That was pretty damn funny.
The doofus says something like "It was getting dark, I couldn't really see it..." Then he points off in the distance: "It was on top of this hill".
Yet... "the blood trail begins here." Right beside the truck. Right where he was standing.
The driver, shown with a beer in his hand, gets spooked and decides to ditch the scene of the crime... and gets back in the truck with his beer and drives away.
I still don't know what to make of it.
