I've been out of state for the last three weeks with no time to get online. I saw this event on the local news while out of state and, like the rest of us, was horrified.

I apologize if this has been covered already, but I'm adverse to reading back through 300+ posts. Do we know if any of the victims or those at the location at the time of the shooting were members of this site? What do we know about the perpetrator as to motive? All I've heard about him is he's still alive and his name.
