3 What is the documentation process for collecting and preserving this type of evidence? Explain.
All through the investigation, documentation is a constant interaction. Although there are covers and equals in the computerized and actual legal examinations, it is basic to precisely report the area and condition of capacity media, PCs, other electronic hardware, and formal proof (de Leeuwe, 2017). A portion of the documentation measures that might be utilized in the assortment of this kind of proof might incorporate recording, still photography, and crime location outlining.
A camcorder, in case one is accessible, is the underlying advance in catching a crime location. Tape can give you a perspective on the crime location design that photos and drawings can't generally give you. It is a more normal survey medium to which individuals can interface, particularly regarding introducing the design of the crime location and how the proof connects to the wrongdoing. A completely energized battery ought to be remembered for the camcorder, just as date and time tape show highlights. Discretionary components incorporate a title generator and "shake-free" activities (Murray et al., 2018). Except for markings p...
