Forensics Quiz

The bullet entered on the lateral side and traveled through the frontal plane on a 45 degree angle. First, the bullet likely went past the 8th rib and fractured it. The bullet was misdirected from the impact and came out around the umbilical region. The bullet would've gone through the heart causing massive internal bleeding, which would've caused the death. This diagnosis is best as it provides a short route for the bullet and is most plausible in route.

Other possible diagnoses:

1) Death from obstructed breathing: this diagnosis is implausible because with the suggested path of the bullet based on the injuries, the bullet would have not passed through the lungs. 

2) As the exit wound shows signs of a fragmented bullet, one possible diagnosis is that the bullet split up and damaged a wide range of organs, causing massive organ failure and eventual death. This theory could be checked by thoroughly checking all organs for signs of bullet penetration.

3) It is possible that the bullet would've fractured multiple ribs and perhaps affected the pelvic bone or spinal cord, causing the man to fall to the ground and not be able to get to help before bleeding to death. This could be again be check by thorough checking all ribs, bones, and surrounding area.
