None of Trayvon's blood is on George.
Zimmerman had Martin's blood on him.
But Trayvon took a bullet right to the heart and lungs and then got up quickly enough to avoid bleeding on George?
Martin's blood collected in the spaces surrounding his lungs. The ME collected 2.5 liters of blood from this area alone - which is nearly half of his blood volume. At least one statement from SPD that observed the body noted the lack of external bleeding.
