Heroes and Heroes that get missed

I do not mean to minimize what Mr. Autrey did. His heroism -- and it is heroism -- has been all over the news; it even was discussed on a BBC newscast (as news that they told on the hour and half hour). There is even an article about him on on the BBC's website.
But, over the summer I heard about Alberto Medina, who jumped into a river to save a boy that he did not know. Mr. Medina died (the boy survived) -- he certainly was a hero for saving someone he did not know -- but the most I heard about it was on an NPR story. Perhaps the danger was not as obvious as diving in front of a subway train is, but I also think that Mr. Medina was a hero.
