If I strike you in the head with a blunt object, then subsequent to that act stab you, shoot you, and light you on fire, because you were still moving around, the blunt force trauma was not the primary cause of death. One of the other actions would be found to be it. Why? Because you were still alive and there's a chance you might have survived that alone.
Neely was still alive when the first responders found him.
