Description

Listed below are the details outlining a crime scene that occurred over a period of time. You are to investigate and evaluate the crime and be prepared to present your information in a court in the form of a written document. You will have to use entomology, odontology, anthropology, pathology, and microbiology techniques to complete your investigation.

Carl and Joseph were in the woods of Georgia in early fall. They had set up a camp because they were both deer hunters. In the fall of years when the weather is cooler, deer are very prevalent. On this cool November morning, the men were walking through the woods in their quest for deer. On the second day of being in the woods, walking through what was really thick brush and uneven terrain, one of the men slipped and fell into what appeared to be a covering of a hole in the ground. As he began to try and pull himself out, he saw several skulls and bones lying around. He immediately screamed for his friend, who assisted him in getting out of the hole. Together, they looked in and saw skeletons and what appeared to be a decomposing body. 

The two men called the local police. The police arrived, secured the area, and called for the forensic team to come and investigate. You are the forensic person that has been asked to identify the 5 skeletons in the grave and the body that was only partially decomposed.

Why will this particular case require the use of forensic biology? Explain in detail. 

  • When you arrive on the scene, what is your first course of action? Describe your process, and be specific. 
    • How will you avoid contamination at this stage of the investigation? Explain. 
    • How will you control the other first responders or law enforcement officers? What challenges do they pose to a forensic investigator? Explain. 
  • What will you do to identify the remains at this crime scene? Explain. 
    • What is the documentation process for collecting and preserving this type of evidence? Explain. 
  • How will you transport your evidence to the lab safely? Explain. 
  • Once you arrive back at the lab, what significant risks of contamination exist? Explain. 
    • How will you avoid this contamination? Explain. 
  • What is the process for DNA analysis on the decomposing body? 
    • What specific tests will you use? Explain. 
    • How will serology play a role in the selected testing processes? Explain. 
      • Using this decomposing body as an example, what is the process that you will follow to properly conduct this DNA test? 
    • What challenges or barriers exist when you begin to interpret the results of your DNA test? Explain in detail. 
  • How large of a role will facial reconstruction play in this investigation? Explain. 
  • Next, provide 2 scenarios of court case outcomes regarding this investigation. 
    • One scenario must result in the successful identification and conviction of the perpetrator. You will need to fill in the blanks with regard to physical evidence and other necessary details. 
    • The other scenario must result in a wrongful conviction. You will need to identify the elements that lead to this wrongful conviction.

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

3
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.

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).
o

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

4
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.
o

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 mig...
