After killing several wolves, my friend died due to the remaining few from the pack. He got a spawn right near where I was parked with an Olga on the coast, and we drove straight there in under 20 minutes. By the time we got there, his body and the wolf bodies were gone.
If we are to imagine that the wolves devoured his corpse, then the clothes, equipment and bones should remain behind. If we are to believe the wolves dragged his body away, there should be a blood smear on the ground.
