Unfortunately for your sentiments, this is a public forum and people on it will speculate and make wild guesses just like they can on other forums or in comment sections in the media. Should they have the time, they have a plethora of platforms on which to comment about this tragedy or indeed, any number of other tragedies that befall people every day.
The only consolation that can be offered is that relatives and friends affected directly by such incidents rarely go to such forums or comment sections of the press media. By far worse are the TV stations who, I believe, do cause considerable upset to those affected as they scavenge for their 'story'.
