A tragic event but I really don't understand how making a public blog post is supposed to make anything better.
Please read the last paragraph. She didn't want to make this post, but an outcry for details from the community forced her hand.
I really wish I could help this person (assuming the story is accurate, since some HN posters have pointed out that there are conflicting versions) but the only thing I can think of saying to her is to keep it within the circle of persons who are actually concerned by the whole incident, and seek reparations through legal channels. Nothing good comes out of involving a bunch of internet followers. I'd rather a formal investigation was made instead of witnessing a bunch of armchair detectives harass O'Brien without knowing all of the facts. One of my friends has had to deal with false accusations of a similar nature coming from his deranged ex, so I'd like to know beyond reasonable doubt what happened before thirsting for vengeance.
