Question 5 (Part 3): Matching the Photos of Victims with Evidences

Question 5!

Here comes the most exciting part of the investigation…to match the evidences collected with their respective victims. Although we still can’t be 100% sure whether our hypothesis is true, we are coming closer in resolving the case.

Below is the list of possible victims that might be involved in this case.

• .       Herman Hartono
• .       Adi Hartono (son of Herman Hartono)
• .       Anya Suriati (9-year old twin sister to Tanya Rosilawati)

So let us start from evidence one! As we have mentioned above in question 4, the most significant feature we can see from evidence one is the presence of third molar on both left and right side of the mandible. The shape of the skull which portrays rounded supraorbital ridge leads us to conclude that the skull belongs to a male victim. Hence, we can now say that evidence one can be the remnants of either Herman Hartono or Adi Hartono who have both reach adulthood.

Evidence 2 shows the presence of three molars on the right side of the mandible which is a distinct feature of the jaw. Besides, the angle of the mandible is more acute with a prominent gonial eversion. All these features lead to the conclusion of a male adult victim. Therefore, there are only two possible victims that we can consider, which are Herman Hartono and Adi Hartono.

Evidence 3 shows a child’s mandible with erupted mandibular canine. Due to the low resolution of the picture, we couldn’t distinguish and confirm whether the canine is a deciduous or permanent canine until a detailed study of the tooth morphology is done. However, in this case we can assume that it is a permanent canine as permanent canine erupts at the age of 9-10 years old. Besides, Anya is the only possible child victim that we have, thus we can deduce that this jaw belongs to Anya Suriati who is 9 years old.

In conclusion, the only victim that we can confidently match the evidences is Anya Suriati. Further investigations certainly need to be done to differentiate between Herman Hartono and Adi Hartono’s remnants.
