Dr. Alexandrov revealed Dean was shot once in his back from a distance of about three feet.
He stated that the entrance wound was on the right upper back of his body, and the exit wound was exactly above the right collar bone.
This meant that the difference between the exit and entrance wound was significant enough for the wound to be going upwards.
The only way that would be possible, was if the deceased was running, and in an attempt to remove his torso from the line of fire, he bent his upper body down and forward.
He further revealed that he was shot just once with the bullet perforating the right lung causing massive blood loss.
Alexandrov stated that there were no other injuries to the body so the gunshot wound was the only thing to describe what killed him.
