The analysis of the different skull are:
Figure 15
a. Potential projection trauma, possibly caused by a bullet.
b. It does not match as the description indicates that the teenagers shot the victim in the chest, not the head. However, it's plausible that they aimed at the fallen body and missed, resulting in the bullet passing through the head.
Figure 16
a. Appears to be minimal blunt force trauma; no penetration or open wound is evident, unlike Figure 15. The injury could be a result of the victim being pushed or falling at an angle, impacting the head.
b. Possibly occurred if the victim had fallen.
Figure 20:
a. Possible bullet-related injury, resembling an X-ray relevant to Figure 15. Speculation: the bullet may have grazed this part of the skull.
b. No, like figure 15, this does not match since it is stated that the teenagers shot the victim’s chest. However, it appears that there is a gunshot injury in this evidence.
Figure 17:
a. Combination of sharp force trauma and complete fractures, possibly caused by shear force from a weapon like an axe.
b. Likely matches; the injuries could be consistent with the victim being run over twice with a car.
