Yes he was filming a video about "Killers of the Deep" when he was killed, but they say it is ironic that it was a stingray that killed him, because they are actually among the most docile underwater beings. Their barbs at the base of their tale is just purely for self defense and what happened was that Steve was swimming directly above at the back of the stingray, about a foot or less above and apparently the ray got spooked and arched upwards ... and Steve was positioned just by a fluke that the barb went directly into his heart. Had it hit him in the arm or leg or even stomach it would've violently hurt, but he well could have survived. But to take a hit directly into the heart was too sudden and there just was no chance, he died instantly.
So there is video footage up to and including his death, but his company headed by his grandfather aren't sure yet whether they are going to air it or not. Maybe later...? I heard also that Australia wanted to give him a state funeral but his father declined saying that Steve was just a common person and wouldn't want all the fuss over his death.
It's all just so sad.
