It was pretty heavily reported on much of the media. The story came out maybe a few days after the shooting. I know with time people tend to forget this but the story that Cassie Bernall, Rachael Scott and another girl who survived being shot was pretty heavily reported atleast in the Denver papers and much of the conservative christian media.
It actually came out that same day. A lot came out during the event and through the same day (on Denver TV anyway) that later turned out to be exactly right. I've learned to trust what I hear first from people who are on the scene of an event, not what comes out later after the media gets their hands on it.
