Wow. What a way to depart this earth. I always suspected that Steve would go with some horrible accident while filming - he got a "little too close" on more than one occasion. But to get stung by a stingray directly in the heart.... Wow. I'm sure he didn't live long after the sting, but it had to be some unimaginable pain. And to not be able to scream while you are underwater! What a nightmare!
All the best,
Glenn
