I have hunted boar in France, Belgium and Germany and they can be big and take a couple of round to be put down..... But I have never seen a bullet ricochet on their hide! This is crazy.

Oh wait: I just followed one of the link and it says the boar was hit in the head (and died), that the bullet ricochet and hit the motorist at 250 meters.... Not 2 km. The shooter was in a tree stand, his back to the road. The 2 km value was given by the local gendarmes as the practical lethality range of the round....
