First, I find it difficult to understand how a golf ball became covered in blood from knocking out a person. Given the nature of this accident, it
seems the ball would have had to entered her skull cavity in order to acquire the blood. It's safe to assume the ball likely hit the victim, then
bounced off her head. Her head then began to bleed. Of course, she may have fallen next to the ball covering it with blood.
More importantly, it remains unclear if the player received a penalty stroke for picking up the ball and dropping it. I would guess he did because the
location this occurred is probably considered out of bounds. In this case, the golfer was likely agitated by the penalty stroke, which may have led to
his callous behavior of not attending to the unconscious victim.
At the end of the day, I believe if you choose to live near/on a golf course, you are aware and accept the potential consequences. Imagine living at
the end of an airport runway and something goes wrong.
USGA Rules and Decisions
19-1. By Outside Agency (Any agency other than either the player’s or opponent’s side, any caddie of either side, any ball played by either side
at the hole being played or any equipment of either side,)
If a player’s ball in motion is accidentally deflected or stopped by any outside agency, it is a rub of the green, there is no penalty and the ball
must be played as it lies, except:
a. If a player’s ball in motion after a stroke other than on the putting green comes to rest in or on any moving or animate outside agency, the ball
must through the green or in a hazard be dropped, or on the putting green be placed, as near as possible to the spot directly under the place where
the ball came to rest in or on the outside agency, but not nearer the hole, and
b. If a player’s ball in motion after a stroke on the putting green is deflected or stopped by, or comes to rest in or on, any moving or animate
outside agency, except a worm, insect or the like, the stroke is canceled. The ball must be replaced and replayed.
27-1. Stroke and Distance; Ball Out of Bounds; Ball Not Found Within Five Minutes
b. Ball Out of Bounds
If a ball is out of bounds, the player must play a ball, under penalty of one stroke, as nearly as possible at the spot from which the original ball
was last played (see Rule 20-5)
