Two hunters are in the woods when one of them collapses. But wait for the reaction

Two hunters are out in the woods when one of them collapses. He doesn't seem to be breathing and his eyes are glazed. 

The other guy whips out his phone and calls the emergency services. He gasps, "I'm in the middle of nowhere and I think my friend is dead! What can I do?" 

The operator says "Calm down. I can help. First, let's make sure he's dead." 

There is a silence, then a gunshot is heard. 

Back on the phone, the guy says "Okay, now what?"
