Part 3: So, how many victims?

  

How do you confirm how many victims are involved? 
Well, we would say only one victim is involve in this case though there are not much evidences found!

Firstly, they only found a whitish object. Despite finding few pieces of jaw-like structures, there are possibilities that all these pieces belong to only one victim!! The victim might have been hit or even punched real hard on their face when they tried to flinch or escape! Despite being one of the strongest bones in the facial region, the jaw can only withstand up to small amount of forces!

Forces that are required to produce a fracture of the facial bones are as follows:

• Nasal fracture – 30 g
• Zygoma fractures – 50 g
• Mandibular (angle) fractures – 70 g
• Frontal region fractures – 80 g
• Maxillary (midline) fractures – 100 g
• Mandibular (midline) fractures – 100 g
• Supraorbital rim fractures – 200 g

However, examination of bones ought to be done to confirm the wild guess! First, reconstruct the bones or skeleton. If there is no disproportion in the sizes of various bones and reduplication, articulation is correct and if the age, sex and race of all bones are the same, they belong to one individual.

How do we determine the nature of the injury?

The ends of the long bones should be examined properly to find out if there have been cut by sharp objects during collection of evidence. Note that the shape of burnt bones is preserved but they become powdery when they are pressed between fingers.

THE END.
