My family came real close to stumbling onto a dead body when I was a kid. We were taking a walk down the railroad tracks with the dogs and started smelling something rotting, figured it was a deer hit on the road about 50ft away. Not wanting the dog to smell from rolling in a dead deer we called the dogs, turned around and went home. Next day they found a body next to that road that had been shot.
After the investigation the police said it was a drug deal gone bad but they didn't know who the shooter was.
