1. Question 5
Match the photos of the victims’ pieces of
evidence, explaining your rationale for
doing so.

2. Possible victims:
Herman Hartono – male, adult  Anya Suriati – female, 9 years old
 Adi Hartono – male, age
unidentified, son of Herman
Hartono

3. Picture 1: Adult’s skull and jaw
 The mandible matches with the skull
 Left and right third molars are present at
the lower jaw. The eruption date for lower
third molar is 17 to 21 years old. So we can
deduce that the skull is an adult’s skull.
 Evidences that show the skull belongs to a
male:
o Rounded supraorbital margin
o Prominent zygomatic bone
o Bone is thicker

4. In conclusion, the skull most probably
belongs to either Herman Hartono or
Adi Hartono since it is an adult male
skull.

5. Picture 2: Pieces of jaw

6.  Previous hypothesis is correct. It is an adult skull due to Lower
third molar is present.
 The angle of mandible is squarish and angular. So it is belonged
to a male victim.
 The right mandibular first molar is chipped and has caries. The
mandible belongs to the victim who has the same dental record
as the mandible.

7.  In conclusion, the mandible belongs to either Herman
Hartono or Adi Hartono. We need further investigation
to verify the victim by comparing their dental records.

8. Picture 3: Child’s jaw
 It is a child mandible therefore
it is belonged to a child.
 Deciduous canine is present.
Eruption date is 2 to 8 years
old.

9. Conclusion: The child mandible belongs to Anya
Suriati as she is 9 years old so mandibular canine
has already erupted.
