Keep in mind, in our society... Blame has to be placed on someone whether or not they had anything to do with it. Long gone are the days where personal responsibility trumps all.
While I don't have ANY info into the family dynamic, I can tell you that in circumstances like this - the medias only care is to simply aggrandize themselves in an attempt to generate ratings at the expense of someone else's tragedy. It is a shame but then again, we live in a shameless society where profit trumps responsibility.
