What you're looking for can be found here, the Who Will Die series.
All that gives is a brief statement that these events happened...and actually does not address my questions at all. It says Statesman is missing, not that he's been killed. It says that a member of Freedom Phalanx must do the unthinkable, not that Manticore kills Sister Psyche.
And I see no mention of Miss Liberty being killed.
I did say that I already searched Paragon Wiki, yes? Out of courtesy I looked again. I already know these events happened. I'm not looking for more statements that they happened... I'm looking for the story.
