This story has reminded me of a story my parents told me from the days when they were both coppers.
Essentially called out to a field where there was some guy on his back, dead, blood all around the middle half of his body with his trousers half way around his ankles.
Turns out he was also missing his meat and two veg. After some investigation and what not, turns out he was a bit of a wierdo and had gone into this field to try and make love to the local horse.
The problem being, that when horses are....entered...they clench extremely hard (imagine its "entrance" clamping down on his junk like a vice).
The guy, being stuck to this horse at this point starts to panic, only to panic the horse too. The horse in turn naturally does what horses do and bucks. Problem being, this guy gets bucked away from the horse and everything gets ripped off. EVERYTHING. The horse that was violated also happened to have things still attached when they were investigating the scene.
Essentially junk ripped off, died of blood loss in the field. This was in the 70's so no mobile phones or anything. I guess he would have died pretty fast from loss of blood to that region of his body.
So yeah moral of the story, don't **** horses.
This story is true as far as I know it and has been recanted by my folks to a fair few people so I doubt its a lie. I guess coppers see some pretty messed up stuff.
