The full live-blogged post is here. More tomorrow as we recover more facts.
For now: a prayer for all those still miraculously struggling for life, for those who are helping them, for those who have been murdered, and for all the families and loved ones affected by this crime. A prayer too for the dark and twisted soul who committed this act, because it is also a Christian duty to see the human in him as well.
And a prayer that, whatever the precise dynamic that brought this evil to the surface, we can get past the violent rhetoric of our time and the poisonous polarization that fuels it. It has been ugly; it has been cruel; it has been reckless.
And it has to end.
