When I worked for the state, a coworker's son almost went to jail over the potential outcome of a water ricochet. The son was shooting turtles in a pond with a friend. They were well away from the road and houses. Despite that, one of the .22LR projectiles ricocheted and traveled either 3/4 of a mile or a mile (surprised me) to hid a elementary school age boy in the head, causing a severe injury. Luckily for all concerned, the kid recovered after some hospitalization.
I would bet that the son uses a .410 shotgun next time. He was reportedly VERY freaked out when the police picked him up to answer some questions. I am uncertain how they were sure he was the one who fired the ill-fated shot.
