Sun Down

Two young 13 year old boys set off walking through the woods just as the sun starts to go down, they're alone, they're vulnerable. They almost get to the ending of the tall slender-like trees when Russel steps into something unpleasant... A girl, not looking much older than them.. from what they could see. She was mutilated. Her limbs were severed, her skin almost fully removed. All that was left of her skin, was the face. Russel and Jerome were immediately ill at the sight. They ran off to tell someone, get help, anything. When they brought help back the body of the girl was gone. No blood trace left. Was someone messing with them? Did the boys imagine the whole thing? If someone was messing with them, what kind of disgusting creature could be capable of something like this?
