Question 5
List the evidences presented to both the doctors.Considering the evidences up to this point, describe in detail how would you go about investigating further, assuming you are Dr Rudi or Dr Suria, explain what you anticipate at each step.
Since these evidences are found in the same vicinity, we can assume that they are related to the same case. Below are the evidences that are available to Dr. Rudi and Dr. Suria:
Evidence 1: Part
of a large jaw bearing five teeth and a skull
Evidence 2: Complete
jaw with some teeth still in eruption
Evidence 3: A
piece of jaw bearing 3 posterior teeth
Hence, we
can safely deduce that there are 3 victims in this case at least.
Below is an animation depicting a conversation between the forensics team, followed by a detailed transcript of the conversation.
Based on the dentition and size of the jaw, we can know whether the jaw belongs to an adult or a young child.
Carry out an orthopantomogram(OPG) to get radiography of the mandible. Therefore, we can know the estimated age of the victim by depending on the maturation of crowns and also transparency of roots.
By using forensic facial reconstruction, we can recreate the imaginary face of an individual either into two or three dimensional by using the skull and large jaw found.
Determine the radiocarbon content in tooth enamel by using radiocarbon-14 dating. Radiocarbon dating works on the principle that accumulation of carbon-14 by the body will stop upon death, and will decay at a fixed radioactive decay rate. Therefore, by knowing the carbon-14 content in the deceased and through calculations, the age and year of death of the victim can be estimated.
According to part 1, Dr. Rudi mentioned that there is ‘Blunt force on the back of the head’. By looking at the size and shape of the injury of the skull (as used in ballistics forensics), we can approximate the weapon used and try to find evidences of the weapon in the vicinity.
Lastly, by cross-checking the list of missing person in few months back, we can narrow down the scope to only a few suspected victims. Then we can interview their family to find out more information related to the case.
