Was he hugging the stingray? (Score 1)

Was explaining to my 6-year old that the Crocodile Hunter had passed away, and during my son's normal questioning on how a stingray can kill a man, the natural question was asked - how did the animal sting his heart? Was Steve hugging the stingray or something? Might be one of those unanswered questions ... except maybe the cameras were probably rolling at the time of the accident ...
