Quote from link - "One called the victim a "true hero" describing the attempted rescue as "a true act of bravery" and an "amazing act of kindness to save two other lives".
You may have noticed that casual use of superlatives is one of my hobby-horses ;-)
It is a shame that they now have to add 'a true hero' to stories about genuine heroism, to differentiate it from all the bogus ones that the media foist upon us.
