"In this case you have a through-and-through hole of the right ventricle, and then you have a least one hole if not two into the right lung. So you are losing blood, and every time the heart contracts it pumps blood the two holes in the ventricle and at least one hole in the lung. So you are losing blood. If you engage in a struggle, which is what was supposed to have happened, your heart increases. Mr. Martin was a healthy young man. If he was involved in a struggle you expect his heart to be going, beating, especially after he had been shot, more than a 100 times minute." Di Maio said. "You are losing 1,500 cc's in a minute. That's about a quarter of his blood supply. In a second minute, if you can assume the same rate. Actually, the heart would probably be beating faster for the second minute. He is going to lose another 1,500. Well, that means he has lost more than 50 percent of his blood supply."

West asked, "Is this a hard call for you?"
"No, this is basic, you know, 101," Di Maio said.

Di Maio is explaining that if the gun had pressed up against Martin's body the injury and the hole in Martin's clothing would have looked differently.

The pattern of the powder tattooing on Martin's body took up an area about 2 inches by 2 inches.

The pattern of the powder tattooing helps pathologist determine how far away the gun barrel was away from the body when it was fired.
