Firstly condolences to families and friends of the missing. It is a tragic situation and while ch 7 seems to be speculating on "possible sabotage" I think the answer will be more mundane but no less sad.
As to the Cameraman/Journo while not defending their actions in any way, I was wondering if we all saw the footage? Thats the problem, it's a bit hard to flick over and they know we'll watch it. The real dog act was with the Journo who went to the injured womans mums house to ask her questions while her daughter is severely injured far far away. Her stressed response to the questions was a simple " do you have children? " So he kept asking her questions. The old adage of you get the media you deserve just doesn't feel right these days, either that or I'm well out of touch.
